BMW M6 is a luxury car
In 1983 BMW took the M88/3 engine, a modified version of the M88/1 from the BMW M1 and put it in the E24 chassis of the BMW 6-Series, creating the M635CSi (called M6 in North America).
The M6 was critically acclaimed throughout its lifespan for its elegant, aggressive "shark-nose" styling, its luxury equipment, and its performance. A top speed of 158 mph (254 km/h)[citation needed] makes the European version the second fastest BMW ever built next to the M1. This is due to all other BMW models being electronically restricted to 155 mph (249 km/h). An M6 can be distinguished from other E24 models by a larger front air dam, a rear spoiler, BBS wheels, colour matching side view mirrors, M badges on the grille and back, and slightly larger front brakes.
In North America (United States and Canada), the E24 M6 was fitted with the catalyzed S38B35 motor, producing 256 hp (191 kW) and 243 ft·lbf (329 N·m) of torque. The non-catalyzed version produced 286 bhp (213 kW) and 251 lb·ft (340 N·m) of torque. The non-catalyzed versions were only available in Europe, though there were 538 catalyzed M635csi models sold in Europe in 1988 and 1989. The 1988 and 1989 M6s were "world cars" with the same bumpers and aerodynamic treatments in all markets.The M6 achieved 0-60 mph (97 km/h) time of 6.0 and 6.8 seconds for the European and American versions, respectively.Quarter mile times for the European version have been recorded at 14.5 seconds while the charge to 100 mph (160 km/h) is achieved in 15 seconds. However, Car and Driver Magazine tested the U.S. M6 in July 1987 and achieved a 0-60 mph (97 km/h) time of 6.1 seconds.[citation needed] Also in 1987 Road and Track featured the U.S. M6 as one of the 10 fastest cars in America.[citation needed] Production of the M6 ended in 1989, with 5,859 cars sold, 1,767 of which were North American (U.S. & Canada) models.
