Pictures and details of the four-door 552bhp BMW M6 Gran Coupe following its debut at Detroit

The BMW M6 Gran Coupe has been unveiled at the Detroit Motor Show.

The 552bhp performance four-seater is the latest addition to BMW’s growing M Division range, and is the first four-door model to wear the M6 badge. It comes complete with the same snarling 4.4-litre twin-turbo V8 and double-clutch transmission as the latest BMW M5.

The M6 Gran Coupe weighs in at 1,950kg, just 5kg more than the M5. However, like the two-door M6, the Gran Coupe sprints from 0-62mph in 4.2 seconds – a tenth faster than the M5, and two tenths quicker than its most obvious rival, the Mercedes CLS 63 AMG.

Top speed for the BMW M6 Gran Coupe is limited to 155mph. However, buyers will be able to opt for a performance package which raises the limiter to 189mph and adds some uprated tyres to cope with the extra high speed potential.

Based on the 6 Series Gran Coupe, the new car has a unique M bodykit, which includes an aggressive front spoiler, flared wheelarches, side skirts and four exhaust pipes in the rear diffuser. It also has 20-inch alloys, a lowered ride height and a weight-saving carbon-fibre roof.

Dynamic dampers are fitted as standard, as is an M button with a host of steering and throttle settings. Ceramic brakes, however, are an optional extra.

The interior comes with leather upholstery and rear climate control. Boot space is 1,265 litres.

The Gran Coupe should be the best-selling M6 in the UK, with prices expected to start from £98,500 when it arrives in 2013. That’s £25,000 more than the similarly powered M5 saloon.
