Having left Auto Union in 1938, Hans Stuck had the idea to break the absolute speed record for automobiles held by Captain George Eyston (575,1 km/h). Stuck had the ambition to be the first man faster than 600 km/h (373 mph). Due to an excellent connection to Ernst Udet of the Deutsche Luftwaffe, Stuck achieved two Daimler-Benz aircraft engines Type 603 (44.000 ccm, about 3.000 hp). Dr. Ferdinand Porsche was the one to construct the super race car. His ambition was to reach 650 km/h (404 mph). Responsible for the aerodynamic design were renowned specialists at the Germanaircraft manufacturer Messerschmitt. The car's weight was about 2.000 kg with three achsles, two of them driven, one-gear-transmission. The length was 8.50 m by 1.80 m width. Due to the outbreak of World War II, the prototype never had a chance to prove it's capabilities. From the factory it went directly to the museum.
