2015 Coca-Cola 600

Charlotte Motor Speedway, the track where the race was held.

Charlotte Motor Speedway is a motorsports complex located in Concord, North Carolina, United States 13 miles from Charlotte, North Carolina. The complex features a 1.5 miles (2.4 km) quad oval track that hosts NASCAR racing including the prestigious Coca-Cola 600 on Memorial Day weekend and the Sprint All-Star Race, as well as the Bank of America 500. The speedway was built in 1959 by Bruton Smith and is considered the home track for NASCAR with many race teams located in the Charlotte area. The track is owned and operated by Speedway Motorsports Inc. (SMI) with Marcus G. Smith (son of Bruton Smith) as track president.

The 2,000 acres (810 ha) complex also features a state-of-the-art quarter mile (0.40 km) drag racing strip, ZMAX Dragway. It is the only all-concrete, four-lane drag strip in the United States and hosts NHRA events. Alongside the drag strip is a state-of-the-art clay oval that hosts dirt racing including the World of Outlaws finals among other popular racing events.

Kevin Harvick entered Charlotte with a 46-point lead over Martin Truex Jr. following his runner-up finish. Jimmie Johnson entered 48 back following winning at Kansas Speedway. Joey Logano entered 62 back. Dale Earnhardt Jr. entered 77 back following a third-place finish at Kansas.

For the weekend's race, the names on the windshield of the cars — in lieu of the drivers last names — had those of United States Armed Forces members who've died in the line of duty.[13] “The NASCAR community rallying to honor the U.S. Armed Forces, past and present, has long been part of our sport’s heritage,” said Brent Dewar, NASCAR chief operating officer. “As part of NASCAR: An American Salute, 600 Miles of Remembrance represents a special moment in time as we pay tribute to service members who have sacrificed dearly for our freedom.”[13] The Toyota pace car for the race will follow suit as well.[13]

The Coca-Cola 600 was scheduled to start at 6:20 p.m. but started one minute late with Matt Kenseth leading the field to the green flag. Kenseth wouldn't lead the first lap however, as teammate Carl Edwards took the lead. Kenseth found his way to the head of the field on lap 4. The first caution flew on lap 26. This was a scheduled competition caution that came after Charlotte Motor Speedway general manager Marcus Smith had turns 1 and 2 washed down overnight. Brad Keselowski was tagged for removing equipment from his pit box and restarted from the tail-end of the field. Aric Almirola was tagged for his crew being over the wall too soon and also restarted from the tail-end of the field.[18]

The race restarted on lap 31 and Joey Logano shot out ahead of Kenseth to take the lead on lap 32. Denny Hamlin powered to the outside of Logano in turn 2 to take the lead on lap 44. Kevin Harvick took the lead on lap 65. As a round of green flag pit stops began, he surrendered the lead on lap 79 to make his pit stop and gave it to teammate Kurt Busch, who also was on pit road. This gave the lead to Keselowski, who pitted on lap 81 and gave the lead back to Harvick. The second caution flew on lap 90 when Jimmie Johnson got loose in turn 3 and spun out off the asphalt banking in turn 4. He saved the car and brought it to pit road. Keselowski chose not to pit and assumed the lead.[18]

The race restarted on lap 95. Keselowski was no match for his teammate on fresher tires as Logano took the lead on lap 96. Kurt Busch, who took four tires during the previous caution, took the lead with ease on lap 98. The third caution flew on lap 136 when Justin Allgaier slammed the wall in turn 3.[19]

The race restarted on lap 142, with Kurt Busch still out in front. The race settled into a green flag run. A second series of green flag pit stops began on lap 185, 15 laps to halfway. Busch surrendered the lead to pit on lap 190 and handed the lead to Johnson. He pitted on lap 191 and handed the lead to Edwards. He pitted the next lap and the lead cycled to Martin Truex Jr.[20] Kasey Kahne was tagged for speeding on pit road and was forced to serve a drive-through penalty.[18]

The fourth caution flew on lap 229 when Trevor Bayne collected the wall in turn 3, leaving debris on the racetrack. Ryan Newman was tagged for speeding on pit road and restarted from the tail-end of the field.[18]

The race restarted on lap 236. Kurt Busch took back the lead on lap 238. Truex took back the lead on lap 263. The fifth caution flew on lap 273 when Johnson hit the wall near the entrance to pit road.[21] “We had a really loose racecar," Johnson explained. "We came in with an aggressive mindset to bring an aggressive setup in the car, drive aggressively and take chances. We don’t have anything to lose. Unfortunately, we didn’t get long enough into the race for the aggressive setup to come into play. Another 30/40 laps, we would have had the car right where we wanted it. I just didn’t make it there."[22] "I could see it, I could see that opening and I could see the No. 2 (Brad Keselowski) pit," Johnson said. "I was frightened that I was going to get through that hole. It wouldn’t have been pretty for me, but to have teams and stuff there ... that was something I was staring at sliding for a long way. I was very thankful the SAFER barrier was there. I wish we could find a way to extend a wall out and redirect the car away from that opening, or close that opening up."[22]

The race restarted on lap 279. The sixth caution of the race flew on lap 282 when Ryan Blaney hit the wall.[18]

Carl Edwards, seen here at the 2015 Daytona 500, scored his first win of the season.

The race restarted on lap 292. The seventh caution of the race flew on lap 327 when Michael Annett, exiting turn 2, got loose and spun out on the backstretch.[18]

The race restarted on lap 333. Hamlin took the lead from Truex, Jr. with 67 laps to go. The eighth caution of the race flew with 64 laps to go when Ricky Stenhouse Jr. hit the wall in turn 4, leaving debris on the racetrack.[18]

The race restarted with 59 laps to go. Hamlin made an unscheduled stop with 38 laps to go for a loose wheel. Martin Truex Jr. reassumed the lead. He pitted with 22 laps to go and handed the lead to Harvick. He pitted the next lap and gave the lead to Edwards who drove his way to score the win.[23]

"JGR is back and so is Toyota," said Edwards, who pitted on Lap 338 for fuel and was able to stretch it all the way to the finish as others ran out in the closing laps. "Darian Grubb is so good as a crew chief and when it comes down to fuel mileage, there isn’t anyone else I’d want calling the shots like he did tonight. This is such a huge win."[24] "I was hoping the guys in front of me would run too hard and run out of gas," said Earnhardt. "We had to try to go for a win. We didn’t have a car fast enough to beat the '41' (Kurt Busch) or the '78' (Truex). We had to do something different. I like to gamble."[24] Martin Truex Jr. finished fifth after leading a race high 131 laps.[25] "I didn't even think fuel mileage strategy was an option," said Truex, who also led the most laps in the previous race at Kansas Speedway. "I felt I only needed to pass the No. 11 (Hamlin). We had a very fast car all night. It really hurts knowing that you had the fastest car and didn't win. I don’t know what to do about fuel mileage races. I’ve never ever in my entire career come out on the right end of them."[26] "We didn't make many adjustments throughout the race, the car was fast from the get-go," noted Truex. "Whatever we needed to do, Cole (Pearn, crew chief) and his engineering staff made the right calls. This is a talented team that works extremely hard and I want nothing more than to drive their car to victory lane."[26]

In his first Cup Series points race since his injury, Kyle Busch finished eleventh. He was able to run the whole race, but in the event he couldn't finish, Joe Gibbs racing had Erik Jones ready to complete the race.

On the Wednesday following the race, NASCAR handed out penalties to three Sprint Cup teams.[27]
