The BMW M10 is a straight-4 SOHC piston engine produced from 1962 to 1988 with displacements ranging from 1499 cc to 1990 cc. It was first released in the New Class sedans and began to be phased out following the introduction of the M40 engine in 1987.

The engine was a commercial success for the Bavarian carmaker, with over 3.5 million produced in almost three decades across many BMW models.[1] It has a forged crankshaft, counterbalance weights, five main bearings and a chain-driven camshaft.[2] The block is made from cast iron and the head is made from aluminium.


It was also used as the basis for the turbocharged BMW M12 motorsport engine, which was used in the Formula One racing series by Brabham-BMW and others.

The engine was designed by engineer and race driver Baron Alex von Falkenhausen.[1] In the late 1950s, he was asked to design a small-displacement (1.3 L) engine, but felt that this would be insufficient for the company's future needs. Therefore, he convinced BMW that the capacity should be 1.5 L instead and he designed a block that could be expanded to 2.0 L in the future. The M10 Engine that resulted had a bore and stroke of 82mm by 71mm for a displacemnt of 1499cc. It utilized hemispherical combustion chambers, had an aluminum alloy head, and two large valves per cylinder, 39mm inlets and 35mm exhausts. Power was rated at 80bhp.
