What is the name of the villain in Pixar's Cars 2 who is also a scientist?

Professor Zündapp is the scientist villain in Pixar's Cars 2.

Professor Zündapp is an eccentric German scientist who works with Miles Axlerod's conspiracy. He develops the weaponized form of Allinol, the alternative fuel used in the World Grand Prix plot, helping the villains create dangerous explosions around the racers.

The character is a small, gray vehicle modeled after a Zündapp Janus, a German microcar produced in the 1950s. His name and design therefore connect the fictional villain to a real automobile manufacturer and model.

Miles Axlerod is the film's public-facing antagonist, while Finn McMissile is a British spy who opposes the conspiracy. Grem is one of the henchmen. These characters are often mixed up because Cars 2 combines espionage roles with racing characters.
