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. 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.
Continuity mistake: While Brian is running the Eclipse through the stadium parking lot, he shifts and the car jumps from 120 mph to 140 mph in about one second.
Continuity mistake: In the scene where Dom is pulling his red RX7 into the garage after the first race is broken up by the cops, he is making a right turn into the garage. When they cut to the front of the car pulling in the garage, his left signal light is on, meaning he made a left turn into the garage.
