What model of car is Jackson Storm in Pixar’s Cars 3?

Jackson Storm is a custom-built next-generation Piston Cup racer in Pixar’s Cars 3.

Storm represents a new generation of competitors designed with advanced aerodynamics, data analysis, and modern racing technology. Unlike characters based closely on one famous production car, his appearance is a fictional competition design created for the Cars world.

He quickly becomes faster than many veteran racers, including Lightning McQueen. That contrast drives the film’s story: McQueen must decide whether experience can keep pace with younger racers whose training and equipment are built around highly measured performance.

Jackson Storm’s number is 20, and Armie Hammer provides his voice. He is often described informally as a futuristic race car, but that wording does not identify a single real-world make or model. The precise answer is that he is a custom-built next-generation Piston Cup racer, rather than a Hudson, Porsche, or production sports car.
