In Pixar's Cars 2, the final World Grand Prix race is held in London.
The World Grand Prix is a fictional international racing series created for the film. Its events take place in Tokyo, Porto Corsa, and London, with the London race serving as the climax after the spy plot reaches its most dangerous stage.
Lightning McQueen competes in the series, while Mater becomes entangled in an investigation involving secretly modified alternative fuel. The London setting lets the film combine recognizable landmarks with the franchise's vehicle characters and action-comedy style.
The event is often simply called the London race in summaries of the film. It should not be confused with the Piston Cup, the domestic championship central to the first and third Cars films. Cars 2 uses the World Grand Prix to give the story an international scale.
