2015 Sprint Unlimited

Matt Kenseth took the victory ahead of Martin Truex Jr. Carl Edwards, Casey Mears, and Kyle Larson rounded out the top five.

[9] The standard track at Daytona International Speedway is a four-turn superspeedway that is 2.5 miles (4.0 km) long.

[12] Tony Stewart was called to the NASCAR hauler for ignoring the black flag which was shown to him, as he did not weigh in before the session.

[13] Per NASCAR regulations, all drivers had to weigh in before the start of the season to calculate the minimum car weights.

[13] Jeff Gordon was the fastest in the final practice session with a time of 45.740 and a speed of 196.764 mph (316.661 km/h).

[15] Coming to the start-finish line, Kyle Larson made contact with Brad Keselowski, while trying to merge into the top lane of cars.

[17] Aric Almirola, Clint Bowyer, Kurt Busch, Kyle Busch, defending race winner Denny Hamlin, Kevin Harvick, Jimmie Johnson, Kasey Kahne, McMurray, Paul Menard, Ricky Stenhouse Jr. and Tony Stewart were all taken out or sustained damage in the crash.

[17] McMurray stated that Biffle has "got me loose a couple of times before" but that it was customary for Daytona racing, adding that "you're fighting for every position every lap and he just got into me a little too hard off four and I couldn't hang on to it".

The race restarted with nine laps to go, before the fourth caution of the race flew with seven laps to go after Stewart got loose exiting turn 2 and collected Biffle, who hit the inside retaining wall in a manner similar to Danica Patrick in the 2012 Gatorade Duels.

The red flag was displayed a second time; after a five-minute delay, Kenseth held off the field until the end of the race, to win ahead of Truex Jr. and Carl Edwards.

Harvick stated that "you can't just drive somebody straight in the corner into the fence" and that Logano "kind of did the same thing to me at Talladega".
