In addition to NASCAR, the track also hosted USAC and the Verizon IndyCar Series.

Kyle Larson was the fastest in the first practice session with a time of 21.742 and a speed of 165.578 mph (266.472 km/h).

[14] Under overcast Delaware skies, Brad Keselowski led the field to the green flag at 2:17 p.m.

Debris coming from Kevin Harvick's car brought out the first caution of the race on lap 34.

The issue was a flat right-rear tire related to a broken track bar mount.

[15] Trevor Bayne was sent to the tail end of the field for speeding on pit road.

Kyle Larson fell down a lap after making a stop to deal with electrical issues.

The second caution of the race flew on lap 104 for Ryan Blaney hitting the wall exiting turn 2.

Jamie McMurray was running 10th when he reported engine issues and started falling back on lap 167.

The third caution of the race flew on lap 182 for Larson suffering a right-front tire blowout and slamming the wall in turn 1.

I cut the right-front tire down and got in the wall and still had good speed in the race car after that but it just didn’t work out.

I know we have the speed to have made it past a couple of rounds but it’s my typical luck I guess, where it just doesn’t work out.”[19] The race restarted on lap 190.

McMurray brought out the fourth caution of the race after suffering an engine failure on the frontstretch.

It felt like it had power and then I don't know about 40 laps before it finally blew up, it just started vibrating real bad.

42 had their problem early in the race and then at that point I'm like, ‘Well it's kind of Austin (Dillon) and I that are going to battle this out.’ Our cars are pretty close so this is going to be a pretty good battle down to the end.”[19] He also added that keeping the car out as long as he did with engine issues was "wishful thinking at that point.

I got slowed up and had to check up and get behind two cars and unfortunately, I think it just threw the rhythm off of the pit stop.

Today I’m just thankful to have a great team, to have been able to lead lap 400 and get back to victory lane at a track that’s so special to me.”[27] After advancing into the Round of 12 with an eighth-place finish, Austin Dillon said that his team "just stayed focused, and once again, God just blessed us because I'm still awestruck.

Now let’s go get a top-five or something better at Martinsville.’’[29] "We were much better than we were yesterday [in practice]," Tony Stewart said after being knocked out of his final Chase appearance with a 13th-place finish.

Rick Allen, Jeff Burton, and Steve Letarte had the call in the booth for the race.

Dave Burns, Mike Massaro, Marty Snider and Kelli Stavast handled pit road on the television side.
