Mercedes-Benz M124 engine

The Mercedes-Benz M124 was a prototype supercharged 5.8 litre straight-eight engine manufactured by Mercedes-Benz in 1939. Its only recorded application was the 1939 Mercedes-Benz 580 K, a prototype car of the W129 series, so it never reached series production. The source article is a stub that gives the capacity, layout, supercharging, year and the single prototype application and nothing further, so the fuel, the power output and the people who designed it are not stated here.
