Fillmore is the hippie Volkswagen bus character in Pixar's Cars.
Fillmore lives in Radiator Springs and operates a small organic fuel shop. His design is based on the Volkswagen Type 2, the classic van widely associated with the counterculture movement of the 1960s and 1970s.
The character's name refers to Fillmore Street in San Francisco, a location associated with music and counterculture history. Fillmore's relaxed personality and colorful paintwork reinforce that cultural reference.
Fillmore is voiced by George Carlin in the first Cars film. His neighbor Sarge, a military-style Jeep, frequently argues with him about politics, fuel, and lifestyle. That pairing supplies a recurring contrast between Fillmore's peace-oriented outlook and Sarge's disciplined, patriotic persona.
