Yes that is right, a 6 series with a sequential turbo diesel! We have no idea if or when this car will tour the streets of the US. It is just interesting to read the rave reviews this engine is receiving.

The shear fact that even in a larger car it is still able to reel in 34 mpg (when converted from imperial gallons) and have excellent performance is astonishing. We look forward to BMW finally allowing the US to have the engine much of the world has already been enjoying!

A new breed of GT – Dave Jenkins

| A Week at the Wheel | Cambs, England | BMW 635d |

Engine & Transmission:

BMW ‘s existing engine line-up was hardly lacking in terms of quality – each of the petrol units in the line-up are gems in their own rights. The addition of a diesel model to the 6 Series range was something we had mused about in the past, but until the introduction of this engine BMW probably lacked the courage to push oil burners into this market sector. However, with the introduction of the increasingly common 3.0-litre, six-cylinder, sequentially twin-turbocharged engine there was little risk of falling short of market expectations.

In actual fact the engine, combined with the latest automatic gearbox, adds more attributes to the 6 Series ‘ list of talents and accentuates many of those already present. The effortless muscularity of the diesel matches the punch of the big petrol engines and the long legged nature actually adds to the refinement, the tacho registering little more than 2,000rpm at motorway speeds with nothing but a murmur reaching the cabin. In addition to this the obvious benefits of economy figures pushing towards the 40mpg mark makes the 635d the sensible choice of powertrain for all but the most ardent petrol fan or power nut.


It didn ‘t take the mind of a rocket scientist to come up with this combination of GT and the world ‘s best diesel engine, but BMW ‘s courage to bring it to the market place is admirable; it raises the 6 Series ‘ game to a new level. One can ‘t help feeling that the competition will follow: a turbodiesel Jaguar XK is a mouth-watering possibility, but for now the BMW 635d enjoys a free reign as something of a pioneer in its class.
