What is the name of the hippie van character in Cars?

The hippie van character in Cars is named Fillmore.

Fillmore is a yellow-and-orange Volkswagen Type 2 microbus who lives in Radiator Springs. His appearance, free-spirited outlook, and references to peace, alternative living, and organic fuel identify him as the town’s hippie character. He operates Fillmore’s Taste-In, a small organic-fuel shop opposite Sarge’s surplus store.

Fillmore is voiced by George Carlin in the first Cars film. His relaxed attitude contrasts with Sarge, a military-themed green Jeep who strongly prefers order and discipline. Their neighboring businesses and opposing personalities create one of the movie’s recurring comic pairings.

Fillmore is sometimes confused with Mack because both are larger vehicles, but Mack is Lightning McQueen’s transport truck and hauler. Red is Radiator Springs’ shy fire truck, while Sarge is the town’s military-supply enthusiast. Fillmore returns in Cars 2 and Cars 3 with the other familiar residents.
