Auto Union and Mercedes Benz were the great racing cars of the 1930’s. Funded by Hitler in another attempt to prove German mastery, these cars were in fact, just that. Revolutionary racecars that dominated the other challengers like Alfa Romeo from Italy and Bugatti and Delahaye from France. The Auto Union, today’s Audi, featured the first rear engine racecar.

Spa Francorchamps was the site of the 1939 Belgian Grand Prix, won by Herman Lang in the W125 Benz. This is the victory poster published by Mercedes Benz after the race.
