In Pixar's Cars, Luigi is a Fiat 500.
Luigi owns Luigi's Casa Della Tires in Radiator Springs and is one of the town's most enthusiastic supporters of Italian automotive culture. His compact shape, expressive design, and admiration for Ferrari are built around the classic Fiat 500, a small Italian car that became a symbol of postwar mobility.
Luigi is voiced by Tony Shalhoub and speaks with an Italian accent. His assistant and friend Guido is a small forklift, and the pair provide both comic energy and tire-changing expertise. Luigi is sometimes mislabeled as a Mini because both cars are compact European designs, but the character's canonical model is the Fiat 500. His shop also helps connect the fictional town to real-world car traditions.
