I'm really happy. The process that's going to put us out front of Hendrick Motorsports and the guys at Joe Gibbs Racing and the rest of the guys we race against on Sunday, this process is just starting. We can use these positive things, like the pole position, hopefully a win, Greg [Biffle's] run last week, we can move forward. We've just got to keep moving forward. There's not a faster car in the place than our car today, and that's a big deal.”^[3] He was joined on the front row of the grid by Kurt Busch.^[14] Kasey Kahne qualified third, Paul Menard took fourth, and Aric Almirola ranked fifth.^[14] Joey Logano, Austin Dillon, Matt Kenseth, Kyle Busch, and Juan Pablo Montoya completed the first ten positions on the grid.^[14] The driver who failed to qualify for the race was Scott Riggs.^[3]

Race

The race began with Kurt Busch colliding with pole-sitter Carl Edwards in turn 2 on the opening lap in an attempt to grab the lead. Edwards lost multiple positions as a result, and Kurt Busch emerged in front. The first caution flew on lap 6, after Bobby Labonte got loose and spun in turn 2, collecting Jeff Gordon. A competition caution was thrown on lap 20 for the previous night's rain. Kurt Busch lost the lead to Joey Logano during this caution, and only three laps after the subsequent restart, on lap 29, Busch got loose off of turn two and crashed down the back-straightaway.

Afterward, multiple caution flags and different pit stop strategies gave Joey Logano, Jamie McMurray, Jimmie Johnson, Dale Earnhardt Jr., and Kasey Kahne turns at leading the race. At one point, Johnson rebounded to the second position after falling to twelfth as a result of a mistake made on a restart. On lap 104 and while leading the race, Kahne experienced a right-front tire failure and crashed into the outside wall in turn 1, setting his car ablaze and eliminating him from the event. Fortunately, Kahne was not harmed by the impact or the fire. Johnson took over the lead but lost it to Earnhardt during pit stops. On the restart on lap 113, Earnhardt began to pull away from Kenseth and Biffle as Johnson struggled to battle back to the front. Several laps later, Earnhardt developed engine problems and fell off the pace, giving Johnson (who had successfully passed Kenseth and Biffle) the lead. After a few slow laps, Earnhardt's engine blew up, bringing out another caution on lap 131. After taking four tires in the pits, Johnson fell to 20th and Edwards took the lead ahead of Logano, Kenseth, and Biffle.

Following the restart on lap 136, Biffle worked his way past both Kenseth and Logano into second and proceeded to chase down Edwards, passing him for the lead on lap 150 and quickly pulling away afterward. A caution for a right-front tire failure on the car of McMurray occurred in the middle of the last round of pit stops, trapping Edwards a lap down (although he would immediately receive the free pass). Biffle, who had pitted under the green but did not go a lap down, cycled out as the leader. On the lap of the restart (lap 174), Kenseth got loose off of turn two, causing him to drop several positions while Johnson, who restarted tenth, began to pass cars. Johnson gradually worked his way through the field, eventually passing Harvick to move into second with eight laps to go. However, as Johnson struggled to catch Biffle, he experienced a right-front tire failure off of turn 2 on lap 198, causing him to make contact with the outside wall and relegating him to a 28th-place finish after having to pit to address the tire. Biffle sped away to take the victory over Harvick, Martin Truex Jr., Kyle Busch, and Tony Stewart. Biffle's win was the 615th race victory for the Ford marque and 715th for Ford Motor Company in the Cup Series. It was also the 1,000th race victory for Ford Motor Company in NASCAR's three national touring series.^[17][18]
