In Pixar’s Cars, Luigi’s assistant is Guido.
Guido is a small blue forklift who works at Luigi’s Casa Della Tires in Radiator Springs. He speaks mostly Italian and is Luigi’s close friend and partner in the tire business.
Guido’s dream is to perform a professional pit stop. He gets that chance during the Piston Cup finale, when he changes all four of Lightning McQueen’s tires with remarkable speed. The sequence is a major comic moment because the tiny forklift outperforms the larger racing pit crews.
Luigi is a yellow Fiat 500 and operates the tire shop, while Guido handles tire-changing and other garage duties. The two characters reflect the film’s use of automotive culture, regional identity, and visual references to real vehicle types.
