What is the name of the Italian town visited in Pixar's Cars 2?

The Italian town visited in Pixar's Cars 2 is Porto Corsa.

Porto Corsa hosts one of the World Grand Prix races in Cars 2. The fictional location is presented as a picturesque coastal Italian setting, with narrow streets, waterfront scenery, and an atmosphere inspired by real Mediterranean towns. It forms the middle major location in the film's international racing itinerary.

The World Grand Prix begins in Tokyo and later reaches London, while Porto Corsa supplies the Italian stop between them. The race locations also provide the backdrop for Mater's growing involvement in the spy plot and for the film's emphasis on different national automotive cultures.

Radiator Springs is the fictional American town from the first Cars, and Carburator County is the fictional county associated with it. Santa Cecilia is not the Italian racing venue in the film. Porto Corsa is therefore the specific place name required by the question.
