The BMW M40 is an SOHC straight-four petrol engine which was produced from 1987–1994.[1][2] It served as BMW's base model four-cylinder engine and was produced alongside the higher performance BMW M42 DOHC four-cylinder engine from 1989 onwards.

Compared with its M10 predecessor, the M40 uses a belt-driven camshaft,[3] and hydraulic tappets. Like the M10, the M40 uses an iron block and an aluminium head. Fuel injection for the E30 versions is Bosch Motronic 1.3,[4] and the E36 versions use Bosch Motronic 1.7.[5][6]

Following the introduction of the BMW M43 engine in 1991, the M40 began to be phased out.
