Built in Spain and modeled after a Formula 1 racer and a fighter jet, the Tramontana is the latest in a long line minimal sports cars. Like the KTM X-Bow, the Tramontana is open-wheeled, seats one, and is ungodly fast. Packing a 5.5L V12 in its midsection that can pump out 720 hp, it's a monster. 2010 saw the brand make its American debut and, of course, Jay Leno was one of the first to take delivery.
