The DB 603 powered several aircraft, including the Dornier Do 217 Dornier Do 335 Heinkel He 219 Messerschmitt Me 410 and Focke-Wulf Ta 152

Design and development

The Mercedes-Benz T80 land speed record car, designed by aircraft engineer Josef Mickl with assistance from Ferdinand Porsche and top German Grand Prix motor racing racing driver Hans Stuck incorporated the third prototype DB 603. It ran on pure alcohol with MW 50 and was tuned to amp;nbsp;— enough, it was believed, to propel the aerodynamic three-axle T80 up to 750 km/h on the Dessau autobahn in January 1940 during Rekord Woche(Record/Speed Week). Due to the outbreak of the war in September 1939, the T80 (nicknamed Schwarz Vogel "Black Bird") never raced. The DB 603 engine was removed from the vehicle for use in fighter aircraft.
