Fillmore is the Volkswagen Type 2 bus and organic-fuel advocate in Pixar's Cars.
Fillmore runs a small organic-fuel business in Radiator Springs and promotes alternative fuel to the town's residents. His design is based on the classic Volkswagen Type 2, commonly associated with the counterculture movement of the 1960s and 1970s. The character's name is a reference to San Francisco's Fillmore district and its cultural history.
George Carlin voiced Fillmore in the original Cars, and Lloyd Sherr voiced him in later Cars productions after Carlin's death. Fillmore is often confused with Sarge, the military-style green jeep, or Ramone, the lowrider who operates a body-art shop. His organic-fuel advocacy is a character trait, not the film's central racing premise.
