Auto Club Speedway » Wiki (Topic)

California Speedway (known as Auto Club Speedway from 2008–2023 due to corporate sponsorship by the Automobile Club of Southern California) was a 2.000 mi (3.219 km), D-shaped oval superspeedway in unincorporated 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 mi (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. The speedway was served by the nearby Interstates 10 and 15 as well as a Metrolink station located behind the backstretch.
