On the traditional 22.810 km long Nordschleife ("Northern Loop") version, the competition took usually 44 laps (1003.64 km, since 1967 1004.74 km) and lasted about eight hours, later less than six hours. While the 1974 event was shortened in the wake of the oil crisis, the 1976 race was extended by 3 laps and covered 1073.245 km.
The last race on the Northern Loop in 1983 was won by Jochen Mass and Jacky Ickx in their RothmansPorsche 956. In that year, due to the ongoing construction work, the track had been shorted to 20.832 km and provisional pits were used. This event saw the fastest ever timed lap of the Nordschleife when German driver Stefan Bellof lapped his Rothmans Porsche in 6:11.13 during practice, and an average of over 200 kph. Bellof also set the race lap record during that race lapping in 6:25.91.
Since 1984, the 1000 km races were run on the new, much shorter Grand-Prix-Strecke, while the 24 Hours Nürburgring stayed on the legendary long track. In 1991, the 1000 km races were first shortened to 480 km, then discontinued overall due to the demise of the World Sportscar Championship.
The 500 km Nürburgring was also similar event for smaller sportscars during the 1960s and 1970s.
VLN also runs a six hour endurance race, while covering only 4h in other heats. In 2010, for the first time a distance of more than 1000 km was covered by the winning Porsche 911 GT3.
Current record of most wins belongs to Stirling Moss who won the race in 1956, 1958, 1959 and 1960.
In 2010, the winning Porsche 911 GT3 R of the 6h ADAC Ruhr-Pokal-Rennen race was the first to cover more than 1000 km in a 6-hour VLN endurance race for GT3 and touring cars, lapping the 24,369 km long modern version of the Nordschleife 42 times for 1023.498 km in a time of 6:06:56.091. The 2012 winner, a Mercedes-Benz SLS AMG GT3, covered the same distance in a time of only 6:01:29.541, at an average of 169.879 kph.
As a part of the Oldtimer Festival in 2010 the tradition and name of the renowned ADAC 1000 km of Nürburgring will be continued by the motor sport club DAMC 05. In contrast to former years, the race is organised for older cars and therefore the term “classic” was added to the name.
