The 2021 Quaker State 400 was a NASCAR Cup Seriesrace held on July 11, 2021, at Atlanta Motor Speedway in Hampton, Georgia. Contested over 260 laps on the 1.54-mile-long (2.48 km) asphalt quad-oval intermediate speedway, it was the 21st race of the 2021 NASCAR Cup Series season. Kurt Busch, driving the No. 1 car for Chip Ganassi Racing, held off his younger brother Kyle to secure what would ultimately be CGR's final win in NASCAR. This was also the last race held at the track before it was re-configured into a superspeedway in 2022.
Atlanta Motor Speedway (formerly Atlanta International Raceway) is a track in Hampton, Georgia, 20 miles (32 km) south of Atlanta. It is a 1.54-mile (2.48 km) quad-oval track with a seating capacity of 111,000. It opened in 1960 as a 1.5-mile (2.4 km) standard oval. In 1994, 46 condominiums were built over the northeastern side of the track. In 1997, to standardize the track with Speedway Motorsports' other two 1.5-mile (2.4 km) ovals, the entire track was almost completely rebuilt. The frontstretch and backstretch were swapped, and the configuration of the track was changed from oval to quad-oval. The project made the track one of the fastest on the NASCAR circuit.
