2008 BMW M6
The new BMW M6 concept made its debut at the 2005 Geneva Motor Show. It is based on the BMW E63/E64 6-Series, introduced in 2004. It shares the same 5.0 L V10 S85 engine and SMG III gearbox with the E60 M5, and produces 507 hp (373 kW) / 384 ft·lbf (521 Nm).
BMW claims it accelerates from 0 to 100 km/h (62 mph) in 4.6 seconds (0-60 mph: 4.1 s [Road & Track [2/06]) and has an electronically limited top speed of 250 km/h (155 mph). With the limiter removed, the top speed can reach 330 km/h (205 mph).
The carbon fiber and other light materials are used in places like the bumpers and roof that are far from the centre of gravity and/or high up, so that they not only reduce the overall weight but improve the handling by reducing, respectively, the moment of inertia and the centre of mass height.
