Mercedes-Benz M194 engine


The M194 is a straight-six engine produced by Daimler-Benz in limited numbers for its 1952 W194 300SL sports car racer that was entered in endurance races, winning most of them.

Design

The M194 is based on the M186 engine from the then-new W186 300. It is a four-stroke engine with three Solex carburetors and two valves per cylinder. The engine is titled 50 degrees to the left in order to reduce the height of the hood, and uses a dry sump lubrication system instead of an oil pan and reservoir. It is also mounted behind the front axle for better weight distribution. Only 10 M194 engines were made for the W194 300SL racer; the first three cars had around, while the remaining seven had around.

300 SL Kompressor (M197)

For the Nürburgring sprint race event that supported the 1952 [German Grand Prix], which did not favour endurance over power, Mercedes had announced a surprise. One car was fitted with the M197 engine version that had a blower, which was permitted in the "S 5000-8000cc" class, with the supercharged 3 litre treated as 6 litre. This "300SL K" had a bulge on the left side of the hood for the additional Kompressor, and was only used in practice, by Kling. Being tested but not raced at a GP race weekend, it basically was the last Mercedes-Benz supercharged [Grand Prix racing engine]. The normal cars won 1-2-3-4 anyway.
