Rudolf Uhlenhaut was a British-German engineer, driving engineer for Mercedes-Benz, and the father of Mercedes-Benz 300 SL and 300 SLR. He had a long association with the Mercedes-Benz racing programme of the 1930s and 1950s, and is best known for his road legal Uhlenhaut Coupé version of the 1955 Mercedes-Benz 300SLR race car.

The Mercedes-Benz 300 SL is a two-seat sports car that was produced by Mercedes-Benz from 1954 to 1957 as a gullwinged coupé and from 1957 to 1963 as a roadster. The 300 SL traces its origins to the company's 1952 racing car, the W194, and was equipped with a mechanical direct fuel injection system that significantly increased the power output of its three-liter overhead camshaft straight-six engine.
