Mercedes-Benz M07 engine

The Mercedes-Benz M07 is a 7.7 litre straight-eight engine that Mercedes-Benz designed, developed and built from 1930 through 1938, offered both naturally aspirated and supercharged. It powered the first version of the Mercedes-Benz 770, the Großer Mercedes ultra luxury car, whose W07 version used an inline eight-cylinder engine of 7,665 cc with an overhead camshaft and aluminium pistons. Without supercharging it produced 150 bhp at 2,800 rpm, and an optional Roots supercharger engaged at full throttle raised output to 200 bhp, enough for 160 km/h. Governments were the main customers for the car, and 117 W07 cars were built until 1938.
