Cars 2 features the London race that serves as the World Grand Prix finale.
The sequel’s international competition concludes in London, where Lightning McQueen races while Mater, Finn McMissile, and Holley Shiftwell work to stop the conspiracy surrounding Allinol. The city’s landmarks provide the setting for the film’s final major action sequence.
Cars 2 differs structurally from the original Cars because it combines racing with a spy thriller. Tokyo hosts the opening event, Porto Corsa hosts the second race, and London hosts the concluding event. This international route gives the sequel a much wider geographical scope.
Cars ends with the Piston Cup storyline and a return to Radiator Springs. Cars 3 returns to a primarily American racing context, culminating in the Florida 500. The London finale is therefore specifically associated with Cars 2.
