With fewer than 80 laps remaining and after beginning the night from the rear of the field, Kyle Busch's No. 18 Toyota leads the Bank of America 500 at Charlotte Motor Speedway. Busch's team was forced to change engines earlier in the weekend, and per NASCAR rules that state that a team can only use one engine throughout the weekend, were forced for forfeit their qualifying position and drop to the tail end of the field.
Roush-Fenway drivers Matt Kenseth, Carl Edwards, and Greg Biffle run second through fourth. Biffle was dominant in the first half of the race before a lugnut miscue on a green-flag pit stop dropped him off the lead lap. Kasey Kahne rounds out the top-five.
David Ragan of Unadilla, in the fourth Roush-Fenway Ford, holds down sixth spot, followed by Marcos Ambrose, Denny Hamlin, A.J. Allmendinger, and Kevin Harvick.
Two drivers previously in the top-10 all night long who are now outside it are Tony Stewart and Trevor Bayne. Stewart had pitted from third position for a routine green-flag pit stop when Bayne's Ford ran out of fuel and stalled on the backstretch, drawing a caution flag. Stewart runs 13th, while Bayne is three laps down in the 32nd-position.
