The 2015 Windows 10 400 was a NASCAR Sprint Cup Series race held on August 2, 2015, at Pocono Raceway in Long Pond, Pennsylvania.

Contested over 160 laps on the 2.5 mile (4 km) triangular superspeedway, it was the 21st race of the 2015 NASCAR Sprint Cup Series season.

This was the 33rd career victory for Matt Kenseth, second of the season, first at Pocono Raceway and tenth at the track for Joe Gibbs Racing.

“(Crew chief) Adam Stevens and these guys, they did it again.”[15] “A lot of that lies on me for putting the lap together something I hadn’t done over the last couple of months,” Kevin Harvick said after qualifying second.

I got a little bit tight in the center of that corner, but all-in-all it was a good lap and I’m glad we ran our fastest speed in the last round.

“ (Crew chief) Chad Johnston came over in between the practice session and qualifying and showed me some stuff where I was losing some time.

It is similar to what we had at the Brickyard and we were really strong there but just needed a little more to win so I am optimistic about it for sure.”[15] “We really struggled for whatever reason in Turn 1 today,” said Martin Truex Jr. after qualifying 13th “Just can’t seem to get the balance right.

We did it last week.”[15] Carl Edwards was the fastest in the second practice session with a time of 51.191 and a speed of 175.812 mph (282.942 km/h).

[17] Jeb Burton was forced to go to his backup car after wrecking into the inside pit road wall.

The first caution of the race flew on the fifth lap when Kasey Kahne got loose on the frontstretch coming out of turn 3, slid down the track and slammed into the inside wall lining pit road.

I hadn’t done anything like that before so it was kind of crazy the way it all happened.”[18] Kahne was uninjured and he was released from the infield care center a few minutes later, but his car was damaged beyond repair and he finished dead last.

This was a scheduled competition caution after a section of the track was washed down following the previous day's ARCA race.

[21] “"Coming off of Turn 2, I knew I had some issues and didn't realize they were going to be that big, but all in all, just really proud of my team," Harvick said.

The fourth caution of the race flew on lap 28 when Sam Hornish Jr. cut down a left-front tire in turn 1 and got rear-ended by Ricky Stenhouse Jr., who then slammed the wall.

I guess the 9 missed a shift or something and I wasn't aware of it until the 35 (Cole Whitt) or one of the other cars pulled out real quick, and there was the 9 sitting there.

"I missed a shift on a restart, which wasn't any good, and then we had a tire come apart and then we got hit and then that deal right there (with Busch).

I love coming to Pocono and I have had some good runs here and led laps and felt like we could win races, but it just hasn't been for us this year.

"[23] The race restarted on lap 34 with defending Pocono winner Martin Truex Jr. out in front.

Dale Earnhardt Jr. was tagged for speeding on pit road and was forced to serve a drive-through penalty.

Jeb Burton was tagged for speeding on pit road and restarted the race from the tail-end of the field.

The seventh caution of the race flew the same lap when Dale Earnhardt Jr. made contact with Cole Whitt in turn 1 and went spinning.

The eighth caution of the race flew on lap 91 when Alex Kennedy backed into the wall in turn 1.

The field settled into a green flag run until lap 123 when Joey Logano surrendered the lead to pit.

Brett Moffitt was tagged for speeding on pit road and was forced to serve a drive-through penalty.

[20] Logano maintained a one-second lead over Kyle Busch with ten laps to go with a chance of being short on fuel.

I never thought I’d ever win at Pocono and I never thought I’d win a fuel mileage race, so we did both today.”[27] “I guess our numbers, from what (crew chief) Todd (Gordon) said, was good enough to make it by a half a lap,” said Joey Logano after running out of gas and finishing 20th.

[28] "The fuel came into play at the end and we were able to take care of it to bring home second, which is a very respectable day," Keselowski said.

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.

Woody Cain, Glenn Jarrett and Steve Post worked pit road on the radio side.
