In Pixar's Cars 2, what is the real name of the villain Professor Z?

In Pixar's Cars 2, the villain Professor Z's real name is Professor Zundapp.

Professor Zundapp is a small German vehicle who works with the criminal plot behind the World Grand Prix. He helps develop the electromagnetic weapon used to manipulate the race cars' Allinol fuel and contributes technical expertise to the conspiracy.

The character is commonly called Professor Z because that name is used throughout much of the film. His full name, Professor Zundapp, is a more specific identification connected to the German Zündapp motorcycle and vehicle brand. He is voiced by Thomas Kretschmann.

Professor Zundapp works with Sir Miles Axlerod, whose public image as an environmental campaigner hides his role as the mastermind. He should not be confused with Finn McMissile, the British spy investigating the conspiracy, or Grem, one of its field agents.
