Regarding a possible Cars 4, Cars 3 producers Kevin Reher and Andrea Warren told Cinema Blend that "If there's a good story to tell I mean our heads kinda break after having gotten this one done, like oh my God, what could you do the further adventures of? But like any sequel, from Toy Story 4 to Incredibles, as long as there's a good story to tell, it's worth investing; we do love these characters, we love them as much as the public does. " Regarding which character would be the main protagonist in the film, Reher and Warren stated that "if Cruz is a breakout character, kind of like Mater was", "she [would] be involved in a 4". Owen Wilson stated at a Cars 3 press event that possible stories have been discussed for a Cars 4, though he would personally like for a fourth Cars film to delve into aspects of the thriller genre, akin to Cars 2. In an interview with Screen Rant, Lea Delaria expressed interest in reprising her role as Miss Fritter while promoting the release of the short film Miss Fritter’s Racing Skoool with the Cars 3 DVD and Blu-ray release.
