In Pixar's Cars 2, which British spy car works with Mater to stop the Lemons?

Finn McMissile is the British spy car who works with Mater to stop the Lemons in Pixar's Cars 2.

Finn is an experienced field agent for the British government. He initially mistakes Mater for an American intelligence operative after seeing him at the World Grand Prix, and Mater's accidental observations eventually help expose the conspiracy.

The character combines classic espionage-film features with the visual language of a sleek sports car. Finn carries gadgets and weapons, but the story also emphasizes his surprise at Mater's unconventional methods and unexpected usefulness.

Michael Caine voices Finn McMissile. His partner is Holley Shiftwell, a fellow British intelligence agent voiced by Emily Mortimer. Together with Mater and Lightning McQueen, they uncover the plan involving Allinol and the Lemons.
