BMW M6

BMW claims it accelerates from 0 to 100 km/h (62 mph) in 4.4 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 M6 has the same 'power button' as the M5 which modifies the throttle response. From ignition, the car delivers 399 bhp (298 kW), but engaging the button allows the full 373 kW (507 PS; 500 hp). It weighs 3,770 lb (1,710 kg) thanks to a carbon fibre reinforced plastic roof panel as well as thermoplastic front wings, aluminum doors and bonnet (hood) and compound boot (trunk) lid.

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 center of mass height.

It is currently available as a coupe and a convertible. A lightweight CSL version of the M6 was expected to be released in the near future, however, BMW has since officially stated that no such version of the M6 will be built, as there is currently no market for such a model. The 2007 coupe is expected to have a 0-60 mph time in about 4.3 seconds (4.8 convertible)(Road and Track, September 2006). Both the M6 coupe and convertible can be visually distinguished from the 630i, 645Ci and 650i by their deeper front valance with air intakes, more contoured side sills, aerodynamic side view mirrors, an additional rear valance with diffuser and the absence of front fog lights.
