Auto Union Beginnings:
In succession: Auto Union Type A, Type B, Type C, Type C Streamliner, Type C Rekordwagen Avus, and Type D.
The cars were heavily influenced by the Benz Tropfenwagen Grand Prix cars of the early ’30s but destroyed other cars because of their sheer power even though they handled terribly. The cars ranged from 370hp to almost 550hp which was unheard of at the time.
