Guido is the first name of the Italian forklift in Pixar's Cars.
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 assistant and close friend. Despite his modest appearance, Guido is an exceptionally skilled tire changer and dreams of performing a pit stop for a real race car.
That dream is fulfilled near the end of Cars when Guido changes all four of Lightning McQueen's tires with remarkable speed during the Piston Cup race. The sequence is a comic payoff to Guido's earlier excitement about racing and pit crews. His accomplishment also helps Lightning's team during the final competition.
Luigi is the yellow Fiat 500 who owns the tire shop, so the two names are easy to mix up. Guido's character name is also a common Italian given name, while his design and dialogue emphasize the film's playful international cast.
