The images show that the Gran Coupé will wear the same subtly aggressive body kit as the M6 coupé and convertible. The four-door coupé is due to go on sale in the middle of next year and will rival the Mercedes-Benz CLS63 AMG and Audi S7.
The Gran Coupé will use the same 552bhp 4.4-litre twin-turbo V8 found in the M5 and M6 coupé. Performance figures should comprise a 0-62mph time of 4.3sec and an electronically limited top speed of 155mph.
Prices have yet to be announced but are expected to start at just under £100,000.
