1975 National 500

The 1975 National 500 was a NASCAR Winston Cup Series race that took place on October 5, 1975, at Charlotte Motor Speedway in Concord, North Carolina.

The event was complemented by a Late Model Sportsman event that counted for points in the NASCAR-sanctioned World Service Life 300 (prior to 1982, drivers could drive as many Late Model Sportsman races combined on the short tracks and superspeedways) that, after NASCAR changed the format of the series in 1982, is now the NASCAR Xfinity Series after it became a touring format. Both of those races took place on the same race track.

ABC Sports provided delayed coverage of the race, one week later.

Race report
It took three hours and forty-seven seconds for the race from its 12:30 P.M. scheduled green flag time. The race ended at approximately 4:07 P.M.

After failing to finish the race at Martinsville, Richard Petty defeated David Pearson by 0.26 seconds for the 176th win of his career. Richard Petty's championship lead over Benny Parsons would give him an 878-point advantage for the title; which was the largest points lead that anyone has ever accumulated in the Latford system used by NASCAR during the mid-1970s. Bruce Hill was the most dominant rookie during the 1975 season; charging to a 27th-place finish.

Pearson would win the pole position with a speed of 161.701 mph during qualifying; his next pole position start would be at the 1976 World 600. More than 61,000 spectators would attend with seven cautions for 53 laps. The average speed was 132.209 mph; over 334 laps on the oval track spanning 1.500 mi. There were 42 drivers on the grid; all of them were born in the United States of America. Coo Coo Marlin was the last-place finisher due to an engine problem on lap 8 in his 1975 Chevrolet Chevelle Laguna automobile. Charlie Glotzbach led one lap early in this race before a transmission failure sidelined his one-off entry in the #3 Kmart Chevrolet. It was the last lap he ever led in Cup competition.

Darel Dieringer would make his final NASCAR appearance in this race; finishing in seventh place in the process.

Notable crew chiefs who in the race included Tim Brewer, Jake Elder, Travis Carter, Harry Hyde, Dale Inman, Tom Vandiver, and Bud Moore.
