American manufacturer Shelby Supercars (SSC) is claiming to have set a new record for the "World's fastest production car" at 255.83mph.
If verified by Guinness World Records, that would officially make the Ultimate Aero TT quicker than the Bugatti Veyron. The Veyron has a claimed top speed of 253mph, though this has never been officially verified by Guinness.
The Ultimate Aero TT achieved its potentially record-breaking run on a closed section of public road in Washington State, US, on 13 September.
In accordance with Guinness World Record regulations, the SSC team made two runs, one in either direction. The car reached 257.11mph on the first run, and 254.55mph on the return, making an average of 255.83mph.
The previous record-holder is the Swedish-made Koenigsegg CCR, which hit 242mph.
