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.

Shelby Supercars (SSC), manufacturer of the ultra high-performance Ultimate Aero Twin Turbo, set the new 'World's Fastest Production Car' record with an average top speed of 255.83 mph. Confident of the 1183 hp vehicle's abilities, SSC set out to validate their top speed claim in accordance with the strict guidelines set by Guinness World Records.
This has therefore allowed the Ultimate Aero TT to attain a top speed of 255.83 mph over a two-way average with a peak one-way speed of 257.11 mph. What is interesting is that the record wasn't set at the Nardo high-speed bowl, the Ehra-Lessein VW test facility or even the Bonneville Salt Flats, the usual locations for record setting. No, SSC broke the record on a regular public road in Washington State that was cordoned off by police.
