context_page_description: The BMW M1 is a mid-engined sports car produced by German automotive manufacturer BMW from 1978 to 1981.
  In the late 1970s, Italian automobile manufacturer Lamborghini entered into an agreement with BMW to build a production racing car in sufficient quantity for homologation, but conflicts arose that prompted BMW to produce the car themselves. The resulting car was sold to the public, from 1978 to 1981, as the BMW M1.
  It is the first mid-engine BMW automobile to be mass-produced; the second is the i8 plug-in hybrid sports car.
context_section_description: The BMW M1 is the first car to be solely developed by BMW M and employs a 3,453 cc (3.5 L) M88/1 petrol six-cylinder engine with Kugelfischer-Bosch mechanical fuel injection and Magneti-Marelli ignition system. The engine was developed by Paul Rosche, who was also responsible for the S14 inline-4 engine and the S70/2 V12 engine. A version of this engine was later used in the South African version of the 745i, of which 209 examples were built between 1984 and 1986, as well as the E24 M6/M635CSi and E28 M5. The engine has six separate throttle bodies, twin-cams, 4 valves per cylinder, and generates a power output of 277 PS (204 kW; 273 hp) at 6,500 rpm and 330 N⋅m (243 lbf⋅ft) of torque at 5,000 rpm in the road version, giving the car a top speed of 260 km/h (162 mph). The engine was mated to a 5-speed manual transmission made by ZF Friedrichshafen equipped with a 40% locking limited slip differential.
