The 1991 Pepsi 400 was the 15th stock car race of the 1991 NASCAR Winston Cup Series season and the 33rd iteration of the event. The race was held on Saturday, July 6, 1991, before an audience of 80,000 in Daytona Beach, Florida at Daytona International Speedway, a 2.5 miles (4.0 km) permanent triangular-shaped superspeedway. The race took the scheduled 160 laps to complete. In the final laps of the race, Melling Racing driver Bill Elliott would manage to mount a late-race charge to the lead, passing for the lead with 13 to go to take his 33rd career NASCAR Winston Cup Series victory and his only victory of the season. To fill out the top three, Junior Johnson & Associates driver Geoff Bodine and Robert Yates Racing driver Davey Allison would finish second and third, respectively. On lap 120 of the race, owner-driver Darrell Waltrip, along with RahMoc Enterprises driver Joe Ruttman, would both be involved in a crash on the track's back straightaway. Waltrip and Ruttman would both slide into the infield grass, and Waltrip's car, after hitting a bump in the infield, would then proceed to go into a series of violent flips, destroying Waltrip's car. Waltrip was not seriously hurt.
