The Mercedes-Benz W25 succeeded the SSKL, an extremely successful car in the 1920s and early 1930s. Its design was inspired by a production car, namely the 380 that was launched at the Berlin Motor Show in February 1933. The 32-valve, supercharged inline eight-cylinder engine with dual overhead camshafts was a highly advanced power plant in its day. Its output for the first race was a massive 354 hp. This car debuted at the Eifelrennen on June 3, 1934. Piloted by Manfred von Brauchitschunder, starting number 20, the W25, was victorious. This was the event that marked the birth of the Silver Arrow legends. In all, Mercedes-Benz W25 scored 16 victories in Grand Prix events as well as other major races.
