2018 Coca-Cola Firecracker 250

The 2018 Coca-Cola Firecracker 250 was the 16th stock car race of the 2018 NASCAR Xfinity Series season and the 17th iteration of the event. The race was held on Friday, July 6, 2018, in Daytona Beach, Florida at Daytona International Speedway, a 2.5 miles (4.0 km) permanent triangular-shaped superspeedway. The race was extended from its scheduled 100 laps to 105 due to a NASCAR overtime finish. At race's end, a close, but controversial finish would see Chip Ganassi Racing driver Kyle Larson win his 11th career NASCAR Xfinity Series win and his third of his part-time season. To fill out the podium, Elliott Sadler of JR Motorsports and Christopher Bell of Joe Gibbs Racing would finish second and third, respectively.

In a controversial ruling, GMS Racing driver Justin Haley, who had initially won the race was instead disqualified from his win due to him passing Larson below the yellow line, moving him to the last position on the lead lap, which was 18th.
