Cameos, in-jokes, re-used animation, and other trivia from Cars 3.
References to Cars
- A lot of the soundtrack in the film is recreated from the first film's soundtrack.
- The movie opens with a race at the Motor Speedway of the South.
- The Los Angeles International Speedway also reappears, this time as the track where McQueen had his fateful crash.
- The film includes early on a musical montage of Mack riding on the highway through various landscapes.
- The final race at the Florida International Speedway has many parallels to the tie-breaker race in Cars. Some of the most notable are Cruz Ramirez having to race past the pace car named Pat Traxson to enter the track, the surprise arrival of a crew chief (Doc Hudson in Cars, McQueen in Cars 3), and Cruz having to use a technique showcased by Doc earlier in the film to pass her rival racer.
- McQueen's crash mirrors the crash of The King (and by extension the crash of Doc Hudson) in the way he tumbles sideways on a considerable distance.
- When Mr. Drippy, the water truck at the Thunder Hollow demolition derby, falls on his side, he makes the same noise as the tractors when they tip over.
- The scene of Doc explaining the aftermath of his crash to McQueen is replayed in a flashback.
- After the final race, McQueen says about Cruz that "she's got a lot of stuff!" mirroring what Doc told McQueen following the tie-breaker race in Cars.
- The opening scene of the film mirrors the opening of the first movie. McQueen is saying his "Speed, I am speed!" routine from the first movie, accompanied with the same kind of cuts from black to racing cars.
- While in Thunder Hollow, McQueen says, "Turn right to go left!" twice, referencing his take on Doc's advice to McQueen about drifting. Also, just like McQueen in the original film, Cruz Ramirez doesn't understand what he means by this at first.
- Near the end of the movie when several next-generation race cars are being interviewed about the disappearance of McQueen, one of the racers, Ryan Laney, says, "Didn't he pull this when he was a rookie?" referencing the events of the first movie where McQueen got lost in Radiator Springs on his way to the Los Angeles International Speedway.
- At the end of the film, Cruz Ramirez jokingly calls Lightning McQueen an old man, like McQueen did with Doc Hudson at the end of the original film.
