BMW has finally revealed the production version of its new 6-series Gran Coupe, the CLS and A7-rivalling four-door that's set to hit Blighty in July 2012.
BMW has three engines available from launch - a 640i with a turbocharged 3.0-litre straight six with 320hp and 332lb ft of torque, the 650i with a 450hp, 479lb ft turbocharged 4.4-litre V8, and the 640d, with a twin-turbo 3.0-litre diesel that produces 315hp and 464lb ft.
And although the 650i is fairly rapid, with a 0-62mph sprint dealt with in 4.6secs, it's the 640d that's surely going to grab most attention, hitting 62mph from rest in 5.4secs and yet managing a combined fuel economy figure (and yes, we appreciate that's not the same as a real-world figure) of 50.4mpg.
And yes, a 560hp M6 version is on the way for the end of 2012 (woohoo!).
Up to the trailing edge of the A-pillar, the Gran Coupe is identical to the 6-series cabrio, but it gets a longer and flatter roof, substantial B-pillars (and a pair of rear doors that, like the front two are frameless).
Inside, BMW has used the extra length and height to provide seating for four adults. The rear bench also offers up a third three-point belt, a layout BMW cutely calls 'four plus one'.
The car will get its official public unveiling at Geneva in March, and is expected to cost around £2k more than its two-door equivalent.
