In Pixar's Cars, Lightning McQueen's Italian tire specialist is Luigi.
Luigi owns Luigi's Casa Della Tires in Radiator Springs and is an enthusiastic admirer of Italian racing. He is a yellow Fiat 500 and speaks with an Italian accent in the English-language version. His small shop is one of the town's landmarks, and his friendship with Guido connects him to the local automotive community.
Luigi is especially excited when Ferrari racing cars arrive in Radiator Springs near the end of the film. His enthusiasm for Ferrari is a recurring character trait, and the film uses it to contrast with the American stock-car world represented by the Piston Cup.
Guido is Luigi's compact blue forklift assistant and tire-changing partner. The two names are often confused because they work together and appear as a pair in many scenes. Luigi handles the tire shop and its conversation, while Guido is known for his exceptionally fast pit-stop skills.
Michael Wallis provided Luigi's voice. Wallis was also associated with Route 66 history and served as a consultant connected with the film's road-trip setting.
