Sterling

Sterling is the secondary antagonist of Cars 3.

He is a billionaire businesscar who purchased Rust-eze, after founders Rusty and Dusty Rust-eze put the company up for sale in order to build the Rust-eze Racing Center, an elite training facility with the latest technology. It appears that he also intends to run Rust-eze out of a personal office at the Racing Center. Sterling made his fortune as the 'mudflap king' of the eastern seaboard. While Lightning McQueen didn't know of him, Tow Mater did, stating that he does "make a quality mudflap at an affordable price."

Sterling proclaims himself to be a big fan of McQueen and is very knowledgeable of his racing career, including that of the racing career of McQueen's mentor, Doc Hudson.

After Tex bought Rust-eze he became in 2018 Crew Chief of Jackson Storm until the 2020 DInoco Light 350.
