The Dark Knight's Tumbler
For the Dark Knight, a styrofoam model was made first and then 20 people set to work on it. Inside features a 5.7 liter 350 cubic inch engine pumping out 400 bhp. While people like to speculate that it's based off a Mercedes or Humvee, it's actually a totally unique custom creation. The Tumbler tops out at 100 mph!
