In Pixar’s Cars 2, what is the name of the secret weapon used in the villains’ plan?

In Pixar’s Cars 2, the villains’ plan uses an electromagnetic pulse weapon.

The device emits electromagnetic pulses that disrupt the electrical systems of the cars targeted during the World Grand Prix. The villains use the weapon to make Allinol, an alternative fuel, appear dangerous, allowing them to profit from another fuel source and damage public confidence in the new product.

The plot borrows the language and structure of spy thrillers, where an electromagnetic pulse is commonly portrayed as a way to disable electronic equipment. In Cars 2, the weapon is adapted to the film’s all-vehicle world, so its victims are cars rather than human-operated machines.

The weapon is sometimes described simply as the electromagnetic pulse gun or EMP weapon. Those descriptions identify the same device, but the canonical concept is an electromagnetic pulse weapon. It is distinct from Allinol itself: Allinol is the fuel used in the racing plot, while the pulse device is the tool used to manipulate the race outcomes and public reaction.
