2013 M6 Coupe unveiled at the 2012 Geneva Auto Show

M Division BMWs make their mark on the performance segment — hands down, but often at the expense of style, some would argue.

Arguments be damned, BMW is doing its best to alleviate that concern with the 2013 M6 coupe, unveiled today at the 2012 Geneva Auto Show.

The long-bodied M coupe offers a sleek, flat design where an M3 or M5 would feel considerably more stout. Despite that sleek styling, the M6 coupe is still an agressive performance machine capable of running from 0 to 100 kmh (62 mph) in 4.2 seconds.

It achieves that time with the same high-revving 4.4-liter V8 as the M5, but with 20 extra horsepower for a total 560 hp.

Despite its considerable grunt, the car is actually supposed to be 30 percent more fuel efficient than its predecessor thanks to a 7-speed dual-clutch transmission, though those numbers are based on the European test cycle which is often unreliable.

Perhaps the most attractive feature is the optional 20-inch M wheels that come with the optional M carbon ceramic brakes and massive 15.6-inch rotors (larger than some cars wheels).

Governing those wheels, an active differential constantly adjusts the power distribution between the rear wheels to ensure maximum power delivery.
