2015 Quicken Loans 400

Michigan International Speedway, the track where the race was held.

Michigan International Speedway (MIS) is a two-mile (3.2 km) moderate-banked D-shaped speedway located off U.S. Freeway 12 on more than 1,400 acres (5.7 km²)[13] approximately four-mile (6.4 km) south of the village of Brooklyn, in the scenic Irish Hills area of southeastern Michigan. The track is used primarily for NASCAR events. It is sometimes known as a "sister track" to Texas World Speedway, and was used as the basis of Auto Club Speedway. The track is owned by International Speedway Corporation (ISC). Michigan International Speedway is recognized as one of motorsports' premier facilities because of its wide racing surface and high banking (by open-wheel standards; the 18-degree banking is modest by stock car standards). Michigan is the fastest track in NASCAR due to its wide, sweeping corners and long straightaways; typical qualifying speeds are in excess of 200 MPH (320 km/h) and corner entry speeds are anywhere from 215 to 220 mph (346 to 354 km/h) after the 2012 repaving of the track.

Kevin Harvick entered Michigan with a 39-point lead over Martin Truex Jr. following a runner-up finish at Pocono to Truex. Jimmie Johnson entered 78 back. Joey Logano entered 79 back. Dale Earnhardt Jr. entered 94 back.

The entry list for the Quicken Loans 400 was released on Tuesday, June 9 at 9:09 a.m. Eastern time. Forty-four cars were entered for the race. All but the No. 21 Wood Brothers Racing Ford driven by Ryan Blaney were entered the week before at Pocono. The only driver swap for this race is the No. 32 Go FAS Racing Ford that was driven by Mike Bliss.

Kevin Harvick was the fastest in the second practice session with a time of 35.806 and a speed of 201.084 mph (323.613 km/h).[20]

Jeff Gordon was the fastest in the final practice session with a time of 36.253 and a speed of 198.604 mph (319.622 km/h).[21] Halfway through the session, Denny Hamlin spun out on the front stretch and caused minor damage to the front splitter.[21] The team initially decided to roll out the backup car, but chose to fix the primary car rather than starting from the rear of the race.[21]

The race was scheduled to start at 1:16 p.m., but the threat of thunderstorms prompted NASCAR to move the start time up ten minutes. Eventually, the race started eight minutes after one. Kasey Kahne led the field to the green flag, but lost the lead to Carl Edwards on the first lap. He passed him to lead the second lap. Edwards went by him again to lead the third lap. The first caution of the race flew on lap 11 for rain in turns 1 and 2. The race was red flagged on lap 13 for rain.[22] After 59 minutes, the red flag was lifted and the field was moved off pit road. After two laps under caution, rain began to fall again in turn 1. The rain started coming down harder all around the track and the field was brought back down pit road again. The race was red flagged a second time on lap 19. It was lifted after 34 minutes.[23]

The race was set to restart on lap 25, but it was called off after Alex Bowman – who made contact with the wall early in the race – left debris on the backstretch. Eventually, the race restarted on lap 29. The second caution of the race flew on lap 41. It was a scheduled competition caution due to overnight rain. Josh Wise opted not to pit and took the lead. He drove down pit road the next lap and handed the lead to Kevin Harvick. Just as the field was lining up for the restart on lap 44, rain began to pour a third time. The field was brought back down pit road and the race was red flagged for the third time. After 36 minutes, the red flag was lifted and the field rolled off pit road.[23]

The race restarted on lap 52. The third caution of the race flew on lap 53 for a single car wreck on the front stretch. Exiting turn 4, Kyle Busch's car snapped loose, turned up the track and pounded the wall.[24] The SAFER barrier he hit was damaged and required repair.[23]

The race restarted on lap 60. A number of cars began hitting pit road around lap 77. Kevin Harvick surrendered the lead to pit on lap 83 and handed the lead to Matt Kenseth. He pitted on lap 85 and handed the lead to Brad Keselowski. He ducked onto pit road the next lap and gave the lead to Kyle Larson. He pitted on lap 88 and handed the lead to Joey Logano. He ran out of fuel on lap 95 and hit pit road. This gave the lead to Danica Patrick. She pitted on lap 97 and the lead cycled back to teammate Harvick.[25]

Harvick gave up the lead to pit on lap 121 and handed it to Dale Earnhardt Jr. He pitted the next lap and it went to Kenseth. He pitted the next lap and handed it to Keselowski. Harvick stopped a second time for a flat right-front tire. Debris in turn 3 brought out the fourth caution of the race on lap 125. That debris came from Harvick's car. Edwards opted not to pit and assumed the lead with rain just three miles out. The gamble failed and he pitted before the restart.[23]

Kyle Larson led the field to the restart on lap 130. He too failed on his gamble, pitted for gas three laps later and gave the lead to Kurt Busch. “Yeah, we could see weather coming there off of (Turn) 4 and just praying that it would get here in time for me to stay out and be in the lead when the rain did hit,” Larson said. “Hey, I applaud my guys for trying. We are pretty deep in points so we have to take risks like that to make the Chase. I’m happy with the call, just wish the rain would have come three laps sooner.”[26] The fifth caution of the race flew with 64 laps to go for rain. The field was brought down pit road and the race was red flagged for the fourth time with 62 laps to go.[27] Eventually, NASCAR called the race due to darkness being near and no sign of the weather letting up and Kurt Busch scored his 27th career win and third at Michigan, similar to the rain-shortened Coke Zero 400 last year when Aric Almirola scored his first career win at Daytona.[28]

“(Crew chief) Tony Gibson led these guys through a back-up car, the pit crew was there giving it its best,” Kurt Busch said. “It’s an unbelievable feeling to know what we went through, paced ourselves and found the lead towards the latter part of the race and then the rain came in.”[30] “Yeah, I mean, you just had to wait on the weather to get moved out, wait on them to dry the track,” Earnhardt Jr. said after finishing second. “You know, it didn't give you a whole lot of opportunities to understand your car and know exactly how to adjust your car and what to work on, so we were still dealing with some issues that we wanted to improve when the final shower came.”[30] “We were able to use the strategy to our benefit and come out of here with a top-10 effort and that feels great for this team,” Trevor Bayne said of his season-best finish of ninth. “We have been working hard to get up better results all season and to get this ninth place finish today is a confidence and momentum builder.”[30]

In his weekly Monday appearance on the Sirius XM NASCAR Radio program The Morning Drive, NASCAR Executive Vice-President and Chief Racing Officer Steve O'Donnell explained to Mike Bagley and Pete Pistone the process and reasoning to why the race was called before its scheduled conclusion.[29]
