In Pixar's Cars 2, who is the villain secretly operating the lemon cars' conspiracy?

Professor Zündapp secretly operates the lemon cars' conspiracy in Pixar's Cars 2.

Professor Zündapp is a German scientist who helps organize the plot to use electromagnetic pulses against racers using Allinol. The conspiracy is designed to make the alternative fuel look dangerous, allowing the lemon car community to profit while discrediting the World Grand Prix.

He is a small blue-gray vehicle modeled after a Zündapp Janus, a rare German microcar. Thomas Kretschmann provides the character's voice. Zündapp works with Sir Miles Axlerod, whose public role as the World Grand Prix organizer conceals his own involvement in the scheme.

Grem and Acer are henchmen rather than the mastermind, while Finn McMissile is an investigator. The film's plot intentionally mixes spy-thriller conventions with car-specific jokes and fictional technology. Cars 2 was released in 2011 and was the second feature-length film in the Cars franchise.
