The Desert Diamond West Valley Phoenix Grand Prix is a Verizon IndyCar Series race held at ISM Raceway in Avondale, Arizona. The open wheel racing in the Phoenix area dates back to 1915 on an oval soil at Arizona State Fairgrounds. The race was revived in 1950 by AAA, and then forwarded to the US Auto Club in 1956. USAC moved the race to the newly built Phoenix International Raceway in 1964. The race became a CART event in 1979, and joined the Indy League Race on in 1996. It was held continuously until 2005.
After a hiatus of eleven years, the race was revived by Verizon IndyCar Series in 2016. It is currently held on Saturday night under the lights. Long regarded as a popular Indy car track, Phoenix has a rich history of open wheel races, including a spectacular wreck involving Johnny Rutherford (1980), and a final career victory for Indy legend Mario Andretti (1993).
