In Pixar's Cars 2, who is the British spy car partnered with Mater?

In Pixar's Cars 2, Finn McMissile is the British spy car partnered with Mater.

Finn is an undercover agent investigating a conspiracy connected to the World Grand Prix. After mistaking Mater for an American agent, he draws the tow truck into an international espionage adventure involving secret weapons, criminals, and a plot to discredit alternative fuel.

Finn's design combines traits associated with classic British spy vehicles, including a sleek body, hidden gadgets, and an elegant grand-touring profile. Michael Caine provides his voice in the English-language version, giving the character a deliberately polished contrast with Mater's comic personality.

Finn McMissile is not the film's villain. Miles Axlerod organizes the central conspiracy, while Professor Zündapp is one of its operatives. Finn's partnership with Mater forms the film's main buddy-spy pairing, even though Mater initially misunderstands the mission.
