It is a four-turn rectangular-oval track that is 2.5 miles (4.023 km) long. The track's turns are banked at 9 degrees, while the front stretch, the location of the finish line, has no banking. The back stretch, opposite of the front, also has a zero degree banking. The racetrack has seats for more than 250,000 spectators.

Jeff Gordon became the first repeat winner, holding off Mark Martin for the win.^[2] Dale Jarrett dominated the second 100 miles of the race but lost his chance near the halfway point when he ran out of fuel, and coasted back to the pits; he lost four laps but made them up due to numerous cautions. Gordon's victory was the first in the Winston No Bull 5 program.
