They're at it again. The folks at Shelby SuperCars (SSC) are about to take one more crack at the record books. They have just released a statement saying that they hope to hold the official title of "World's Fastest Production Car" by the end of the month. SSC has done all the paperwork to make sure that when it does in fact take to the track, the Guinness Book of World Records people will be satisfied with the results. That meant getting a suitable venue (in Washington) and using suitable methodology to perform and record the runs. The 1,183-horsepower SSC Ultimate Aero TT already topped 241 mph during shakedown evaluations, almost beating the official record of 242 held by the Koenigsegg CCR, but is ultimately shooting for the Bugatti Veyron's 253 mph unofficial top speed.

Full press release after the jump. We'll keep you posted on the results after the record attempt is made.

WEST RICHLAND, WA (1 Aug 2007) - Shelby SuperCars (SSC), manufacturer of the world's most powerful production car, the Ultimate Aero TT, announced today that speed testing for the title "World's Fastest Production Car" will be finalized by the end of August. Speed testing is being conducted in the company's home state of Washington and is being validated by Guinness World Records.

There is a standard procedure outlined by Guinness World Records to validate a land speed record. The vehicle must drive the predetermined course, turn around, and drive back the opposite way within one hour. This is to negate any discrepancy there may be in the course or conditions. Top speeds from each run are then averaged to obtain the official speed. This method has been used for decades as the benchmark for land speed record attempts.

Dewetron, a company known for performance testing of missile, train, aerospace, and automotive capabilities will accurately monitor and measure the speed of the Ultimate Aero TT for the record run. Dewetron's equipment is precise that Guinness World Records approved their systems as a replacement for the standard 1,000m laser traps. Dewetron utilizes 4-12 satellites and numerous onboard sensors to track a vehicle's speed.

The lack of access to a US-based proving ground able to accommodate the Ultimate Aero TT's top speed presented SSC with a massive challenge. After scouring the country for months, SSC found the solution in their home state of Washington when they were granted the opportunity to close public highways for testing. Finding appropriate roads eligible for closure proved to be a tedious process as SSC's teams scouted the sites first hand. After a potential site was identified, the company would need to apply for a road closure permit. Hiring police, a crew to man the closed section, and securing insurance for the high-speed test sessions were just a few of the undertakings necessary to be granted the rare closure of public roads.

Since the first test session, SSC has successfully concluded several rounds of high-speed safety and durability testing for each assembly of the Ultimate Aero TT. During these sessions, SSC was able to verify all the engineering specifications as well as aerodynamic data posted at NASA's Langley wind tunnel. Throughout the test sessions, the measured top speed of the Ultimate Aero TT continued to rise, achieving a speed of 241.4 mph at a throttle position of only 71% during the latest transmission durability test. After reviewing all test data, Jerod Shelby and the SSC engineering team feel comfortable in maximizing the capabilities of the 1183 hp Ultimate Aero TT.
