In Pixar's Cars, Radiator Springs is inspired by America's historic Route 66.
The fictional town reflects the communities and roadside attractions that once depended on Route 66 travelers. When Interstate 40 bypasses Radiator Springs, the town loses traffic and much of its business, echoing the real economic changes experienced by many Route 66 towns.
Pixar artists and researchers traveled along Route 66 while developing the film. The journey helped shape the film's desert landscapes, diners, motels, signs, and small-town atmosphere. Radiator Springs is fictional, but its identity is rooted in real roadside history.
Route 66 originally connected Chicago and Santa Monica. It was removed from the United States Highway System in 1985, yet remains a major cultural symbol of American road travel and continues to attract tourists.
