The BMW ///M6, also known as the BMW M635CSi, is a high-performance version of the 6-Series automobile, designed by the motorsport division of BMW. The BMW M6 was produced from 1983 to 1989, and then 2005 to 2010. Third generation was introduced on February 12th, 2012 via internet press release.

This 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 373 kW (500 hp) / 520 N·m (380 lb·ft).

BMW claims it accelerates from 0–62 mph (0–100 km/h) in 4.4 seconds. Road & Track measured the 0–97 km/h (0–60 mph) time as 4.1 seconds. The top speed is 312 kilometres per hour (194 mph) but it is limited to 249 km/h (155 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; 405 PS), but engaging the M button allows the full 373 kW (507 PS; 500 hp). It weighs 1,710 kg (3,770 lb) Road & Track (Feb 2006) compared to the 1,660 kg (3,650 lb) E92 BMW M3 Road & Track (Dec 2007) thanks to a carbon fibre reinforced plastic roof panel as well as thermoplastic front wings, aluminum doors and bonnet and compound boot lid.

The carbon fibre and other light materials are used in places like the bumpers and roof that are far from the center of gravity and/or high up, so that they not only reduce the overall weight but improve the handling by reducing the moment of inertia and lowering the center of mass height.


It was offered as both a coupe and a cabriolet. 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 of about 4.1 seconds (4.6 convertible)(Road and Track, March 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.

In the 2010 model year, the M6 was the second-most expensive BMW sold in the U.S. after the 760Li ($137,000), with anMSRP of $108,150 for the convertible and $102,350 for the coupe. In the U.S. the M6 had one of the largest residual value drops at 19%, as it had little if any changes since its 2006 introduction.

Production of the M6 ended in mid 2010, with sales over the five year run totalling 9,087 for the coupe and 5,056 for the convertible.
