Background

Phoenix Raceway – also known as PIR – is a one-mile, low-banked tri-oval race track located in Avondale, Arizona. It is named after the nearby metropolitan area of Phoenix. The motorsport track opened in 1964 and currently hosts two NASCAR race weekends annually. PIR has also hosted the IndyCar Series, CART, USAC and the Rolex Sports Car Series. The raceway is currently owned and operated by International Speedway Corporation.

The raceway was originally constructed with a 2.5 mi (4.0 km) road course that ran both inside and outside of the main tri-oval. In 1991 the track was reconfigured with the current 1.51 mi (2.43 km) interior layout. PIR has an estimated grandstand seating capacity of around 67,000. Lights were installed around the track in 2004 following the addition of a second annual NASCAR race weekend.

Phoenix Raceway is home to two annual NASCAR race weekends, one of 13 facilities on the NASCAR schedule to host more than one race weekend a year. The track is both the first and last stop in the western United States, as well as the fourth and the last track on the schedule.

Race results

For the first time since 2013, the final race of the season was not won by the eventual Cup Series Champion. Instead, Trackhouse driver Ross Chastain, who was eliminated in the second round of the playoffs, wound up dominating the second half of the race to take the win, his second of the season and his fourth overall. As Ryan Blaney, who placed second, had the highest finishing position of the drivers who qualified for the Championship 4, he was declared the 2023 NASCAR Cup Series Champion.
