In Pixar's Cars 2, which character is the secret agent Finn McMissile's partner?

Holley Shiftwell is Finn McMissile's partner in Pixar's Cars 2.

Holley is a British spy car who works with the experienced agent Finn McMissile. Their investigation concerns a conspiracy surrounding the World Grand Prix and a plot involving a new alternative fuel. Mater becomes entangled in the mission when Finn and Holley mistake his accidental behavior for deliberate espionage.

Holley is designed as a sleek blue-purple sports car with spy equipment and advanced gadgets. She is voiced by Emily Mortimer, while Michael Caine voices Finn McMissile. Their partnership gives Cars 2 its spy-film structure and moves the story beyond the small-town racing focus of the original movie.

Holley is sometimes confused with Sally Carrera because both are female Cars characters associated with Lightning McQueen. Sally is Radiator Springs' attorney and Lightning's romantic interest; Holley belongs to the international spy storyline in Cars 2.
