The BMW M70 was a naturally aspirated single overhead camshaft V12 petrol engine, produced from 1987 to 1996 as the first production V12 BMW built. It was also the first German twelve-cylinder car engine of the postwar era, ahead of the Mercedes-Benz M120 by four years and the Volkswagen W12 by fourteen. Its design resembles two 2.5 litre M20 straight-sixes joined at 60 degrees, sharing the 91 millimetre bore spacing, 84 millimetre bore and 75 millimetre stroke. It differs from the M20 with an aluminium Alusil block, mass airflow sensors, electronic throttle control, a timing chain and hydraulic lifters, and it carries two Motronic 1.3 control units, one for each bank. The M70B50 powered the E32 750i and the E31 850i, and the unrelated S70/2 powered the McLaren F1.
