Background

Daytona International Speedway, where the race was held.

Daytona International Speedway is one of six superspeedways to hold NASCAR races, the others being Michigan International Speedway, Auto Club Speedway, Indianapolis Motor Speedway, Pocono Raceway and Talladega Superspeedway.^[5] The standard track at Daytona International Speedway is a four-turn superspeedway that is 2.5 miles (4.0 km) long.^[6] The track's turns are banked at 31 degrees, while the front stretch, the location of the finish line, is banked at 18 degrees.^[6] David Ragan is the defending race winner.^[7]

Before the race, Matt Kenseth led the Drivers' Championship with 633 points, and Dale Earnhardt Jr. stood in second with 622. Jimmie Johnson was third in the Drivers' Championship with 610, two points ahead of Greg Biffle and thirty-four ahead of Denny Hamlin in fourth and fifth. Kevin Harvick, with 565, was eight points ahead of Clint Bowyer, as Martin Truex Jr. with 556 points, was eleven ahead of Tony Stewart and nineteen in front of Brad Keselowski.^[8] In the Manufacturers' Championship, Chevrolet was leading with 117 points, seventeen points ahead of Toyota.

Practice and qualifying

Two practice sessions were also held before the race on July 5, 2012. The first session was 80 minutes long, while the second was 85 minutes.^[10] Aric Almirola was quickest with a time of 44.563 seconds in the first session, 0.130 faster than Marcos Ambrose.^[11] Joey Logano was third quickest, followed by Ryan Newman, Biffle, and Jeff Gordon. A. J. Allmendinger was seventh, still within half of a second of Almirola's time.^[11] In the second and final practice session, Jamie McMurray was quickest with a time of 45.492 seconds.^[12] Michael Waltrip, with a time of 45.516, was second quickest, ahead of Kurt Busch, Travis Kvapil, and Almirola.^[12] Regan Smith, Ambrose, Carl Edwards, Earnhardt Jr., and Juan Pablo Montoya completed the first ten positions.^[12]

Forty-four cars were entered for qualifying, but only forty-three could qualify for the race because of NASCAR's qualifying procedure.^[13] Kenseth clinched the eighth pole position of his career, with time of 46.781 seconds.^[14] He was joined on the front row of the grid by Stewart.^[14] Newman qualified third, Kasey Kahne took fourth, and Biffle started fifth.^[14] Gordon, Bill Elliott, Casey Mears, Allmendinger and Keselowski rounded out the top ten. The driver that failed to qualify for the race was Robert Richardson Jr.^[14] Once the qualifying session had concluded, Kenseth stated, "The interesting thing about qualifying, at least for me today, was nobody had any idea what the pole was going to be or how fast anybody was. They lined qualifying up by first practice speeds, but that was drafting for everybody. So, you really didn't know what anybody was going to run. That's the same lap we ran during a mock-up qualifying run [Friday], so I was glad we were able to repeat that, but I didn't know what anybody else was going to run. It's kind of fun to watch, because you really have no idea."^[15]

Prior to the race

Tony Stewart was stripped of his second place starting spot after his car failed post-qualifying inspection. A. J. Allmendinger was suspended by NASCAR after failing a drug test. Penske Racing scrambled to get Sam Hornish Jr. in the #22 and had Kenny Wallace (who himself was on standby for expectant father Kevin Harvick after NASCAR would not approve Austin Dillon for Sprint Cup competition at Daytona) ready to step in if Hornish couldn't make it to Daytona on time. Michael McDowell got into the #98 Phil Parsons Racing entry that Mike Bliss qualified.

Final laps

With 16 laps to go, the 4th caution flew when Brad Keselowski spun off of turn 2. The race restarted with 12 to go. With 9 to go, Matt Kenseth took the lead from Stewart. With 8 to go, the second big one struck on the front stretch near turn 1 collecting 14 cars. It started when Denny Hamlin got turned by Kyle Busch and Hamlin came up and collected Busch, Juan Pablo Montoya, Trevor Bayne, Marcos Ambrose, Clint Bowyer, Jeff Gordon, David Reutimann, Dave Blaney, David Gilliland, Casey Mears, Paul Menard, David Ragan, and Martin Truex Jr. The wreck would set up a two lap shootout. Kenseth took the lead on the restart and began to battle Stewart for the lead. On the last lap, Stewart lost his drafting partner Kasey Kahne but Stewart kept on going and took the lead from Kenseth. Kenseth tried to get to Stewart's outside but contact between Matt Kenseth and Greg Biffle sent Biffle into Kevin Harvick and caused a 15 car crash that also collected Aric Almirola, Dave Blaney, Kyle Busch, David Ragan, Kasey Kahne, Travis Kvapil, Dale Earnhardt Jr, Regan Smith, Carl Edwards, Paul Menard, Terry Labonte, and Jamie McMurray. It brought out the 6th and final caution of the race and Tony Stewart won the race. This would be Stewart's 4th and final Coke Zero 400 win of his career along with his 3rd and final win of 2012. Jeff Burton, Matt Kenseth, Joey Logano, and Ryan Newman rounded out the top 5 while Carl Edwards, Kasey Kahne, Brad Keselowski, Michael Waltrip, and Bobby Labonte rounded out the top 10.^[17]
