In Pixar’s Cars 2, the second World Grand Prix race takes place in Porto Corsa.
Porto Corsa is a fictional Italian seaside city created for the film. Its race course runs through an environment inspired by Mediterranean coastal towns, with steep streets, water views, and historic-looking architecture. The location gives the international competition a visual identity distinct from Tokyo and London.
The World Grand Prix has three principal race venues: Tokyo is first, Porto Corsa is second, and London is the final stop. The competition is central to the plot because its alternative-fuel publicity campaign conceals a larger scheme.
Porto Corsa is not a real Italian city, although its name and scenery are designed to sound and look Italian. Radiator Springs is the fictional American town from the first film, while Carburator County is the surrounding county in Cars’ setting.
