PORSCHE RACING HISTORY1983 - Nürburgring 1000 km
29 May 1983 - Nürburgring Nordschleife, Germany
Jochen Mass and Jacky Ickx win in Porsche 956
1st, 2nd, 3rd Overall : Group C - 1st, 2nd, 3rd : Group B - 1st, 2nd 3rd During qualifying Stefan Bellof produced what has since been called “The Impossible Lap,” completing all 20.83 KM in 6 minutes and 11.13 seconds. This meant an average speed around the lap of 202.1 KPH (125.56 MPH). Naturally, this put the #2 956 on pole, with the second place qualifying lap being almost 6 seconds slower. During the race, Bellof proved his mastery of the 956 and the Nordschleife again, setting the fastest race lap ever on the Nordschleife, a record that will never be beaten. That lap was 6 minutes and 25.91 seconds—only 14.8 seconds slower than his qualifying lap.
