The 1997 DieHard 500 was the 29th stock car race of the 1997 NASCAR Winston Cup Series and the 38th iteration of the event. The race was held on Sunday, October 12, 1997, in Lincoln, Alabama at Talladega Superspeedway, a 2.66 miles (4.28 km) permanent triangle-shaped superspeedway. The race took the scheduled 188 laps to complete. In the final three laps of the race, with help from brother Bobby Labonte, Hendrick Motorsports driver Terry Labonte would make a late-race charge through the field to take his 19th career NASCAR Winston Cup Series victory and his only victory of the season.^[1][2] To fill out the top three, the aforementioned Joe Gibbs Racing driver Bobby Labonte and Cale Yarborough Motorsports driver John Andretti would finish second and third, respectively.

Talladega Superspeedway, originally known as Alabama International Motor Superspeedway (AIMS), is a motorsports complex located north of Talladega, Alabama. It is located on the former Anniston Air Force Base in the small city of Lincoln. The track is a tri-oval and was constructed in the 1960s by the International Speedway Corporation, a business controlled by the France family. Talladega is most known for its steep banking and the unique location of the start/finish line that's located just past the exit to pit road. The track currently hosts the NASCAR series such as the NASCAR Cup Series, Xfinity Series and the Camping World Truck Series. Talladega is the longest NASCAR oval with a length of 2.66-mile-long (4.28 km) tri-oval like the Daytona International Speedway, which also is a 2.5-mile-long (4 km) tri-oval.

Qualifying was split into two rounds. The first round was held on Friday, October 10, at 3:00 PM EST. Each driver would have one lap to set a time. During the first round, the top 25 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 Saturday, October 11, at 10:45 AM EST. As with the first round, each driver would have one lap to set a time.^[3] Positions 26-38 would be decided on time, and depending on who needed it, the 39th thru either the 42nd, 43rd, or 44th position would be based on provisionals. Four spots are awarded by the use of provisionals based on owner's points. The fifth is awarded to a past champion who has not otherwise qualified for the race. If no past champion needs the provisional, the field would be limited to 42 cars. If a champion needed it, the field would expand to 43 cars. If the race was a companion race with the NASCAR Winston West Series, four spots would be determined by NASCAR Winston Cup Series provisionals, while the final two spots would be given to teams in the Winston West Series, leaving the field at 44 cars.

Ernie Irvan, driving for Robert Yates Racing, would win the pole, setting a time of 49.547 and an average speed of 193.271 miles per hour (311.040 km/h).^[4]

Five drivers would fail to qualify: Ward Burton, Hut Stricklin, Gary Bradberry, Jeff Green, and Ed Berrier.
