1997 MBNA 400

The 1997 MBNA 400 was the 26th stock car race of the 1997 NASCAR Winston Cup Series and the 29th iteration of the event. The race was held on Sunday, September 21, 1997, in Dover, Delaware at Dover International Speedway, a 1-mile (1.6 km) permanent oval-shaped racetrack. The race took the scheduled 400 laps to complete. Depending on fuel mileage, Roush Racing driver Mark Martin would manage to save enough fuel to secure his 22nd career NASCAR Winston Cup Series victory and his fourth and final victory of the season. To fill out the top three, Richard Childress Racing driver Dale Earnhardt and Petty Enterprises driver Kyle Petty would finish second and third, respectively.

Background
Dover International Speedway is an oval race track in Dover, Delaware, United States that has held at least two NASCAR races since it opened in 1969. In addition to NASCAR, the track also hosted USAC and the NTT IndyCar Series. The track features one layout, a 1-mile (1.6 km) concrete oval, with 24° banking in the turns and 9° banking on the straights. The speedway is owned and operated by Dover Motorsports.

The track, nicknamed "The Monster Mile", was built in 1969 by Melvin Joseph of Melvin L. Joseph Construction Company, Inc., with an asphalt surface, but was replaced with concrete in 1995. Six years later in 2001, the track's capacity moved to 135,000 seats, making the track have the largest capacity of sports venue in the mid-Atlantic. In 2002, the name changed to Dover International Speedway from Dover Downs International Speedway after Dover Downs Gaming and Entertainment split, making Dover Motorsports. From 2007 to 2009, the speedway worked on an improvement project called "The Monster Makeover", which expanded facilities at the track and beautified the track. After the 2014 season, the track's capacity was reduced to 95,500 seats.

Qualifying
Qualifying was split into two rounds. The first round was held on Friday, September 19, 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, September 20, at 11:30 AM EST. As with the first round, each driver would have one lap to set a time. 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.

Mark Martin, driving for Roush Racing, would win the pole, setting a time of 23.679 and an average speed of 152.033 mph.

Steve Park was the only driver to fail to qualify.
