SSC Ultimate Aero TT

America’s Shelby Supercars (SSC) is now officially the manufacturer of the ‘World’s Fastest Production Car’ thanks to its Ultimate Aero Twin Turbo supercar. The 1183hp (882kW) speedster set a new top speed record with an average Vmax of 255.83mph (411.76km/h), 3.11mph (5.01km/h) faster than the unofficial record set by the Bugatti Veyron. In order for the achievement to be official under the Guinness World Records’ guidelines, a vehicle testing for the top speed record must race down the course, turn around, and make a second pass in the opposite direction within one hour.
