In Pixar's Cars, which Piston Cup racer is sponsored by Dinoco?

The King is the Dinoco-sponsored Piston Cup racer in Pixar's Cars.

The King, whose real name is Strip Weathers, is an established champion and a respected figure in the racing community. His Dinoco sponsorship gives him the distinctive blue paint scheme and the prominent petroleum-company branding associated with the Piston Cup.

Dinoco becomes a major part of the film's plot because both Lightning McQueen and Chick Hicks want the company's sponsorship. The King is nearing the end of his racing career, while McQueen is an ambitious newcomer and Hicks is a longtime rival willing to use aggressive tactics.

A common mistake is choosing Lightning McQueen because Dinoco is closely connected to his future aspirations. McQueen drives for Rust-eze during Cars. The King is the Dinoco racer seen competing for the championship at the start of the story.
