2023 Production Alliance Group 300
The 2023 Production Alliance Group 300 was the 2nd stock car race of the 2023 NASCAR Xfinity Series, and the 24th iteration of the event. The race took place at Auto Club Speedway in Fontana, California, a permanent tri-oval shaped superspeedway. The race was originally scheduled to be held on Saturday, February 25, 2023, but due to constant rain showers, the race was postponed until Sunday, February 26, immediately following the Pala Casino 400 Cup Series race on the same day.
The race took the scheduled 150 laps to complete. John Hunter Nemechek, driving for Joe Gibbs Racing, dominated the final stages of the race, and earned his third career NASCAR Xfinity Series win, along with his first of the season. To fill out the podium, Sam Mayer, driving for JR Motorsports, and Justin Allgaier, also driving for JR Motorsports, would finish 2nd and 3rd, respectively.
This was also the final Xfinity Series race, and final race ever, to be held on the 2.0 mile version of Auto Club Speedway, as the track will be renovated into a 0.5 mile short track in the mid-2020's.
Background
Auto Club Speedway was a, low-banked, D-shaped oval superspeedway in Fontana, California which hosted NASCAR racing annually from 1997 to 2023. It was also used for open wheel racing events. The racetrack was located near the former locations of Ontario Motor Speedway and Riverside International Raceway. The track was owned and operated by International Speedway Corporation and was the only track owned by ISC to have its naming rights sold. The speedway was served by the nearby Interstate 10 and Interstate 15 freeways as well as a Metrolink station located behind the backstretch.Entry list
