- Cowboy BeBop at His Computer: Several reference books have a character in the show called The General, as voiced by John Stephenson. There was a one-shot general in the episode "The Speedy Arkansas Traveler", but the only military personnel in the regular cast were Sgt. Blast and Private Meekly.
- The Goodwood Festival of Speed has built working replicas of all of the vehicles (minus the extraneous gadgets and hijinks, of course).
- This Brazilian commercial for Peugeot is not only clever but deadly accurate with character depictions. Muttley is the only CGI figure.
- Edited for Syndication: The original end credits had narration from Dave Willock playing over it, as well as a line from Dick Dastardly, explaining why Dick's mouth is seen moving in the music-only credits.
- Fountain of Expies:
- You'd be surprised how many Muttley clones there are. If not clones, there are those who mimic his signature laugh.
- Thanks to the legal issues regarding Heatter-Quigley, some of H-B's Mega Crossover series like Laff-A-Lympics couldn't use Dick Dastardly, forcing H-B to create the Dread Baron instead.note
- Market-Based Title: In Latin America (and Spain), the show is known as "Los Autos Locos" (lit.: The Crazy Cars); in Japan, it's called "Chiki Chiki Mou Race"; in France, the show's name is "Les Fous du Volant" ("The Crazy Drivers").
- Name's the Same: In Japan, Penelope Pitstop was renamed to Milk-chan...not to be confused with an anime character from decades later.
- The Other Darrin: Dick Dastardly is voiced by Jim Cummings in the Sega Dreamcast video game and the Wacky Races Forever pilot, due to Paul Winchell's death. Rob Paulsen has also apparently been in the role a few times.
- Role Reprisal: While most of the voices in the Dreamcast game are soundalikes, Janet Waldo and John Stephenson reprised their respective roles as Penelope Pitstop, and as Luke and Blubber Bear.
- What Could Have Been:
- Early on in production the show was meant to be more of a game show with kids as the contestants wagering on which Wacky Racer would cross the finish line first, the cartoon would than play, and whoever guessed correctly would get a prize but the quiz show angle was quickly dropped and instead aired the cartoon as it is.
- There was an attempted revival of the series in 2005 called Wacky Races Forever, but it quickly went under.
- Peter Perfect's car was called the Varoom Roadster in development, and the Ant Hill Mob's car was the Roaring Plenty. They were changed, obviously, to the Turbo Terrific and the Bulletproof Bomb, but their developmental names were retained for the Gold Key Comics run.
