Factual error: During the first race a square plate on the floor falls off Brian's Eclipse. The Mitsubishi Eclipse is a unibody car; the frame and body are built as one solid piece, and it does not have floor pans. While some racers might put a steel plate in the interior as a finishing piece, it would be cosmetic only and not part of the vehicle's structure.
Factual error: Dom makes fun of Brian after winning Brian's car in the first race scene. Dom says that Brian was "Granny shifting, not double-clutching like you should." Double-clutching is primarily used by truckers that don't have good synchros on their transmissions or road racers that need to match their transmission speed to the engine speed while downshifting through turns. Granny shifting is upshifting while revs are still low, a technique used to prevent traction loss with powerful torque cars (though it's rare and generally unnecessary). The writer, who is absent of any true racing or automotive knowledge, may have been thinking of power-shifting when he wrote Dom's lines, but the two types of shifting are NOT interchangeable and Dom saying such a thing is a mistake.

Continuity mistake: After the street race at the start, Leon alerts everyone that the cops are coming. While everyone is scattering you see a closeup of Brian running around to the door of his car and opening it, then a bird's eye view of his car with no-one near it. Then you see other people running and getting into their cars, then you see Brian run up to his car, open the door again and get in. (00:22:52)
Continuity mistake: At the first race when the cars are driving up to the start line to begin, the car furthest ahead is Brian's car (the green one), then it is Ja Rule's car (the red on with the yellow flames), the white car is third, and behind everyone is Dom's car (the red one). When the cars break at the start line, somehow the order of the cars reverses and Dom's car stops first while Brian's stops last and blows over the line. (00:16:18)
Revealing mistake: In the opening scene when showing the truck full of Panasonic goods, there are products to the ceiling on the left and right, but very little in the center. Trucks are always loaded uniformly to prevent load shift damage, especially the type that would have occurred during the hijack from the swerving side to side. (00:00:50)
Continuity mistake: When Brian pulls up in the warehouse alley in his Eclipse look at the car to his left. If it looks like Hector's car with no hood and the same chrome engine and graphics on the windshield, that's because it is. But when Hector says "That's mine." he points across the lot and the car is still next to them. (00:11:55)
Other mistake: At the climatic railroad grade-crossing scene towards the end of the movie, the black locomotive (A modernized EMD GP40) is moving entirely too fast for the track's curvature and the height of the rails. The track's rail are of light gauge, for yard rails and switching only. (You see the container yards in the background of the final scenes.) The camera shots also show a zig-zag curve in the railroad tracks - which would definitely be taken at a lower speed. You actually see the locomotive rocking at one point. Good dramatic movie scene - suicidal railroading. Furthermore, the locomotive's driver would have seen a sign for "grade crossing" ahead of the crossing and slowed his train down according to railroad regulations. He would have made two long blasts on his horns, a short and then a long - not a continuous tone as played back in the movie. When a grade crossing is just after a curve - there are severe speed restrictions in effect - 5mph or less - so there is a hope that the train can stop or slow down, should someone cross the tracks at the wrong time. The interior shot of the locomotives cab is wrong. The interior cab of a locomotive is not symmetrical. The old standard cabbed EMD's have two windows in the center where-as the interior shot only shows one center window. The locomotive's parked windscreen wipers are also not shown from the inside.

Factual error: In the first hijacking, one of the Honda Civics slips under the truck's trailer to avoid the road crew. Trailers with that much ground clearance do not exist, also trailers have a safety guard running the length of that space designed to prevent this very scenario from happening with a lower vehicle. The trailer has been modified to ride much higher than normal to make this stunt possible. The modifications to the lowered Honda are not sufficient to fit beneath an un-altered trailer.
