Contents

Design

The M194 is based on the M186 engine from the then-new W186 300. [1] It is a four-stroke engine with three Solex carburetors and two valves per cylinder. [2] 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. [3] It is also mounted behind the front axle for better weight distribution. [4] Only 10 M194 engines were made for the W194 300SL racer; the first three cars had around 170 kW (228 hp), while the remaining seven had around 180 kW (241 hp). [5]
