What is the name of the race-car villain in Pixar's Cars 3?

The race-car villain in Pixar's Cars 3 is Jackson Storm.

Storm is a next-generation Piston Cup competitor whose advanced design, speed, and training threaten Lightning McQueen's place in professional racing. He represents a new era of highly optimized racers rather than the older generation that McQueen once dominated.

Armie Hammer voices Jackson Storm in the English-language version. The character's dark gray body, blue accents, and number 20 help distinguish him from McQueen's red number 95 car.

Chick Hicks is the principal rival in the first Cars, while Cal Weathers is a racer associated with the previous generation in Cars 3. Those characters are sometimes named when people remember the franchise's villains generally, but Jackson Storm is the specific antagonist of the third film.
