The SSC Ultimate Aero has a top speed of 257 mph+ and can get from 0-60 miles in only 2.7 secs. It has Twin-Turbo V8 Engine with 1183 hp (horse power). But this beauty is definitely not free nor cheap; it has a base price of $654,400 (dollars). I wish I could afford that xD. Anyways, the SSC Ultimate Aero was tested in March 2007 by Guinness world records, thus taking the lead as the fastest car in the world (even beating the Bugatti Veyron!!!). Well, let us know what you think about it.
