Which Pixar character is the villain Professor Zündapp in Cars 2?

Professor Zündapp is also known as Professor Z in Pixar's Cars 2.

Professor Z is a small German-designed lemon car who works with the film's main villains. He is an inventor and scientific planner involved in the plot to discredit the World Grand Prix and manipulate the consequences of the race's alternative fuel.

The character's full name is Professor Otto Zündapp, while “Professor Z” is the shorter name used in the film and related material. His design and name reference the historic German Zündapp motorcycle company, giving the character an automotive-cultural joke beneath his villain role.

Professor Z is not the same as Miles Axlerod, the former oil magnate who presents himself as the organizer of the World Grand Prix. Zündapp acts as a technical collaborator within the conspiracy, while Axlerod occupies the larger public and political role. Finn McMissile and Holley Shiftwell investigate the plot.
