He has played a key role in every one of Porsche’s 16 overall race victories between 1970 and 1998 at the 24 Hours of Le Mans.
[3] The young engineer from the Technical University of Munich was soon given the job of cooling the gearboxes of the powerful 917 racers which had broken down in 1969.
[3][1] His first task was successful and the Porsche 917 dominated the event in 1970 as well as in 1971, the first year Singer attended the great race.
[2] Singer was involved in the 911 Carrera RSR and RSR Turbo 2.1 from 1972 to 1974[3] Singer was then given the task of developing the Porsche 911 road car for racing,[1] and in doing so he created eventually what is by far the most successful customer race car that Porsche ever produced: the Porsche 935 which won at the 1979 24 Hours of Le Mans outright, a remarkable feat for a modified 15-year-old road car design.
[2] Following this, Singer designed the bodywork of the Porsche 956 and 962 Group C cars[4] which won 7 24 Hours of Le Mans titles [1] and three Manufacturers’ and two teams’ World Championships between 1982 and 1986[3] In the 1990s, Singer engineered the Porsche WSC open sports car which claimed two victories in 1996 and 1997.
