Driver Marc Bessing completed the one-direction run on November 1 after two days of preparation on a closed section of Sheikh Khalifa Bin Zayed International Road. Road & Track reported that the FIA and Guinness World Records recognised the speed as the highest by a production car in a single-direction run.

Yangwang attributed the improvement over its earlier 496.2 km/h result to a revised rear-wing angle, suspension-software changes, adjusted tyre pressure and a specially developed tyre. The U9 Xtreme uses four motors and a 1,200-volt battery system.
