The first street race scene is supposedly a quarter mile race, taking approximately 10 seconds. However, the race takes almost two minutes of screen time and shows the vehicles driving in excess of 150 mph, faster than even a 1,200 hp Bugatti Veyron can accomplish a 1/4 mile.
At the house party, Dom says to Brian, "You can have any beer you want, as long as it's a Corona." This is a reference to automobile innovator Henry Ford. Although he probably never said, "You can have any color you want, as long as it's black," and although the Model T to which he was supposedly referring was made in several colors (including a couple of shades of green and red as well as gray, blue, and several others), the phrase has long been attributed to him, the Model T was not available in black during its first years of production.
The only cars to feature in both "Fast and Furious" films was Neal H. Moritz's navy-colored Ferrari F355, and Dom's RX-7. In the first film, the F355 was used in the Malibu race scene and then parked outside Verone's house in 2 Fast 2 Furious (2003). The RX-7 was changed and used again in the second film as Orange Julius' car in the first race scene.
The title rights, not the story rights, to the film The Fast and the Furious (1955), were purchased so that the title could be used on this project, another film about racing. The original film was shown in a theater owned by the grandfather of producer Neal H. Moritz.

After the filming of the crash at the end of the film, the same 1970 Charger wound up in the opening scenes of Herbie Fully Loaded (2005) as a car in the junkyard.
