In Pixar's Cars 2, the British spy's surname is McMissile.
Finn McMissile is an experienced British intelligence agent who investigates a conspiracy connected to the World Grand Prix. He recruits Holley Shiftwell and eventually becomes involved with Mater, whose accidental observations help expose the plot.
The character is designed as a classic secret-agent car, with hidden weapons, gadgets, and an advanced spy-car appearance. His name combines the Scottish-sounding prefix “Mc” with “Missile,” signaling both his British identity and his action-oriented role.
McMissile is sometimes confused with Miles Axlerod, the former oil baron who presents the World Grand Prix, or with Francesco Bernoulli, Lightning's Italian racing rival. Those characters are central to the story but are not the British spy. Finn's full name is Finn McMissile.
