Mercedes-Benz M186 engine
The Mercedes Benz M186 Engine was a 3.0–litre single overhead camshaft inline-6 developed in the early 1950s to power the company's new flagship 300 "Adenauer" (W186) four-door saloon. It made its debut at the Frankfurt Motor Show in April 1951.

The Mercedes-Benz W186 Model 300 was a four-door luxury sedan produced by Mercedes-Benz between 1951 and 1957. It was the company's flagship model at the time, succeeding the World War II era W150. Three versions were produced in succession, known informally as the 300a, 300b, and 300c. An enlarged "300d" variant built on the W189 chassis succeeded it in late 1957.
