Answer: What is Phoenix International Raceway mean?

Phoenix Raceway is a 1-mile, low-banked tri-oval race track located in Avondale, Arizona, near Phoenix. The motorsport track opened in 1964 and currently hosts two NASCAR race weekends annually. Phoenix Raceway has also hosted the CART, IndyCar Series, USAC and the WeatherTech SportsCar Championship. The raceway is currently owned and operated by NASCAR.

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. It first joined the NASCAR Cup Series schedule in 1988 as a late season event, and in 2005 the track was given a spring date. The now-NASCAR Camping World Truck Series was added in 1995 and the now-NASCAR Xfinity Series began running there in 1999.

NASCAR announced that its championship weekend events would be run at Phoenix for 2020, marking the first time since NASCAR inaugurated the weekend that Homestead-Miami Speedway would not be the host track. The track will also hold the championship for the 2021 NASCAR Cup season.
