In Pixar's Cars, which fictional Arizona town is the film's main setting?

In Pixar's Cars, the fictional Arizona town that serves as the main setting is Radiator Springs.

Lightning McQueen reaches Radiator Springs after leaving the route of the Dinoco 400 and becoming separated from his transport truck. His accidental arrival begins the story's central relationship with the town's residents, including Mater, Sally, and Doc Hudson. The town is presented as a once-busy Route 66 community.

Radiator Springs is fictional, but Pixar based aspects of its appearance and history on real communities along U.S. Route 66. The film's story contrasts the town's quieter local life with interstate travel and modern racing culture. Radiator Springs should not be confused with Ornament Valley, the broader setting used in the Cars Land theme-park area.
