In Pixar's Cars 2, what is the name of the German weapons expert working for the Lemons?

Professor Zündapp is the German weapons expert working for the Lemons in Pixar's Cars 2.

Professor Zündapp, commonly called Professor Z, is a small gray Zündapp motorcycle who helps organize the conspiracy surrounding the World Grand Prix. He works with the criminal group known as the Lemons and uses sophisticated devices to disrupt racers and manipulate the public reaction to the race.

The character's name refers to Zündapp, a German manufacturer known for motorcycles. In English-language references, the name is often written with the umlaut as “Zündapp,” although some simplified listings omit the diacritic. Eddie Izzard provides the character's voice in the film.

Professor Z is sometimes confused with Miles Axlerod, who appears to be the sponsor and promoter behind the World Grand Prix. Axlerod is the conspiracy's public-facing figure, while Professor Z is its technical specialist and operational villain. Finn McMissile and Holley Shiftwell are agents investigating the plot rather than members of the Lemons.
