アウトウニオン
In 1934, Wanderer and others merged to form Auto Union, and the senior Porsche became the chief designer of their race cars. Both racing teams, Daimler-Benz and Auto Union, were also used for political propaganda by the National Socialists. They overwhelmingly dominated all the competitions of the 1930s. In 1938, Ferdinand Porsche senior left the Auto Union racing team when his contract expired.
