Which Pixar Cars film is set partly in London, England?

Cars 2 is the Pixar Cars film set partly in London, England.

London hosts the final race of the World Grand Prix, after earlier events in Tokyo and Porto Corsa. The London sequence also brings the spy plot to its climax, with Mater, Finn McMissile, and Holley Shiftwell confronting the conspiracy surrounding Allinol.

Cars 2 expands the series beyond the American settings emphasized in the original movie. It combines racing with international espionage and sends its characters to recognizable locations around the world.

The first Cars centers on Radiator Springs and the American Southwest, while Cars 3 returns to a more domestic racing story focused on Lightning's career. London is therefore especially associated with Cars 2, whose theatrical release took place in 2011.
