Two practice sessions are scheduled to be held in preparation for the race; one on August 19, 2011 and the other on the following day. The first session was 90 minutes long, while the second will be 110 minutes long.[10] During the first practice session, Matt Kenseth, for the Roush Fenway Racing team, was quickest ahead of Ryan Newman in second and Greg Biffle in the third position.[11] Mark Martin was scored fourth and David Ragan managed fifth.[11] Paul Menard, Jeff Gordon, Jamie McMurray, Brad Keselowski, and Marcos Ambrose rounded out the top ten quickest drivers in the session.[11]

Forty-six cars were entered for qualifying, but only forty-three could qualify for the race because of NASCAR's qualifying procedure. Biffle clinched the sixth pole position of his career, with a time of 37.826 seconds.[12][13] He was joined on the front row of the grid by Kenseth.[13] Newman qualified third, Denny Hamlin took fourth, and Martin started fifth.[13] Keselowski, Ragan, Dale Earnhardt, Jr., Gordon and McMurray rounded out the top ten.[13] The drivers that failed to qualify for the race were Johnny Sauter, Erik Darnell and T. J. Bell.[13] Following the qualifying session, Biffle commented, "We didn't know whether we were going to come here in race or qualifying trim. But we worked on a great qualifying set-up and obviously had good speed today. We'll work on things tomorrow on practice and hopefully have a great car on Sunday."[3]

In the second and final practice, Martin was quickest with a time of 38.371 seconds. Kyle Busch followed in second, ahead of Johnson and Biffle. Gordon was fifth quickest, with a time of 38.452 seconds. Kurt Busch, Kenseth, Newman, Ragan, and Menard rounded out the first ten positions.[14] Afterward, Martin discussed his feelings about the track, "I really, really like running at Michigan, not just because it's so fast, but it's so wide. We can race all over the track. I've been lucky at Michigan, and I've been just plain good. I've gotten a lot of wins there. Last time we raced there, we were pretty good. ... We've got to build on what we learned in that race and try to do even better this time around."[15]
