Shelby Ultimate Aero named “Fastest Production Car” by Guinness World Records
West Richland, Washington – Guinness World Records has verified that it has named Shelby SuperCars’ Ultimate Aero the “Fastest Production Car” in the world. It marks the first time the production speed record title has been held by a U.S. auto manufacturer since the Ford GT40 claimed the title in 1967.
Guinness’ testing procedure required the car be driven down the course, turned around, and driven on a second pass in the opposite direction, within one hour. The vehicle’s official top speed was then calculated by averaging the top speed of each pass.
Driver Chuck Bigelow drove the car, clocking 415.31 km/h (257.45 mph) on the first pass, and 410.24 km/h (254.92 mph) on the second pass, for an official record speed of 412.28 km/h (256.19 mph). This breaks the current official record, held by the Koenigsegg CCR at 388 km/h and the Bugatti Veyron’s unofficial speed of 408.47 km/h.
The Ultimate Aero uses a twin-turbocharged V8 engine to produce 1,183 hp and 1,094 lb-ft of torque.
