Auto Club Speedway

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. It is also used for open wheel racing events. The racetrack is located near the former locations of Ontario Motor Speedway and Riverside International Raceway. The track is owned and operated by International Speedway Corporation. The speedway is served by the nearby Interstate 10 and Interstate 15 freeways as well as a Metrolink station located behind the backstretch. Construction of the track, on the site of the former Kaiser Steel Mill, began in 1995 and was completed in late 1996. The speedway has a grandstand capacity of 68,000 and 28 skyboxes and a total capacity of 122,000. In 2006, a fanzone was added behind the main grandstand. Lights were added to the speedway in 2004 with the addition of a second annual NASCAR weekend. Since 2011, the track has hosted only one NASCAR weekend. IndyCar returned to the track in 2012 with its season finale race (a 500-mile night race); the series previously ran a 400-mile race from 2002 to 2005.
