2017 Coca-Cola Firecracker 250

The 2017 Coca-Cola Firecracker 250 was the 15th stock car race of the 2017 NASCAR Xfinity Series season and the 16th iteration of the event. The race was held on Saturday, June 30, 2017, Daytona Beach, Florida, at Daytona International Speedway, a 2.5 miles (4.08 km) permanent triangular-shaped superspeedway. Due to inclement weather, the remainder of the race was held on July 1. The race was extended from 100 laps to 104 laps, due to a NASCAR overtime finish. At race's end, William Byron, driving for JR Motorsports, scored his second win in a row after leading the race when the caution came out with two to go. It was Byron's second career win in the xfinity series. He would also become the youngest winner in Daytona history, being only 19-years old. To fill out the podium, Elliott Sadler of JR Motorsports and Dakoda Armstrong of JGL Racing would finish second and third, respectively.
