Piston Cup racer
Sheldon Shifter is a Next-Generation Piston Cup racer who takes over the Sputter Stop sponsorship at the beginning of the 2017 season, replacing the previous racer Murray Clutchburn. His racing number is 92.
In Cars 3, after next-generation racers begin to receive attention as a result of their higher capabilities, Piston Cup teams begin replacing their veteran stock racers with next-gen racers. Sheldon replaces Murray Clutchburn as the Sputter Stop racer. He makes his debut in the Florida 500. Throughout the race, he can be seen racing alongside the next-gen Rev-N-Go racer. In the crash, Cam Spinner hits him. Sheldon spins out of control and careens toward the infield. Later, he can be seen entering his pits safely. He restarts toward the back of the pack, and later gets imagined as a tractor by Cruz Ramirez. Sheldon later passes Ramirez again. He disappears for the rest of the race and finishes in twenty-seventh place.
- In the movie, he has a brown spoiler, but on his die-cast, the color of his spoiler is green.
- During the crash, his face can be seen as blank.
- Sheldon could be a possible relative of Megan Shifter.
