The Auto Club 400 is a 400 miles (643.737 km) long NASCAR Sprint Cup Series stock car race held at the Auto Club Speedway in Fontana, California. Prior to 2005, the race was held in late April or early May, and until 2010, the race was run at a length of 500 miles. When the NASCAR Realignment of 2005 was made, the race was moved to February. The February date stayed until the 2011 season when the date changed to March. After being pleased with the results of the reduction of the track's former fall race date, the Pepsi Max 400, from 500 to 400 miles Auto Club Speedway decided to do the same thing to its spring race.

- 1997: After nearly a decade, NASCAR came back to Southern California on June 22 with the inaugural California 500. The race featured 21 lead changes among a dozen different drivers. Jeff Gordon passed Mark Martin with 11 laps remaining and sped to victory. Terry Labonte took second, giving Hendrick Motorsports another 1-2 finish.
- 2008: The Race started on Sunday, Running for 87 laps with 7 yellow flags and 2 red flags. NASCAR Chose to Postpone the event to Monday due to a lengthy red flag. The rain delay on Sunday also delayed the Stater Brothers 300 (Now Royal Purple 300) to Monday. Carl Edwards would go on to win the event, while he finished 5th in the Nationwide Event.
- 2013: Kyle Busch won after Joey Logano and Denny Hamlin crashed fighting hard for the lead on the last lap. Busch also took the weekend sweep by winning the Nationwide race the day before. It is the first Fontana victory in the Sprint Cup Series both for Joe Gibbs Racing and Toyota. Interesting note is that from 2011-2013 Busch finished in a reverse type of order: 3rd (In 2011), 2nd (2012) and 1st (In 2013). The last lap crash between Logano and Hamlin sent Hamlin into the inside wall (without a SAFER Barrier) head-on. As a result he suffered a compression fracture of his L1 vertebra in his back, which sidelined him for the next six weeks.
