- "Respect the classics, man! It's Hendrix!"
- —Fillmore, after Sarge complains about his music being too loud.
In the first film, Fillmore is a 1960 Volkswagen bus with psychedelic symbols and liberal/environmental bumper stickers on his body (he's a hippie). Fillmore is a strong advocate of natural products and makes his living by selling organic fuel behind his neon dome, painted similarly to himself. His lawn is allowed to grow free with no mowing or pruning, and he also creates his own lawn ornaments from scrap. He believes that organic, renewable fuel would be more widespread were it not for a conspiracy involving the major oil companies controlling the government and supposedly not wanting to compete with Fillmore's cheap and plentiful fuel. Fillmore is a fan of Jimi Hendrix, and plays his version of the Star Spangled Banner every morning, much to the frustration of his neighbor Sarge. Despite their differences and frequent arguing, they appear to be close friends.
"Fillmore is Radiator Springs' resident hippie. A believer in individuality and all things natural, he brews his own organic fuel and preaches its many benefits. Visitors can try Fillmore's special flavors in the tasting room behind his love-bead and tie-dye-covered geodesic dome. His many conspiracy theories and "naturally" unkempt yard drive his neighbor Sarge absolutely crazy."
Radiator Springs’ resident hippie Fillmore is an easy-going, peace-loving 1960s Volkswagen van. And as his friend and neighbor Sarge likes to say, “once a hippie, always a hippie.” At his popular shop Fillmore's Taste-In, Fillmore brews his own fuel, which he sells with Bohemian accessories like tie-dyed mud flaps. But when he learns that the World Grand Prix will be run exclusively on the alternative fuel Allinol, Fillmore closes up shop and signs on as the fuel expert for Team Lightning McQueen.
When McQueen decides to partake in the World Grand Prix, Fillmore joins Mater, Luigi, Guido, and Sarge to be McQueen's pit crew, with Fillmore serving as the fuel expert. In the film, he is mainly seen with Sarge for most of the time, and comments on how the fuel Sarge eats in Italy is organic, much to his annoyance. Due to being a pacifist, Fillmore is not seen during the battle against the lemons in London. He does eventually rejoin his friends but gets scared when he sees British guards about to shoot McQueen and Mater (who has a bomb attached to him). In the end of the film, Fillmore reveals that, despite saying Sir Miles Axlerod's Allinol is safe during the Italy race, Sarge switches it out for his organic fuel.
Unlike Doc Hudson, who died in-universe following Paul Newman's death, Red, who became mute following Joe Ranft's death, and Rusty Rust-eze in Cars 3, who uses archived recording following Tom Magliozzi's death, Fillmore's voice actor is simply recasted in the sequel, with Lloyd Sherr replacing the deceased George Carlin.
Fillmore returns in Cars 3. He is voiced once again by Lloyd Sherr. Unlike the last two films, he only serves minor roles, and while he is seen serving as McQueen's pit crew in his races at the beginning and end of the film, he does not serve any roles apart from that. Oddly, when McQueen has his big crash, Fillmore (along with Sarge) does not go over to McQueen's crash site to check on him, despite Mater, Sally, Luigi, and Guido doing so.
Fillmore is very laid-back and tends to not take a lot of things seriously (with a few exceptions however, such as when Radiator Springs became completely deserted or when McQueen and Mater were on the verge of being shot at by the British gaurds). He has a hippie personality reminiscent of the 1960s, usually saying "man" at the end of his sentences. He loves nature, and tries to persuade the world in using organic fuel rather than major oils, with this obsessions causing Sarge to call him a "treehugger" in Cars 2 (though Fillmore calls him the same thing back at the end of the film). He is not always chill however, and has been seen angry a few times, such as in Cars when he sees McQueen enter the courthouse and calls him a "fascist" for destroying the road, or in Cars 2 when Mater embarrasses himself thanks to some wasabi in Tokyo, he, along with Luigi, Guido, and Sarge, were visibly angry that Mater made himself, along with the whole team, look bad.
- One of Fillmore's bumper stickers reads "Save 2D Animation." Another reads, "I brake for Jackalopes," a reference to Boundin'.
