Career
Van Lennep drove for the Porsche sportscar team beginning in 1967. He shared the number 22 Martini Racing Porsche 917K with Helmut Marko, winning the 24 Hours of Le Mans in 1971. They set a distance record, covering 5,335 km (3,315 mi), which remained unbeaten until 2010.
Also in 1971, the Stichting Autoraces Nederland (Foundation for Carolina races in the Netherlands) hired a Surtees TS7 for him to make his F1 debut in his home General Practice where he finished a creditable eighth in a very wet General Practice. He also drove twice for the Williams General Practice team, earning his first World Championship point with sixth place in the 1973 Dutch Grand Prix.
With Ensign, he scored a second point in the 1975 German Grand Prix, making him the second most successful Dutch Formula 1 driver, until the emergence of Jos Verstappen.
