Trivia

 * First appearance of Dr. Cluckingsworth M.D.
 * First and only appearance of Speed Demon.
 * This is the 3rd time Donnie is under mind control.
 * Although this episode shares a similar name with the 1975 film Race with the Devil it has the same premise from the 1983 John Carpenter's horror film Christine, which is about a sentient and violent automobile of the same name.
 * The premise of the episode is also similar to Maximum Overdrive and The Car That Ate Paris which are also horror films about sentient cars.
 * The tires on the Turtle Racer reads "Good Enough Tires", as reference to Goodyear tires.
 * "Deadman's Curve" is the colloquial name given to any extremely dangerous hairpin turn on a US highway road.
 * Surfer Rock music plays on the radio while in the hippie van a reference to surfer music's popularity in the 60's
 * Surfer music also plays during the scenes with the Speed Demon and the human the speed demon possessed has hair and clothes similar to a stereotypical 60's car jockey.
 * The head of the Turtle Racer's lever highly resembles a Madball, a line of gross out monster toy balls from the mid 80's.
 * After Casey, April and Donnie get home, while souping up an old jalopy into a race car; Donnie and Casey go through an Insult Alphabet the same way their Live-action counterparts from the first TMNT Live-action movie do.
 * The roles of who calls who what are reversed though, as Donnie is the one that calls Casey "Barfaroni" in the series, where in the movie Casey is the one that Calls Donnie that.
 * The Cage Dr. Cluckingsworth sits in as the onboard Navigation system for the Turtle Racer looks like R2D2.
 * Case in point, Dr. Cluckingsworth's job as the Navigator is akin to that of an R2 Robot's job as copilot for a single-person star-fighter jet in the Star Wars Franchise.
 * The Turtle Racer resembles the Hot Wheels' Bone Shaker, with it's black body, silver front, opened top, and flames painted on the sides.
