In Pixar's Cars 2, Professor Zündapp is the villainous scientist behind the World Grand Prix scheme.
Zündapp is a German compact car and an associate of Miles Axlerod. He develops the electromagnetic pulse weapon used by the villains to make participants in the World Grand Prix appear to crash while using Allinol fuel.
The character's name references the German Zündapp motorcycle company, which was founded in 1917 and later became known for small motorcycles and other vehicles. The film uses the name as part of its broader international spy-thriller setting.
Miles Axlerod is the public face of the conspiracy, while Zündapp supplies important technical expertise. Their plan is eventually exposed by Mater, Lightning McQueen, Finn McMissile, and Holley Shiftwell.
