The race was the first of the season to remove roof cameras to lessen turbulent air impact, and will be removed for two-thirds of the points races.^[8]

Three practice sessions were held before the race on March 1 and March 2, 2013. The first session lasted 85 minutes long, while the second was 55 minutes long. The third session lasted for 50 minutes.^[9] Matt Kenseth was quickest with a speed of 137.023 miles per hour (220.517 km/h) in the first session, 0.047 miles per hour (0.076 km/h) faster than Kyle Busch.^[10] Martin was just off Kyle Busch's pace, followed by Hamlin, Carl Edwards, and Johnson. The session was paused temporarily after debris prompted a caution.^[10]

Forty-three cars were entered for the qualifying session held on March 1.^[11] Martin clinched his fifty-sixth pole position of his career, with a time of 26.073 seconds, which was a new race record.^[12][13] He was joined on the front row of the grid by Kasey Kahne.^[13] Johnson qualified third, Kyle Busch took fourth, and Gordon started fifth.^[13] Tony Stewart, Kevin Harvick, Hamlin, Kenseth, and Newman rounded out the first ten positions.^[13]

On March 7, NASCAR fined Denny Hamlin $25,000 for saying that the then-new Gen 6 cars did not race as well as the previous-generation car, citing difficulty passing.^[14] Because Hamlin publicly refused to pay the fine, NASCAR instead took $25,000 off his race winnings instead.^[15]
