BMW to Release New & Updated Diesels at Frankfurt IAA

As part of BMW ‘s latest press release on the Frankfurt IAA, the company has released some information a series of new and/or updated diesel engines. And within that, there ‘s one new engine that will quietly be making it ‘s debut in the form the four cylinder 525d. The 5 series equipped wit this new 2-litre all aluminum diesel powerplant pumps out 218 hp & 332 ft lbs of torque. BWM ‘s conservative estimates show it hitting 0-62 in only 7 seconds while getting an astonishing 4.8 to 5.0 litres / 100 km (the updated 535d with an engine we ‘re more familiar with gets 5.4 – 5.6). It ‘s such an impressive middle ground that we believe this could be the new diesel engine destined for the US market within the next several years.

We ‘ll have more on the Frankfurt IAA next week and from the show floor.

Official Release: New diesel engines for the BMW 5 Series: increased pulling power and efficiency thanks to BMW TwinPower Turbo technology. From the autumn of 2011, the BMW 525d will feature a new four-cylinder diesel engine with BMW TwinPower Turbo technology. The 2-litre, all- aluminium power unit is equipped with multi-stage turbocharging according

to the Variable Twin Turbo principle and Common Rail direct injection with piezo injectors. Thanks to the variable turbine geometry of the small turbocharger, it is characterised by exceptionally responsive behaviour and a lower weight. The small turbocharger becomes active at low engine speeds and the degree of effectiveness of the large turbocharger adapts precisely to each load requirement.

Compared with its predecessor, maximum power output of the new BMW 525d has increased by 10 kW to 160 kW/218 hp, which is available at 4 400 rpm. Maximum torque of 450 Nm is now available between 1 500 and 2 500 rpm. The thereby achieved increase in agility and pulling power is evident in further improved acceleration from 0 to 100 km/h, which is now 7 seconds for the sedan and 7.2 seconds for the touring. Top speed of the new BMW 525d Sedan is 243 km/h (automatic: 239 km/h), the new BMW 525d Touring reaching 236 km/h (automatic: 233 km/h). With an average fuel consumption of 5.0 to 5.3 litres/100 km (automatic: 4.8 to 5.0 litres) for the sedan and 5.3 to 5.5 litres/100 km (automatic: 5.1 to 5.4 litres) for the touring model, average fuel consumption is up to 20 percent lower than that of the predecessors. The respective CO2 emission levels are 132 to 138 grams/km (automatic: 126 to 132 grams) for the sedan and 138 to 145 grams (automatic: 135 to 142 grams) for the touring (figures according to the EU test cycle, depending on selected tyre format).

Extensive modifications have increased performance of the 3-litre engine in the new BMW 530d by 10 kW to 190 kW/258 hp, which is available at 4 000 rpm. Maximum torque of the power unit featuring a turbocharging system with variable turbine geometry and Common Rail injection with solenoid injectors, is 540 Nm (in conjunction with automatic transmission: 560 Nm) available between 1 500 and 3 000 rpm.

As a result, the BMW 530d Sedan now accomplishes acceleration from 0 to 100 km/h in a mere 6.1 seconds (automatic: 6.0 seconds). The BMW 530d Touring requires 6.2 seconds (automatic: 6.1 seconds). The sedan’s top speed is electronically limited to 250 km/h, the touring reaching 247 km/h (automatic: 248 km/h). Compared with the predecessor models, average fuel consumption is around 13 percent lower. It is now 5.7 to 5.9 litres/100 km (automatic: 5.3 to 5.5 litres) for the sedan and 5.9 to 6.2 litres/100 km (automatic: 5.5 to 5.8 litres) for the touring model. CO2 emissions are 149 to

155 grams/km (automatic: 139 to 145 grams) for the BMW 530d Sedan and 155 to 162 grams/km (automatic: 145 to 152 grams) for the BMW 530d Touring (figures according to the EU test cycle, depending on selected tyre format).

The new version of the 3-litre power unit in the BMW 535d features a modified multi-stage turbocharging system operating according to the Variable Twin Turbo principle and Common Rail injection with piezo injectors. As a result, it delivers a maximum power output of 230 kW/313 hp at 4 400 rpm with maximum torque of 630 Nm being available between 1 500 and 2 500 rpm. The immense pulling power allows the BMW 535d, which is equipped as standard with an eight-speed automatic transmission, to accelerate from 0 to 100 km/h in 5.5 seconds, whereby the sedan and the touring models both boast the same figures. Top speed of each variant is limited to 250 km/h. Equally as impressive is the average fuel consumption of 5.4 to 5.6 litres/100 km (touring: 5.6 to 5.9 litres) and a CO2 emission level of 142 to 148 grams/km (148 to 155 grams) (figures according to the EU test cycle, depending on selected tyre format).

    What I’m really looking forward to is the 3.0L tri-turbo that is expected to power the 50d models.

    Sounds like good news. Hopefully these will both jump the pond.
