The villainous professor in Pixar’s Cars 2 is Professor Zündapp.
Professor Zündapp is a German scientist who works with the film’s lemon cars to sabotage the World Grand Prix. He develops the electromagnetic device used to make Allinol fuel appear dangerous, helping the conspirators manipulate public opinion and advance their plan.
The character’s name is written “Zündapp,” including an umlaut, in English-language references to the film. He is voiced by Thomas Kretschmann. His appearance and name draw on German engineering and automotive associations, fitting the international espionage style of Cars 2.
Francesco Bernoulli is an Italian racing champion and Lightning McQueen’s on-track rival, not the villainous scientist. Hammond is the name of an American agent connected to the spy storyline, while McQueen is the franchise’s protagonist. These roles are separate despite the film’s large cast of talking vehicles.
