Harvick won the pole with a time of 22.095 and a speed of 162.933 mph (262.215 km/h). "It’s been an amazing year for everybody," Harvick said of his team. "They do a great job in preparing the racecars and put a lot of effort into qualifying, and it’s translated into a lot of good finishes." "This is the most important race of my career," Hamlin said. "This is the most important race now because it's in the present. If we’re going to live to race another day, we’ve got to get past this weekend. If not, we become somewhat irrelevant."^[19] Forty-three cars were entered so no one failed to qualify.

Jeff Gordon cycled back to the lead and kept it to score his 92nd career win. “I knew we could compete with the 2 car [Keselowski],” Gordon said. “The 2 was really good on short runs but we could run them down. He made us work for it there at the end... He got to me and I was really, really tight in traffic there at the end, so I didn't know if we were gonna pull it off.” Kevin Harvick, who led a race high 223 laps before cutting a left-front tire, finished 13th one lap down. "I don't know what happened to Kevin Harvick," Gordon said. "That was unfortunate for him. He was the class of the field. ... I was really tight in traffic there at the end. I didn't know if we were going to pull it off." "We can beat every car on the race track. We just need some good luck," Harvick adds. "We'll win races and have a shot at the championship."^[25] Kasey Kahne secured the twelfth and final spot in the points to advance to the Contender Round. “I had to push hard,” Kahne said. “I'm glad NASCAR just let us go and let us race for it. It was pretty interesting, but I'm glad we made it. We had to fight hard, and I think we had a Top-2 or 3 car today – just didn't get to show it.” With this being the final race of the Challenger Round, A. J. Allmendinger, Kurt Busch, Greg Biffle and Aric Almirola were the bottom four drivers in points that were eliminated.^[26]
