Pixar’s Cars 2 features three World Grand Prix locations.
The race takes place in Tokyo, Porto Corsa, and London. These locations give the sequel a distinctly international structure and allow the story to move from Japan to Italy and then the United Kingdom. Each setting has its own visual identity, track design, and surrounding action.
Tokyo hosts the first race, where the competitors use a temporary street circuit. Porto Corsa, a fictional Italian coastal location, provides the second race. London hosts the final event, which is intertwined with the film’s spy plot and its climactic confrontation.
The three locations are sometimes counted incorrectly because Cars 2 also includes other places where characters travel or conduct missions, including Radiator Springs and airports. Those are story locations, not World Grand Prix race venues. The question refers specifically to the official race locations shown in the championship.
