The BMW M6 is a high-performance version of the 6 Series marketed under the BMW M sub-brand from 1983 to 2019 (with a hiatus from 1990 to 2004).
Introduced in the coupe body style, the M6 was also built in convertible and fastback sedan ('Gran Coupe') body styles for later generations. An M6 model was built for each of the first three generations of the 6 Series.[1] Production of the M6 ended in 2019 and it was replaced by the BMW M8 in 2019.[2]
E24 M635CSi/M6 (1983–1989)
The M6 lineage began in 1983 with the M635CSi model of the E24 6 Series range, which was powered by the M88/3 DOHC straight-six engine (which was a modified version of the engine used in the BMW M1). In most countries, the model was badged the M635CSi, however the equivalent model in North America and Japan was simply badged as "M6".[3]
