2013 Sprint Unlimited

Daytona International Speedway, the race track where the race was held.

The track, Daytona International Speedway, is one of six superspeedways to hold NASCAR races, the others being Michigan International Speedway, Auto Club Speedway, Indianapolis Motor Speedway, Pocono Raceway and Talladega Superspeedway.[3] The standard track at Daytona International Speedway is a four-turn superspeedway that is 2.5 miles (4.0 km) long.[4] The track's turns are banked at 31 degrees, while the front stretch, the location of the finish line, is banked at 18 degrees.[4]

A total of twenty-two drivers were eligible to compete in the race, including 2012 pole position winners and previous winners of the race who had qualified for at least one race during the 2012 season,[5] but only nineteen drivers participated in the race.[6] Notable drivers not invited to the race were Brad Keselowski and Clint Bowyer, the 2012 champion and champion runner up, who didn't collect any pole positions in 2012. In yellow are previous Daytona Shootout winners without pole wins in the 2012 season.

Unlike other races, the race format was chosen by a fan poll, and was 75 laps long, with three segments of 30, 25, and 20 laps.[7]
