In Pixar's Cars, Luigi’s vehicle manufacturer is Fiat.
Luigi is a yellow 1959 Fiat 500 who runs Luigi’s Casa Della Tires in Radiator Springs. He is an enthusiastic tire expert and a devoted admirer of Ferrari racing cars. His small, rounded shape and Italian identity make him one of the film’s most recognizable supporting characters.
The Fiat 500, commonly called the Cinquecento, was introduced in 1957 as a compact city car designed for postwar Italy. Luigi’s model is the original rear-engined 500, not the modern Fiat 500 introduced in the twenty-first century. The character’s name and Italian accent reinforce the connection.
A frequent mistake is answering Ferrari because Luigi celebrates Ferrari and later meets Michael Schumacher in the film’s epilogue. Ferrari is the marque Luigi admires; Fiat is the manufacturer represented by Luigi himself. Guido, his assistant, is a small forklift rather than another Fiat 500.
