The "large wind tunnel" in Untertürkheim - Mercedes-Benz Passion eBlog

The „K-Wagen“ developed by Kamm between 1938 and 1941 was the prototype for an aerodynamically innovative passenger car. And the name „Kamm rear“ is still used today to describe the sharp spoiler lip at the tail end. Because of the war, it was not until 1954 that the wind tunnel became the first in the world to be used for measurements on original-size passenger cars. Since then, it has played a key role in developing the aerodynamic efficiency of the car – especially models bearing the Mercedes star.
