In 1933 Mercedes-Benz made the landmark decision to design its own racing car (designated number W 25) according to the 750-kilogram race formula that applied from 1934 and to send it out onto Europe's racetracks. The engineers worked flat out on the concept for what the company hoped would be a winning car of the future. With a slim body, a front-mounted, mechanically supercharged, inline eight-cylinder engine, individual wheel suspension and a transmission mounted directly on the rear axle, the intention was to bring home motorsport titles. The results were impressive and the plan to triumph on the racetrack did not appear to be too ambitious. With an output of 260 kW (354 hp), the car reached top speeds of around 300 km/h in its first season.
