What is the name of the villainous professor in Pixar's Cars 2?

The villainous professor in Pixar's Cars 2 is Professor Zündapp.

Professor Otto Zündapp is an eccentric German scientist and a leading member of the criminal plot behind the film's international racing events. He works with Miles Axlerod and uses a weapon that causes cars powered by Allinol, the film's alternative fuel, to malfunction violently.

Cars 2 shifts the franchise toward an international spy adventure. The story follows Lightning McQueen as he enters the World Grand Prix while Mater becomes involved with British agents Finn McMissile and Holley Shiftwell. Zündapp's name and design suggest a connection to German engineering and the historic Zündapp motorcycle company.

The character is voiced in English by Thomas Kretschmann. His plot helps expose the film's central deception: the apparent clean-energy promotion is being used to create public fear of alternative fuel and increase demand for conventional oil. Zündapp is ultimately arrested after the conspiracy is uncovered.
