Auto Club Speedway officials announced Tuesday the change of the Auto Club 500 to the Auto Club 400. The 400-mile event will run on Sunday, March 27, 2011.

Last October's 400-miler at the California track produced great racing with Tony Stewart taking the win 0.466 seconds ahead of Clint Bowyer, one of the closest finishes in the track's history.

"The restarts early in the race were out of control. We were five wide," commented Stewart.

Many hardcore race fans called it "the best race ever at Auto Club Speedway."

"It's impossible to ignore the on track excitement we experienced at Auto Club Speedway in October, as a result of NASCAR reducing the Chase race from 500 to 400 miles," said ACS President Gillian Zucker. "We're confident the newly remileaged Auto Club 400 will continue the momentum we have been experiencing and that March's race will be the most exciting ever at Auto Club Speedway."
