"Number 117, Ralph Carlow, is the little brother to famous Hollywood actor Jordon Carlow. The two brothers had little respect for what the other did for a living, but when Jordon got a role playing a race car in the film "Racing Hearts," he was forced by the studio to spend time shadowing his brother Ralph. After two long months of research, Jordon came away with a new respect for how hard racing really is, and after seeing his brother's performance in the film, Ralph gained a new respect for acting. Since then Jordon never misses a race and Ralph never misses a premiere."
He appears in the video game, but is renamed Lee Jr and has #101. He appears mostly in the front pack.
Ralph reappears in Cars 3. After the race at LAIS, he was replaced by a nexxt gen.
