Power will come from the same 552bhp 4.4-litre twin-turbo V8 that powers the M5 and M6, and should be able to match the Coupe’s 0-62mph time of 4.3 seconds. Top speed will be limited to 155mph but an optional M Driver’s Package should increase this to around 190mph.
With a wheelbase that’s 113mm longer than the standard M6, the Gran Coupe will certainly be more family friendly thanks to the more spacious rear seats. And, unlike the two-door, you’ll be able to fold the rear seats down to increase boot space to 1,265 litres.
BMW hasn’t announced prices yet, but with the M6 Coupe starting from £93,820 it seems likely to carry a price-tag of around £96,000.
