The BMW 1 Series M Coupé is a high-performance version of the BMW 1 Series Coupe, developed by BMW's motorsport branch BMW M. It is currently the smallest and least expensive M model available. The name was chosen to avoid confusion with the original BMW M1.
the 1 Series M Coupé uses a M-tuned, twin turbocharged version of the N54engine, as found in the 335is and Z4sDrive35is. Still a 3.0-litre inline six-cylinder engine with direct injection, it produces 335 hp (250 kW) at 5900 rpm and 332 lb·ft (450 N·m) torque from 1,500 to 4,500 rpm (with .9) overboost). The redline is 7,000 rpm. Official 0-60 mph time is 4.7 seconds, quarter mile (~400 m) in 13.2 seconds.The car is electronically limited to 155 mph (250 km/h) top speed. There is an M Drive button that activates a quicker throttle response program. The sole available gearbox is a six-speed manual transmission with an M gearshift knob, dry sump lubrication system, and 3.15:1 final drive ratio.
The body on the BMW 1 Series M Coupé has been modified as well, giving the car a significantly wider track and bigger body, as well as a body kit to distinguish it from the standard 1 Series. Despite the car's larger size, it is 77 lb (35 kg) lighter, giving it a weight of 3,296 lb (1,495 kg).
