Shelby Supercars-no relation to Carrol Shelby, producer of the Ultimate Aero Twin Turbo, is the world's fastest production car with a top speed of 255.83 mph. It beat the Bugatti Veyron by 3.11 mph and the Konigsegg CCR by 13.83 mph. The run was done on public roads in Washington state. The Chevrolet motor btw has 1183 hp and 961 ft. lbs. of torque and could spin the wheels in 6th gear at 190 mph!
Here's the story:
WEST RICHLAND, WA (SEPT 13, 2007) - Shelby Supercars (SSC), manufacturer of the ultra high-performance Ultimate Aero Twin Turbo, set the new 'World's Fastest Production Car' record earlier today with an average top speed of 255.83 mph. Confident of the 1183 hp vehicle's abilities, SSC set out to validate their top speed claim in accordance with the strict guidelines set by Guinness World Records. Among other requirements, in order to meet Guinness’ approval, a vehicle testing for the top speed record must drive down the course, turn around, and make a second pass in the opposite direction within one hour. The vehicle's official top speed is calculated by averaging the top speeds of each pass in order to negate any favorable road or weather conditions. Today, on a temporarily-closed two lane stretch of public highway in Washington State, the Ultimate Aero posted a top speed of 257.11 mph (413.83 kph) on its first pass and 254.55 mph (409.71 kph) on its return pass, yielding a new top speed record: a staggering 255.83 mph (411.76 kph). The data, collected by Dewetron's world-renowned GPS tracking system, will be verified by Guinness before the Ultimate Aero is officially crowned the ''World's Fastest Production Car.'' This breaks the current official record held by the Koenigsegg CCR at 242 mph by 13.83 mph and the Bugatti Veyron's unofficial speed of 253 mph by 3.11 mph.
