The Avus is the very first road in Europe that was only allowed to be used by cars. It is located in the southwest of the city in Berlin-Wilmersdorf. Construction began in 1913. However, the First World War and the years after that caused delays in construction. In 1921, however, the time had come: the first race could take place on the track. This car race was followed by a motorcycle race in June 1922. The road is predestined for competitions because the road is almost dead straight and has a length of 8.3 km. Only at the end there were initially two loops. This meant that the route was around 19 km long at the opening times. The last race on the historic road took place in 1998.
