London hosts the final World Grand Prix race in Pixar's Cars 2.
The World Grand Prix travels through three principal race locations: Tokyo, Porto Corsa, and London. The London event serves as the competition's finale and is tied closely to the film's espionage climax, with Mater and the secret agents uncovering the conspiracy behind the attacks.
The London setting includes recognizable landmarks and a nighttime race through the city. By this point, Lightning McQueen's racing challenge and Mater's spy storyline have become closely connected, bringing the film's two narrative threads together.
Tokyo is the opening venue, while Porto Corsa in Italy hosts the second race. Paris is not one of the three World Grand Prix locations in Cars 2, despite being a famous European city that might seem plausible in a globe-spanning competition. Remembering the order—Tokyo, Porto Corsa, then London—identifies the final venue precisely.
