Continuity mistake: During the chase scene where they attach the "engine killer" remote to the Dodge M4S (aka Wraith's vehicle), 2 Chevy Malibu Cop cars are barreling up the road towards the racers. Once the cops pass the starting line, the cars are now Dodge cop cars. (00:44:25)
Revealing mistake: After Packard's car crashes with the Turbo Interceptor, his body is lying on the mangled car. If you look close enough you can see Packard's head moving slightly as if trying to hold still.
Continuity mistake: When the Wraith first shows at the drive in, Packard's car hood shows signs of the gunshots that the Wraith blows in his car, but that doesn't happen until a few minutes later in the film. (00:28:00)
Plot hole: Near the end of the movie, when Packard is about to race the Turbo, he puts on a helmet. Where exactly did he keep this helmet? The '77 Corvette is a two-seater with very little storage space for the passengers. Oggie and Minty's helmets could have been in the back seats of their cars.
Audio problem: When Oggie races the Turbo interceptor, the engine sounds for his car are from a V8, though his Chrysler Daytona is powered by a turbocharged 4-cylinder.
