Anyone trying to keep the timeline and pink slips of the Fast & Furious universe straight will have their head explode with this car. OK, now try and keep up.

At the very end of the third Fast & Furious movie (Tokyo Drift), Dominic Toretto shows up in "Hammer," the well-known 1970 Plymouth Road Runner built by Steve Strope's Pure Vision Design in Simi Valley, California. In the few lines of dialogue Toretto speaks, he explains he got the car from his friend "Han," who had been killed earlier in the movie.

So for the fourth film, Hammer had to come back. And miraculously, so does Han. But Hammer isn't owned by Han or Dom in this movie. Instead it's owned by Letty (Michelle Rodriguez). If you want to figure it all out, go ahead. Or, better yet, stop asking questions and enjoy the film.

In Tokyo Drift the real, exquisitely detailed, perfectly painted, hugely valuable Hammer was used as Dom's ride. However, since Hammer was going to be, well, hammered, in Fast & Furious, the production car department decided to build replicas. And the "real" Hammer doesn't actually appear in the fourth film at all.

The picture car department built three Hammer clones using two 1970 Plymouth Satellites and one actual Road Runner. Unlike the original Hammer, which is a pillarless hardtop, the three replicas were based on two-doors with pillars. To hide the pillars, they were simply painted black.

Both Satellites were totaled during production. The real Road Runner - running a 383 with a four-speed - was saved and is in storage. After all, who knows what time traveling is in store for Fast & Furious 5?
