1989 AC Delco 500

The 1989 AC Delco 500 was the 27th stock car race of the 1989 NASCAR Winston Cup Series season and the 25th iteration of the event. The race was held on Sunday, October 22, 1989, before an audience of 52,500 in Rockingham, North Carolina, at North Carolina Speedway, a 1.017 mi permanent high-banked racetrack. At race's end, Roush Racing driver Mark Martin would manage to dominate the late stages of the race, leading the final 77 laps to take his first career NASCAR Winston Cup Series victory and his only victory of the season. To fill out the top three, Blue Max Racing driver Rusty Wallace and Hendrick Motorsports driver Darrell Waltrip would finish second and third, respectively.

Background
North Carolina Motor Speedway was opened as a flat, one-mile oval on October 31, 1965. In 1969, the track was extensively reconfigured to a high-banked, D-shaped oval just over one mile in length. In 1997, North Carolina Motor Speedway merged with Penske Motorsports, and was renamed North Carolina Speedway. Shortly thereafter, the infield was reconfigured, and competition on the infield road course, mostly by the SCCA, was discontinued. Currently, the track is home to the Fast Track High Performance Driving School.

Qualifying
Qualifying was split into two rounds. The first round was held on Thursday, October 19, at 2:30 PM EST. 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 Friday, October 20, at 2:00 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.

Alan Kulwicki, driving for his own AK Racing team, would win the pole, setting a time of 24.634 and an average speed of 148.624 mph in the first round.

No drivers would fail to qualify.
