The 2016 FireKeepers Casino 400 was a NASCAR Sprint Cup Series stock car race held on June 12, 2016, at Michigan International Speedway in Brooklyn, Michigan. Contested over 200 laps on the D-shaped oval, it was the fifteenth race of the 2016 NASCAR Sprint Cup Series.

Background The race was held at Michigan International Speedway, a moderate-banked D-shaped speedway located in Brooklyn, Michigan. Entering the race, Kevin Harvick leads the points with 490, while Kurt Busch is 25 points back, Brad Keselowski is 48 points back, Carl Edwards is 53 points back, and Kyle Busch is 74 points back.

Harvick, Kurt Busch, Keselowski, Edwards, Kyle Busch, Jimmie Johnson, Martin Truex Jr., Matt Kenseth, and Denny Hamlin have already clinched a Chase position.

Aero package Two weeks prior to the race, NASCAR announced they will test changes to the aero package. In addition to the aero changes used in the 2016 NASCAR Sprint All-Star Race, there will be a reduction in spoiler size from to , a reduction of the splitter and resizing the deck fin.

NASCAR Executive Vice-president and Chief Racing Development Officer Steve O'Donnell said that NASCAR looks "at it as a never-ending journey; if we can improve we’re going to do that. We wanted to go the direction of low downforce, see how that worked, not kind of go all the way in and hope that we are directionally right. And we are seeing that play out. We’ve seen some great racing at the beginning of the year. But we also knew that we had some more levers that we could pull if the direction kind of proved out, so we’ve tried some of those things. We’ve tested it and what we’ve also wanted to do is lower some of the corner speeds to allow for even more passing. That was one of the areas where we’ve seen minimal change, but there are some levers we can pull to really drive that down.”

Entry list The preliminary entry list for the race included forty cars and was released on June 3, 2016, at 12:29 pm ET.

Qualifying Joey Logano scored the pole for the race with a time of 36.080 and a speed of . He said afterwards that starting first "feels good. Finally, we were able to break through. The last two weeks have stunk for me and my team. We have won the first two rounds the last few weeks and qualified second. Now we figured out how to be second in the first round and first in the last two. That is a good move. I couldn’t be more proud of the team and the effort they put into this new package. This is such an unknown showing up here so it is cool to show what all the engineers and simulation department were able to do to put together a good package off the truck. I am very happy to be driving this car.”

Martin Truex Jr. said after qualifying second that the track was slippery and hot.

After qualifying third, Tony Stewart said his team is "gaining on it. We've just got to get a little break here to get going. We were going good last week. The guy that won the race, our teammate [Kurt Busch], we were running the same lap times as him the whole race until we had our problem."

The session was halted in the first round after David Ragan spun out and tagged the wall with his right-rear corner.

Race

First half

Start

Under mostly sunny Michigan skies, Joey Logano led the field to the green at 1:19 p.m. He got loose in turn 1 and Martin Truex Jr. took the lead. In the first 10 laps, a number of drivers were reporting being "incredibly loose" because of the changes made to the aero package. Logano made his back to the lead on lap 11. By lap 25, Truex began reeling him in for the race lead. Green flag stops began around lap 39. Logano pitted from the lead two laps later and handed it to teammate Brad Keselowski. Landon Cassill was tagged for his crew being over the wall too soon and was forced to serve a pass-through penalty. Keselowski ran out of gas on the frontstretch on lap 46. He was saved by Truex spinning out in turn 3 which brought out the first caution of the race. He made it to pit road and the lead cycled back to Logano.

Second quarter The race restarted on lap 51. Kyle Busch's car caught fire in the engine area and blew up on the backstretch. This brought out the second caution of the race on lap 54. He said afterwards that he felt "the motor kind of going south for about 30 laps or so and finally let go. At least there was plenty of warning and I knew it was going to get hot in there and it certainly did once it let go and it was on fire. It’s just been a dismal month, just haven’t been able to hit anything and get good finishes going." He would go on to finish 40th.

The race restarted on lap 61. The third caution of the race flew on lap 62 for a two-car wreck on the backstretch. Exiting turn 2, Chris Buescher got loose and tapped the left-rear corner of Dale Earnhardt Jr. He got loose, came across the nose of A. J. Allmendinger and sent them both into the wall. Earnhardt continued down the backstretch and spun down the track. Earnhardt said afterwards that he "knew I was going to hit the wall. The No. 34 (Buescher) just drove into the left front quarter panel. Oh, man. I don’t know; them restarts and all that. You’ve got a responsibility to try and take care of everybody out there even when you’re three-wide. I’m disappointed in that. But, we had a pretty good car and we were just kind of taking our time, there. And the car was great. So, it’s a shame.” When asked about the wreck from his point of view, Allmendinger said he wasn't “really sure. I think Junior got hit and I was on the outside of him and that was it. It was kind of weird back there. I’m not really sure what kind of car we had. I thought in clean air we weren’t too bad, but I guess a lot of people could say that. Just not a lot of fun racing there.”

The race restarted on lap 69. A number of cars began pitting on lap 93. Logano pitted the next lap and handed the lead to Kyle Larson. He pitted the next lap and handed the lead to Keselowski. He pitted on lap 99 and handed the lead to Jimmie Johnson. The fourth caution of the race flew on lap 102 for Jeffrey Earnhardt slamming the wall in turn 2. Johnson pitted under the caution and the lead cycled back to Logano. Aric Almirola was tagged for having too many crew members over the wall and restarted the race from the tail-end of the field.

Second half

Halfway The race restarted on lap 107. The fifth caution of the race flew on lap 109 after Jeffrey Earnhardt's car caught on fire after slamming the wall a second time on the backstretch.
