In Pixar's Cars 2, which spy car partners with Mater?

Finn McMissile is the spy car who partners with Mater in Pixar's Cars 2.

Finn is a British secret agent voiced by Michael Caine. He initially mistakes Mater for an American agent after Mater accidentally overhears information about a plot connected to the World Grand Prix. Their partnership becomes the film's central comic-spy storyline.

Holley Shiftwell, voiced by Emily Mortimer, is another British agent and becomes Mater's romantic interest. Professor Zündapp is an enemy scientist, while Francesco Bernoulli is Lightning McQueen's Italian racing rival, so all four names can appear in discussions of the film.

Cars 2 expands the franchise beyond Radiator Springs into an international adventure. Its races and espionage plot visit locations including Tokyo, Porto Corsa, and London, making Finn one of the series' clearest links to classic spy-film conventions.
