In Pixar's Cars, Guido, Luigi's assistant, is a forklift.
Guido works at Luigi's Casa Della Tires in Radiator Springs, where he helps service the town's vehicles. He speaks mostly in Italian and is especially passionate about racing. His dream is to perform a real pit stop for a racing champion, a goal that becomes important during the film's climax.
Guido is designed as a compact industrial vehicle, contrasting with the larger race cars around him. His small size and expressive movements create visual comedy, but the film also establishes him as highly capable. During the final race, he changes Lightning McQueen's tires with remarkable speed, proving that technical skill is not determined by physical size.
The character's name and workplace reflect the Italian identity of Luigi, who owns the tire shop. Guido's brief spotlight is one of the film's examples of how Radiator Springs' residents each contribute a distinctive talent to McQueen's success.
