Template:Short description Template:Infobox automobile
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.<ref>Template:Cite web</ref> Production of the M6 ended in 2019 and it was replaced by the BMW M8 (F91/F92/F93) in 2019.<ref>Template:Cite web</ref>

E24 M635CSi/M6 (1983–1989)Template:Anchor
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".<ref>Template:Cite web</ref>
The European-specification M635CSi used the M88/3 engine (without a catalytic converter), which produced Template:Convert at 6,500 rpm and Template:Convert at 4,500 rpm.<ref name="M6 JPN">Template:Cite web</ref> The M6 version, sold in North America and Japan, used the S38B35 engine (with catalytic converter), which produced Template:Convert and Template:Convert at the same engine speeds.<ref>Template:Cite web</ref> The catalyzed engine was also used in European and other market cars beginning in the summer of 1987, with identical specifications to the federalized engine.<ref name="AR88">Template:Citation</ref> The sole transmission for all models was a 5-speed Getrag 280 manual transmission.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
Other changes included BBS RS wheels, a rear lip spoiler, a larger front air dam, larger front brakes and revised suspension with a Template:Convert lower ride height.<ref>Template:Cite web</ref>
The E24 series became a "world car" for the 1988 and 1989 model years, sporting the same bumpers and aerodynamic treatments as its high-performance counterparts across all markets.
According to BMW, the car can accelerate from Template:Convert in 5.8 and 6.8 seconds for the European and North American versions respectively. The curb weights of the 1987 models are Template:Convert for the M635 CSi and Template:Convert for the M6.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> A top speed of Template:Convert<ref name="AR87">Template:Cite book</ref> made the European M635CSi the second fastest BMW automobile ever built at the time, next to the M1. The quarter mile time for the M635 CSi has been recorded at 14.5 seconds while Template:Convert is achieved in 15 seconds.
A total of 5,855 cars were produced.<ref>Template:Cite web</ref> Of these, 1,677 cars were imported to North America.<ref name="bmwmregistry E24">Template:Cite web</ref> Due to the elongated front and rear bumpers, the length of the U.S. models is Template:Convert.
Production of the E24 M635CSi/M6 ended in 1989. Template:Clear right

This results in a 0 to Template:Convert acceleration time of 3.9 seconds for the coupe and Gran Coupe versions.<ref>Template:Cite web</ref>
In 2016, the Competition Pack engine was upgraded to Template:Convert and Template:Convert of torque, resulting in a 0 to Template:Convert acceleration time of 3.8 seconds for the coupe and Gran Coupe versions.<ref>Template:Cite web</ref>Template:Clear right

M6 GT3

Around the start of 2015, BMW Motorsport began developing a replacement for the successful BMW Z4 GT3 which already had been in action since 2010, where they selected the M6 as the base model. Throughout the year, the factory engineered the M6 to match FIA GT3 specifications. Emphasis was placed on safety with BMW Motorsport producing an "FIA-approved safety cell in accordance with the very latest safety standards". Unlike the Z4 GT3, which used an engine derived from the BMW M3, the engine of the M6 GT3 was virtually unchanged from that of the production model of the M6 (and the BMW M5). The engine only faced some modifications for use in motorsport. In May 2015, at Dingolfing, BMW works driver Jörg Müller drove the M6 GT3 on its first roll-out to contribute a milestone to its development, and later the M6 GT3 was revealed near the end of the year.
The M6 GT3 showed its success on its debut year in 2016 when Rowe Racing clinched overall victory at the 2016 24 Hours of Spa with BMW works drivers Philipp Eng, Maxime Martin, and Alexander Sims at the wheel. The car also saw success in championships around the world, with wins in the VLN, Italian GT Championship, and Super GT Championship.
M6 GTLM
The BMW M6 GTLM is the racing version of the M6 created to participate in the IMSA WeatherTech SportsCar Championship and intended to replace the BMW Z4 GTE. The cars are entered by BMW Team RLL, debuting in 2016, with no wins in its debut season. The car would earn four class wins during the 2017 season before being replaced by the BMW M8 GTE for 2018.
