NASCAR has made a major change to the Sprint Cup Series Chase race at Auto Club Speedway.

The October competition at the Fontana race track will be 400 miles instead of 500 miles, the distance the race has been since 2003.

Auto Club Speedway has hosted two races in the NASCAR Sprint Cup Series since 2003. Both races have been 500 miles. Last year was the first time the second race at Fontana has been part of the Chase for the Sprint Cup, the 10-race playoff to determine the Cup champion.
