The 2015 Coke Zero 400 powered by Coca-Cola was a NASCAR Sprint Cup Series race that was held between July 5 and 6, 2015 at Daytona International Speedway in Daytona Beach, Florida. Contested over 161 laps – extended from the scheduled 160 laps – on the superspeedway, it was the 17th race of the 2015 NASCAR Sprint Cup Series season. Dale Earnhardt Jr. won the race, his second win of the season. His teammate Jimmie Johnson finished second while Denny Hamlin, Kevin Harvick, and Kurt Busch rounded out the top five.

With qualifying rained out, the field was set by first practice speeds and Earnhardt Jr. was given the first starting spot as a result. Further rain delays pushed the race's green flag back to 11:42 p.m., with the race concluding at 2:40 a.m. ET the following morning. Earnhardt Jr. led a race high of 96 laps on his way to winning the race. The race had 22 lead changes among twelve different drivers, as well as nine caution flag periods for 43 laps. The race was marred by a violent crash at the finish, most notably featuring Austin Dillon's car flipping into the outside catch fence.

It was Earnhardt Jr.'s 25th career victory, tenth career restrictor plate race win (in points competition), fourth at Daytona, and 14th at the track for Hendrick Motorsports. The win moved him up to second in the points standings. Chevrolet left Daytona with an 83-point lead over Ford in the manufacturer standings.

The event was also the first NASCAR Sprint Cup Series event to air on NBC since 2006 as part of a ten-year deal signed in 2013 in which NBCUniversal and its networks would broadcast the final half of the NASCAR Sprint Cup and Xfinity Series season.

Report

Background Kevin Harvick entered Daytona with a 53-point lead over Martin Truex Jr., Joey Logano entered 57 back, Jimmie Johnson entered 70 back, and Dale Earnhardt Jr. entered 71 back.

Changes During the Xfinity Series' Alert Today Florida 300 earlier in the year, a crash occurred in which Kyle Busch slammed into a concrete wall just past the exit to pit road, breaking his leg and sidelining him for the first eleven races of the Sprint Cup season. In response to the accident, the entire outer wall of the race track was fitted with SAFER barriers. The grass near the entrance of turn 1 and towards the exit of the tri-oval, where Busch's accident occurred, were paved over.

At the request of the race's broadcaster, NBC, the 2015 Coke Zero 400 was moved from its traditional Saturday night scheduling to Sunday night. Track president Joie Chitwood III explained that NBC wanted to treat the race as a special event to launch its revived coverage, similarly to NBC's Sunday Night Football. The move also removed a potential conflict with NBC's annual Macy's 4th of July Fireworks Spectacular special.

Entry list The entry list for the Coke Zero 400 was released on Monday, June 29 at 11:41 a.m. EDT. Forty-five cars were entered for the race. All but the No. 21 Wood Brothers Racing Ford driven by Ryan Blaney were entered for the previous race at Sonoma Raceway. Driver changes for this race include Bobby Labonte in the No. 32 Go FAS Racing Ford normally driven by Mike Bliss, Brian Scott in the No. 33 Hillman-Circle Sport LLC Chevrolet normally driven by Alex Kennedy, and Brett Moffitt returning to the No. 34 Front Row Motorsports Ford.

Practice

First practice Dale Earnhardt Jr. was the fastest in the first practice session with a time of 44.492 and a speed of . Ten minutes into the session, Brad Keselowski made contact with Kyle Busch and sent him spinning in the middle of the pack. Michael Annett, Trevor Bayne, Greg Biffle, Carl Edwards, Denny Hamlin, Sam Hornish Jr., Jamie McMurray, Ryan Newman and Martin Truex Jr. were all collected in the wreck. “The 2 car got on my back rear and just spun us around,” Busch said. “There’s room to lift and sometimes you don’t.” “A couple of guys got in front of me right there,” Truex said. “They started checking up in front of me and the 18 went sideways, a lot of damage. We’re going to a backup car.”

Qualifying

Two rounds of single-car qualifying were scheduled to take place on Saturday at 4:35 p.m. Eastern Daylight Time, but were cancelled due to rain. The lineup was set by first practice results. So Dale Earnhardt Jr. was declared as the polesitter per the NASCAR rulebook. “I asked Greg (Ives, crew chief) before we went out to practice what we were trying to accomplish in that first practice and that was the first thing he mentioned was to go out that first run and try to put a lap down because the weather wasn’t looking real good for today," Earnhardt said. "That was his decision. It ended up working out for us.” "This track has been very special to me, we know how important is to the sport," said Jeff Gordon, who'll start 23rd in his 46th and final career race at Daytona. "I'm kind of bummed out that it was rained out." Despite posting the 22nd fastest lap in first practice, Ryan Blaney failed to make the race. When qualifying is rained out, NASCAR's rules state that the number of attempts a race team has made determines the starting lineup before practice times. As a result, the No. 21 Wood Brothers Racing Ford failed to qualify for the first time in seven years. “I really hate this for Motorcraft/Quick Lane and all of our guests,” team co-owner Eddie Wood said in a release. “We’ve been lucky. This is the first time this has happened since we started part-time in 2009. We’ve dodged a lot of bullets, including last time in Michigan. This one got us, but if it has to happen, I’d rather it be for something we can’t control instead of for a lack of performance on our part.”
