Porto Corsa hosts the second World Grand Prix race in Pixar's Cars 2.
Porto Corsa is a fictional Italian coastal city created for the film's middle racing event. The race winds through streets and waterfront scenery, contrasting with the neon urban course in Tokyo and the final circuit in London. Its architecture and coastline give the sequence a distinctly Mediterranean visual identity.
The World Grand Prix is presented as a three-race championship intended to promote Allinol, an alternative fuel developed by Miles Axlerod. Lightning McQueen competes in all three events, while Mater's accidental involvement with spies reveals that the races are connected to a larger conspiracy.
The other two venues are Tokyo and London. Keeping the locations in separate countries allows the sequel to combine international travel, recognizable visual environments, and action sequences without returning the story primarily to Radiator Springs.
