The 1971 auto racing season opened strongly in the United States with dominance in the major domestic series. In NASCAR, Richard Petty captured his third Winston Cup championship in commanding fashion, winning 21 of the 46 races he entered and posting 38 top-five finishes. Petty also secured his third Daytona 500 victory early in the year, while he and Bobby Allison together claimed roughly two-thirds of all race wins, highlighting the intense competition between the two stars in stock car racing’s growing national spotlight.
On the open-wheel side, USAC Championship Car racing saw Al Unser Sr. deliver a dominant performance to win the Indianapolis 500 for the second straight year, leading the final 83 laps and averaging a record 157.735 mph in his Vel’s Parnelli Jones Colt-Ford. However, under a restructured points system that separated paved ovals, dirt ovals, and road courses, Joe Leonard emerged as the overall USAC National Champion through consistent finishes.
Internationally, Formula 1 belonged to Jackie Stewart, who claimed his second World Drivers’ Championship driving for the emerging Tyrrell-Ford team. Stewart secured six victories across the 11-race schedule, with his young teammate François Cevert adding a win at the season-ending United States Grand Prix at Watkins Glen. Tyrrell also took the Constructors’ title, while Ronnie Peterson impressed in a March and occasional wins went to Ferrari and BRM.
In sports car endurance racing, Porsche overwhelmed the World Sportscar Championship with its formidable 917 models, winning nearly every round. The season’s crown jewel, the 24 Hours of Le Mans, produced one of the event’s most memorable performances: Gijs van Lennep and Helmut Marko piloted a Martini Racing Porsche 917K to victory at a record average speed, covering the greatest distance in Le Mans history up to that point under perfect conditions.
