The BMW M43 is an SOHC four-cylinder petrol engine which was produced from 1991-2002.[1] The M43 powered base-model cars, while higher performance models at the time were powered by the BMW M42 and BMW M44 DOHC engines. The M43 was produced at the Steyr engine plant.[2]
A version using natural-gas was produced for the E36 318i and the E34 518i.
Following the introduction of the BMW N42 engine in 2001, the M43 began to be phased out.
