Luigi, the tire shop owner in Pixar's Cars, represents Italy.
Luigi is a small yellow Fiat 500 who owns Luigi's Casa Della Tires in Radiator Springs. His design, name, Italian speech, and enthusiasm for Ferrari racing all connect him to Italy. He is especially excited when Ferrari race cars arrive in the film's finale.
The character is voiced by Tony Shalhoub, whose performance emphasizes Luigi's energetic personality and passion for motorsport. Luigi's closest friend and business partner is Guido, a small blue forklift who speaks very little but is an exceptional pit-crew assistant.
Luigi is not a generic European car: his Fiat 500 design is specifically associated with Italy. The film includes other internationally recognizable vehicles, but Luigi's national identity is one of his clearest character traits and becomes important during the Radiator Springs racing celebration.
