Overview
- The Yangwang U9 Xtreme reached 503.17 km/h (312.65 mph) on November 1, 2026, and the result has been recognised by the FIA and awarded two Guinness World Records for single‑direction production‑car speed.
- German racer Marc Basseng drove the runs on a closed 10 km section of Abu Dhabi’s E11 highway, with engineers making overnight aerodynamic, suspension and tyre changes after initial 490 km/h attempts.
- The car uses four independent motors on a 1,200‑volt electrical architecture that together produce just over 3,000 PS and runs bespoke high‑performance tyres developed with Giti Tire.
- Observers note the records are single‑direction only and that the Xtreme was tested in a special specification for the attempt, production is limited to about 30 customer cars, and a recent high‑speed test crash damaged another U9 Xtreme though the driver was reported unharmed.
- The run caps a staged development campaign that began in 2024 with incremental speed gains and signals how manufacturers are using limited low‑volume models as engineering showpieces and marketing halos while exposing questions about record methodology and customer parity.
