In Pixar's Cars 2, which former oil baron secretly leads the Lemons criminal group?

Miles Axlerod secretly leads the Lemons criminal group in Pixar's Cars 2.

Axlerod is introduced as a former oil baron who has converted himself into an electric car. He creates the World Grand Prix and promotes Allinol, a new alternative fuel, while concealing a plan to discredit that fuel and cause international chaos.

The Lemons are a criminal alliance made up of historically unreliable or defective car models. Their plot uses electromagnetic weapons to make Allinol-powered racers explode, hoping the resulting disaster will turn the public against alternative energy.

Professor Zündapp is Axlerod's main collaborator and scientist, while Finn McMissile is a British intelligence agent investigating the conspiracy. Those characters are important to the plot but are not its hidden leader.
