The 2015 Ford EcoBoost 400 was a NASCAR Sprint Cup Series race held on November 22, 2015, at Homestead-Miami Speedway in Homestead, Florida.

Contested over 267 laps on the 1.5 mile (2.4 km) oval, it was the 36th and final race of the 2015 NASCAR Sprint Cup Series season.

Jeff Gordon finished sixth in his 797th and final scheduled career start and Martin Truex Jr. rounded out the Chase drivers in 14th.

This was the 34th victory for Busch, fifth of the season, first at Homestead-Miami Speedway and sixth at the track for Joe Gibbs Racing.

Jeff Gordon was the first of the four drivers to clinch a spot in the championship four, winning the first race of the Eliminator Round at Martinsville.

[15] Gordon struggled during the early portion of the season, being involved in crashes in the first two races and was as low as 35th in points.

[14] At Martinsville, he clinched a spot in the final four by taking advantage of Team Penske drivers Joey Logano and Brad Keselowski's accidents to claim his 93rd career victory.

[17] Kevin Harvick, the defending Cup champion, finished second behind Dale Earnhardt Jr. at Phoenix to clinch his place in the championship race.

[19] However, Harvick struggled in the first two races of the Chase, crashing at Chicago and running out of fuel while leading at Loudon.

[20] At Talladega, Harvick – once again faced with the possibility of being eliminated from the Chase and a struggling car – was involved in a controversial restart crash on the green–white–checker finish when he collided with Trevor Bayne and caused a crash with intentions of defending his Chase spot.

[21] Kyle Busch finished fourth at Phoenix to clinch his spot in the championship race.

[24] He then proceeded to win three consecutive races, making him the first driver since the 2007 season to accomplish the feat.

Truex, considered as the underdog of the championship four,[25] had a strong regular season under new crew chief Cole Pearn.

[27] The following race at Pocono, Truex was able to claim his first victory of the season, third of his career and first since the 2013 Toyota/Save Mart 350 at Sonoma Raceway.

"[28] On August 22, 2015, Michael Waltrip Racing announced that the team would terminate operations at the end of the 2015 season.

[31] David Ragan – who drove for Front Row Motorsports, Joe Gibbs Racing and MWR in the 2015 season – was without a ride going into the offseason.

All but Ryan Blaney and Michael McDowell were entered in the previous week's race at Phoenix.

[34] The session was red-flagged 39 minutes in when Ryan Preece went up in smoke and started leaking power steering fluid.

We have a very strong race car in this Axalta Chevrolet, obviously, because to be able to do that the next couple of runs; I’m pretty proud of those laps.

I’m really happy and proud of that.”[37] Kyle Larson was the fastest in the second practice session with a time of 30.680 and a speed of 176.010 mph (283.261 km/h).

[40] The track was dried and under mostly sunny Florida skies, Denny Hamlin led the field to the green flag at 5:15 p.m..

Jeff Gordon drove underneath Busch and Carl Edwards to take the lead the next lap.

After being released from the infield care center, Bowyer said that exiting "two, my car got loose, and I couldn’t catch it.

During his stop, a fire started in his pit stall that forced his gas man to cease fueling the car before it was completed.

It was for a piece of metal lying under the flag stand while NBC mistakenly showed what appeared to be a plastic bottle on the apron as the debris that brought out the caution.

I thought there at the end that the restart, we might do a little better than that, but obviously either the splitter was on the ground or the car was just tighter than it probably needed to be, and just I couldn't hustle it and got it tight and got it up the racetrack and got behind.”[53] Following a third-place finish, Keselowski said that he "led a lot of laps.

I was really proud of my team tonight, really happy with what they were able to give me, and we were able to take a run at it, we just didn't quite have enough at the end on that final restart to hold those guys off.

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.

Alex Hayden, Winston Kelley and Steve Post handled pit road on the radio side.
