What is the name of the British spy car voiced by Emily Mortimer in Pixar's Cars 2?

Holley Shiftwell is the British spy car voiced by Emily Mortimer in Pixar's Cars 2.

Holley is an agent working for British intelligence and is assigned to the Tokyo operation involving Mater. She is equipped with spy technology and becomes an important partner in the film's espionage plot, which runs parallel to the World Grand Prix.

Her name combines a conventional first name with a mechanical pun, matching the naming style used throughout the Cars universe. She is also connected to Finn McMissile, the experienced British agent who recruits Mater for the mission.

Holley can be confused with Sally Carrera because both are female sports cars, but they serve different roles and appear in different story contexts. Sally is Radiator Springs' attorney, while Holley is an international spy introduced in Cars 2.
