Background

The 2012 Quicken Loans 400 was the 15th of 36 scheduled stock car races of the 2012 NASCAR Sprint Cup Series. It ran for 200 laps over a distance of , and was held on June 17, 2012, in Brooklyn, Michigan, at Michigan International Speedway, a superspeedway that holds NASCAR races. The standard track at Michigan International Speedway is a four-turn superspeedway. The track's turns are banked at eighteen degrees, while the front stretch (the location of the finish line) is banked at twelve degrees. The back stretch, has a five degree banking.

In preparation for the race, NASCAR held two test sessions on June 12, 2012, for teams to test the newer pavement at Michigan, the first since 1995. During the first test session (which was held in the morning and lasted for four hours) Mark Martin was quickest ahead of Kevin Harvick with a speed of and a time of 35.805 seconds, while Tony Stewart was fastest in the second and final test session with a time of 35.662 seconds and recorded a speed of . Top speeds approached during the day; NASCAR determined that the installation of restrictor plates would not be required, and NASCAR vice-president of competition Robin Pemberton spoke of his expectation that speeds would reduce as the surface rubbered in and track temperatures increased.

Before the race, Matt Kenseth led the Drivers' Championship with 523 points, and Dale Earnhardt Jr. stood in second with 513 points. Greg Biffle was in third place on 507 points, three points ahead of Denny Hamlin in fourth and fourteen points in front of Jimmie Johnson in fifth. Harvick, with 470 points, was five points in front of Martin Truex Jr., as Stewart with 448 points, was five points in front of Clint Bowyer in ninth and eight points in front of the tenth-placed Brad Keselowski. Carl Edwards and Kyle Busch rounded out the top twelve drivers. In the Manufacturers' Championship, Chevrolet was leading with 96 points, thirteen points ahead of Toyota in the second position. Ford, with 71 points, was also thirteen points ahead of Dodge in the battle for third place. Hamlin was the race's defending champion.

There were two driver changes heading into the race. After he was suspended from the preceding Pocono 400 for verbally abusing The Sporting News reporter Bob Pockrass at the Nationwide Series round at Dover International Speedway, Kurt Busch was reinstated to the 51 Phoenix Racing car after David Reutimann drove in his place. Team owner James Finch spoke to Busch during the week, and confirmed that the driver would remain with the team until the end of the year. Tommy Baldwin Racing announced that driver Tony Raines would compete in its No. 10 car in place of Reutimann as part of the team's plan for the upcoming races.

Practice and qualifying Three practice sessions were held before the Sunday race. The first and second sessions that took place on Friday ran for 80 minutes, and the third additional practice session held on Saturday lasted 75 minutes. In the first practice session, Martin was fastest with a lap of 35.754 seconds, almost six hundredths of a second faster than Earnhardt in second. Trevor Bayne, Stewart, Kenseth, Juan Pablo Montoya, Jeff Gordon, Kasey Kahne, Paul Menard, and Truex followed in positions three to ten. Biffle paced the second practice session with a 35.172 seconds lap. He was six hundredths of a second faster than Marcos Ambrose in the second position. Harvick, Edwards, Menard, Bayne, Johnson, Joey Logano, Kurt Busch, and Kenseth completed the top ten ahead of the qualifying session. The only incident in the Friday practice sessions was Jamie McMurray scraping the right-hand quarter of his vehicle when he made contact with the outside barrier.

Early average practice speeds approached , breaking the official qualifying stock car speed record of . Blisters appeared on several front-side tires used by an estimated one-quarter of teams during the session, and that caused drivers to raise concerns about the speed they were driving at on the warm track surface and the hot weather temperatures that were experienced in the opening two practice sessions. Harvick suggested that all the drivers slow to manage the wear of their tires when the track surface rubbered in, while Edwards and Hamlin reported no issues with their tires; the former said he would discuss the situation with his crew chief Bob Osborne. NASCAR's control tire supplier Goodyear advised all teams to scuff their tires, and run them through a heat cycle. The tires run in practice were later utilized in the Saturday morning qualifying session.

Forty-five drivers were entered in the qualifier on Saturday afternoon, according to NASCAR's qualifying procedure, 43 were allowed to race. Each driver was limited to two timed laps, with the starting order determined by the competitor's fastest times. Recording a track speed record of that broke's Ryan Newman's achievement in June 2005, Ambrose clinched the first pole position of his career with a time of 35.426 seconds. He was the fourth driver to complete a qualifying lap that was faster than , and it was the fastest speed set in any qualifier since Bill Elliott's 1987 Talladega Superspeedway lap. He was joined on the grid's front row by Harvick who was 0.211 seconds slower, and held the pole until Ambrose's lap. Biffle qualified third, Kahne took fourth, and Newman started fifth. Kenseth, Bayne, Stewart, Logano, and Johnson rounded out the top ten qualifiers. Edwards' engine developed a possible fuel related issue on his warm-up lap, and he did not set a timed effort. The two drivers who failed to qualify were David Stremme and Stacy Compton. After qualifying, Ambrose said, "It is a good bragging right, I'll give it that, I'm just really excited to get the speed, and to claim to be the fastest guy out there is just awesome. We've missed some poles — this is my first pole in Sprint Cup. We've missed some by thousandths of a second and conditions changing, so it's good that we actually got one to stick, and one that's got so many records attached to it."

After qualifying, Goodyear changed the left-hand side tire combination to a more durable and harder compound after consulting teams and analysing data, but retained the original right-hand side compound. They transported 1,200 tires from a warehouse in North Carolina to ensure each team met NASCAR's requirement of using 10 sets of tires for the event, and they arrived in Michigan on Saturday afternoon. An extra 75 minute practice session was scheduled following the track's Nationwide Series race. Biffle was quickest with a lap of 36.801 seconds, followed by Johnson, Edwards, Kahne, McMurray, Kurt Busch, A. J. Allmendinger, Truex, Martin, and Harvick. Top speeds approached no higher than , but the new left-hand side tires received a mixed reception from drivers. Newman felt that NASCAR made the correct decision, and Edwards predicted that the while the cars were looser, it would improve the quality of racing. Earnhardt, however, commented that he could not complete extra laps due to a handling difficulty, and Ambrose noted a lower amount of grip and increased vehicular imbalance provided by the tires.
