Radiator Springs is the fictional town where Lightning McQueen must stay in Pixar’s Cars.
After damaging the town’s main road during a frantic escape, Lightning is ordered to repair it before leaving. His forced stay introduces him to residents including Mater, Sally Carrera, Doc Hudson, and Ramone.
Radiator Springs is presented as a once-thriving stop along the historic U.S. Route 66. The town’s decline follows the construction of Interstate 40, which diverts traffic away from the old road. This background gives the film its themes of slowing down and valuing overlooked communities.
The town is located in the fictional Carburetor County. Carburetor County is the wider county name, while Radiator Springs is the specific community and the franchise’s principal setting.
