Auto Club Speedway (formerly California Speedway) is a two-mile (3 km), low-banked, D-shaped oval superspeedway in Fontana, California which has hosted NASCAR racing annually since 1997. The track was also used for open wheel racing events until 2005. The racetrack is located near the former locations of Ontario Motor Speedway and Riverside International Raceway. The track is currently owned and operated by International Speedway Corporation and is the only track owned by ISC to have naming rights sold. The speedway is served by the nearby Interstate 10 and Interstate 15 freeways as well as a Metrolink station located behind the backstretch. - Source: Wikipedia
