America’s Shelby Supercars (SSC) is 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.
On a closed stretch of highway in Washington State, the Ultimate Aero posted a top speed of 257.11mph (413.83km/h) on its first pass and 254.55mph (409.71km/h) on its return pass to set the new top speed record of 255.83mph (411.76km/h). The speeds were recorded using a series of satellites and several on board sensors, with independent firm Dewetron on hand to monitor progress.
Featuring a 6.8 liter twin-turbocharged V8 that redlines at 9,000 rpm and spits out a jaw-dropping 1,350 horses, the 2011 Shelby Supercars Ultimate Aero II has its sights set on taking back the street-legal speed crown currently held by the Bugatti Veryron Supersport.
The car weighs much less than the Veyron, helped in part by the world’s first one-piece carbon-fiber wheels that weigh less than 13 pounds. Carbon fiber is also spread Nutella-style all over the body, helping bring the car in around 2,600 pounds. The end result is a power-to-weight ratio that’s over double that of the Veyron.
