BMW M1 Group 4 Challenge 2010 v1.0

The BMW M1 (BMW type code E26) is a sports car produced by German automotive manufacturer BMW from 1978 to 1981. In the late 1970s, Italian 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 result was sold to the public, from 1978 to 1981, as the BMW M1.

It is the first mid-engined BMW to be mass-produced, the second is the BMW i8.

The BMW M1 is the first of the M cars and employs a 3,453 cc (3.5 L; 210.7 cu in) M88/1 petrol six-cylinder engine with Kugelfischer mechanical fuel injection. A version of this motor was later used in the South African version of the BMW 745i, of which 209 examples were built between 1984 and 1986, as well as the E24 BMW M6/M635CSi and E28 BMW M5. The engine has six separate throttle bodies, twin-cam 4 valves per cylinder producing 277 PS (273 bhp; 204 kW) at 6,500 rpm and 330 N⋅m (243 lbf⋅ft) at 5,000 rpm in the street version, giving a top speed of 260 km/h (162 mph). Turbocharged racing versions are capable of producing around 850 hp (634 kW).
