In Pixar's Cars 2, which German scientist is a key member of the film's criminal conspiracy?

Professor Zündapp is the German scientist who is a key member of the criminal conspiracy in Pixar's Cars 2.

Professor Zündapp is a small yellow microcar and a major technical figure in the plot surrounding the World Grand Prix. He works with Miles Axlerod's organization and helps develop the equipment used to sabotage cars running on Allinol. His scientific role connects the spy storyline to the film's central conflict over alternative fuel.

The sabotage is designed to make Allinol appear dangerous when exposed to an electromagnetic pulse. Cars using the fuel are targeted during the races, creating explosions and chaos. The conspiracy is eventually uncovered by spies Finn McMissile and Holley Shiftwell, with Mater unexpectedly helping them.

Zündapp's name is a reference to the German motorcycle manufacturer Zündapp, which existed from 1917 to 1984. The character's nationality and design fit Cars 2's international espionage setting. He is sometimes confused with Axlerod, but Axlerod is the conspiracy's public-facing organizer and ultimate mastermind.
