Dover International Speedway (formerlyDover Downs International Speedway) is arace track inDover,Delaware,United States. Since opening in 1969, it has held at least twoNASCAR races. In addition to NASCAR, the track also hostedUSAC and theVerizon IndyCar Series. The track features one layout, a 1 mile (1.6 km) concreteoval, with 24° banking in the turns and 9° banking on the straights. The speedway is owned and operated byDover Motorsports.

The track, nicknamed "The Monster Mile", was built in 1969 by Melvin Joseph of Melvin L. Joseph Construction Company, Inc., with an asphalt surface, but was replaced with concrete in 1995. Six years later in 2001, the track's capacity moved to 135,000 seats, making the track have the largest capacity of sports venue in the mid-Atlantic. In 2002, the name changed to Dover International Speedway from Dover Downs International Speedway afterDover Downs Gaming and Entertainment split, making Dover Motorsports. From 2007 to 2009, the speedway worked on an improvement project called "The Monster Makeover", which expanded facilities at the track and beautified the track. After the 2014 season, the track's capacity was reduced to 95,500 seats.

Matt Kenseth entered Dover with a six–point lead overDenny Hamlin.^[12]Carl Edwards andJoey Logano entered tied for third 10–points back.^[13]Jimmie Johnson entered fifth 16–points back.^[14]Ryan Newman entered sixth 25–points.^[14]Kurt Busch entered seventh 26–points back.^[15]Brad Keselowski entered eighth 27–points back.^[16]Martin Truex Jr. entered ninth 28–points back.^[17]Jeff Gordon entered 10th 31–points back.^[18]Jamie McMurray entered 11th 41–points back.^[19]Dale Earnhardt Jr. entered 12th 42–points back.^[20]Kyle Busch andPaul Menard entered tied for 13th 43–points back.^[21]Kevin Harvick entered 15th 65–points back.^[22]Clint Bowyer entered 16th 81–points back.^[23]

In the week leading up to the race, theNational Hurricane Center began tracking the development of a storm several hundred miles south-southwest of Bermuda.^[24] On September 30, the storm was upgraded toHurricane Joaquin.^[25] The forecast model from theNational Weather Service had the storm potentially affecting the race weekend.^[26] However, updated models had the storm avoiding landfall on the Eastern U.S. seaboard and moving out into the North Atlantic.^[27] Nevertheless, heavy rain was expected to affect the Dover area.^[28]

At the request of the drivers, on the Thursday before the race, NASCAR announced that the restart zone would be expanded from 70 feet (21 m) to 140 feet (43 m).^[29] Denny Hamlin took to Twitter to say NASCAR made a great move "to double the restart zone" and that it would give the leader of the race "more of an opportunity to decide when to start the race."^[30] Joey Logano said he was "[g]lad to see @NASCAR expanding the restart zone" and that it was "what a lot of drivers were asking for."^[31]

The following scenarios were in play for this race.

Carl Edwards would clinch a spot in the Contender Round if he finished 32nd or better with no laps led, 33rd if he led a lap or 34th if he led the most laps.^[32]Joey Logano would clinch by finishing at least 31st or better, 32nd with a lap led or 33rd with most laps led.^[32] Jimmie Johnson would clinch if he finished 25th or better, 26th if he leads a lap or 27th if he leads the most laps.^[32] Ryan Newman would clinch if he finished 16th or better, 17th if he led a lap or 18th if he led the most laps.^[32] Kurt Busch would clinches if he finished 15th or better, 16th if he led a lap or 17th if he led the most laps.^[32] Brad Keselowski would clinch if he finished 14th or better, 15th if he led a lap or 16th if he led the most laps.^[32] Martin Truex Jr. would clinch if he finished 13th or better, 14th if he led a lap or 15th if he led the most laps.^[32] Jeff Gordon would clinch if he finished 10th or better, 11th if he led a lap or 12th if he led the most laps.^[32]

Jamie McMurray,Dale Earnhardt Jr.,Kyle Busch,Paul Menard,Kevin Harvick andClint Bowyer controlled their destinies only if they won.^[32] Otherwise, as would turn out to be the case for Earnhardt and Busch, they were dependent on other non-clinched drivers having bad point days.

The entry list for the AAA 400 was released on Friday, September 25 at 2:27 p.m. Eastern time. Forty-four cars were entered for the race. The four driver changes for this race wereJ. J. Yeley returning to the No. 26BK Racing Toyota,Josh Wise returning to the No. 32Go FAS Racing Ford,Alex Kennedy returning to the No. 33Hillman-Circle Sport LLC Chevrolet for the first time sinceWatkins Glen andReed Sorenson returning to the No. 98Premium Motorsports Ford. The threat of rain forcedThe Motorsports Group to withdraw its No. 30 Chevrolet entry from the race.^[33] Because of the withdrawal, all 43 cars remaining entered cars made the race.

Because inclement weather forced NASCAR to cancel qualifying, along with the Friday practice session, the lineup was set by points.^[34] As a result,Matt Kenseth was given the first starting spot.^[35] He said that everybody "would have liked to get on the track today and get some practice. I know there are some things we wanted to work on and try to improve from the spring for this race. I think everybody wanted to get on the track. I think it’s one of the advantages of leading the points – obviously if it rains you get a good starting spot and pit stall. Glad we’re starting in the front, but still would have liked the track time.”^[36]

Kasey Kahne was the fastest in the first practice session with a time of 22.429 and a speed of 160.506 mph (258.309 km/h).^[39]

Kevin Harvick was the fastest in the final practice session with a time of 23.072 and a speed of 156.033 mph (251.111 km/h).^[40] The session only lasted 15 minutes before rain cut it short.^[41]

Under cloudyDelaware skies,Matt Kenseth led the field to the green flag at 2:51 p.m. It only took until lap 3 for the first caution of the race to come out.^[42] This was whenJosh Wise made contact withJeb Burton in turn 1 and sent him spinning.^[43]

The race restarted on lap 7. Just 10 laps later, Kenseth pulled to a one-second lead over his teammateDenny Hamlin. This lead began shrinking over the next six laps to just a quarter of a second overKevin Harvick, who eventually took over that position on lap 25. As Harvick stayed out in front, he pulled to a two-second lead over Kenseth. The second caution of the race flew on lap 41. This was a scheduled competition caution for all the rain that the state of Delaware had throughout the entire weekend. Harvick swapped the lead with Kenseth on pit road and Hamlin exited with the lead. It was short-lived, as he andJimmie Johnson were both tagged for speeding on pit road and restarted from the tail-end of the field. This would give the lead back to Harvick.^[43]

The race restarted on lap 46. Harvick pulled to a five-second lead overKyle Busch after 40 laps. After falling to the back on the restart for the speeding penalty, Hamlin was put down a lap by Harvick on lap 90. Jimmie Johnson made an unscheduled stop on lap 103 for an issue with the drive line.^[44] They couldn't fix it on pit road and he took the car to the garage.^[44] Following the race, he said that it was "tough having a very inexpensive axle seal be the culprit and take your championship hopes away. It's racing. I’ve had mechanicals take me out of championships growing up that led to some success for myself and I’m sure helped me with a championship or two. It’s just part of racing. It just shows how critical everything is on a race team. And how important every component is and you can’t take anything for granted. Heartbreaking for sure, but I don’t know what else we can do about it we just have to go on and try to win races and close out the season strong.”^[45] Debris on the front stretch brought out the third caution of the race on lap 111. The debris came from the No. 83 car ofMatt DiBenedetto. Harvick swapped the lead with Busch on pit road, but exited with the lead.^[43]

The race restarted on lap 118. Harvick once again pulled away from the field and began putting cars several of laps down. After 30 laps, he had lapped over half the field at least once. After 60 laps, he lapped everyone up toBrad Keselowski, who sat in 14th place. The fourth caution flew on lap 193 when Jeb Burton suffered a right-front tire blowout and slammed the wall in turn 2.^[46] He would go on to finish last.^[46] Harvick and Kyle Busch swapped the lead on pit road, but exited with the lead.^[47]

The race restarted on lap 206. Debris on the front stretch brought out the fifth caution on lap 232. Harvick and Busch swapped the lead on pit road. This time, however, Busch took just right-side tires and exited with the lead. Hamlin was tagged for speeding on pit road and restarted from the tail-end of the field.^[43]

The race restarted on lap 237. Harvick didn't waste any time passing the third and second–place cars. He drove under Busch in turn 2 to retake the lead on lap 249. The sixth caution flew on lap 312 whenA. J. Allmendinger got loose and spun out in turn 4 while trying to get on pit road.^[42] Harvick and Busch again swapped the lead on pit road, but Harvick exited with it. With the stop being outside the 85-lap fuel window, most of the cars on the lead lap began shutting off their engines to conserve fuel.^[43]

The race restarted with 84 laps to go. The seventh caution of the race flew with 47 laps to go for a single-car wreck in turn 1.Brett Moffitt suffered a right-front tire blowout and slammed the wall.^[42] Matt Kenseth opted not to pit under the caution and assumed the lead.^[43]

The race restarted with 42 laps to go. Kenseth was no match for Kevin Harvick on old tires and lost the lead to Kevin. The eighth caution of the race flew with 29 laps to go for fluid on the track.^[42] The fluid came from the No. 40 car ofLandon Cassill after his engine blew up.^[43]

The race restarted with 24 laps to go. Kevin Harvick drove on to score his 31st career victory. While Jamie Mcmurray, Jimmie Johnson, Paul Menard and Clint Bowyer were the 4 drivers eliminated from the chase. J^[48]

Harvick said that he was "just so proud of everybody fromStewart-Haas Racing to do everything that we’ve done the last three weeks, really. Obviously we weren’t in a great position coming in to today. That’s what these guys are made of and that’s what teamwork is all about."^[49]

Following his runner-up finish, Kyle Busch said that the day was "really good...for us. I can't say enough about this entire Interstate Batteries team. They did a great job today. Adam Stevens gave me a great piece and when you look at the amount of practice time we had, it was pretty hard to figure out what you had. We had a second–place car and we finished second with it; nothing to hang our heads about."^[50]

Dale Earnhardt Jr. finished third and advanced to the Contender Round on a tiebreaker.^[51] After the race, he said that the closing laps weren't "nerve-wracking at all. You're either going to make it or you ain't. I'm going to try put together the best lap I can put together, and drive the car as hard as you can without over-driving it. You can't really worry about the big picture because you have to concentrate on running the lap. This place is so technical that you just have to concentrate on every corner and the mistake you made on the last one and how you make a better corner the next time through there. That's all you really worry about."^[52]

Jamie McMurray failed to make the Contender Round on a tiebreaker with a fourth–place finish.^[53] After the race, he said that he was "driving so hard those last few laps, and it’s just hard to make up any ground. And it seemed like our car was maybe better on stickers,” McMurray explained. “We haven’t run this well, honestly. We talked earlier today about that. So, I’m thrilled with our performance today. It’s frustrating that we weren’t able to make it to the next round, but it was a good day for the Nature Made car. We just needed one more point.”^[54]

After driving under the radar to a fifth–place finish,Aric Almirola said that his team did "a really good job. We just struggled with getting the car in the race track most of the day and right there at the end four tires paid off for us. That was some really good adjustments by Trent and the guys and the pit crew did a good job getting me off pit road and just a really solid day for us.”^[55]

Martin Truex Jr. drove from the rear of the field to an 11th–place finish.^[56] He said after the race that he didn't have "a great day...It wasn’t a great weekend. We have been struggling trying to get the thing turning. All in all we had good speed when we would get track position. We would lose track position and being in long lines on the restarts when we couldn’t really go anywhere. It was really difficult to pass today. We had good speed out front, top five speed and then just never really could get back there once we got back in traffic.”^[56]

A 12th–place finish was enough forJeff Gordon to advance into the Contender Round.^[57] After the race, he said that making it involved "a lot of hard work. I'm proud of these guys. We fought hard and that's what we've been doing all year long. It hasn't been pretty. We've had a lot to overcome and we never give. That was pretty much what he had today, we survived and made it through."^[58]

After a 14th–place finish wasn't enough to getClint Bowyer into the Contender Round, he said after the race that his "5-Hour Energy Toyota was good today, I’d say a top-five car. We just had some bad luck with that loose wheel early on. We got two laps down, but were able to make those up. No one had anything for that 4 car (Harvick), though.”^[59]

Following his 25th–place finish that kept him from advancing to the Contender Round,Paul Menard said that it "was not a good day for us at Dover. We fought handling all day and found out there was a mechanical issue there near the end. We gave it our all and I'm proud that we got here. Hate that we don't get to compete further into the Chase, but we will work for a win and to advance our spot from where we are.”^[60]
