Mercedes-Benz M194 engine

The Mercedes-Benz M194 is a straight-six engine that Daimler-Benz produced in limited numbers for its 1952 W194 300SL sports car racer, which was entered in endurance races and won most of them. It is based on the M186 of the new W186 300, specifically the M188 of the two-door 300S with three Solex carburetors and 150 horsepower. It is a four-stroke inline-six with two valves per cylinder, tilted 50 degrees to lower the bonnet, with dry sump lubrication, and it sits behind the front axle for better weight distribution. Only ten were made, the first three giving about 170 horsepower and the other seven about 180. A supercharged M197 version ran in practice for a sprint race at the Nürburgring.
