After his qualifying run, Earnhardt, Jr. said, "We thought we had a top-five car in practice, and we got some good cloud cover about six or seven cars in front of us before we went to qualify, and that brought the track temp down to give us a good advantage," Earnhardt said. "It gave us a good opportunity to run a bit quicker lap than maybe what the car had in it." He was joined on the front row of the grid by Edwards. Johnson qualified third, Kyle Busch took fourth, and Marcos Ambrose started fifth. Denny Hamlin, Ryan Newman, Keselowski, Vickers, and Montoya completed the first ten positions on the grid.
