EchoPark Speedway (commonly referred to as Atlanta Motor Speedway) is a 1.54-mile race track in Hampton, Georgia, United States, 20 miles (32 km) south of Atlanta. It has annually hosted NASCAR Xfinity Series stock car races since 1992.
The venue was bought by Speedway Motorsports in 1990. In 1994, 46 condominiums were built over the northeastern side of the track. In 1997, to standardize the track with Speedway Motorsports' other two intermediate 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, with a new official length of where before it was . The project made the track one of the fastest on the NASCAR circuit. In July 2021 NASCAR announced that the track would be reprofiled for the 2022 season to have 28 degrees of banking and would be narrowed from 55 to 40 feet which the track claims will turn racing at the track similar to restrictor plate superspeedways. Despite the reprofiling being criticized by drivers, construction began in August 2021 and wrapped up in December 2021. The track has seating capacity of 71,000 to 125,000 people depending on the tracks configuration.
On June 3, 2025, SMI announced the track's renaming to EchoPark Speedway under a new seven-year sponsorship deal with the Smith family-owned business, EchoPark. The renaming ended a 35-year stint under the Atlanta Motor Speedway name.
On August 20, 2025, when the schedule was unveiled, Autotrader was announced as the title sponsor for EchoPark's spring race, replacing Ambetter Health.
Qualifying for the race was canceled due to inclement weather. Tyler Reddick was awarded the pole for the race as a result of NASCAR's pandemic formula with a score of 1.000.
