The third evolution of Auto Union race cars, Type-C, appeared in 1936 and was designed by Ferdinand Porsche. V16 engine with Roots supercharger was extended to 6005 cc and was capable of 520 bhp at 5000 rpm. It was the largest possible design within the 750-kg weight limit. New Auto Union car became more competitive than B-type of 1935, and allowed Rosemeyer to win the European Drivers’ Championship in 1936, established by the Association Internationale des Automobile Clubs Reconnus (AIACR). Auto Union continued to use C-type in 1937, but with less success. Couple of the C-type in 1937 were built in a streamlined version in order to use it for speed record attempts. The racing debut of this streamliners was at Avusrennen 1937, where it were driven by Bernd Rosemeyer and Italian Luigi Fagioli, who joined Auto Union from Mercedes. Italian had the privilege to be the only driver who drove for both Mercedes-Benz and Auto Union, the major rivals of the Golden Era of 1934 – 1939. At Avus Fagioli retired in the preliminary heat due to broken transmission. Rosemeyer was 2nd in Heat 1 and fourth in the final.
