Auto Club Speedway - Cup Series Race Winners

Auto Club Speedway, also known as California Speedway, was a 2-mile (3.219 km), D-shaped oval superspeedway in San Bernardino County, California, near Fontana. It hosted National Association for Stock Car Auto Racing (NASCAR) racing annually from 1997 until 2023. It was also previously used for open wheel racing events. The racetrack was located 47 miles (76 km) east of Los Angeles and was near the former locations of Ontario Motor Speedway and Riverside International Raceway. The track was last owned and operated by NASCAR. In 2023, the track was closed for reconstruction as part of the Next Gen California racing project. Demolition began in October 2023. By 2025, 433 of the 522 acres of land used for the speedway had been sold to build warehouses and an industrial park. NASCAR hoped to use the remaining area under their control to build the new track, though commissioner Steve Phelps said in April 2025 that the project was on hold due to high construction expenses.
