In Pixar's Cars 2, what is the name of the villainous scientist behind the lemon cars' plot?

In Pixar's Cars 2, Professor Zündapp is the scientist behind the lemon cars' plot.

Professor Zündapp is an internationally wanted criminal scientist who works with the lemons, a group of cars associated with unreliable and historically unsuccessful vehicle models. His plan uses an untested alternative fuel and a powerful electromagnetic device to create chaos during the World Grand Prix.

The character is part of Cars 2's shift toward spy-film storytelling. Mater, Lightning McQueen, Finn McMissile, and Holley Shiftwell become entangled in the conspiracy as the races travel from Tokyo to Porto Corsa and London. Zündapp's name and design evoke a German engineering background.

Miles Axlerod is also central to the plot, but he is presented as a wealthy former oil baron and World Grand Prix organizer before his identity is revealed. Finn McMissile is a British spy, not the villain, while Acer is one of the lemon henchmen.
