In Pixar's Cars 2, the fictional seaside race location Porto Corso is meant to represent Italy.
Porto Corso hosts the second race of the World Grand Prix after the opening event in Tokyo. Its coastal architecture, harbor setting, winding roads, and Italian atmosphere distinguish it from the urban Japanese and British locations elsewhere in the film.
The race takes place around a picturesque Mediterranean-style course and forms part of Mater's increasingly complicated spy adventure. The location is fictional rather than a directly named real Italian city.
The name can cause confusion because “Porto” is also widely associated with Portugal, and Cars 2 uses invented places throughout its international story. In the film's setting, however, Porto Corso is the Italian stop on the World Grand Prix route, followed by the finale in London.
