Advanced Design Tramontana on Jay Leno's Garage – Click above to watch video after the jump

Jay Leno just keeps on living the car-obsessed dream. The comedian recently got a chance to hop into the cockpit of the Advanced Design Tramontana – answering the question about what would happen if you threw an Ariel Atom, KTM X-Bow and five kilos of cocaine into a blender and left it on for an hour or so. The car weighs around 2,700 pounds, which seems like quite a bit considering that there's a carbon fiber monocoque at the heart of this beast, but there's a surprise in the engine bay. A 5.5-liter twin-turbo V12 from Mercedes-Benz provides 750 horsepower to the rear wheels. The faint of heart can dial back the gusto to a more manageable 540 with the flick of a switch.

Advanced Design actually decided to plop an honest-to-goodness sequential six-speed gearbox behind that massive mill. Feel free to hop the jump to see the full clip from Jay Leno's Garage, complete with some very wild hair. It's cool, Jay. We won't judge.
