BMW M20

Automotive Engines

The BMW M20 was a single overhead camshaft straight-six petrol engine built from 1977 to 1993, the smaller companion to the long-running M30 and affectionately called the Little Six beside the M30 Big Six. BMW designed it to fill the gap between the M10 four-cylinder and the M30, which was too large and heavy for the engine bay of the E21 3 Series. It debuted at the 1977 IAA in 2.0 litre carburettor and 2.3 litre fuel-injected forms, and a bigger bore in 1982 led to 2.5 and 2.7 litre versions. It drove its camshaft with a belt rather than a chain, was the basis for the M21 diesel, and is loosely related to the M70 V12.
