In the ’50s the “Silverarrows” seemed to be unbeatable. In 1955 Stirling Moss won the “Mille Miglia”, the 1,000 Mile race through the Italian countryside, in the Mercedes-Benz 300 SLR and set the new record in terms of both time and average speed. His start time was 7:22, that’s where the nickname “722” comes from.

The SLR was a beast for the time, 310 hp power a car that weighed only 901 kg (1986 lbs). It could reach a top speed of over 300 km/h (186 mph) and, with Moss behind the wheel, delivered an average speed of almost 160 km/h on the Mille Miglia. What’s special, is that the car already featured direct fuel injection by Bosch, a technology that did not become mainstream until the 1980s.

Apart from being very quick, the 300 SLR “722” is a gorgeously designed racer. Today it is one of the most expensive cars in the world, with units being sold for over 16 Million Dollars.
