The BMW M10/M12 was an I4 piston engine produced from 1961 to 1983. Displacement ranged from 1499cc to 1990cc.

The engine was designed by Baron Alex von Falkenhausen, noted engineer and race driver. von Falkenhausen was asked to design a small-displacement (1.3 L) engine, but he felt that this would be insufficient for the company's future needs. Therefore, he designed a block that could be expanded to 2.0 L and delivered it at 1.5 L. The design was very successful, with over 3.5 million produced, and it served the company for over 20 years.
