What fictional Arizona town is the main setting of Pixar's original Cars movie?

Radiator Springs is the fictional Arizona town that serves as the main setting of Pixar's original Cars movie.

Lightning McQueen reaches the town after becoming separated from his transport during a journey to California. His attempt to leave quickly is interrupted when he damages the local road and must repair it under the town's supervision.

Radiator Springs is populated by characters including Mater, Sally Carrera, Doc Hudson, Luigi, Guido, and Fillmore. The town's decline is connected to the construction of Interstate 40, which bypasses the historic Route 66 community. That background reflects real changes experienced by towns along the old highway.

The setting is inspired by Route 66 landscapes and communities in the American Southwest. Radiator Springs returns in Cars 2, Cars 3, and other franchise stories as McQueen's home.
