How Dauer Gave the Porsche 962 New Life at Le Mans
In 1992, changes to the World Sportscar Championship rules saw Porsche 962 numbers falling off. This was also true at the 24 Hours of Le Mans and Porsche was in search of a way to remain competitive in the race as its cars were outdone by other entrants. Their chance came through a loophole when Automobile Club de l'Ouest (ACO) required no specific number of road-going examples in its homologation requirements.
Dauer had already turned the 962 into a street-legal car and Porsche decided to work with them to bring it back to the forefront in racing. There were only a few changes that had to be made to make the car compliant. Since the production car had a trunk, the requirement for suitcase storage had already been filled.
Three more changes were required to make the car legal. They had to fit the car with narrower tires, a larger fuel tank, and an engine restrictor. They hoped to overcome the drawbacks of the narrower tires with a larger fuel tank that would allow cars to stop less frequently. There were two Dauer 962 Le Mans race cars built and they lived up to expectations scoring a win in the 1994 24 Hours of Le Mans. A short time later, the ACO closed the loophole by requiring a minimum number of production cars and neither the Dauer, nor Porsche 962s would race again.
