BMW will be adding the 3.0 litre twin-turbo diesel engine to both the 6-series coupe and convertible. This new 6 will carry the same engine as the 335d, which will arrive in 2007. The 635d will be equipped with a 286HP six-cylinder engine, and will enable the coupé to reach 100km/h from rest in around 6 seconds, all the way to an electronically controlled limited topspeed of 250km/h.
But why would BMW even think of equipping a 6-series with a diesel engine? Why would buyers, that are after luxurious sporting coupes, go for an economic diesel engine? Probably BMW sees a hole in the market with the new 635d. Further, the release of the new diesel 6 will coincide with the launch of a new 163hp diesel version of the 3-series convertible; the 320cd.
BMW’s 3.0 litre diesel is one of the best engines of its kind in the world; it won the international engine of the year award in it's class. Still many purists agree that a diesel engine does not belong in a coupe. However, given the performance numbers, who really cares what kind of fuel goes in your car?
