The 24 Hours
Nürburgring is a GT and touring car endurance racing event on the
Nürburgring, inspired by the famous 24 Hours of Le Mans and the
Spa 24 Hours. The venue of this event is held on the Nürburgring
Nordschleife (the 22.835km north loop), and is geared towards amateur
drivers and primarily production cars. Conversely, the related 1000km
Nürburgring is geared towards professional teams and drivers, and
is held on the GP
circle.
Officially
called ADAC 24h Rennen Nürburgring in German, it was introduced
in 1970 by the ADAC as a low cost alternative to the 1000 km Nürburgring
(a sports car racing event that counted towards the World Sportscar
Championship from 1953 to 1992).
Typical entries
range from standard road cars to European Touring Car Championship
vehicles, and sports cars like the Porsche 911. As interest had
dropped in the 1990s when only rather standard FIA Group N cars
competed, stronger vehicles were admitted since 1999, like the Zakspeed
Chrysler Viper GTS-R which originally was built to FIA GT2-spec,
modified Deutsche Tourenwagen Masters cars from Opel and Abt Sportsline-Audi,
and the Schnitzer Motorsport-entered BMW M3 GTR V8 that had been
run in the 2001 American Le Mans Series.
Due to various
changes and versions of the Grand
Prix track, the overall length of the track varied from the
original 22.835 km (14.189 mi) to nearly 26 km (16.2 mi) of the
maximum length configuration which was in use in 2002 and 2003,
after the GP
track had been extended by the Mercedes Arena. A 25.3 km (15.7
mi) variant is in use since 2005, bypassing the Arena which is used
for a parking zone for the competitors of the other races.
For practice,
230 cars are allowed, 220 qualify for the race, driven by 800 or
more drivers, as 2, 3 or 4 can share a car. One driver is allowed
to drive 150 minutes nonstop, and can enter on two cars, yet a rest
time of at least 2 hours has to be observed between two turns.
