BMW M10/M12

When BMW launched the Neue Klasse saloon in 1962, survival rather than sport was on its mind. But it succeeded, and BMW then enjoyed many wins with its engine in the 1800ti, 2002 and first 3 Series, as well as in F2 with more than 300bhp. However, 1983 was the real turning point. Brabham needed a new F1 engine, so BMW created a 1.5-litre turbo derivative of the M10 .Compact and reliable, the M12 eventually hit 1400bhp. F1 banning turbos in 1989 ended its racing career.
