London is the final World Grand Prix location in Pixar’s Cars 2.
The London race serves as the climax of the film’s international competition and spy adventure. Lightning McQueen competes while Mater, Holley Shiftwell, and Finn McMissile uncover the conspiracy surrounding the race, Allinol fuel, and the cars seeking to manipulate the event.
The setting uses recognizable London landmarks and streets, giving the finale a distinctly British atmosphere. The race is held after the earlier events in Tokyo and Porto Corsa, so London is the third and final World Grand Prix venue shown in the film.
London is sometimes confused with Porto Corsa because both locations appear late in the tournament narrative. Porto Corsa is the Italian stop, while London is the United Kingdom setting and the location of the final confrontation.
