1991 Mello Yello 500

The 1991 Mello Yello 500 was the 26th stock car race of the 1991 NASCAR Winston Cup Series and the 32nd iteration of the event. The race was held on Sunday, October 6, 1991, before an audience of 159,000 in Concord, North Carolina, at Charlotte Motor Speedway, a 1.5 miles (2.4 km) permanent quad-oval. The race took the scheduled 334 laps to complete. Running on fumes, Junior Johnson & Associates driver Geoff Bodine would manage to run the final 76 laps of the race on one tank of fuel to take his 11th career NASCAR Winston Cup Series victory and his only victory of the season. To fill out the top three, Robert Yates Racing driver Davey Allison and owner-driver Alan Kulwicki would finish second and third, respectively.

With a poor finish from Dale Earnhardt's nearest competitor in the driver's championship standings, Ricky Rudd, Earnhardt was considered the favorite to win the driver's championship, having a 138-point lead over Rudd.

Qualifying
Qualifying was split into two rounds. The first round was originally scheduled to be held on Wednesday, October 2, at 5:00 PM EST, but was delayed to Thursday, October 3, at 8:30 AM EST due to rain. Each driver would have one lap to set a time. During the first round, the top 20 drivers in the round would be guaranteed a starting spot in the race. If a driver was not able to guarantee a spot in the first round, they had the option to scrub their time from the first round and try and run a faster lap time in a second round qualifying run, held on Thursday, October 3, at 1:30 PM EST. As with the first round, each driver would have one lap to set a time. For this specific race, positions 21-40 would be decided on time, and depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points; up to two were given. If needed, a past champion who did not qualify on either time or provisionals could use a champion's provisional, adding one more spot to the field.

Mark Martin, driving for Roush Racing, would win the pole, setting a time of 30.595 and an average speed of 176.499 mph in the first round.

Six drivers would fail to qualify.
