• M Division’s four-door coupe unveiled
• 552bhp and 501ft/lb of torque from its twin-turbo V8
• On sale in May next year

The BMW M6 Gran Coupe has been unveiled. Munich’s first attempt at a four-door coupe, the six-series Gran Coupe, has been given the ‘M’ treatment and features the engine from the M6 Coupe and the M5 saloon as well as a raft of chassis modifications.

BMW has given the M6 Gran Coupe a more muscular look, with a deeper front bumper and larger air intakes, as well as chromed ‘kidney’ grilles dominating the front. Around the side, it gets extended side skirts as well as the addition of ‘M’ side vents behind the front wheel arches. At the rear, again the bumper is deeper than on the standard Gran Coupe and benefits from a diffuser and quad exhaust pipes. To help lower the centre of gravity and to reduce weight, the M6 Gran Coupe gets ‘M’ Gmbh’s signature carbon fibre re-enforced plastic roof panel.

Inside, the car gets M Sport front seats and the whole interior is trimmed in Merino leather. ‘M’ decals also feature prominently in the interior. The rear seats split 60:40 and with them folded down, the boot’s capacity increases from 460 litres to 1,265.

Under the bonnet, the M6 Gran Coupe gets the 552bhp twin-turbocharged 4.4-litre V8 which has already been seen in the M5 saloon and the M6 coupe and convertible models. This engine puts out 501ft/lb of torque as well, which launches the car from rest to 62mph in 4.2 seconds and on to an electronically limited 155mph top speed. Despite the car’s volcanic performance, the engine still manages to achieve 28.8 mpg on the combined cycle, while emissions have been limited to just 232g/km of CO2. Power is sent to the rear wheels by a seven-speed M-DCT dual-clutch transmission.

M Division is famous for its chassis wizardry and its engineers have waved their wands over this car as well. It gains the active M Differential found in other ‘M’ cars which splits the torque between the two driven wheels to aid traction, variable dampers and hydraulic, variable ratio power steering. It is also possible to change the ferocity of the gear changes.

Standard equipment on the car includes 20-inch light-alloy wheels, leather, heated front seats as well as automatically dimming wing and rear-view mirrors, a multimedia infotainment system and climate control. Also as standard comes head-up display, parking sensors. An extensive options list includes a rear-view camera, automatically-dipping headlights, lane change warning, lane departure warning as well as BMW Night Vision. It will also be possible to integrate your smartphone into the infotainment system and use the internet while driving.

The M6 Gran Coupe will go on sale in May next year, with prices starting at £97,490.
