The 2018 DC Solar 300 was the 26th stock car race of the 2018 NASCAR Xfinity Series season, the final race of the regular season, and the inaugural iteration of the event. The race was held on Saturday, September 15, 2018, in North Las Vegas, Nevada at Las Vegas Motor Speedway, a 1.5 miles (2.4 km) permanent D-shaped oval racetrack. The race took the scheduled 200 laps to complete. At race's end, Ross Chastain of Chip Ganassi Racing would dominate, redeeming himself from the 2018 Sport Clips Haircuts VFW 200 to win his first ever NASCAR Xfinity Series career win and his first and only win of the season.[1] To fill out the podium, Justin Allgaier of JR Motorsports and Cole Custer of Stewart-Haas Racing with Biagi-DenBeste would finish second and third, respectively.
