In Pixar's Cars 2, what is the name of the German weapons expert allied with the villains?

In Pixar's Cars 2, the German weapons expert allied with the villains is Professor Zündapp.

Professor Zündapp is a small blue-gray car who helps develop and operate the equipment used in the plot against the World Grand Prix. His name and design reference the German Zündapp motorcycle company, which was founded in Nuremberg in 1917 and later produced motorcycles and other vehicles.

The character works with a group seeking revenge against the automotive world and is involved in the plan to discredit Allinol. His technical expertise makes him one of the story's principal antagonists, while Mater becomes entangled in the scheme after being mistaken for an American spy.

Professor Zündapp is not the same character as Miles Axlerod. Axlerod publicly organizes the World Grand Prix and presents Allinol as an alternative fuel, whereas Zündapp operates as a specialist within the conspiracy. Acer and Grem are henchmen associated with the villainous group.
