Auto Club 500
The 2008 Auto Club 500 was run on February 24 and February 25 due to rain at the newly renamed Auto Club Speedway of Southern California (previously California Speedway) in Fontana, California. Qualifying was canceled for the Sprint Cup, Nationwide and Craftsman Truck Series after periods of rain showers fell for most of the day on Friday. As a result, the race lineup was determined by the NASCAR rule book. The race began on late Sunday afternoon but was red flagged and eventually postponed until Monday morning. Veteran NASCAR driver Mark Martin made his 700th Sprint Cup Series start. The first caution of the race was brought out when Denny Hamlin lost control in Turn 3 after running over some water that had seeped up through cracks in the track surface. The next caution involved a large wreck when Casey Mears spun out in Turn 2 after also running over water. The wreck collected Casey's teammate Dale Earnhardt, Jr..
Reed Sorenson and Sam Hornish, Jr. were also involved. Hornish hit Sorenson's car causing his car's hood to come up and hit his windshield obscuring his vision leading him to rear end the back of Casey Mears' car causing Mears' car to tumble onto its side. The race was red flagged as track workers cleaned up and tried to repair the water problem by cutting into the track. Drivers who were involved in early wrecks notably Earnhardt, Jr. and Mears complained that NASCAR should not have started the race with water still seeping onto the track. Eventually a seventh caution for rain put the race on hold, at 11:00 PM PT (2:00 AM ET), NASCAR decided to postpone the remaining race laps until Monday morning at 10:00 AM PT (1:00 PM ET) due to seeping water on the track. When the race resumed, it was Hendrick Motorsports teammates Jeff Gordon and Jimmie Johnson leading the race until Carl Edwards took the lead from Johnson to win his first race at Auto Club Speedway. The Nationwide Series race was run one hour after the conclusion of the Sprint Cup race.
