The BMW M30 is a SOHC straight-six petrol engine which was produced from 1968 to 1995. With a production run of 27 years, it is BMW's longest produced engine and was used in many car models. The first models to use the M30 engine were the BMW 2500 and 2800 sedans. The initial M30 models were produced in displacements of 2.5 litres (2,494 cc ...

The M Coupe and M Roadster were initially powered by the engines from the E36 M3. This means that most countries initially used the 3.2 L version of the BMW S50 engine, while North American models initially used the less powerful BMW S52 engine.
