What fictional Arizona town does Pixar's Cars center on?

Pixar's Cars centers on the fictional Arizona town of Radiator Springs.

Lightning McQueen reaches Radiator Springs after accidentally leaving the road during a chase on Interstate 40. He damages the town's main road and is ordered to remain there while repairing it. His time with the residents changes his priorities before the Piston Cup race.

Radiator Springs is presented as a once-thriving Route 66 community. The arrival of Interstate 40 diverts traffic away from the town, leaving businesses and landmarks struggling. This fictional history reflects real Route 66 towns whose economies declined after newer highways bypassed them.

The setting includes Flo's V8 Café, the Cozy Cone Motel, Luigi's Casa Della Tires, and the courthouse. Cars Land at Disney California Adventure later recreated Radiator Springs as an extensively themed area, but the original town exists in Pixar's fictional world.
