This monster can hit a top speed of 257 mph, and boasts a 0-60 time of just 2.7 secs. It has a twin-turbo V8 Engine and a ridiculous 1183 horse power. Sure, the base price is a mind-numbing $654,400, but there are other (slower) cars on this list for much more. When the Guinness Book of World Records declared the SSC Ultimate Aero the fastest car in the world, car fans were shocked. The old standby Bugatti Veyron has finally been unseated.
