What historic highway inspired the setting and road-trip atmosphere of Pixar’s Cars?

U.S. Route 66 inspired the setting and road-trip atmosphere of Pixar’s Cars.

Route 66 was established in 1926 and connected Chicago with Santa Monica, California. It became strongly associated with American road travel, roadside businesses, motels, service stations, and small communities. Much of the road was later bypassed by the Interstate Highway System, but its cultural importance continued.

Pixar filmmakers researched Route 66 during development of Cars. The fictional town of Radiator Springs reflects the decline experienced by many towns after faster highways diverted long-distance traffic. In the film, the town’s historic route and landmarks become central to its identity.

Cars is not a literal documentary about Route 66, and Radiator Springs is fictional. The inspiration is instead a blend of real landscapes, towns, businesses, and stories gathered during the filmmakers’ research. This is why fans often connect the film with specific Route 66 locations without treating any one town as the exact model.
