Highest speed achieved by a production car in a single-direction run

The highest speed achieved by a production car in a single-direction run is 503.17 km/h (312.65 mph), achieved by BYD (China), in a YANGWANG U9 Xtreme, driven by Marc Basseng (Germany), on a closed section of the E11 highway, in Al Dhafrah, Abu Dhabi, UAE, as verified by Fédération Internationale de l'Automobile (FIA) on 1 November 2026.

The BYD YANGWANG U9 Xtreme achieved a top speed of 503.17 km/h (312.65 mph) on a closed road in Abu Dhabi, setting Guinness World Records for the highest speed achieved by a production car (single direction) and the highest speed achieved by an electric production car (single direction). Exceeding 500 km/h marks a significant engineering milestone for a production EV and highlights the vehicle's high-performance capabilities.

These records relate specifically to peak speed in a single direction and should not be confused with conventional fastest-production-car records, which require different testing protocols, including runs in opposite directions. The speed was independently verified using the vehicle's onboard speedometer and a calibrated VBOX system, with an FIA representative reviewing the data and providing written confirmation to Guinness World Records as part of the verification process
