6-Hours race for the World Championship of Makes and Can-Am race in July, 1972. In the endurance race, the Groupe 5 Porsche 917s and Ferrari 512s are gone. The races are now won by the open-top, 3-liter, Group 6 racers. The main combatants are Ferrari and the Ford-Cosworth powered Gulf Mirage teams.
Porsche may have been gone from the 6-Hour race, but they certainly came to play in the Can-Am. Team McLaren (Denny Hulme) and Penske Porsche (George Follmer) each had one win coming to the Glen, but the guard was changing. Follmer would go on to win the Can-Am title for Porsche in 1972, ending five years of McLaren domination.
Three days of photos this year. Friday was a practice day for both series. Saturday had Can-Am qualifying followed by the endurance race, which was won by Mario Andretti and Jackie Ickx driving a Ferrari 312PB. On Sunday, the Can-Am race was won by Denny Hulme in a McLaren M20. The galleries contain photos shot by myself (Kodak Instamatic) and my father (Minolta SLR).
