BMW'S M DIESELS: THE OFFICIAL DETAILS
5-series, X6 and X5 tri-turbo M cars to be first offerings of M Performance sub-brand
BMW has finally revealed the full details of its forthcoming range of diesel M cars, the first to come under the new 'M Performance Automobiles' banner and the first to get BMW's new extra-torquey tri-turbo diesel engines.
All the diesel Ms will get the same version of the new treble-turbo Twinpower 3.0-litre straight-six diesel, an M-developed powerplant that effortlessly outpunches any previous diesel efforts from Bee-Em.
The key stats you'll need to remember for pub-talk ammo are 381hp, 545lb ft of torque (between 2,000 and 3,000rpm). Which is pretty impressive - and even more so when you consider that the 5-series version emits just 165g/km of CO2, the same as the 535d, but with almost 70hp more to offer.
The diesel side of things, meanwhile, combines with BMW's now familiar Efficient Dynamics gubbins (stop-start, brake energy regeneration, etc) to provide impressive fuel economy figures. BMW claims 37.7mpg on the combined cycle for the X5, with the X6 managing 36.7mpg. The 5-series manages 44.7mpg in saloon form and 44.1mpg in estate shape.
Talking of xDrive, we understand that the M550d will only be available as the four-wheel-drive M550d xDrive model. Since BMW won't sell a 4wd 5-series in the UK, that means it'll be for left-hook continetal Europeans only.
Inside, bespoke stainless steel sill plates, leather-bound dashboards and M steering wheels and seats smarten up the ambience, while mild exterior styling tweaks set the cars apart from ordinary BMWs.
