Why it matters

The Schlörwagen, nicknamed the Göttinger Ei, was a full-size test of a single-volume body of wing-section shape with a closed underside, and measured a very low drag coefficient in the wind tunnel. It stayed a research vehicle.

History

Karl Schlör moved in 1936 from Krauss-Maffei to the Aerodynamische Versuchs-Anstalt Göttingen. A model measured a drag coefficient of 0.113, which led to the decision to build the car. A modified Mercedes-Benz 170 H chassis was used and the aluminium body was made by Gebrüder Ludewig in Essen; the finished car was shown in 1939 and measured about 0.186 in the AVA wind tunnel.

After the tests the car was put aside as the institute's automotive research was given up in wartime. It was later fitted experimentally with a Russian radial engine and propeller and used as a propeller test rig. Its later fate is unclear, with one report saying it was taken to England.
