Well it?s not officially official until Monday, but SSC (Shelby Super Cars) has just clocked a top speed of 411.76km/h (255.83 mph) in their imaginatively named SSC Ultimate Aero Twin Turbo. Using a turbocharged 6.2-litre V8, not only is it the fastest production car in the world, it is also the most powerful producing 882 kW (1183 bhp) and is claimed to be capable of reaching around 440kmh (273 mph).
In order to qualify for the Guinness Book of World Records, ?fastest production car world record?, contenders must race down the course, turn around, and make a second pass in the opposite direction within one hour. The vehicle's "top speed" is calculated by averaging the top speeds of each pass in order to negate any favourable road or weather conditions.
This effort surpasses the current record holder, Bugatti?s Veyron with a record top speed of 407.5 km/h (253.2 mph). Not bad for a car that has air conditioning, a navigation system, 10-speaker audio system, video/DVD screen, back-up camera and boot space, all as standard equipment!

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 race down the course, turn around, and make a second pass in the opposite direction within one hour.
The vehicle's "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 2 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 to set the new top speed record at a staggering 255.83 mph (411.76 kph). The data, collected by Dewetron's world-renowned GPS tracking system, and other checks 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 11.83 mph and the Bugatti Veyron's unofficial speed of 253 mph by 3.11 mph
