Which villainous scientist is associated with the lemons in Pixar's Cars 2?

Professor Zündapp is the villainous scientist associated with the lemons in Pixar's Cars 2. He helps develop the plan to make Allinol appear dangerous and turn public opinion against alternative fuel.

Zündapp is a small German vehicle modeled after a Zündapp Janus, a real microcar produced in the 1950s. In the film, he works with the group of cars known as the lemons, whose members include vehicles from historically obscure or unsuccessful automotive brands.

The lemons use electromagnetic pulse weapons and manipulate the World Grand Prix to advance their scheme. Their plan depends on making the races look like proof that Allinol causes dangerous engine failures. Mater discovers parts of the conspiracy while trying to understand his unexpected role as a secret agent.

Zündapp is sometimes confused with Miles Axlerod, the apparent organizer of the World Grand Prix. Axlerod is the larger political and business figure behind the plot, while Zündapp is the scientist who helps execute its technical side.
