Which fictional highway town is the main setting of Pixar’s Cars?

Radiator Springs is the fictional highway town that serves as the main setting of Pixar’s Cars.

Lightning McQueen reaches Radiator Springs after accidentally leaving the road and damaging its main street. He is ordered to repair the road before leaving, and the work gradually connects him with the town’s residents.

The town’s design draws heavily on the landscapes, roadside businesses, and communities associated with historic U.S. Route 66. Characters such as Sally Carrera, Mater, Doc Hudson, and Ramone each represent different parts of the town’s identity.

Carburetor County is the fictional county containing Radiator Springs, not the town itself. That distinction makes Radiator Springs the specific answer when the question asks for Cars’ principal location.
