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. Production of the M6 ended in 2018 and it was replaced by the BMW M8 (F91/F92/F93) in 2019.
E24 M635CSi/M6 (1983–1989)
|BMW M635CSi / M6 (E24)|
|Body and chassis|
|Body style||2-door coupé|
|Wheelbase||2,620 mm (103 in)|
|Length||4,755 mm (187.2 in)[a]|
|Width||1,725 mm (67.9 in)|
|Height||1,354 mm (53.3 in)|
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 supercar). In most countries, the model was badged the M635CSi, however the equivalent model in North America and Japan was simply badged in "M6".
The European-specification M635CSi used the M88/3 engine (without a catalytic converter), which generated 210 kW (286 PS; 282 hp) at 6,500 rpm and 340 N⋅m (251 lb⋅ft) at 4,500 rpm. The M6 version, sold in North America and Japan, used the S38B35 engine (with catalytic converter), which generated 256 hp (191 kW; 260 PS) and 330 N⋅m (243 lb⋅ft) at the same engine speeds. 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. The sole transmission for all models was a 5-speed Getrag 280 manual transmission.
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. Production of the E24 M635CSi/M6 ended in 1989.
According to BMW, the car can accelerate from 0–97 km/h (0–60 mph) in 5.8 and 6.8 seconds for the European and North American versions respectively. The kerb weights of the 1987 models are 1,515 kg (3,340 lb) for the M635 CSi and 1,619 kg (3,569 lb) for the M6. A top speed of 255 km/h (158 mph) made the European M635CSi the second fastest BMW automobile ever built next to the M1. The quarter mile time for the M635 CSi has been recorded at 14.5 seconds while 161 km/h (100 mph) is achieved in 15 seconds.
E63/64 M6 (2005–2010) 
|BMW M6 (E63/E64)|
|Body and chassis|
|Engine||5.0 L S85 petrol V10|
|Wheelbase||2,781 mm (109.5 in)|
|Length||4,872 mm (191.8 in)|
|Width||1,854 mm (73.0 in)|
|Height||1,377 mm (54.2 in)|
Following a hiatus in M6 production for 16 years, the M6 version of the E63/E64 6 Series was introduced in 2005. The M6 uses the same BMW S85 V10 engine and SMG-III automated manual gearbox as the E60 M5.
The M6 had two modes for engine power: a "P400" mode in which the engine has a rated power output of 294 kW (394 hp) and a "P500" mode in which the engine has a rated power output of 373 kW (500 hp). Manufacturer claimed performance included a 0-62 mph (100 km/h) acceleration time of 4.6 seconds. The top speed was electronically limited to 250 km/h (155 mph) or 305 km/h (190 mph) if the optional M-driver's package is fitted.
The coupe version weighs 1,710 kg (3,770 lb) and the convertible version weighs 2,005 kg (4,420 lb). Weight reduction measures include a carbon fibre roof (for the coupe only), thermoplastic quarter panels, aluminium doors, aluminium bonnet (hood) and a carbon-fibre boot (trunk) lid.
From 2007 a 6-speed manual gearbox was offered in North America, only 701 examples were produced with a manual gearbox (323 Coupes and 378 Convertibles).
Production of the M6 ended in mid-2010, with sales over the five-year run totalling 9,087 for the coupe and 5,065 for the convertible.
F06/F12/F13 M6 (2012–2018) 
|BMW M6 (F06/F12/F13)|
|Body and chassis|
|Engine||4.4 L S63 twin-turbo petrol V8|
|Wheelbase||2,850 mm (112.2 in)|
|Length||4,897 mm (192.8 in)|
|Width||1,919 mm (75.56 in)|
|Height||1,369 mm (53.9 in)|
The official performance figures state the acceleration time from 0–100 km/h (0–62 mph) in 4.2 seconds for the coupe and Grand Coupe, and 4.3 seconds for the convertible. The top speed is electronically limited to 250 km/h (155 mph), or 305 km/h (190 mph) with the optional M-driver's package. The differential is an electronically-actuated ("Active M") limited slip differential. The kerb weight for the coupe is 1,925 kg (4,244 lb), the kerb weight of the convertible is 2,055 kg (4,531 lb) and the kerb weight of the Gran Coupé is 1,950 kg (4,299 lb).
The front of the car has a newly designed M kidney grille with an “M6” badge – a homage to the first generation of the M6. The lead exterior designer of the F12/F13/F06 6 Series was Nader Faghihzadeh.
With the 2014 Competition Package, the M6 comes with a sportier exhaust system with black tips, stiffer springs, dampers, and anti-roll bars, steering is more direct than the base M6, the twin-turbocharged V8 engine utilised in the M6 is updated and is rated at 423 kW (567 hp) and 680 N⋅m (502 lb⋅ft) of torque. This results in a 0 to 100 km/h (62 mph) acceleration time of 3.9 seconds for the coupe and Gran Coupe versions.
In 2016, the Competition Pack engine was upgraded to 441 kW (591 hp) and 700 N⋅m (516 lb⋅ft) of torque, resulting in a 0 to 100 km/h (62 mph) acceleration time of 3.8 seconds for the coupe and Gran Coupe versions.
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 Spa 24 Hours 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.
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.
