In Pixar's Cars 2, which villainous professor creates the lemon car plot?

Professor Zündapp creates the lemon car plot in Pixar's Cars 2.

Professor Zündapp is an internationally wanted German scientist who works with the criminal group of lemon cars. He helps develop the plan to use an electromagnetic pulse device against competitors in the World Grand Prix, creating chaos while discrediting Allinol, the alternative fuel promoted by Miles Axlerod.

The character is voiced by Thomas Kretschmann in the English version. His name and visual design evoke German engineering and espionage traditions, fitting the film's international spy-movie structure.

Professor Zündapp is often confused with Miles Axlerod, whose public role as an oil magnate and former racing car conceals his involvement in the conspiracy. Finn McMissile is a British intelligence agent who investigates the plot, while Acer is one of the henchmen rather than the mastermind.
