There are more 4-cylinder engines than any other engine type in the world. BMW's 4-cylinders are smooth and powerful. You can learn about yours here!




BMW models with 4 cylinder engines include:


MINI engines. The new MINI is powered by the four-cylinder, 1.6-liter "Pentagon" basic engine, which was developed jointly by BMW and Chrysler.

E36 M3

The E36 3 Series M40 1.8 and M43 1.6 are belt driven 8 valve units with cam belt drive. They are reliable and capable with few problems. The newer M42/44 1.8 and 1.9 16 valve units are a nice revving engine with a sporty character.

BMW E30 M3

Designed by the legendary Paul Rosche, the S14 engine used in the E30 M3 was constructed with an M10 bottom end, an M1/M635 CSi DOHC cylinder head with two cylinders cut off (how Roche built the first one) and four throttle bodies.

Baron Alex von Falkenhausen designed the M10 engine. A classic in design, the New Class engine was a high-revving 4-cylinder, single overhead cam powerplant with an all-aluminum cylinder head.
