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)
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.
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.
