Mercedes-Benz developed this W 25 streamlined racing car in 1937 specially for the open-formula race on the AVUS circuit in Berlin. Manfred von Brauchitsch drove this W 25 flat out over the long straights and through the new high-banked corner. Hermann Lang won the race in a similar car at an average speed of 162.7 mph – a figure which remained unsurpassed until 1958.
