1928→1932 Mercedes-Benz 720 SSK

The Mercedes-Benz is considered the summit of a six-cylinder series which debuted in the 1920s, in the times of the DMG (Daimler Motoren Gesellschaft or Daimler Engine Company). For many years the S, SS, SSK models and the lightweight variant SSKL dominated international racing – often with Rudolf Caracciola at the wheel. On 13 and 14 June 1931 the duo Boris Iwanowski/Henri Stoffel drove the fastest lap at Le Mans, 7 : 03 minutes (139.2 km/h), going on to reach the second place in the overall result of the 24-hour race.
