Continuity mistake: When Wrangler has finished tainting Champ's fuel supply, he proceeds to leave and bumps into a canister shortly after he begins to drive out. The canister falls directly forwards, and lands directly in front of his right headlight. Wrangler then continues to drive forwards, but the canister is now more to his side. (00:20:25)
Continuity mistake: When Cruise and Lugnut are first shown driving along the road, the shot from behind them driving over a hill shows their shadows cast behind them. It then cuts to a shot in front of them, where their shadows are now cast to their left. (00:03:55)
Continuity mistake: When Coupe is watching Wrangler race, the close-up shots of the television show a timer keeping track of how much time Wrangler spends on each lap. However, in the wide shots that show Coupe looking at the television, no timer can be seen. (00:11:45)
Revealing mistake: Cruise and Lugnut are driving home along a road after speaking with Mr. V8 and Coupe about the race. For the entire four minutes of this scene, the shadow of Cruise's wing mirror cast on the road passes under the road markings, when it should be cast on top of the markings. (00:04:00)
Continuity mistake: When Wrangler drives over the nails on the road, he comes to an abrupt stop. When he stops, the tyres are still positioned in the same place, but in the next shot, the tyres are suddenly dislodged and sticking out of the car, as a way of representing he has broken down. (00:30:25)
Continuity mistake: When Cruise and Lugnut are driving home on the road, there are road markings shown on the road that are about a foot long, with quite a thick paint job, but when Cruise starts to speed away from Lugnut later in the scene, the road markings are suddenly much longer, with a much thinner paint job. (00:04:00 - 00:05:35)
Continuity mistake: After Lugnut says "Pedal to the metal" and the Champ's mechanic says, "Come on, Cruise, come on", the scene cuts to Cruise and Wrangler on the race course. Wrangler is ahead of Cruise and Cruise is behind Wrangler, to his right. In the next shot, Cruise is suddenly directly behind Wrangler. (00:28:35)
Continuity mistake: When Lugnut goes to place the bet, he lifts the bag of money from the hook in his truck and moves it towards the betting window, with the bag of money still inside the hook. In the next shot, the bag of money is suddenly on the window of the betting booth, no longer in the hook. (00:17:35)
Continuity mistake: Lugnut picks up the race tickets that Cruise drops. He is first shown lowering the hook attached to his truck to the ground, but in the next shot, the tickets are suddenly inside the hook without the tickets being picked up by the crane. (00:11:30)
Revealing mistake: When Coupe says, "It's show time", the screen fades to black so it can transition to the next scene. Throughout the shot, before fading to black, Lugnut's wing mirror can be seen towards the left of frame, showing a very light greyish colour reflection. Just as the scene fades to black, an error in the animation can be noticed, where the reflection in Lugnut's wing mirror suddenly flickers to a much darker grey. (00:03:50)
Other mistake: When Wrangler is first seen, he is shown autographing tickets by driving over them. There is a tyre mark shown on the tickets when he first does it, but a few minutes later, when he autographs Cruise's tickets, there's no tyre mark on the tickets, even though he used the same method. Also, when Lugnut shows the tickets to the police car at the end, the tyre marks have now appeared. (00:08:05 - 00:11:15)
