The Gran Coupé has been given to M, fettled with a new engine, revised suspension, bigger brakes, loads more equipment and a thumping big V8 with BMW's TwinPower turbocharging to give it 560hp. A heady cocktail indeed, particularly given the Gran Coupé's fine looks. This M version gives you even more reason to go all weak at the knees with its M specific styling and quad exhausts burbling away around the back.
Exterior
Already a bit of a looker the BMW Gran Coupé's appeal only increases with M division's makeover. A deeper front bumper with large openings manages airflow and feeds cooling air to the M6's big V8, while larger 20-inch light alloy wheels are specified - behind which sit bigger M specific brakes. A new rear apron, within which BMW M division's signature quad tailpipes are situated, also features, but the single biggest change over its non-M Gran Coupé brethren is the fitting of a carbon-fibre reinforced plastic roof.
Interior
The interior gets a smattering of the motorsport-derived carbon weave, while deeper, more supportive sports seats with integrated belt guides, plentiful M badging, Alcantara roof lining with a split level recess and leather trim throughout set it apart.
Mechanicals
Sharing its 4.4-litre TwinPower Turbo V8 engine with its M5 and M6 relations, the M6 Gran Coupé's output is 560hp, while maximum torque of 680Nm developed between 1,500- and 5,750rpm. That V8 drives the rear wheels via a seven-speed M Double Clutch Transmission and the Active M Differential. As with all M's product there's ample opportunity to fiddle with the car's make up via the variable damper settings, M Servotronic steering modes and shift programs on the automatic gearbox. Two M buttons allow owners to pre-program preferred settings and access them quickly via a single push.
Anything else?
We could make a list, but suffice to say the standard equipment is extensive, and there's an opportunity to tick a few boxes to add to the list price if you desire. One such option includes the Driver's Package, which raises the electronic speed limiter from 250- to 305km/h, though the 0-100km/h time stays pegged at 4.2 seconds - comfortably quicker than the M5. There's stop-start for economy, the official combined figure of 28.5mpg (9.9 litres/100km) pretty remarkable given the performance. You'll not get anywhere near it in reality, though. Prices? They've yet to be confirmed. But, if you have to ask...
