The ADAC Zurich 24-hour race on the Nürburgring Nordschleife:
The 24-hour race has been held on the Nürburgring Nordschleife since 1971. Due to a two-year interruption due to the oil crisis, the 40th anniversary did not take place until 2012.
In the early years, the 24-hour race still had more of a leisure character and was mainly driven by amateurs. It was not until the year 2000 that significantly more powerful vehicle classes were introduced and the racing event became increasingly professional in character. As early as 2003, the starting field consisted of many well-known racing teams and factory teams. To date, the 24-hour race on the Nordschleife has established itself as one of the best-known endurance races in the world. Due to the track length of more than 25 km (Nordschleife and GP track), very large starting fields of 190 to 220 participating vehicles are possible. Accordingly, in each race about 700 to 800 drivers will start.
