Mercedes-Benz M24 engine

The Mercedes-Benz M24 is a supercharged straight-eight engine of 5.0 or 5.4 litres that Mercedes-Benz built from 1934 through 1944. It is listed with three applications, the W31, the 500K and the 540K. In the 500K, a grand touring car built between 1934 and 1936, pressing the throttle fully engaged a Roots supercharger and the five litre straight-eight produced up to 160 horsepower, enough for more than 160 km/h. The 540K enlarged the displacement to 5,401 cc, and its twin updraft carburettors gave 115 hp, rising to 180 hp when the supercharger was engaged.
