In Pixar's Cars 2, what is the name of the international spy car who helps Mater?

In Pixar's Cars 2, the international spy car who helps Mater is Finn McMissile.

Finn McMissile is a British secret agent voiced by Michael Caine. He investigates a conspiracy connected to the World Grand Prix and initially mistakes Mater for an undercover American agent. Their partnership becomes central to the film's action-oriented plot.

Finn is designed as a classic espionage vehicle, with hidden gadgets, defensive equipment, and a refined Aston Martin-inspired appearance. He works with Holley Shiftwell, a British intelligence agent voiced by Emily Mortimer. Together, they try to uncover the plan behind the attacks on the World Grand Prix competitors.

Holley Shiftwell is sometimes selected because she is also a spy and has a major role in the same investigation. Professor Zündapp is an antagonist, while Miles Axlerod is the former oil baron whose public image conceals a larger part of the conspiracy.
