SAN BERNARDINO COUNTY, Calif. (Jan. 11, 2011) – NASCAR continues to listen and respond to its fans and as a result, they will be the beneficiary of more exciting NASCAR Sprint Cup racing when it comes to Southern California in March.

Changing the mileage from 500 to 400 for Auto Club Speedway’s October event along with double file restarts resulted in an action-packed three hours that media, drivers and fans called “the best race ever at Auto Club Speedway.” With that feedback, ACS officials announced today that the Auto Club 500 will now be the Auto Club 400. The race will take place on Sunday, March 27 beginning at noon (PT) on FOX.
