* ActorAllusion: During the CreditsMontage, Mack (voiced by John Ratzenberger) is watching ''Cars''-universe versions of Pixar movies (including ''[[WesternAnimation/ToyStory Toy Car Story]]'', ''[[WesternAnimation/MonstersInc Monster Trucks, Inc.]]'', and ''WesternAnimation/ABugsLife''), and initially praises the voice actor for [[WesternAnimation/ToyStory Hamm Truck]] and [[WesternAnimation/MonstersInc the Abominable Snowplow]] [[ButHeSoundsHandsome (John Ratzenberger)]] ... but by the time ''WesternAnimation/ABugsLife'' rolls around, he [[LampshadeHanging realizes they're just reusing the same voice actor]] and [[SelfDeprecation criticizes them for it]].
** The King is voiced by Richard Petty, and is also modelled and painted after Petty's 1970 Plymouth Superbird. He is described as having won seven Piston Cups - which is also the number of Winston Cup Championships that Petty won in his racing career (he is also the only seven time winner of the Daytona 500). And his wreck at the end of the film appears to be nod back to Petty's wreck in the 1988 Daytona 500.
** In the US version, Jeremy Piven is the voice of [=McQueen=]'s agent Harv. Piven is known for his role as Hollywood superagent Ari Gold on the HBO series {{Entourage}}. Meanwhile, the UK version uses JeremyClarkson, known for his part in the Creator/{{BBC}} series ''Series/TopGear''.
** Don't forget Mater's "I don't care who you are, that's funny right there", and "Git-r-done!", both of which are Creator/LarryTheCableGuy's {{Catchphrase}}s. It's so much that Mater's Voice is actually credited as "Larry the Cable Guy", not "Daniel Whitney".
** A variant of this: [[spoiler:Chick Hicks goes to victory lane after he intentionally crashes the King on the last lap of the final race (which would lead to him being black-flagged in real life) and is pelted with old tires and booed off stage]].
*** It's similar to backlash that was made against Rusty Wallace after he spun out Darrell Waltrip on the last lap of the May 21, 1989 NASCAR Sprint All-Star Race at Charlotte Motor Speedway and sent Waltrip into the grass. As Wallace claimed the victory and the $200,000 prize, fans booed, gestured rudely and pelted the track with beer cans, while a dispute on pit road quickly escalated into a twenty-five person fistfight, to which Waltrip said, "I hope he chokes on the $200,000, that's all I can tell him. He knocked the hell out of me. I guess I made a big mistake by letting him get up there too close to me in the first place." Two of the people associated with that All-Star Race are in this film: Darrell Waltrip (as Darrell Cartrip), and the speedway's operator, Humpy Wheeler (who voices Tex, Dinoco's owner).
* ActorSharedBackground:
** Junior, voiced by {{NASCAR}} star Dale Earnhardt, Jr., is based on the Chevrolet Monte Carlo that the real-life Earnhardt drove in the Cup Series from 1999 to 2006.
** Mario Andretti, voiced by the racing legend of the same name, is based on the 1967 Ford Fairlane that the real-life Andretti drove to victory in the 1967 [[{{NASCAR}} Daytona 500]].
** Michael Schumacher, voiced by the multiple UsefulNotes/FormulaOne champion himself, is a Ferrari F430. The real-life Schumacher won five of his seven [=F1=] drivers' titles with the Ferrari team.
** Strip "The King" Weathers, voiced by NASCAR legend Richard Petty, shares many characteristics with his voice actor. (1) Weathers is portrayed as a 1970 Plymouth Superbird, the car that Petty drove at that time. (2) He is painted in Petty's distinctive shade of blue and bears the number 43 that Petty drove for his entire NASCAR career. (3) Weathers won seven Piston Cup titles; the real-life Petty won the same number of Cup Series titles. (4) Weathers' crash at the end of the tiebreaker race is very similar to one in which Petty was involved during the 1988 Daytona 500. However, artistic license was taken—the real-life crash involved six cars in all, and was not deliberately caused.
** The King's wife Lynda, voiced by Richard Petty's real-life wife Lynda, is based on the 1974 Chrysler station wagon that she drove to Richard's races in the 1970s.
* TheDanza: Guido voiced by Guido Quaroni.
* DoingItForTheArt: Pretty much the movies in a nutshell. A good majority of the staff like cars. So why not make a movie around them with the usual Pixar charm.
* FakeNationality:
** Lebanese-American Tony Shalhoub as Luigi. This may be an ActorAllusion to his role as an Italian cabdriver on ''Series/{{Wings}}''.
** Shu Todoroki's voice actor is American.
* HeyItsThatVoice
** Lightning is [[Film/{{Zoolander}} Hansel]] and Mater is Creator/LarryTheCableGuy.
** Some say that you can only hear him in the UK version, and that he plays Lightning [=McQueen=]'s Agent Harv. All we know is, he's called [[TopGear Jeremy Clarkson]].
** And speaking of car show cameos, Click and Clack of radio's ''CarTalk'' make cameos as [[TheAllegedCar alleged cars]].
** Let's not forget the [[ExactlyWhatItSaysOnTheTin Michael Schumacher Ferrari]].
** What about '''[[Creator/MichaelKeaton the goshdarn Batman]]''' as Chick Hicks?
** The King himself, Richard Petty.
** Sheryl Crow sings the intro song "Real Gone" during the opening credits - and also makes a cameo as a camper van while singing.
** Oh, and that really ''is'' Creator/TomHanks, Tim Allen, Dave Foley, Billy Crystal, and John Goodman reprising their past {{Pixar}} roles in the drive-in scene.
** George Carlin as Fillmore, doing his Hippy Dippy Weatherman voice.
** In the Japanese version, [[VideoGame/KingdomHeartsII Tron]] / [[Series/NinjaSentaiKakuranger Ninja Blue]] / [[Anime/{{Pokemon}} Professor Sycamore]] is Lightning [=McQueen=].
** Lampshaded in the credits - John Ratzenberger, who's been in every single Pixar film to date, plays Mack. During the end credits, Mack goes to a drive-in featuring ''[[WesternAnimation/ToyStory Toy Car Story]]'', ''[[WesternAnimation/MonstersInc Monster Trucks, Inc.]]'', and ''WesternAnimation/ABugsLife''. Mack [[ButHeSoundsHandsome praises John Ratzenberger's characters]] at first, until he realizes...
--->'''Mack:''' [[HypocriticalHumor Wait a minute here... they're just using the same actor over and over!]] [[SelfDeprecation What kind of a cut-rate production is this?!]]
* InMemoriam: This film was dedicated to Creator/JoeRanft, a prominent Pixar animator and voice actor (e.g. Heimlich in ''WesternAnimation/ABugsLife'') who died in a car accident in 2005. ''WesternAnimation/CorpseBride'' was also dedicated to Ranft.
* RealitySubtext:
** The King's crash is based, frame by frame, on an ''[[http://www.youtube.com/watch?v=vi-0SIQsGY8 actual crash]]'' Richard Petty lived through in the Daytona 500. Though the real crash involved Petty and at least six other cars.
** Doc Hudson is largely based on 2-time NASCAR champion Herb Thomas, who, in fact, won his two titles in a Hudson Hornet. There are minor differences between the two, namely [[spoiler:their ultimate fates]], Doc Hudson is Thomas in car form.
** The Motor Speedway of the South is loosely modeled off of Charlotte Motor Speedway in North Carolina, where the movie was premiered, and bits are based on "Thunder Valley" - Bristol Motor Speedway. The California speedway where the finale happens does not exist, but it is possibly a substitute for Fontana's Auto Club Speedway.
* TalkingToHimself: Mama Topolino shares her actress with the Queen.
* WriteWhatYouKnow: Aside from his passionate love of automobiles (his father owned a car dealership, which he worked at during the summer), the moral of slowing down and appreciating the important things in life came from John Lasseter taking time to go on a vacation with his family down the real Route 66 after spending four years making ''ABugsLife'' and saving ''ToyStory2'' from {{Sequelitis}} status with no break in-between. The juxtaposition of the workoholism and the wife and children he loved gave him his own lesson in "slowing down."
