During the pace laps, three drivers moved to the rear of the field because of unapproved changes; Bowyer had switched to his back-up car, and David Ragan and Harvick had changed their engines. The race began at 5:52p.m. Newman maintained his pole-position advantage heading into the first corner. After starting 21st, Jimmie Johnson moved to 15th position by lap eight. Kurt Busch passed teammate Newman for the lead three laps later. By the 20th lap, Kurt Busch, Newman, Earnhardt, Kenseth and Yeley were running in the top five positions. Earnhardt got ahead of Newman for second place four laps later. Hamlin moved to third position by lap 32. Hamlin made up a further position on lap 43 after he passed Earnhardt for second and was 1.2 seconds behind race leader Kurt Busch. The first caution of the race was shown four laps later when Biffle hit the turn two wall after his right-front tire had been cut and dropped debris on the track. Biffle's car sustained heavy damage to the right-hand side, ending his race. All drivers elected to make pit stops for tires and fuel during the caution. Kurt Busch, who made a 10.4-second pit stop for fuel and no tires, maintained the lead on the lap-52 restart ahead of Hamlin, Kenseth, Earnhardt and Johnson. One lap later, a multi-car collision occurred on the front stretch when A. J. Allmendinger lost control of his car in turn two and collided with the right-rear quarter panel of Johnson's car, which had a cut left-rear tire that burst after leaving turn four. Johnson's burst tire caused Blaney and Stewart to collide after Stewart slowed to avoid a collision with Johnson. Both drivers slid, collecting Gilliland, Sadler, Juan Pablo Montoya, Green, Bowyer, Truex, Marlin, Johnny Sauter, Kyle Petty and Harvick, all of whom had damage to their cars. The incident triggered the race's second caution. Johnson and Stewart made pit stops to repair the damage to their cars; both rejoined the race in eighteenth and twenty-fifth positions. Kurt Busch led on the lap-62 restart, ahead of Hamlin, Kenseth, Earnhardt, and Gordon. The third caution was prompted on the same lap when Tony Raines lost control of his car and slid sideways into Jeff Gordon, and both drivers were sent into the infield grass. Jeff Gordon went back up towards a right-hand wall and was hit by Allmendinger at the start-finish line, resulting
