Boutique automaker unveils a 1,183-horsepower road rocket By Stuart Schwartzapfel Business Week updated 2:33 p.m. CT, Thurs., Jan. 24, 2008
On Sept. 13, 2007, the Shelby SuperCars' Ultimate Aero became the fastest production car in the world. The event took place on a temporarily closed, two-lane stretch of public highway in Washington State. In accordance with Guinness World Records' strict policies, the car had to drive down the highway, turn around, and make a second pass in the opposite direction within one hour.
The Ultimate Aero posted 257.41 mph on the first pass and 254.88 mph on the second for an average of 256.18 mph. Official data were collected via a GPS tracking system from Austrian data acquisition company Dewetron. Guinness World Records later verified data for an official top-speed announcement on Oct. 9, 2007. At that speed the Ultimate Aero broke the official record held by the Koenigsegg CCR (242 mph) and the unofficial record (253 mph) held by Volkswagen's $1.6 million Bugatti.
A nice picture and some specs at the link. List price only $600,000 but the car used for the test is reportedly the only one (of 50 planned for this model) ready for sale to a customer. Get your order in now!!!!
