BMW 6 Series

Overall verdict


Excellent diesel engine, good to live with


A better car in 4dr Gran Coupe form, M6 is disappointing
The BMW 6-Series is a luxurious, huge Coupe that, thankfully, now looks good again. But it's no sports coupe

What we say:

What is it?

BMW’s enormous GT that’s best seen as a continent crosser rather than the dynamic sports car many expect. Don’t bother with the petrol engines and choose the peachy diesel: yes, it’s preferable even to the mighty M6, which somehow misses the target.

Last year’s facelift saw the grille widened and the bumpers reshaped among other things. Truth be told, the differences aren’t huge (as you’ve probably noticed)


The outside world is a remote place in the new Six coupe. Gone are any sensations of speed or intimacy with the road. Capable of careering down the autobahn at 155mph, and it’ll corner at obscene speeds, but you always feel like you’re sitting in a plush hotel bed holding a steering wheel.

Inside, fit and finish are on a par with Audi, and because its such a good cruiser, it’s actually comfortable to live with, unlike its swaggering, brash predecessor.

You get a choice of a 640d, a 650i twin-turbo V8 with 450bhp and the 640i turbocharged straight-six, packing 320bhp. Ruddy impressive, that last one - 0-62mph takes 5.3 seconds and it’ll top out at, surprise surprise, 155mph - but it’s not adorable. It lack the electrifying noise of old-school unblown BMW sixes. The diesel is a better fit for the 6’s continent-crushing persona. 

On the inside

It’s a big GT, and its huge inside. There’s a decent-sized boot at 460 litres, but because it’s so low and so wide, its probably not the easiest thing to park in a tight space.


The 640i claims 37.2mpg and the 650i 32.1mpg, which actually isn’t too bad. But predictably the 640d manages a much better 52.3mpg while emitting 143g/km of CO2; not bad when you consider it’ll still hit 62mph in 5.3 seconds.

How about something completely different?

If it really is a sports car you're after, save a bundle and go for an M235i instead
