Cars 2 is the Pixar Cars film set partly in London with a major race there.
The film's World Grand Prix concludes in London, where the competitors race through a stylized version of the city. Famous landmarks, including Big Ben and Buckingham Palace, appear in the movie's international setting.
Cars 2 expands the series beyond Radiator Springs and traditional stock-car racing. Lightning McQueen competes in the World Grand Prix, while Mater becomes involved with British spy cars Finn McMissile and Holley Shiftwell. The plot combines racing with an espionage adventure.
Cars, the first film, focuses mainly on the American towns and roads surrounding Radiator Springs. Cars 3 returns to a more personal racing story centered on Lightning's career and his rivalry with Jackson Storm. Thus the London race specifically identifies Cars 2.
