In Pixar's Cars, Luigi, the owner of Luigi's Casa Della Tires, is a Fiat 500.
Luigi is a small yellow Italian car who operates the tire shop in Radiator Springs. He is passionate about Ferrari racing and becomes especially excited when a famous Ferrari visits the town near the end of the film. His shop's name means “Luigi's House of Tires,” combining Italian language and automotive culture.
The Fiat 500, also called the Cinquecento, is an iconic compact car originally produced by Italian manufacturer Fiat. The classic version was introduced in 1957 and became associated with affordable urban transportation in Italy. Pixar used Luigi's proportions and styling to make his national identity immediately recognizable.
Luigi is often confused with Guido, his small blue forklift assistant. Guido is not a Fiat 500; he is a separate character who performs pit-stop tire changes and speaks very little English.
