In Pixar's Cars, the fictional Arizona town inspired by Route 66 is Radiator Springs.
Radiator Springs is the main setting for much of the 2006 film. Lightning McQueen reaches it after leaving the interstate and accidentally damaging the town's road. A court order requires him to remain there and complete repairs.
The town reflects the history of U.S. Route 66, whose roadside communities declined after interstate highways redirected traffic. Pixar artists and filmmakers researched Route 66 locations while developing the movie, using desert landscapes, roadside businesses, and historic attractions as visual inspiration.
Radiator Springs is located in the fictional Carburetor County. The town's residents include Mater, Sally Carrera, Doc Hudson, Luigi, Guido, and Flo. Ornament Valley is a nearby fictional landscape, not the town itself, while Wheel Well is a separate location mentioned in the Cars universe.
