The BMW M6 is a high-performance version of the 6 Series marketed under the BMW M sub-brand from 1983 to 2018 (with a break 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. 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)

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.

Other changes included BBS RS wheels, a rear lip spoiler, a larger front air dam, larger front brakes and revised suspension with a 10 mm (0.4 in) lower ride height.

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 0–97 km/h (0–60 mph) in 5.8 and 6.8 seconds for the European and North American versions respectively. The curb 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.

A total of 5,855 cars were produced. Of these, 1,677 cars were imported to North America. Due to the elongated front and rear bumpers, the length of the U.S. models is 4,923 mm (193.8 in).

Production of the E24 M635CSi/M6 ended in 1989.

Negative 2008 Bmw M6 car reviews

Jamil Ward 2024-01-01

My M6 had a tendency to consume oil at a very early stage, at just 1,800 kilometres, and used an average of 1 litre of oil per 1,000 kilometres until BMW agreed to replace the engine. Unfortunately, I also experienced a faulty tyre pressure indicator which, combined with the need to top up the oil every 1,000 kilometres, made BMW's fastest convertible slower on trips than my daughter's Smart ForTwo. Additionally, I found it difficult to source parts and tyres for the car in Australia. Overall, my experience with the car was not ideal, but I hope that BMW can improve on these issues in the future.

This car is incredibly fun to drive and the handling is second to none.
Solon Kirlin 2024-10-12

What a fantastic car! I started my addiction with a 645 and then a 650, both of which were great cars - fun to drive, quick, and with superior handling. However, the M6 is in a class of its own. It's an amazing combination of style and engineering superiority. It effortlessly cruises through daily traffic, with no hint of the beast lurking beneath the surface, just waiting for a chance to get loose. It never fails to turn heads and always thrills when that big V10 jumps to life with the touch of a button.
Cordelia Keeling 2024-10-04

I'm really impressed with my new M6! It's replaced my 911 C4S and BMW X5, and it blends the best of both worlds with speed, firmness of drive, and wonderful comfort. I've received so many compliments on its looks and growl. It took me a few days to master the shifting smoothly, even in automatic, but the optional M-mode significantly adds horsepower. Despite the luxurious drive, the handling rivals the 911 (almost). The heads up display and paddle shifters in M-mode are cooler than my cousin's F430, and they make driving easier. The sport seats are the most comfortable I've ever experienced. The HD sound playing from Satellite or FM is fantastic, and the voice command audio makes it easy to get the music right while paying attention to the road. Overall, it's been a great ride - A+!
Jennings Wolff 2024-08-16

This car is truly an amazing engineering feat! It's meant to be driven hard, not tamely, and the entire vehicle responds incredibly well when pushed to its limits. And let's not forget, it's the ultimate eye-catcher, so get ready to turn heads! So go ahead and enjoy!
Macey Pfeffer 2024-07-14

This car is truly awesome! It has great stability in turns at high speed and comes with a nice base package that includes most of the toys you could want. Plus, it's a fun car to drive with the top up or down.
