Guinness World Records verifies 256.15 mph world record for a production car; first time production speed record has been held by a U.S. auto manufacturer since 1967
VISTA, Calif., Oct. 15, 2007 – HRE Performance Wheels (www.hrewheels.com), a leading designer and manufacturer of high-quality forged custom alloy wheels, today announced its wheels were used by Shelby Supercars (www.sscautos.com), manufacturer of the ultra high-performance Ultimate Aero Twin Turbo, when the world record was broken for the fastest production car.
Guinness World RecordsTM verified that Shelby SuperCars’ (SSC) Ultimate Aero is officially the “Fastest Production Car” in the world. This is the first time the production speed record title has been held by a United States auto manufacturer since the Ford GT40 claimed the record in 1967.
Shelby Supercars set out to validate their top speed claim in accordance with the strict guidelines set by the Guinness Book of 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.
The Ultimate Aero was outfitted with 19″ front and 20″ rear 897R HRE Performance Wheels custom manufactured to Shelby’s specifications.
“HRE Performance Wheels have been used to set many world records over the years and in the immediate past, and we are proud that Shelby SuperCars chose our ultra high-performance wheels to help them achieve this spectacular accomplishment,” said Evan Kinsella, president of HRE Performance Wheels. “We are looking forward to more incredible successes with Shelby.”
Guinness’ strict testing procedure required the car to drive down the course, turn around, and make a second pass in the opposite direction within one hour. The vehicle’s official “top speed” was then calculated by averaging the top speeds of each pass in order to negate any favorable road or weather conditions. Driver Chuck Bigelow, 71, drove SSC’s Ultimate Aero on a stretch of highway 221, clocking 414.31 kph (257.45 mph) on the first pass and 410.24 kph (254.92 mph) on the second pass to yield an official record speed of 412.28 kph (256.19 mph). From data presented by Dewetron’s world-renowned data acquisition system, Guinness officials verified the official speed to be .52 kph (.32 mph) faster than SSC had originally noted. This breaks the current official record held by the Koenigsegg CCR at 388 kph by 24.28 kph (15.09 mph) and the Bugatti Veyron’s unofficial speed of 408.47 kph by 5.84 kph (3.63 mph).
“Testing for the ‘World’s Fastest Production Car’ lends itself to many unknowns in the real world setting,” said Jerod Shelby, owner/manager of Shelby SuperCars. “Being the point of contact to the road, wheels and tires play as crucial of a role as aerodynamics and drive train capabilities. We were able to trust HRE with the task of building us wheels capable of this feat, and SSC couldn’t be happier with the performance, reliability and durability of the HRE wheels that are fitted onto each SSC Ultimate Aero.”
With 1183 bhp and 1094 ft-lbs of torque, the Ultimate Aero produces more emissions-legal horsepower than any other production automobile in the world (another Guinness World Record for which SSC is currently applying). Despite being designed to run at redline for extended periods of time, the Ultimate Aero remains remarkably drivable. The proprietary twin-turbo V8 power plant retains excellent idle characteristics, and thanks to a drag coefficient of just .357, wind tunnel testing calculates the vehicle to be aerodynamically stable to speeds up to 273 mph. Featuring all the amenities found in a luxury sedan, the supple leather/suede interior is highlighted by custom Recaro seats, a 10 speaker premium system, DVD/navigation/backup camera and a cab-controlled lift that raises the front an extra four inches to navigate road hazards.
