History
For the first time, an M20 engine with 12 valves and a SOHC belt drive was introduced in 1977 for the BMW 520/6 and 320/6, and had a completely new design. With a volume of 2.0 to 2.7 liters, he was the "younger brother" of the BMW M30 engine, which had a volume of up to 3.4 liters. The M20 was designed to replace 4-cylinder engines and was born out of the conviction of BMW engineers that an engine with small six cylinders has greater development potential than an engine with 4 large cylinders (with a volume of 2 liters or more).
General information
The M20 was installed on the BMW E12 , E21 , E28 , E30 and E34 .
