The 2015 Bojangles' Southern 500, the 66th running of the event, was a NASCAR Sprint Cup Series race held on September 6, 2015, at Darlington Raceway in Darlington, South Carolina. Contested over 367 laps on the 1.366 mile (2.198 km) egg-shaped speedway, it was the 25th race of the 2015 NASCAR Sprint Cup Series season. Carl Edwards won the race, the 25th of his career. Brad Keselowski finished second. Denny Hamlin, Joey Logano and Kevin Harvick rounded out the top five.

Keselowski won the pole for the race. He led a race high of 196 laps on his way to a runner–up finish. The race had 24 lead changes among 11 different drivers, as well as 18 caution flag periods for 89 laps.

This was the 25th career victory for Carl Edwards, second of the season, first at Darlington Raceway and fifth at the track for Joe Gibbs Racing. The win moved Edwards up to 12th in the drivers points standings 235 behind Kevin Harvick. Despite being the winning manufacturer, Toyota left Darlington trailing Chevrolet by 63–points in the manufacturer standings.

The Bojangles' Southern 500 was carried by NBC Sports on the broadcast NBC network for the American television audience. The radio broadcast for the race was carried by the Motor Racing Network and Sirius XM NASCAR Radio.

Report

Return to Labor Day

From 1950 to 2003, the Bojangles' Southern 500 was run on Labor Day weekend in late-August or early-September. For the 2004 season, the race (then known as the Mountain Dew Southern 500) was moved to the penultimate race of the season while a second race at Auto Club Speedway was added into the Labor Day spot. The Southern 500 was discontinued as a result of the Ferko lawsuit. Fontana kept the Labor Day weekend date from 2004 to 2009, when it moved to October. Atlanta Motor Speedway moved to the Labor Day spot and remained there from 2009 to 2014. During that time, the spring race (Rebel) would become a 500-mile race and moved up to Mother's Day weekend in May 2005 (when the lineal Rebel 300 was first run in 1957) and remained there for eight years. It then moved to mid-April for 2014. In August of that year, NASCAR announced Darlington's date, which still is the race that traces its lineage to the 1957 Rebel 300, would be held on Labor Day. It was the first time Darlington hosted on the date since 2003.

Members of the NASCAR media gave their thoughts on the return to Labor Day weekend. Pete Pistone of the Motor Racing Network said that Labor Day weekend in Auto Club "never felt right," Labor Day weekend in Atlanta "was better but still not quite there," that Darlington Raceway "fits like a glove" and is "back to where you belong, Bojangles' Southern 500. Don't ever go away again."

In ESPN.com's weekly Turn 4 series, NASCAR analysts and writers Ricky Craven, Ryan McGhee, John Oreovicz, and Bob Pockrass answered the week's question "Why did it take so long for NASCAR to move the Labor Day race back to Darlington[.]" Craven said that he "wasn't sure" but "[f]ew things are more powerful in sports than the power of tradition. This race is synonymous with Labor Day weekend. Moving it to a spring race felt like inviting Santa Claus to Halloween." McGhee said that going back meant "admitting a mistake. NASCAR doesn't like that. Otherwise, we would have gone back to the 2014 aero package six months ago." Oreovicz said it most likely was because NASCAR "doesn't do anything until [they decide] it's a good idea, no matter how popular the idea might be to the masses. But this is another sign that NASCAR is actually listening to its constituents a bit more these days." Pockrass said that "[s]tubbornness and refusal to admit failure" was his guess and that it was "one of NASCAR's most head-scratching moves in trying to build the sport. NASCAR should have never messed with this tradition in the first place. NASCAR didn't belong in California on Labor Day weekend. It didn't belong in Atlanta. It belongs in Darlington, South Carolina. And it's back. Finally."

Jordan Bianchi of SB Nation said that there are traditions that are "just too important. They are the institutions that shouldn't be tampered with under almost any circumstance, worthy of being shared from one generation to the next." He also added that by returning "Darlington to Labor Day weekend, NASCAR has righted a wrong; even if it was a tradition that should have never been abandoned in the first place."

Mike Hembree of USA Today called the initial decision of moving the race from Labor Day weekend "[s]ports blasphemy of the highest order" and its return to Labor Day weekend as being "back where, as people in this farming section of South Carolina will tell you, God meant it to be."

Change to the track Since its most recent Sprint Cup Series race in April 2014, Darlington Raceway added of additional SAFER barrier to both the front and backstretch walls. This made Darlington the second track on the Sprint Cup schedule, after Bristol, to line the entire circumference of the outside retaining wall with the energy-absorbing barrier.

For this race, NASCAR redesigned the restart zone so that it would be more visible and eliminate driver complaints about "jumped restarts."

Aero package For this race, teams used the low-downforce aero package that was used at Kentucky Speedway. This package included a spoiler (reduced from ), a radiator pan (reduced from ) and a quarter inch (.64 cm) leading edge splitter.

New tire compound For this weekend's race, Goodyear brought a softer tire compound to go with the low-downforce package. These changes included different construction and mold shapes for the left-side tires and the right-side tires would provide more grip.

Throwback paint schemes In celebration of the event, 32 of the 46 teams entered for this weekend's race unveiled throwback and special paint schemes as part of the return of the Bojangles' Southern 500 to Labor Day weekend. Chip Wile, track president of Darlington Raceway and brainchild of the throwback idea, had initially thought maybe eight or 10 teams could be persuaded to take part in this and get more teams to do it next season. He told Jeff Gluck of USA Today that he thought "this is bigger than what people imagined what it would be in [y]ear [one]" and that he thought "the sport needed this. NASCAR has such a rich history, and we need to celebrate that."
