In Pixar's Cars 2, who is revealed to be the villain Professor Z's employer?

In Pixar's Cars 2, Miles Axlerod is revealed as Professor Z's employer and the film's main villain.

Axlerod presents himself as a former oil tycoon who has converted to electric power. He organizes the World Grand Prix, a global racing event intended to promote Allinol, a supposedly clean alternative fuel.

The conspiracy is designed to make Allinol look dangerous by causing race cars using it to malfunction near electromagnetic weapons. Axlerod's larger plan is to discredit alternative fuel and restore the influence of petroleum-based energy. Professor Z, a German weapons designer, works as his agent.

The twist is easy to miss because Axlerod initially appears to be a wealthy environmentalist and event organizer. His identity is exposed near the end of the film, after Mater connects the race incidents to the spy plot.
