History of used BMW M6
The history of the BMW M series began in 1984 when the first model, the M635CSi was released. The car was a high-performance version of the popular BMW E24 coupe and featured a modified engine, brakes, and suspension. In 1986, the next generation M88/13 engine was introduced in the M635CSi, and in 1988, the BMW M71 engine was added to the lineup.
In 1989, a new model called the E24 M635CSi came out and it featured an upgraded version of the six-cylinder S38B36 engine which had 325 horsepower (240 kW). It also included redesigned front and rear spoilers and 17" alloy wheels with uprated suspension and braking systems.
In 1990, the BMW M-Technic was introduced which featured an upgraded interior that had more supportive seats with better side bolstering. This model also included a multi-link rear axle with coil springs instead of traditional shock absorbers. The E24 M635CSi was produced for one year in 1991 before it was replaced by the E63/E64 BMW M635CSi.
The second-generation M Coupé, the E63/E64 BMW M635CSi was introduced in 2003 and it was available as a coupé or convertible. It featured a V-shaped engine hood, wide wheel arches, an aggressive front bumper, and 19" alloy wheels. The car was powered by a naturally aspirated, high-revving V-12 engine that produced 500 horsepower (373 kW).
In 2006, the BMW M Coupé was replaced by the E63/E64 BMW M635i which featured a twin-turbocharged inline six-cylinder engine with Valvetronic. This engine produced 315 horsepower (235 kW) and was available with either a six-speed manual or automatic transmission.
The third-generation M Coupé, the F06/F12/F13 BMW M635CSi was introduced in 2012 and it is currently still in production.
