The 1971 NASCAR Winston Cup Series season began on January 10 and ended on November 20. Richard Petty was the champion for this Winston Cup season. After 20 years of being named the NASCAR Grand National Series, R. J. Reynolds first became the primary sponsor in a decade where the growing anti-tobacco movement banned its advertisement on television and motorsports was the ideal place to place their advertisements. Through NASCAR, Winston merchandise was unveiled to live viewers of the races (since they were not allowed to advertise to a televised audience). This kind of merchandise would also be given out at stores that sold cigarettes in subsequent years. Race car drivers were encouraged to smoke cigarettes (when not racing) until the mid-2000s brought in strict drug testing policies in addition to a smoking cessation program by Nicorette, a GlaxoSmithKline brand (Goody's Headache Powders, a long-time NASCAR sponsor, is a GSK brand; as of 2023, GSK sponsors both the Truck series race, and the spring Cup race at Martinsville Speedway).
Note: Some races were combined races for Grand American and Grand National cars. Races marked Combined Races were won by Grand American cars. The driver who finished first among Grand National cars is listed.
The Miller High Life 500 was run on February 28 at Ontario Motor Speedway. A. J. Foyt would win this race after more than three hours of racing (from the pole position).
The 1971 Myers Brothers 250 was a NASCARWinston Cup Series event that took place on August 6, 1971, at Bowman Gray Stadium in the American community of Winston-Salem, North Carolina.
Due to the reduced sponsorship money being given out by the "Big Three" automobile companies in Detroit, NASCAR decided to hold six of their smaller Winston Cup Series races in conjunction with the "minor league" NASCAR Grand American Series.
As Bobby Allison was not racing in a Grand National car, he never received credit in that series, but was credited with a Grand American Series ("pony" cars) win. Richard Petty, who finished second in a Grand National car, was never given credit for the class win. Under current rules used in various combination races among cars in NASCAR series, Petty would be credited with a series win.
This was the first season where NASCAR's premier racing series was called the Winston Cup. All previous seasons were known as either Grand NationalorStrictly Stock.
