BMW’s ActiveHybrid 5 Series is the first two mode hybrid from the brand. Unlike the X6 and 7 Series Hybrids (one was a learning tool codeveloped with Mercedes Benz and GM , the other is barely a hybrid) the 5 Series Hybrid follows the typical formula of two drivetrains that can work together or separate using a battery pack to supplement engine drive. There are some key additions to this formula that makes this a uniquely BMW solution.

First, let’s look at the facts. The ActiveHyrid 5 Series marries the familiar N55 TwinPower in-line six with an in-house developed electric drive system and the excellent and equally familiar ZF sourced 8-speed auto. The system gives the car an extra 35 hp over the standard 535i 300hp and allows the car to be driven on electric power up to 37 mph for 2.5 miles.

Interestingly BMW hasn’t dialled up efficiency as much as it could have. Johann Kistler, 5 Series Product Manager, told us that BMW couldn’t forsake performance on a car like this and wanted to find the right balance between the two. Zero to sixty happens fairly quickly at 5.7 seconds. That’s nearly equivalent to a standard 535i but the 5AH has quite a bit more weight to lug around.

The N55 is slightly detuned from its typical 300 hp output as the electric drive system develops 54 hp and makes 155 lb-ft of torque (all available from start). A quick check of the math would indicate that the N55 is making 281 hp. Clearly as much as BMW likes performance out of their hybrids they have made some concessions for greater efficiency.

The electric motor is integrated into the housing of the 8-speed automatic transmission, saving space. The connection point between the two is controlled by a separate clutch. The 54 hp and 155 lb-ft of torque is powered by a high-performance lithium-ion battery, specifically developed for the car. 96 cells and with a energy capacity of 675 Wh, the entire system is enclosed in special high-strength housing positioned directly behind the rear seats and between the rear wheels giving it optimal protection and helping balance weight.

How long will the batteries last? I pressed Mr Kistler on this and was given a surprising answer; the life of the car. He reaffirmed my question by explaining, BMW intends to offer a full life-time warranty on the batteries. Long-term testing inside BMW has proven that the batteries will be fully functional long after the car has likely been sidelined by other issues.

Having this much electronics in the new AH5 presented some unique problems. While the car has a typical 14-volt power supply, it also has a high voltage supply with 317 volts. Both are linked by a transformer that connects the system and transfers power appropriately – be it used for driving or comfort. Additionally the air condition is also fed from the lithium-ion battery pack via the high voltage supply. This allows the aircon to be entirely operational in full electric mode or even when the car it off.

The result is about 12-13% more effeciency over the 21/31 mpg figures from the 535i. That would give the AH5 approximately 24/35 figures or 2/3 mpg higher than even the highly efficient four cylinder 528i. Those are tangible results and real reasons to consider the AH5 if you’re aim is the best combination of efficiency and performance out of a medium sized luxury sedan. For comparison sake the Lexus GS hybrid is rated at 29/34 mpg and has all the performance characteristics of a canister vacuum cleaner.

But that doesn’t mean that the AH5 doesn’t have some exclusive technology when it comes to efficiency. In town that means allowing 100% electric use for up to 2.5 miles and up to speeds of 37 mph. A new development in the AH5, on the highway, the electronics can switch off the engine and fully decouple the drivetrain while coasting at speeds of up to 100 mph (160 km/h). This coasting mode combines comfortable driving with optimum utilisation of the kinetic energy already generated.

This is accomplished in ECO PRO mode which dials back throttle response and dials the efficiency up as high as possible.

While ECO PRO sounds great, it’s not the driving experience some of us would associate with BMW. From my experience in driving the car it only really made sense in town where speeds are slow and acceleration is limited.

Switching from ECO PRO to Sport and then Sport+ turns the AH5 into the car we’ve all come to know. Along with suspension and steering settings the electric motor also changes pace a bit. The extra 54 hp and 155 lb-ft helps deliver properly quick pace – almost as if the engine had an extra turbo bolted on somehow.

What about push to pass functionality? BMW doesn’t see this as fitting in with the regular 5 Series. Additionally the function would use up the stored energy and not allow the car to operate purely on electric power.

Also in the AH5‘s bag of ECO tricks is the levering of the navigation system to help with efficiency. The navigation system analyzes the driving conditions based on the route ahead and alters the make-up of power from the car. For one this allows the car to virtually see into the future and select the most efficient gears possible. But it also allows all drivetrain systems and the in-car electronics to be managed appropriately so that energy can be used as needed or stored in preparation for what lies ahead.

It sounds great but in practice it’s actually even cooler. Take for example, a hilly section of road. The computer will see what’s coming up and invest all the battery’s energy going up knowing that it’ll be able to recoup it all on the decent. It’s exactly this kind of combining of technologies that makes the AH5 so interesting. Among many other eco features the AH5 also features BMW new start and stop system for the 8 speed automatic. The function provides surprisingly seamless operation when the vehicle is stopped in traffic. Perhaps the most seamless thing about the ActiveHybrid 5 is how it moves from electric to petrol power. So subtle is the transition that you simply won’t notice it unless you’ve got the radio off and are paying attention.

Thankfully BMW will make sure you’re aware of the changes via a special function within the car’s 9.2-inch display that shows energy flow and recuperation. Additionally there’s a gauge next to the tachometer which shows the boost being provided by the electric motor during acceleration. Finally a display in the computer screen shows the battery’s current charge level and the power-sharing between the internal combustion engine and the electric motor.

Despite the cool tech, the AH5 isn’t likely to sell in large numbers in Europe with BMW’s impressive range of diesels there. In fact BMW admitted to us that they see sales breaking down in thirds – a third in the US, Japan and the rest of the world. What about China? BMW will likely be launching a plugin model of the AH5 there later this year. But that plugin architecture won’t be sold in other markets. For one the long wheel base 5 Series, which the plugin will be based on, is a crucial ingredient due to the extra space in the trunk. BMW also doesn’t feel that the performance of the car will be what traditional BMW buyers (ie ones in other markets) will expect.

So why a hybrid over a diesel at all? While part of it surely is marketing, there are also some real reasons that one might choose the AH5. For one the petrol powerplant is the same N55 that is continually acclaimed on this site and others. And that means buyers of the AH5 will have a car that can rev and perform like a 535i with less emissions and lower MPG. Even if a diesel equivalent was more efficient it wouldn’t have the high revving characteristic many of us prize in our cars.

Additionally, the AH5 works exceptionally well in tight urban environments where the electric motor can take on more of the duties. This is especially important in such markets as Japan.

BMW isn’t entirely subtle about the the fact at the AH5 is a hybrid. The phrase “ActiveHybrid 5” is emblazoned in no less than five places throughout the car. Additionally the AH5 features the optional “Streamline” 18” wheels and the exclusive Bluewater metallic paint as an option. There’s also a mention in the trunk where the battery pack takes up some room.

The current F10 5 Series gets around corners very effectively but perhaps with a little less satisfaction than the previous generation 5. It would seem the steering is to blame as the car has enormous grip but a lack of connection to what’s really happening underfoot. And it’s a shame because the car is so exceptional for a large sedan when it comes to driving experience.

We pressed BMW on this and because we frankly want them to figure it out. Based on their response they may yet. But don’t expect electric steering systems to magically get all the feel back anytime soon. Nor should you expect them to go away. Not only are they better for efficiency (sensing a trend?) but they also better integrate with technologies such as lane departure warning systems.

Nevertheless the AH5 performs almost faultlessly around the corners and sweepers. We just wish it had a bit more soul behind it all.

And that leads directly to the question – should you consider the AH5 if you’re looking at a 5 Series? At $61,845 (including $895 destination and handling) it’s not priced badly by any means. In fact it’s almost a bargain considering the technology involved.

That said the real answer is rather complex. For someone who wants to combine efficiency with power there’s really no better combination in BMW’s line-up. It’s a brilliant system that has no downsides other than extra weight, cost and a bit of trunk missing. Performance is inline with what you’d expect and the characteristics of the car are all 5 Series.

So why would you not buy it? If you’re looking for a 5 Series that combines light weight, performance, simplicity and value for money, I’m not entirely sure the AH5 makes sense. At $62,845 it’s almost 8k more than the standard 535i and doesn’t bring a shocking difference in efficiency.

However for those looking to find that fine line between performance and effeciency the ActiveHybrid 5 Series is a pretty compelling choice. And the key reason is that it’s still a BMW. From the sound, feel and overall performance, the AH5 brings BMW’s core brand values to the world of hybrids. Not a bad thing as it’s a world that can use some new blood.

We’re just off the plane from having driven the new AH5 and will have our full review ready soon. But in the meantime you can get a first look at the car via BMWNA’s first official release.

Official release: BMW takes the development of intelligent hybrid drive systems to the next level with the introduction of the BMW ActiveHybrid 5 – another series-produced model in which a combustion engine and electric motor join forces to enhance both efficiency and the brand’s hallmark driving pleasure. The BMW ActiveHybrid 5 brings together a BMW TwinPower Turbo in-line 6-cylinder engine, an electric drive system and an 8-speed automatic gearbox for the first time. The latest generation of BMW ActiveHybrid technology also adds precisely controlled – and therefore extremely effective – intelligent energy management. All of which gives the BMW ActiveHybrid 5 an exceptional balance of performance and fuel efficiency for the benchmark performance sedan in the premium executive car class.

Its drive system generates combined output of 335 hp allows the car to be driven on electric power alone up to 37 mph (60 km/h) for 2.5 miles (4km), and accelerates the BMW ActiveHybrid 5 from 0 to 60 mph in 5.7 seconds (preliminary). The BMW ActiveHybrid 5 will arrive as a 2012 model in US showrooms, March 2012 with a base MSRP of $61,845 (including $895 destination and handling).

The 300 hp inline-6 with BMW TwinPower Turbo technology in the BMW ActiveHybrid 5 is the same engine well-known for its free-revving capability, pulling power and efficiency in the BMW 535i. The electric motor develops 54 hp and is supplied with energy by a high-performance lithium-ion battery housed in the trunk.

A harmonious blend of power from the two drive systems ensures that the 
BMW ActiveHybrid 5 boasts not only the sportiest performance in its market segment but also a significant improvement in efficiency). Its full-hybrid drive system enables driving on purely electric power which means emission-free driving in urban conditions.

In order to fully exploit the potential of the BMW ActiveHybrid technology, the power electronics in the BMW ActiveHybrid 5 uses a host of technologies to ensure the drive system runs at peak efficiency. The high-performance lithium-ion battery is recharged when the car is coasting or braking. The electric motor acts as a generator feeding energy into the high-voltage battery. By contrast, under acceleration, the electric motor takes on a boost function assisting the inline-6 by generating an extra burst of power, giving the sedan’s sporty driving character a noticeably sharper edge.

Integrated into the standard Driving Dynamics Control is an ECO PRO mode. It provides a relaxed and fuel-efficient driving style by tailoring the driving systems for maximum efficiency, including making more frequent use of all-electric mode. In ECO PRO mode, the combustion engine can be switched off and fully decoupled while coasting at speeds of up to 100 mph (160 km/h). This coasting mode combines comfortable driving with optimum utilization of the kinetic energy already generated. To avoid periods with the engine running at idle – at traffic lights or in stop-and-go traffic, for example – the BMW ActiveHybrid 5 is equipped with a hybrid start-stop function. Plus, the power electronics in the BMW ActiveHybrid 5 are linked up with the standard navigation system. This allows proactive analysis of driving conditions based on the selected route. This enables the drive components to be primed to deliver maximum efficiency (the effect may vary according to the quality of the available navigation data).

All the hybrid-specific components of the drive technology and energy management systems have been developed specially for use in the BMW ActiveHybrid 5. Both the electric motor and the air conditioning compressor are powered exclusively by the lithium-ion high-voltage battery, via the high-voltage electrical system. This allows a pleasant interior climate to be maintained even when the internal combustion engine is switched off – i.e. when the car is at a standstill, operating purely on electric power or in coasting mode. All of the new hybrid components are designed with durability to last the life of the vehicle.

Innovative combination: award-winning 6-cylinder inline engine, newly developed electric drive system.

The BMW ActiveHybrid 5 is the first hybrid model to use a BMW inline 6-cylinder engine in its powertrain. The BMW ActiveHybrid 7 and BMW ActiveHybrid X6 both utilize a V8 engine, which is combined with either one or two electric motors. The 3.0-liter inline-6, which develops 300 hp and peak torque of 300 lb-ft, has won both the International Engine of the Year Award and the Ward’s 10 Best Engines Award two years running. The BMW TwinPower Turbo technology in the inline-6 combines a twin-scroll turbocharger, High Precision Direct Injection, Double VANOS variable valve timing and VALVETRONIC intake control. This technology package improves throttle response, revving ability, refinement and efficiency, while an aluminum crankcase also optimizes weight.

The synchronous electric motor of the BMW ActiveHybrid 5 is integrated into the housing of the 8-speed automatic transmission, saving space. The interplay between the electric motor and gearbox is controlled by a clutch. The motor’s operating temperature is regulated by the combustion engine’s cooling system. The electric drive system develops 54 hp and makes 155 lb-ft of torque available from start. The motor is supplied with energy by a high-performance lithium-ion battery, specially developed for the BMW ActiveHybrid 5. The high-voltage battery is encased in special high-strength housing and positioned between the wheel arches in the trunk, providing it with optimum protection. It consists of 96 cells, has its own cooling system and offers usable energy capacity of 675 Wh.

The BMW ActiveHybrid 5 has both a conventional 14-volt power supply and a high-voltage supply with an operating voltage of 317 volts. They are linked by a voltage transformer which ensures that maximum electric energy can be used to enhance driving dynamics and comfort in any operating phase. Like the electric motor, the air conditioning compressor is also fed with power from the lithium-ion battery exclusively via the high-voltage supply. This ensures a pleasant interior climate, even when the combustion engine is switched off – i.e. when the car is at a standstill, operating purely on electric power or in coasting mode. In addition, the stationary climate control function can be used to cool the interior before the engine is started.

Electric motor: eager power delivery, compact design.

The BMW ActiveHybrid 5’s synchronous electric motor not only supports all-electric operations around town, it can also provide a performance-boost to the gas engine to deliver more powerful acceleration. In either case, the drive power is supplied instantly and without lag. Like all electric motors, it develops its full torque – of 155 lb-ft (210 Newton meters) – from a standing start.

Due to its high internal efficiency and low weight, the eight-speed automatic transmission contributes significantly to the efficiency of the powertrain. With its eight speeds, it combines a wide gear range with close ratio gear spacing. It also allows more use to be made of top gear, for a fuel-efficient, low-rpm driving style. The direct downshift capability and exceptionally short shift times can support very sporty driving. There is a controller throughout the high-performance transmission that ensures gear changes are always closely matched to the driver’s demands and the driving situation.

Intelligently controlled hybrid technology: unprecedented precision for maximum efficiency. To make the most of the ActiveHybrid technology in the BMW ActiveHybrid 5, the power electronics incorporate a range of innovative intelligent energy management functions whose aim is to ensure that the powertrain operates as efficiently as possible. The BMW ActiveHybrid 5 can operate in all-electric mode up to a speed of 37 mph (60 km/h), for zero emissions in town. The lithium-ion high-voltage battery can store s

Expert dialogue with Maximilian Ahme via M-Power.

Maximilian Ahme will answer the questions of MPW members. He is responsible for the technology of the entire vehicle with the exception of the electronics.

When did work begin on the development of the BMW M5 and how many kilometres were covered during testing?

Two to three years must be allowed for testing the development of a BMW M. In some cases predecessor vehicles are used in the first phase, enabling initial engine tests to be carried out, for example. However, this is just a short phase. The fine tuning then involves the latest models. The development departments for engine, electronics, chassis, etc. each have their own test vehicles to enable them to put the latest technology to the test. Approximately 2 million kilometres were covered throughout the world by the new BMW M5 in this way. How does the engine of the BMW M5 differ from that of the BMW X5 M/X6 M?

The engine of the BMW M5 has been almost completely redesigned. In essence, the only feature it has in common with the engine of the X5/6 M is the bank angle (90 degrees) and the cylinder spacing. The specification sheet also indicated a higher maximum rotational speed of 7,200 rpm.

A lot of new features have been added in order to cater for the demands for low fuel consumption and good response: starting from the continuous regulation of the variable valve timing (VALVETRONIC) by means of the optimised cross-bank manifold to the dethrottling on the intake and output side, where we use larger charge-air coolers and turbochargers with more air throughput according to the M-TwinScroll concept. This required a new cylinder head with new valve drive mechanism and high precision injection. VALVETRONIC is combined with direct injection with an eight-cylinder drive – BMW M has done some pioneering work here. This measure also saves fuel. The oil circulation system has been optimised: a wet sump with an additional oil pump, which has already proven itself in the previous engine. Engine and transmission control are also new. The overall package guarantees a responsiveness familiar from earlier M models with no sign of the so-called “turbo lag”.

Why wasn’t the automatic torque converter transmission adapted from the BMW X5 M/X6 M?

The new V8 engine in the M5 provides maximum performance between 5,750 and 7,000 rpm. In conjunction with the specially tailored M DKG dual-clutch transmission, we use the maximum engine speed of 7,200 rpm as we move up the gears in sporty driving style to ensure that we start off in each new gear with maximum output. This is precisely what we wanted to achieve by increasing the engine speed range. An automatic torque converter is not designed for the required speeds and could not be used for this reason. In addition, only the DKG dual-clutch transmission allows you to change gears without interrupting traction. This is very important for good acceleration times… There are no disadvantages in terms of fuel consumption as this is more dependent on overall transmission ratio rather than the number of gears. How do you get a turbocharged engine in a car to reach speeds of up to 7.200 rpm? Until recently this seemed impossible.

This isn’t so much a question of the speed of the engine or turbo-charger, after all we have already had speeds of up to approx. 14,000 rpm with the BMW Formula 1 engine. The characteristic zone of the charger in terms of pressure and volume has to be adjusted to the gas throughput of the engine. This in turn depends on the displacement, speed and required output characteristics. The principle is as follows: small chargers are good for fast responsiveness and high torque at low engine speeds, while large chargers are good for high maximum output. I think we have achieved the best possible compromise here with the new M5 in terms of responsiveness and power characteristics.

How does the cooling system work with 10 coolers?

With an output of 412kW / 560 HP, the new BMW M5 has power to spare and offers excellent driving performance. However, this enormous output creates the same level of combustion heat in all high-performance engines. In the case of the Formula 1 engine, the coolers are housed in an exposed position in the side boxes – a different solution needs to be found in the case of a sports limousine. For the new BMW M5 we have developed a tailor-made cooling package that covers all our requirements to perfection. A total of 10 coolers ensure that the temperature is kept just right, while also supporting the spontaneous response of the V8 engine.

The principle of direct or indirect charged air cooling applied to turbocharged engines. Air-to-air heat exchangers are used in the case of direct turbocharged cooling, which would have required much longer paths to the front of the car for the charged air with a lot of dead volume in our case. That’s why we use an air-water heat exchanger placed between the compressor and the intake manifold for every turbo charger. The heat generated while compressing the air is fed to three water-air coolers in the front of the car by means of the medium of water. The charge air thus takes the shortest path with a large diameter from the compressor via the charge air cooler directly to the intake channel. This improves the engine response. We have an air-water cooler and a total of three water-air heat exchangers for each cylinder bank: one radiator in the wheel arch to the left and right and one in front of the main heat exchanger. This means that a total of five coolers with their own reservoir and 2 electrically powered water pumps are used to cool the charge air.

In addition, there is the radiator for the main cooling circuit (high temperature circuit), familiar from every car. In the classic configuration, additional coolers are provided for the engine and gearbox oil and the steering hydraulics. Finally there is the condenser for the air-conditioning system. That makes ten coolers in all. The rear axle differential has an aluminium oil tray with cooling fins so that a separate radiator is not required there. A smaller offset in the differential reduces friction and therefore the build-up of heat. Less friction means less fuel consumption here too.

What role is played by the Efficient Dynamics measures in reducing ECE normal consumption by about 30%?

Such a reduction in consumption to 9.9 l/100 km in the ECE cycle is achieved through BMW EfficientDynamics measures and an improvement in efficiency. We have already explained how this works with the rear axle differential. In the case of the engine, the variable valve control and dual variable valve timing and the high torque at low engine speed make a significant contribution. On top of this comes the automatic engine start/stop, varioserve power steering pump, volume-regulated engine oil pump, roll-resistance-optimised tyres and brake energy recovery in order to charge the battery when coasting. The entire package helps in achieving consumption targets without compromising on driving pleasure. Another benefit: when consumption is taken together with the larger tank, the vehicle’s range is significantly increased.

Why is an all-wheel drive still not an option with the BMW M5?

In view of the performance and torque of the BMW M5, this might be considered an option. However, we believe any advantage is outweighed by the disadvantages of the all-wheel drive. More weight due to four driven wheels means higher fuel consumption and a shift in the axial load in the direction of the front axle. However, we are particularly concerned with a balanced distribution of weight for the driving performance typical of the M. We also had to position the engine higher, which would have led to a higher centre of gravity.

Why wasn’t the fuel tank volume increased to even more, e.g. to 90 litres?

We made the best possible use of the space under the rear seats. That’s why a steel tank is used instead of a plastic one. Steel allowed us to achieve the same rigidity with thinner walls and enabled us to increase the tank volume from 70 to 80 litres. We genuinely fought for every millimetre. After all, safety clearances also have to be met.

The press folder reads “innovative active M differential for optimising the transfer of power to the back wheels”. What is the innovation in the BMW M5?

The variable differential lock in the previous model is controlled by the speed differential between the drive wheels. In other words, this is a passive system in which the lock is activated by different wheel speeds. This is now achieved proactively by means of an electric motor with downstream transmission and ball ramp. We use a similar package of discs which is pre-stressed by means of the electric motor. The driver’s preferences are also taken into account, i.e. when the driver accelerates, the system starts to lock, even in response to fast-changing frictional conditions, e.g. on a “patchwork” of snow and asphalt. The system also operates when the car is coasting – the lock is activated when the wheel sensors detect the relevant values. This makes for greater driving stability. A passive system does not react in this case. While a passive system always operates with pre-stress, the active lock can be completely unlocked. One advantage of the reduced friction is the reduction in fuel consumption. When the M differential lock is active, we can still start off on mountain slopes even with a 25 percent incline and extremely variable frictional values (ice/asphalt). When you are on the slope, you find it hard to believe that you will be able to start, but is really does work. This is a better alternative than walking on the ice…

What is the role played by the tyres in determining the complex chassis regulation systems?

A large part of the car’s driving performance is determined by the tyres. The force transferred when the car is in a bend, or accelerating or braking passes through the tyres. The same is true of the response from the road. Chassis adjustment and steering are at least equally important. It takes tyres that are precisely tailored to the chassis to achieve the superior driving performance associated with the BMW M5. We develop our cars in close cooperation with the tyre manufacturers and for a particular tyre type. Tyres need to meet very stringent criteria, which is why it is not easy for tyre manufacturers to receive approval from us. I would therefore advise you only to use the tyres we approve.

Why was it decided to have two M Drive buttons?

Just one button only allows two adjustment options: the basic setup when starting and the personalised M Drive button configuration. This comprises the setting options for the engine and accelerator pedal characteristic curve, DSC, EDC, M DKG, Servotronic and Head-Up Display. The M5 is now always started in Efficient and Comfort mode, in other words the best setting for fuel consumption and comfort. One M button is now permanently set to Cruise mode, i.e. an automatic setting still applies, although the engine speeds increases and combustion has not yet reached its highest point in the chassis, so that I am still travelling at a reasonable speed. The second alternative is the sporty variant, where I shift gears myself (via the steering wheel paddles or using the gear stick), activating higher damper forces, giving me greater steering forces and making the engine respond even more aggressively. Many customers will probably be happy enough with these three setups. Everybody else will find it easy to adjust the assignment of the two M keys to their needs on the basis of the permanent basic setup.

How much more output is available in Efficient mode? How do the three modes differ?

There is no difference in terms of output, however the ratio of accelerator pedal position to power development varies. In “Efficient” the characteristic curve is flatter for a more gentle use of output, while is it much steeper in “Sport plus” for a very spontaneous and direct development of performance. Thus, unlike its predecessor, the BMW M5 always has full power available as and when you need it.

How has the chassis been altered in comparison with the BMW Series 5?

The front axle has a more rigid connection to the bodywork. In addition, the track has been widened, when meant that we had to move the wings further apart. We have broadened the support base of the front axle bracket, also reinforcing it with a shear panel – a metal plate screwed onto the front axle bracket at calculated points. This means that the forces are applied to the bodywork over a large area. This increases torsional rigidity, so that the body of the car is subject to even less distortion. In terms of kinematics, the rear axle follows the excellent principle applies in the predecessor model. However, the rear axle support is rigidly connected to the body, i.e. there are no rubber bearings. This results in greater driving precision and good responsiveness. A traction field is used following the same principle as on the front axle. On the rear axle we apply forces that affect the chassis, side skirts and transmission tunnel via a package of struts. In conjunction with the hydraulic rack-and-pinion steering with variable ratio, the drive receives very precise feedback regarding the road and the car’s reaction.

How high is the maximum lateral acceleration?

Depending on the road surface and ambient conditions, it can reach levels of up to 1.2 g with our standard tyres. This is not a constant value. Irregularities and unevenness on the road mean that short peaks of up to 1.3 g can be achieved, or perhaps even a little more on the Nürburgring circuit, for example, when the tracking force is briefly increased through compression. Thus, the 1.2 g simply relates to a so-called “standard curve”.

Which detailed solutions posed the greatest challenges?

The whole is more than sum of the parts. In view of the enormous performance, the coordination of the regulating systems is a particular challenge. In the final analysis, our customers and their families should be able to discover the versatility of the BMW M5 for themselves, whatever the weather. On the other hand, the BMW M5 should also shine on the race track. Reading the press reports, I’d say we have obviously succeeded.

BMW continues to research “highly automated” driving. This video shows how far they’ve come and what the future holds. How do you feel about the car’s electronics taking over under certain conditions? We’d love to hear in the comments section!

It’s the dawn of a new age at M. Or depending on how you look at it, a return to form (a la the M535i). Either way these new diesels touched by the magic of M look and sounds fantastic. Perhaps more importantly, the numbers look extraordinary; 381 hp and 546 lb-ft from a triple turbocharged inline six. Power is driven through an eight speed automatic gearbox and put down to the pavement via a revised xDrive system. The results as impressive as expected – 0-60 should fall somewhere in the mid four second range.

But all that aside, it’s the engine’s technology that has our mouths watering.

This is BMW’s first application of a triple turbo set-up and one of the first in the automotive industry. The size, arrangement and interplay of the turbos are designed to guarantee maximum power across the power range. The system comprises two smaller and one larger turbo. According to the driving situation, the low moment of inertia of the small turbochargers is exploited to the full to deliver razor-sharp responses, while the link-up with the large turbo is maximised to generate as much charge pressure as possible.

First came the rumor. Then came the official admission. Now comes the debut. Today BMW M takes the wraps off of its first products with diesel engines. No they aren’t M cars in the classic sense but they are a new breed of cars created by M to bridge the gap between full M products and “Series” cars.

However being that these first products are diesel, they will not be coming to the US. With diesel certification an extraordinarily pricey affair for the US market, projected sales don’t justify the investment. Forbidden fruit or not, the numbers look extraordinary; 381 hp and 546 lb-ft from a triple turbocharged inline six. Power is driven through an eight speed automatic gearbox and put down to the pavement via a revised xDrive system. The results as impressive as expected – 0-60 should fall somewhere in the mid four second range.

The premiere of the BMW M Performance Automobiles heralds the creation of a new category of car, one which marks out the sporting potential of the latest BMW models in particularly vivid style. Getting the ball rolling for the new breed are a quartet of inspirational models linked most significantly by a newly developed six-cylinder in-line diesel engine. Three turbochargers, maximum output reaching 280 kW/381 hp and peak torque of 740 Newton metros (546 lb-ft) provide a punchy introduction.

Without parallel worldwide, the new engine gives the BMW M550d xDrive Sedan, BMW M550d xDrive Touring, BMW X5 M50d and BMW X6 M50d performance figures head and shoulders above those of the diesel models currently topping their respective model series. The new M Performance TwinPower Turbo technology lays on a significant increase in output and torque across an extremely wide rev range. And yet despite this enhanced power delivery, fuel consumption and emissions figures in the EU test cycle are almost unchanged.

Unique engine, customary M set-up.

The further optimised combination of driving pleasure and efficiency provides fresh evidence of the outstanding development expertise on hand at BMW M GmbH in terms of powertrain technology. However, it is the typically harmonious interplay of powertrain, chassis technology and design that gives BMW M Performance Automobiles their innovative and distinctive character. An eight-speed Sports automatic gearbox and the intelligent all-wheel-drive system BMW xDrive – tuned to suit each individual model – team up with detailed modifications to chassis components and light-alloy wheels developed exclusively for the BMW M Performance Automobiles to deliver driving characteristics imbued with agility and precision. Precisely controllable handling properties reflect the expertise and experience of BMW M GmbH in the development of high-performance sports cars.

The familiar M style is also expressed through the cars’ bespoke body design, which takes its cues from the aerodynamic demands of driving at the dynamic limit. And the BMW M Performance Automobiles also boast an interior very much in keeping with the purposefully sporty driving experience.

Premiere: six-cylinder in-line diesel engine with three turbochargers.

The market launch of the first BMW M Performance Automobiles also sees the premiere of the most powerful diesel engine ever fitted in one of the brand’s models. The new unit shows BMW demonstrating its commitment to the development of ultra-sporty yet impressively efficient diesel powerplants. Globally unique technological highlights open the door to a new dimension in power development. The six-cylinder in-line engine developed for the BMW M Performance Automobiles uses its 2,993 cc displacement to generate maximum output of 280 kW/381 hp, giving the new diesel unit a specific output of 93.6 kW/127.3 hp per litre of displacement. No less imposing is the engine’s maximum torque of 740 Newton metres (546 lb-ft), all of which the driver will find on tap as low down as 2,000 rpm.

Playing a central role in this increase in power is M Performance TwinPower Turbo technology. For the first time, a BMW engine will feature three turbochargers. The size, arrangement and interplay strategy of the turbos are designed to guarantee maximum power delivery across a wide rev band. The system comprises two relatively small turbochargers and one large turbo, which join forces precisely to deliver the amount of power required. According to the driving situation, the low moment of inertia of the small turbochargers is exploited to the full to deliver razor-sharp responses, while the link-up with the large turbo is maximised to generate as much charge pressure as possible.

This innovative and globally unique multi-stage turbocharging concept represents a particularly efficient method of boosting output. In addition, the efficiency of the new diesel engine is further optimised by innovations including a new development stage in common-rail direct injection technology, featuring piezo injectors working with maximum pressure of 2,200 bar. The impressive quantity and quality of the technical innovations on hand complement the unrivalled development expertise of BMW in the development of diesel engines. The new powerplant strikes the most effective balance between output and fuel consumption of any series- produced unit of its kind.

The BMW M550d xDrive: a new benchmark in sporty driving pleasure and efficiency in the BMW 5 Series segment.

The unique properties of the new six-cylinder diesel engine play a key role in enabling the BMW M Performance Automobiles to redefine the relationship between driving pleasure and economy – and therefore ensure the BMW M550d xDrive and BMW M550d xDrive Touring act as extremely effective advertisements for BMW EfficientDynamics technology in the BMW 5 Series segment. These models embody a particularly high-level application of the principle of increased performance coupled with ultra-low fuel consumption and CO2 emissions. The typically M interpretation of the BMW 5 Series’ characteristics also allows drivers to experience the harmony of sporting capability and ride comfort, fascination and everyday usability in extraordinary depth.

Both the Sedan and Touring models prove more impressively than ever that the hallmark pulling power of a diesel engine can be converted into inspirational driving dynamics. The BMW M550d xDrive Sedan accelerates from 0 to 100 km/h (62 mph) in 4.7 seconds, while the BMW M550d xDrive Touring covers the same sprint in 4.9 seconds.

The two models showcase the efficiency benefits of diesel technology equally convincingly. In the EU test cycle the Sedan records fuel consumption of just 6.3 litres per 100 kilometres (44.8 mpg imp), the Touring 6.4 l/100 km (44.1 mpg imp). CO2 emissions are 165 grams per kilometre for the BMW M550d xDrive Sedan and 169 g/km for the BMW M550d xDrive Touring. Both models also meet the requirements specified by the EU6 exhaust standard.

Model-specific modifications governing power transfer, chassis and design enable a textbook M conversion of engine output into sporty driving pleasure. The standard-fitted eight-speed Sports automatic transmission comes with gearshift paddles on the steering wheel and is given model-specific settings, enabling even more rapid gear changes and helping the engine’s performance characteristics to be exploited to the greatest possible degree. Meanwhile, BMW xDrive improves the cars’ cornering dynamics, as well as enhancing traction and directional stability. The electronic all-wheel-drive system follows a control strategy tailored to each model. This allows the threat of understeer in extremely dynamic driving situations to be counteracted by adjustments to the power split, without the DSC

(Dynamic Stability Control) system linked up to xDrive having to intervene. Meanwhile, the air channelling properties, handling and appearance of both BMW M550d xDrive variants benefit from aerodynamically optimised body elements at the front and rear, Ferric Grey exterior mirrors and air intake bars, and exclusive 20-inch light-alloy wheels (available as an option).

The BMW X5 M50d and BMW X6 M50d: an imposing presence in both the acceleration and efficiency rankings.

Outstanding powertrain and chassis technology in combination with xDrive intelligent all-wheel drive allow the BMW X5 Sports Activity Vehicle and BMW X6 Sports Activity Coupe to display extraordinary poise and assurance. The BMW M Performance Automobiles based on the two BMW X models take these character traits to a whole new level. Thanks to the most powerful diesel engine in the BMW engine range, allied to the optimised power transfer, handling properties and aerodynamic balance for which M cars are renowned, the BMW X5 M50d and BMW X6 M50d set new standards in their respective classes in terms of sportiness, conceptual harmony and efficiency.

With its maximum output of 280 kW/381 hp and peak torque of 740 Newton metres (546 lb-ft) the engine developed for the BMW M Performance Automobiles also brings a level of performance to the two BMW X models which no other diesel-powered car in their segments can match. The BMW X5 M50d accelerates from 0 to 100 km/h (62 mph) in 5.4 seconds, the BMW X6 M50d in just 5.3 seconds, while average fuel consumption in the EU test cycle stands at 7.5 litres per 100 kilometres (37.7 mpg imp) for the Sports Activity Vehicle and 7.7 l/100 km (36.7 mpg imp) for the Sports Activity Coupé – only slightly above the figures for the existing diesel variants of the two models. CO2 emissions are 199 grams per kilometre for the BMW X5 M50d and 204 g/km for the BMW X6 M50d.

The eight-speed Sports automatic transmission with enhanced gearshift dynamics and the xDrive all-wheel-drive system – tuned to suit the individual model and emphasise the traditional rear-wheel set-up of BMW cars – transfer drive to the road with characteristic élan. Chassis technology which has likewise been modified using BMW M GmbH expertise ensures that the hallmark agility of BMW X models is geared even more intently to enhancing sporting capability. The BMW X5 M50d and BMW X6 M50d also underline their dynamic tendencies in the form of model-specific body features, which optimise both the supply of cooling air for the engine and the cars’ aerodynamic properties. 19-inch (BMW X6 M50d: 20-inch) M light-alloy wheels are also fitted as standard on these models. 20-inch light-alloy wheels in Ferric Grey developed exclusively for the BMW M Performance Automobiles can be specified as an option. Plus, Ferric Grey metallic exterior mirror caps and air intake bars – another distinguishing feature of BMW M Performance Automobiles – give the cars an even more individual visual appearance. BMW M Performance Automobiles: using outstanding expertise to increase driving pleasure – a tried-and-tested concept.

The development of high-performance sports cars with bespoke powertrain and chassis technology, stand-out design and interior features and model- specific cockpit controls and displays represents the core area of business of BMW M GmbH. The expertise required to fulfil this brief is rooted in decades of experience in the conception of racing cars, which initially constituted the sole focus of BMW Motorsport GmbH following the company’s founding in 1972. However, it was not long before this expertise was also being used to satisfy the demands of drivers with sporting pretensions for more power in their road cars. The first BMW 5 Series models were duly equipped with suitably modified powertrain and chassis technology in the mid-1970s.

In 1980 an additional BMW 5 Series model was unveiled for the first time; the BMW M535i boasted a significant increase in output (to 160 kW/218 hp) and modifications to the chassis, brakes, gearbox and rear differential. Also developed on the basis of the second-generation BMW 5 Series was the BMW M535i, which was on sale from 1984 to 1987 – alongside the BMW M5 following its 1985 launch. With its extra power moulded flawlessly into dynamic excellence and stand-alone stylistic identity headlined by aerodynamically optimised body components, the BMW M535i provided full-blooded driving pleasure yet also unhindered day-to-day usability. It marked the realisation of a concept whose success was rooted primarily in the harmony between powertrain, chassis and design achieved by BMW M GmbH, and which has now been revived in a fresh new form with the BMW M Performance Automobiles.

BMW M Automobiles Official Release

Over the past six months we’ve heard rumors of several “near” M cars that have been undergoing testing. Today we have our first official confirmation from M themselves. “The BMW M Performance Automobiles” will span the range from the X6 and 6 Series Gran coupe all the way down to the much rumored M135i. The idea is simple, bring near M levels of performance to cars with better every day drive-ability. Sounds a little like the E46 ZHP doesn’t it?

The first involved a tri-turbo diesel engine stuffed under the hood first in an X6 (the X6 M550d) and eventually in the 5 Series and the new 6 Series Gran Coupe. The engine, rumored to deliver 381 hp and 516 lb-ft., would be M’s first diesel product in their long storied history. And to us the real story with this car is the engine. BMW M has always been known as the master of petrol performance and has rarely ever (if ever) dabbled in diesel. Alpina, has produced and continues to produce some legendary diesel engines and of course Audi and Peugeot have had storied race careers with oil burners. M getting into the diesel business is big news, whether it ever leads to a pure M diesel or not.

But the plans don’t stop there. According to our sources BMW M is also working on a N55 powered 320 hp M135i. With suspension tweaked from the standard sport suspension, news wheels, steering and more power, the M135i will bridge the gap between the 135i and the now rather mythical 1M. But perhaps more importantly it’ll not be limited and will cost less than the previous baby M car.

So are these real M cars? Given what we’d know the answer is no. But that shouldn’t limit your excitement. This is M trying to bring it’s magic to cars that are more affordable, more efficient and easier every day drivers – while not sacrificing sacred badges like the M5 or M3.

We will have much more on this in the days and weeks ahead.

Official Release

In spring 2012, BMW M GmbH will unveil a new product range for drivers seeking a particularly sporty driving experience, yet who also value the familiar comfort and practicality of BMW models. The BMW M Performance Automobiles offer exclusive engine variants, noticeably enhanced agility and outstanding precision on the road, plus design laced with emotional appeal. The harmonious interplay of engine output, power transfer, chassis technology and aerodynamic balance provides a captivating showcase for the familiar M genes – in day-to-day driving and beyond. The BMW M Performance Automobiles will be presented to the global public for the first time at the International Geneva Motor Show 2012 which takes place from 8 – 18 March.

The BMW M Performance Automobiles represent a totally new model category none of its rivals can offer. Only the high-performance sports cars from BMW M GmbH provide a more convincing execution of an overall concept focused on inspirational driving dynamics. “We are targeting our efforts at customers looking for more emotionality and more performance, but who don’t want to forgo the everyday usability of their cars,” said Dr Friedrich Nitschke, President of BMW M GmbH. Nitschke announced plans for further additions to the new product line-up, referring to “a range including a wide variety of model series, as well as both petrol and diesel-engined variants”. The intelligent all-wheel-drive system BMW xDrive would also play a significant role in the BMW M Performance Automobiles, he added.

2011 will go down as one of the most successful years for BMW M GmbH since the company was founded. In addition to the BMW 1 Series M Coupe, which marked BMW M GmbH’s first ever foray into the premium compact segment, last year also saw the successful introduction of the new BMW M5. The imminent arrival of the BMW M Performance Automobiles provides 2012 – which will also feature the world premiere of the new BMW M6, among others – with an early highlight.

“The BMW M Performance Automobiles benefit from the full expertise of BMW M GmbH,” explained Nitschke. The BMW Group subsidiary can call on decades of motor sport experience when it comes to translating outstanding engine power into excellent dynamics. This development expertise also imbues the BMW M Performance Automobiles with their distinctive character.

The models in the new product category follow in the tyre tracks of the BMW M535i, which was unveiled in 1980 and went on to capture the hearts of performance-minded customers with its extra power, precisely tuned chassis technology and subtly modified design. A fresh addition to the BMW 5 Series ranks, the Sedan remained a highly successful member of the line-up through two model generations and – up to 1987 – with the BMW M5 for company within the range. “Our aim with the BMW M Performance Automobiles is to continue this tradition,” confirmed Nitschke.

Official Release: Detroit, MI – 9:00am EST January 9, 2012… On the occasion of the North American International Auto Show, BMW today announced the retail pricing of the new 2012 BMW ActiveHybrid 5.

The BMW ActiveHybrid 5 can operate in all-electric mode up to a speed of 37 mph (60 km/h), for zero emissions in town. The lithium-ion high-voltage battery can store sufficient energy to give an all-electric driving range of up to approximately 2.5 miles (4 km) at an average speed of 22 mph (35 km/h). Conversely, the powertrain system can combine the engine and electric motor torque to accelerate the BMW ActiveHybrid 5 from 0 to 60 mph in 5.7 seconds. The 2012 BMW ActiveHybrid 5 is scheduled to arrive in US BMW Centers in late Spring 2012.

From the American big three to the Germans and Japanese, each company from those respective nations is said to be showing something that will come to market within the next year.

BMW i3 and i8 Concepts

The BMW i3 Concept and the BMW i8 Concept, with their highly innovative and efficient drive systems, demonstrate how future mobility can be both sustainable and dynamic. While the BMW i3 Concept is an all-electric vehicle and therefore optimally equipped for operation around town, the plug-in hybrid BMW i8 Concept combines its electric motor with an internal combustion engine to deliver a high level of performance.

All-electric – the BMW i3 Concept.

The electric motor of the BMW i3 Concept is designed primarily for operation in an urban environment, developing 170 hp, with peak torque of 184 lb-ft. Typically of an electric motor, maximum torque is developed from standstill, in contrast to an internal combustion engine where torque increases with engine rpm. This makes the BMW i3 Concept highly agile and provides impressive acceleration. The BMW i3 Concept accomplishes 0-37 mph in under four seconds and 0-60 mph in under eight seconds.

Best of both worlds – the BMW i8 Concept.

The i8 Concept combines the advantages of two different drive systems. As a plug-in hybrid it reaps the benefits of an electric motor and an internal combustion engine for maximum efficiency with maximum dynamics. At the front axle is the electric motor adopted from the BMW i3 Concept and modified for use in the BMW i8 Concept’s hybrid power train, while a 220 hp turbocharged three-cylinder petrol engine developing up to 221 lb-ft of torque drives the rear axle. Together, the two drive units take the vehicle to a governed top speed of 155 mph. Like the electric motor, the 1.5-litre three-cylinder petrol engine was developed entirely in-house by the BMW Group and represents the latest state of the art in conventional engine design. Acceleration of 0 to 60 mph in under five seconds combined with fuel consumption in the European cycle of under three litres per 100 kilometres (approx. 84 mpg) are figures currently beyond the capability of any vehicle powered by a combustion engine of comparable performance. Depending on charging habits and the nature of the route, it is even possible to improve on these figures.

After years of avoiding it, BMW is making the Tokyo Motor Show all about alternative power plants for 2011. Making it’s official production debut will be the AciveHybrid 5 Series.

Official Release: The introduction of groundbreaking drive system innovations sees BMW taking driving pleasure to consistently greater heights, while at the same time reducing fuel consumption and emissions to ever lower levels. At the Tokyo Motor Show 2011 (3 – 11 December 2011) the German premium carmaker is underlining its pace-setting development expertise in this field with the presentation of next-generation BMW ActiveHybrid technology, new four-cylinder petrol engines with BMW TwinPower Turbo technology and – for the first time in the Japanese market – a six-cylinder in-line diesel engine with BMW BluePerformance technology. This year’s Tokyo Show is hosting the world premiere of the new BMW ActiveHybrid 5. The full-hybrid Sedan brings together a six-cylinder in-line petrol engine, an electric drive system, an eight-speed automatic gearbox and a high-performance lithium-ion battery. This package of technology allows the brand’s third hybrid model to be driven on purely electric power around town, offers drivers a boost function delivering extremely dynamic acceleration, and enables the car to coast with the combustion engine switched off. The BMW ActiveHybrid 5 also comes with a globally unique intelligent energy management system, which works in tandem with the navigation system to prepare the car’s drive functions in advance for upcoming road conditions.

Members of the new generation of four-cylinder petrol engines with BMW TwinPower Turbo technology see action not only under the bonnet of the new BMW 1 Series, but also in the BMW X1 xDrive20i. And BMW TwinPower Turbo engines also provide the heartbeat of the new BMW 6 Series Coupé. Here again, the result is driving pleasure taken to another new level and efficiency without parallel in this market segment.

Advanced Diesel technology, including BMW BluePerformance, gives BMW another string to its bow when it comes to drastically reducing emissions on the road. Indeed, Japan is now preparing to welcome its first diesel BMW. The BMW X5 xDrive35d BluePerformance combines a sporty, commanding appearance with the imposing pulling power and exemplary emissions of its 3.0-litre six-cylinder in-line engine. In addition to a diesel particulate filter and oxidation catalytic converter, its exhaust treatment package also features an AdBlue system with urea injection to reduce NOx levels in the car’s exhaust. All of which allows BMW BluePerformance technology to make its exhaust emissions as clean as possible and therefore satisfy the world’s most stringent exhaust standards.

Today BMW takes the wraps off of its latest hybrid, the ActiveHybrid 5 Series. In contrast to the X6 and even 7 Series hybrids, BMW expects this car to sell in noticeable numbers and has given it the tech to make it more palatable to the car buying public. Additionally (if sources are to believed) the power-plant will also form the the basis of the upcoming 3 Series ActiveHybrid.

Official Release: BMW today announced the introduction of its newest hybrid, the BMW ActiveHybrid 5. Based on the BMW 535i Sedan, the ActiveHybrid 5 brings together BMW’s 3.0-liter TwinPower Turbo inline six-cylinder engine, an electric drive system and an eight-speed automatic transmission for the first time. The latest generation of BMW ActiveHybrid technology also adds precisely controlled energy management to the mix. All of which gives the BMW ActiveHybrid 5 an exceptional balance of performance and fuel economy for a benchmark performance/luxury sedan. Its drive system generates combined output of 335 hp (DIN), allows the car to be driven on electric power alone up to 37 mph (60 km/h), and accelerates the BMW ActiveHybrid 5 from 0 to 60 mph in 5.7 seconds (preliminary). The BMW ActiveHybrid 5 will arrive in US showrooms in March 2012.

The 300 hp inline six with BMW TwinPower Turbo technology in the BMW ActiveHybrid 5 is the same engine renowned for its free-revving capability, pulling power and efficiency in the BMW 535i. The electric motor develops 55 hp and is supplied with energy by a high-performance lithium-ion battery housed in the trunk.

A harmonious blend of power from the two drive systems ensures that the BMW ActiveHybrid 5 boasts not only the sportiest performance in its market segment but also a double-digit percentage improvement in fuel economy over the BMW 535i based on preliminary results. Its full-hybrid drive system enables driving on purely electric power which means emission-free driving in urban conditions.

In order to fully exploit the potential of the BMW ActiveHybrid technology, the power electronics in the BMW ActiveHybrid 5 use a host of technologies to ensure the drive system runs at peak efficiency. The high-performance lithium-ion battery is charged when the car is coasting or braking. The electric motor acts as a generator feeding energy into the high-voltage battery. By contrast, under acceleration the electric motor takes on a boost function. Here, it assists the inline six by generating an extra burst of power, lending the sedan’s sporty driving character a noticeably sharper edge.

Integrated into the standard Driving Dynamics Control is an ECO PRO mode. It provides a relaxed and fuel-efficient driving style by tailoring the driving systems for maximum efficiency, including making more frequent use of all-electric mode. In ECO PRO mode, the combustion engine can be switched off and fully decoupled while coasting at speeds of up to 100 mph (160 km/h). This coasting mode combines comfortable driving with optimum utilisation of the kinetic energy already generated. To avoid periods with the engine running at idle – at traffic lights or in stop-and-go traffic, for example – the BMW ActiveHybrid 5 is equipped with a hybrid start-stop function. Plus, the power electronics in the BMW ActiveHybrid 5 are linked up with the standard navigation system. This allows proactive analysis of driving conditions based on the selected route. This enables the drive components to be primed to deliver maximum efficiency (the effect may vary according to the quality of the available navigation data). All the hybrid-specific components of the drive technology and energy management systems have been developed specially for use in the BMW ActiveHybrid 5.

Innovative combination: award-winning six-cylinder in-line engine, newly developed electric drive system. This is the first time that a BMW inline six has been mated to a BMW ActiveHybrid system. The 3.0-liter engine, which develops 300 hp and peak torque of 300 lb-ft, has won the international Engine of the Year Award two years running. The BMW TwinPower Turbo technology of the six-cylinder engine combines a twin-scroll turbocharger, High Precision Direct Injection, Double VANOS variable valve timing and VALVETRONIC intake control.

The synchronous electric motor of the BMW ActiveHybrid 5 is integrated into the housing of the eight-speed automatic transmission, saving space. The interplay between the electric motor and gearbox is controlled by a clutch. The motor’s operating temperature is regulated by the combustion engine’s cooling system. The electric drive system develops 55 hp and makes 155 lb-ft of torque available from rest. The motor is supplied with energy by a high-performance lithium-ion battery, specially developed for the BMW ActiveHybrid 5. The high-voltage battery is encased in a special high-strength housing and positioned between the wheel arches in the trunk, providing it with optimum protection. It consists of 96 cells, has its own cooling system and offers usable energy capacity of 675 Wh.

The BMW ActiveHybrid 5 has both a conventional 14-volt power supply and a high-voltage supply with an operating voltage of 317 volts. They are linked by a voltage transformer which ensures that maximum electric energy can be used to enhance driving dynamics and comfort in any operating phase. Like the electric motor, the air conditioning compressor is also fed with power from the lithium-ion battery exclusively via the high-voltage supply. This ensures a pleasant interior climate, even when the combustion engine is switched off – i.e. when the car is at a standstill, operating purely on electric power or in coasting mode. In addition, the stationary climate control function can be used to cool the interior before the engine is started.

Intelligently controlled hybrid technology: unprecedented precision for maximum efficiency. The BMW ActiveHybrid 5 can operate in all-electric mode up to a speed of 37 mph (60 km/h), for zero emissions in town. The lithium-ion high-voltage battery can store sufficient energy to give an all-electric driving range of up to approximately 2.5 miles (4 km) at an average speed of 22 mph (35 km/h).

The internal combustion engine is only started when the driver requires more power: it is then engaged automatically. The electric motor provides a “boost” function to supplement the engine when accelerating. Maximum combined power is 335 hp (DIN), with maximum torque of 330 lb-ft. Under combined internal combustion/electric power, the BMW ActiveHybrid 5 delivers a 0 to 60 mph in 5.7 seconds (preliminary).

Hybrid-specific Auto Start-Stop function and coasting mode. The specially designed Hybrid Auto Start-Stop function provides seamless operation when the vehicle is stopped in traffic – after the internal combustion engine is shut-off, the automatic climate control continues to run off the lithium-ion battery. When the driver releases the brake, the vehicle will restart on either the electric motor alone or the electric motor and the inline six, depending on the high-voltage battery’s current charge level and on how much power the driver wants.

Another innovation being pioneered in the BMW ActiveHybrid 5 is the coasting mode. It further improves efficiency by shutting the internal combustion engine down not only when the vehicle is stationary, or when driving in town, but also while coasting at higher speeds. In the BMW ActiveHybrid 5, this coasting mode is available at any speed up to 100 mph (160 km/h). Coasting mode switches off the internal combustion engine and disconnects it from the drive shaft. From this point on, the BMW ActiveHybrid 5 continues moving soundlessly, with zero emissions and with no engine braking effect. In coasting mode, as with all-electric mode for urban driving, all safety and comfort functions remain fully operational.

Intelligent energy management reads the road ahead.

The advanced power electronics coordinate the operation of the internal combustion engine and electric motor proactively based on the selected driving route for even more efficient energy management in the BMW ActiveHybrid 5. The power electronics are integrated with the standard navigation system, which means they can access and analyze data indicating changes in certain road conditions based on the route ahead, or driver requirements. From this analysis, all powertrain systems and the on-board electronics are managed appropriately so that energy can be used as needed or stored in preparation for what is coming up in order to make the most efficient possible use of the available energy.

Factors that may cause a change in powertrain operating strategy include the topography of the route and speed limits. For example, if the selected route indicates that a hilly stretch is coming up soon, the BMW ActiveHybrid 5 can invest all the high-voltage battery’s electrical energy in providing supplementary driving power for the up-hill without concern about depleting the battery, knowing that the battery will be recharged “at no cost” during the subsequent descent. On longer downhill sections the electric motor’s generator function can be enlisted to recharge the high-voltage battery with no loss of speed. The operating strategy can also be managed so as to ensure that the high-voltage battery is as fully charged as possible when nearing the end of the journey, thereby increasing the potential electric driving range in anticipation of lower driving speeds.

The operating status of the powertrain components is shown in displays, unique to the ActiveHybrid 5, in the instrument cluster and in the Control Display. As well as the energy flow and energy recuperation display, these include an additional gauge next to the tachometer which shows the boost effect being provided by the electric motor during acceleration. A display in the iDrive interface provides a variety of information – for example on the battery’s current charge level and the power-sharing between the internal combustion engine and the electric motor during the course of a journey.

State-of-the-art hybrid technology, typical BMW 5 Series: highest standards of driving dynamics, safety and comfort. The chassis specifications of the BMW ActiveHybrid 5 are pure BMW 5 Series. They include double-wishbone front and integral rear suspensions, Servotronic speed-sensitive power steering, a high-performance brake system and 18-inch alloy wheels. Dynamic Damper Control, featuring electronically controlled shock absorbers, is available as an option. The Dynamic Stability Control system, which stabilizes the vehicle by individually applying the brakes and reducing engine power, also incorporates functions such as Dynamic Traction Control, the Anti-lock Braking System, Cornering Brake Control, Dynamic Brake Control, Brake Assist, Brake Fade Compensation, Brake Drying and Start-Off Assistant.

The hybrid-specific safety features, which protect the high-voltage lithium-ion battery and the power electronics, are integrated into the BMW 5 Series’ existing active and passive safety systems. In a collision, high-strength structural components and large deformation zones help to keep impact forces away from the passenger cell and also from the hybrid drive components. Other standard safety systems on the BMW ActiveHybrid 5 include front and side airbags, side curtain head airbags for front and rear passengers, three-point inertia-reel belts on all seats, belt force limiters and belt latch tensioners on the front seats and ISOFIX child seat attachments in the rear. BMW Assist includes enhanced Automatic Collision Notification. In the event of a collision severe enough to cause an airbag to deploy, eACN immediately calls the emergency call center from the car’s embedded phone. It not only transmits the car’s location but also an assessment of the risk of severe injury to the people inside, based on a ground-breaking injury assessment algorithm. This assessment is provided to first responders before they even arrive at the scene.

In the BMW ActiveHybrid 5 the standard Driving Dynamics Control switch offers not only Sport+, Sport and Comfort set-ups (as well as Comfort+ mode if the optional Dynamic Damper Control is specified), but also the ECO PRO mode. As an alternative to the standard 8-speed automatic transmission, an 8-speed sport automatic with faster shift times is available.

A number of BMW ConnectedDrive features are available for the BMW ActiveHybrid 5 including Park Distance Control, a rear-view camera, Surround View, High-Beam Assistant, Parking Assistant, Active Blind Spot Detection, Lane Departure Warning, BMW Night Vision with pedestrian recognition and Head-Up Display. Innovative technologies also allow in-car integration of smartphones and music players. The BMW Apps option offers unprecedented integration of the Apple iPhone.

To further enhance comfort and individuality, the standard 4-zone automatic climate control and Navigation System can be supplemented by options such as active seats, front ventilated seats, Comfort Access, the Smart Opener for the trunk, and high-end audio and rear entertainment systems.

BMW ActiveHybrid 5: The only hybrid that is also a BMW 5 Series The BMW ActiveHybrid 5 features newly developed hybrid components that are combined with a BMW TwinPower Turbo inline six for the first time, and innovative functions for improved efficiency as well as driving enjoyment. At the same time it broaches yet another market segment, taking BMW’s hybrid development work another step forward.

The BMW ActiveHybrid 5 arrives at US BMW centers in March 2012.

We’ve just returned from the Frankfurt IAA and to say that the BMW Hall is overwhelming is an absolute understatement. The scale of BMW’s home auto show venue is immense. Imagine an auto show floor stateside and then think that the size of that entire building is around the size of BMW’s own in Frankfurt- it is that enormous. BMW didn’t disappoint its fans in its presentation of its newest offerings and future concepts; offering a wide range of vehicles, all presented in the ideals of Efficient Dynamics. Our cameras were able to capture it all so be sure to check out the gallery.

World premieres of the BMW i3 Concept and BMW i8 Concept, new F20 BMW 1 Series (including new Efficient Dynamics Edition), new F10 ///M5, 520d Efficient Dynamics Edition, 1 Series with M Sport Kit (March 2012 launch), an electric scooter, Husqvarna motorcycle and several other models. Namely the BMW Performance 1 Series Design Studie, X1 Efficient Dynamics Edition and 3 Series Edition models that we not featured during the actual Media Conference.

We were puzzled by BMW’s decision to feature the 6 Series coupe’ and convertible so extensively during the media conference as these two models (although with new 40d power) were not discussed in the press releases leading up to the event. Secondly, the 6ers have been extensively covered by the media with other power plants. If anything, we were expecting a new model such as the 6 Series GranCoupe to be the surprise guest but rumors circulating the show were that BMW decided at the 11th hour the 6 Gran Coupe didn’t fit the theme of efficiency they were going for. Reportedly, it will be shown in Geneva closer to market launch. In case you were wondering; yes, even the ///M5 was discussed in terms of improved efficiency if you can imagine that.

There was another object on our scavenger hunt list that we searched high and low for in the vast BMW hall; the X6 ///M wearing M Performance stripes- it was nowhere to be found. Maybe that was for the better as our lenses were needed to capture the rest of the show.

We hope you enjoy the photos and we’d like to send a big thank you to Michael Talley for contributing his to our gallery. We’ll have more coverage from other manufacturers so stay tuned!

FULL GALLERY HERE

We are LIVE at the Frankfurt IAA. Over the next few days we will be bringing you photos and stories from Germany’s largest auto show.

The 640d was the opening act, and set the tone for a series of debuts with more power and greater efficiency.

BMW also showed two new Efficient Dynamics models, 116d and 520d that tout hybrid like efficiency numbers.

The ///M5 made its public debut to a packed house. It simply looks fantastic in Monte Carlo blue.

BMWi continues to wow with its use of high tech materials and gadgetry. The i8 is featuring Laser Headlights which are brighter and more efficient than even the most modern LED systems.

It was an eventful morning and is sure to continue.

BMW has been testing automated driving vehicles for some time. A few weeks ago we even got a test “ride” in an automated 3 Series around Laguna Seca. To call the experience bizarre would be an understatement. Now they are taking to the streets and testing in real world applications.

Official Release: Motorway A9 from Munich to Nuremberg – and as usual – there is a high volume of traffic. But despite the stress of the situation, the driver sits calm and relaxed behind the wheel. Why? Because the car is highly automated, i.e. it brakes, accelerates and passes other vehicles on its own, while also monitoring and adapting to the prevailing traffic conditions. And the second reason why? Because Dr. Nico Kämpchen, Project Manager of Highly Automated Driving at BMW Group Research and Technology, has already completed nearly 5,000 test kilometres with his team. In order to offer drivers comfortable and safe vehicles in the future, equipped with the most modern assistance systems available, the engineers at BMW Group Research and Technology have been working for many years on the development of electronic co-pilots to support automated driving in specific situations – for example the BMW TrackTrainer tested on the race track, as well as adaptive cruise control (ACC) and the Emergency Stop Assistant. To further understand the potential offered by these systems, as well as their limitations, researchers are ready to take their next major step: developing advanced driver assistance systems for the motorway.

To accomplish this, researchers have equipped a BMW 5 Saloon with intelligent software as well as vision assistance and environment detection systems. The advanced automated assistance function for motorway journeys can be activated with the push of a button. From this point on, the prototype system can autonomously control acceleration and braking, and it can safely pass slower vehicles. One of the greatest challenges early in the project involved reacting to vehicles merging on to the motorway at exit and access points – but even this problem could be solved with a cooperative approach. The prototype system reacts to the situation by allowing the merging vehicles to join the traffic flow, and it can even change lanes giving the merging vehicles adequate space to enter traffic safely. This is possible up to a speed of 130 km/h, but in compliance with current traffic regulations regarding speed limits and such things as prohibited passing zones.

“This is an entirely new situation and experience for the driver – it is a strange feeling handing over complete control of the car to an autonomous system. But after a few minutes of experiencing the smooth, sovereign and safe driving style, drivers and passengers begin to relax somewhat and trust the independent system,” says Nico Kämpchen, Project Manager for Highly Automated Driving at BMW Group Research and Technology.“ Nevertheless, the driver is still responsible for the situation at all times and must constantly keep an eye on traffic and the surroundings.”

To ensure that the automated research vehicle functions smoothly and with agility in real traffic, the car must be endowed with strategies to react appropriately in daily traffic situations. The basis for these strategies is comprised of two parts: first, pinpointing the position of the vehicle in its own lane is essential and second, the car must be able to clearly recognize all vehicles and objects in its nearest surroundings. This is accomplished through the redundant fusion of various sensor technologies such as lidar, radar, ultra sound and video cameras that monitor the environment around the automobile. Redundant does not mean “superfluous” – to ensure that the vehicle situation is precisely assessed, at least two different measurement methods must be used in every direction. In this way the developers at BMW Group Research and Technology can be sure that a potential weakness in one method is counterbalanced by the strength of the other method.

By accessing digital maps, the camera and the localisation data of the extremely precise GPS, the automated vehicle prototype can determine its location in its own lane, and it also receives exact information about the characteristics of the route ahead, including the number of lanes that section of the motorway has. This information is supplemented by data from the forward-looking camera integrated in the lane departure warning system. Objects in front of the vehicle are detected by the radar sensors of the adaptive cruise control system with Stop&Go function and by a laser scanner as well. The same is true for objects at the sides or rear of the vehicle.

Precursors and basis – the BMW TrackTrainer and the Emergency Stop Assistant.

The groundbreaking technology needed for automated driving assistance systems was developed by engineers at BMW Research and Technology in two pioneering projects that brought forth the BMW TrackTrainer and the Emergency Stop Assistant. The BMW TrackTrainer supports autonomous driving on competition race courses. With the precision of the localisation a safe and yet very dynamic driving style can be realised. The TrackTrainer is currently used in BMW driver training sessions to give participants a genuine feel for the racing line – they experience it behind the wheel and not from the passenger seat. With merged data from an exact digital map, along with GPS and video data, the TrackTrainer can autonomously guide a vehicle along the racing line of a complete race track for training purposes. The system is already in the second generation, featuring optimised and precise position localisation achieved by merging redundant sensors. The constant comparison of GPS and video data with the digital maps and internal vehicle data was used to automatically guide a vehicle around the legendary North Loop of the Nürburgring on 21 October 2009. Then on 25 May 2011, the BMW TrackTrainer performed a similar feat at the Laguna Seca Raceway in California, demonstrating that fast and dynamic automated driving is indeed possible.

“The main difference between the sessions at the rack track and trials on the motorway is that we are not alone when driving along a public motorway. That is why we were interested in learning about the developments in the Emergency Stop Assistant Project to ensure safety in our own undertaking,” explains Nico Kämpchen.

The emergency stop assistant prototype realized by BMW is yet another milestone in the development of automated functions for assisted driving. The system is part of the SmartSenior Initiative of the Federal Ministry of Education and Research in Germany which was launched in May 2009. The system incorporates innovative technologies for controlling and pinpointing the location of a motor vehicle and analysing the vehicle environment for added safety. If a driver loses control of a vehicle – for example due to a health emergency – the emergency stop assistant can detect the situation and autonomously take control of the car and bring it to a safe stop. The system activates the emergency flashers, carefully monitors traffic and guides the vehicle to the right shoulder of the road. Then an emergency call is automatically sent out to inform authorities of the situation, including information for emergency medical teams to ensure a quick and efficient response. This is all based on the Advanced Emergency Call function from BMW ConnectedDrive that is already available as a feature for production automobiles. This project served as the foundation for the environment recognition function that is used in automated motorway driving.

Automated future scenarios– Parking Assistant and Traffic Jam Assistant from BMW ConnectedDrive in the BMW i3 Concept.

Research will continue on automated vehicles equipped with advanced driver assistance systems in order to develop innovative assistance functions for the future. Examples are the Parking Assistant and Traffic Jam Assistant in the BMW i3 Concept. Since the BMW i3 Concept is primarily designed as an urban vehicle, it is equipped with functions that make parking easier and driving in congested traffic less stressful. The park assistant automatically parks the vehicle without any driver intervention. The car accelerates and brakes on its own, and shifts gears from forward to reverse as needed when difficult parking manoeuvres are required. The Traffic Jam Assistant helps drivers in rather monotonous traffic situations and congested areas, taking over so that the vehicle can “go with the flow” and the driver can relax. It maintains a safe distance between vehicles and automatically controls the speed and steering, and is able to stop the car if necessary. As long as the driver keeps one hand on the steering wheel, the vehicle can provide assistance in keeping the car precisely in its lane at speeds up to 40 km.

Automated driving on motorways provides important information and experience that is essential in developing technologies that assist in keeping vehicles safely on track, and this information will influence future strategies for advanced driver assistance.

“The next thing we want to ‘teach’ our prototype is how to deal with road construction sites and motorway junctions. Construction sites are a big challenge because they take on all kinds of forms, which makes detection, localisation and determining the right vehicle response quite difficult.” Nico Kämpchen and his team have plenty of work to do and are looking forward to finding solutions to these challenges as well.

Official Release: Driving pleasure, premium quality and reliability guarantee the latest models from the BMW and MINI brands the highest acclaim in international automobile markets. That has been confirmed yet again in a recent study conducted by international market research firm J.D. Power. In its latest customer survey – the Automotive Performance and Layout Study (APEAL) – assessing satisfaction levels among North American new car buyers, the BMW 5 Series range, BMW X3, BMW Z4 and MINI Countryman emerged as winners of their respective vehicle segments. In addition, four more models from the BMW Group finished in the top three of their category. This tally means the BMW Group boasts the highest number of segment winners of all manufacturers in the latest APEAL survey.

Such excellent individual scores also boosted the overall rankings of the BMW and MINI brands, with BMW coming third in the latest survey. As well as the class-winners – the BMW 5 Series range, BMW X3 and BMW Z4 – the outstanding results of the BMW 7 Series range also contributed to this outcome. The luxury saloon not only came second in its segment but also claimed the second-highest individual score of all the vehicles involved in the APEAL survey, making it the top European model in the entire competition. The BMW 3 Series range and the BMW X6 also finished as runners-up in their respective segments.

The MINI brand likewise bumped up its overall results compared to the previous year. The main driving force here was the new MINI Countryman, which instantly took top honours in its vehicle class. The MINI Cooper also made it onto the winners’ podium, finishing second in its segment.

J.D. Power and Associates ranks among the world’s leading market research firms. Through its numerous surveys, the renowned institute regularly evaluates satisfaction levels among vehicle buyers in the main international car markets. The results of the latest APEAL study for North America are based on a customer survey carried out by J.D. Power on average three months after initial vehicle registration.

We’re back after a month break that saw Michael make the big move across the pond to Germany. But the news never stops and, as you’d expect, we have a ton to catch-up on. Full list of topics after the break.

• 1M CSL Rumor (squashed)
• M2; what to expect
• X1 M and X3 M
• Z4M Coming?
• M5 Engine details
• Valencia Orange F20 1 Series?
• 6 Series Gran Coupe boring?
• 5GT M Sport (is it a punch-line?)
• M1 rumors
• N20 and Start/Stop on the US
• F32 M3 Tri-turbo engine

And more.

The 5 Series will be the next BMW in the US to receive the new N20 four cylinder engine. BMWNA announced today that the 528i will be moving from it’s 3.0L inline six to a 2.0L four cylinder with the same 240 hp rating but even more torque (up 20 at 260 ft lbs). The 528i will also be the first ‘series’ BMW to receive BMW’s clever start/stop system that automatically cuts the engine at stoplights. Furthermore the 528i will have what BMW is calling ECO PRO which adjusts the engine map, heating, air conditioning, and mirror/seat heating to minimize fuel consumption.

All told it’s a great upgrade to one of BMW’s bread and butter products. The 528i has been the most popular 5 Series in the US line-up. With these changes we can’t help but expect the gap to widen further.

Look for many of these features to find their way in the new F30 model line-up that will debut later this fall.

Official Release: BMW today announced significant enhancements for the 2012 BMW 528i Sedan, most significantly BMW’s new TwinPower Turbo 2.0-liter four-cylinder engine. To further enhance its efficiency in everyday driving, the 2012 BMW 528i also receives auto start/stop technology. For those who face the realities of four-season driving, the 2012 528i becomes the newest member of the 5 Series family in the US to offer BMW xDrive all-wheel drive as an option. When the 2012 model arrives in BMW showrooms this fall the most popular model in the 5 Series line-up is destined to become even more so.

BMW TwinPower 2.0-liter Four-Cylinder

Like the company’s latest TwinPower Turbo 3.0-liter turbo inline-6, the new 2.0-liter engine will combine high-pressure direct-injection and BMW’s VALVETRONIC intake control (hence the name: TwinPower) with a forced induction system consisting of a single twin-scroll turbocharger. With 240 horsepower and 260 lb-ft of torque, it offers more power and torque than the normally aspirated 3.0-liter inline-6 featured in the 2011 BMW 528i.

The maximum output of 240 horsepower is achieved at 5,000 rpm, 1,500 rpm lower than in the normally-aspirated 3.0-liter inline six. The peak torque of 260 lb-ft, comes on stream at just 1,250 rpm. Not only is that 30% more torque than the aforementioned inline-6, it also peaks 1,500 rpm earlier. The vigorous power comes on early and climbs steadily all the way to redline.

The 4-cylinder engine with its all-aluminum crankcase is lighter and more compact than a 6-cylinder engine of equivalent power. The turbocharger is a twin-scroll system. The exhaust streams leaving the two pairs of cylinders are kept completely separate as they flow through the exhaust manifold and the turbocharger, taking a spiral path to the turbine wheel. This configuration results in very low exhaust back pressure at low engine rpm, and allows the energy of the exhaust gas pulses to be optimally managed and translated into powerful rotation of the turbine blades, without a delay in throttle response.

The patented BMW VALVETRONIC system with seamlessly variable intake valve lift control dispenses with the throttle valve system typical of conventional engines. Instead, combustion air mass is controlled inside the engine, resulting in much faster response. Pumping losses are kept to a minimum, making the engine more efficient.

The High Precision Injection direct-injection system also helps to improve efficiency. Centrally positioned between the valves, solenoid injectors with a maximum injection pressure of 200 bar (2,900 psi) precisely control the supply of fuel. The fuel is injected very close to the spark plug, resulting in clean and homogeneous combustion.

The cooling effect of the injected fuel also allows for a higher compression ratio than might otherwise be possible. This results in further efficiency improvements. In the 2012 528i this innovative new engine will again be mated to BMW’s newest 8-speed automatic transmission. The 2012 528i accelerates from 0 – 60 mph in 6.2 seconds, 0.4 seconds quicker than the 2011 model and will deliver up 15 percent better fuel efficiency (final EPA results are pending).

xDrive All-Wheel Available for the 2012 528i

Like other 5 Series models, xDrive intelligent all-wheel drive has been updated to match the performance and character of the 528i. BMW xDrive provides the reassurance of sure-footed traction in all weather and road conditions, but it also goes far beyond that to provide an added measure of active safety. BMW’s Integrated Chassis Management (ICM) is able to identify and limit understeer by shifting torque rearward (initially 80% to the rear axle) while preserving the stability for which xDrive has been so widely recognized. As a second step, ICM can then apply a precise combination of throttle and individual rear-corner braking in order to maintain neutral handling in a corner – regardless of road surface conditions.

Every BMW xDrive model receives standard Hill Descent Control. This selectable function allows the driver to descend slopes in extremely slippery conditions while maintaining control at a pre-set speed.

Extra Measure of Efficiency with Engine Auto Start/Stop

In addition to BMW EfficientDynamics technologies like Brake Energy Regeneration, the 2012 BMW 528i will feature Engine Auto Start/Stop. This feature switches off the engine when the car is stationary at traffic lights or in slow-moving traffic in order to minimize idling. An ECO PRO mode, which is activated by the driving experience switch, adjusts the engine map, heating, air conditioning, and mirror/seat heating to minimize fuel consumption. The resulting increase in range is shown on a display.

The 2012 528i is the very embodiment of BMW EfficientDynamics – more powerful, more efficient and more sure-footed. The 2012 BMW 528i arrives at US BMW centers beginning this fall.

What you see above could almost be called revelation. M’s latest M5 is getting back to basics with an almost fully exposed engine under it’s hood. And while it’s not the entire engine, BMW is showing off a good percentage of the M5′s mill for the first time since the E34 M5. In fact it’s been 15 years since we’ve been able to actually see any details of the M5′s engine at all. But why is this?

BMW has a history of shrouding some of the best engines in the world with copious amounts of black meaningless plastic. Whether it’s in the name of design, marketing or simply sound-proofing we here at BF have long disapproved. And there’s no better example of this than the last two generations of the M5.
