On May 27, 1934, Auto Union racing cars went to the starting line for the first time on the Avus circuit in Berlin, driven by Prince Hermann zu Leiningen, Hans Stuck and August Momberger who came in third after the other two had retired. The cars they drove were Porsche’s original design (later referred to as Type A), with a 4.3 liter V16 engine developing 295 bhp.
