The BMW M44 is a water-cooled inline four-cylinder petrol engine developed by BMW with a displacement of 1895 cm³ and four-valve technology based on the BMW M42 . It has two overhead camshafts . The valves are actuated by speed-resistant roller rocker arms instead of the conventional bucket tappets with hydraulic valve clearance compensation. The duplex roller timing chain was retained. Due to the longer stroke, a new crankshaft with four instead of eight counterweights was used, which was now cast instead of forged as in the M42. The diameters of the journals remained the same as in the predecessor, which is why the crank drive is often used for tuning purposes. The Differentiated Suction System (DISA) and the Motronic M 5.2 in conjunction with a hot wire air mass meter were used.

The M44 was used in the BMW E36 , as well as in the BMW Z3 Roadster.
