In Pixar's Cars 2, which villainous professor creates the lemons' weapons system?

Professor Zündapp creates the lemons' weapons system in Pixar's Cars 2. He is an eccentric German scientist who works with the criminal group known as the lemons, a term used for cars considered defective or undesirable.

Zündapp develops the electromagnetic weapon that causes racers using Allinol to suffer dangerous engine failures. The plan is intended to discredit alternative fuel and benefit the criminals' interests. Mater discovers the conspiracy after being pulled into the spy plot involving Finn McMissile and Holley Shiftwell.

Eddie Izzard voices Professor Zündapp in the English version. He is not the same character as Sir Miles Axlerod, the public organizer of the World Grand Prix whose identity becomes a major plot reveal. The spelling includes an umlaut in Zündapp, although the name may appear without it in simplified text.
