High Quality Content by WIKIPEDIA articles! The BMW M50 is an I6 piston engine. It was introduced in March 1989 to replace the BMW M20 and was replaced by the BMW M52 in 1995. Displacement ranges from 2.0 L to 3.2 L. It is a DOHC 24-valve engine. A Technical Update or M50TU version from 1992 introduced VANOS variable valve timing. The M50 was not related to the M20 though it used the same 91 mm cylinder spacing, bore, and stroke at 2.0 L and 2.5 L. The 2.0 L (1991 cc) M50B20 was introduced with the 1989 520i. It has an 80 mm bore and 66 mm stroke and produces 150 hp (110 kW). From the '93 model year onwards, the engine received a 'technical update' which included the addition of VANOS (VAriable NOckenwellen Steuerung), BMW's variable valve timing system, on the intake cam. The engine thereafter became known as the M50TUB20.
