Shelby Supercars (SSC) has been making attempts to beat the record for the world’s fastest production car since March of this year. Well they have finally done it. Yesterday, SSC closed down a 2 lane stretch of public highway in Washington State to test the 1183 horsepower Ultimate Aero Twin Turbo.
Breaking the world record, while meeting the requirements set by Guinness, the Ultimate Aero TT averaged a top speed of 255.83 mph. Among the requirements set by Guinness” approval, a vehicle testing for the top speed record must race down the selected course, turn around, and make a second pass in the opposite direction within one hour. The vehicle”s “top speed” is calculated by taking the average of the top speeds of each pass.
The Ultimate Aero TT posted a top speed of 257.11 mph on its first pass and 254.55 mph on its second pass, averaging 255.83 mph. Of course, the folks at Guinness still have to verify the claim by SCC before the Ultimate Aero is officially named the “World”s Fastest Production Car.”
This breaks the current top speed record held by the Koenigsegg CCR at 242 mph and the Bugatti Veyron”s 253.
