In Pixar's Cars, what is the name of the rookie racer sponsored by Rust-eze?

In Pixar's Cars, the rookie racer sponsored by Rust-eze is Lightning McQueen.

Lightning McQueen begins the film as a talented but inexperienced stock car competing for the Piston Cup. Rust-eze, a company selling a product associated with rusty car maintenance, sponsors him before he becomes famous. The sponsorship is visible in the Rust-eze logo and yellow lightning graphics on his red body.

Lightning is voiced by Owen Wilson and is the film's central character. He is forced to confront his selfish attitude after damaging Radiator Springs and being ordered to repair the road. His relationships with Doc Hudson, Sally Carrera, Mater, and the other residents gradually change his priorities.

Rust-eze is sometimes confused with Dinoco, the prestigious sponsor associated with The King and later offered as a possible reward. Lightning's early sponsor is Rust-eze; Dinoco becomes part of the film's final racing decision and the franchise's broader sponsorship history.
