Overview

• German GT driver Marc Basseng piloted the U9 Xtreme at Germany’s ATP Automotive Testing Papenburg high‑speed oval for the verified run.
• The speed eclipses Bugatti’s 2019 Chiron Super Sport 300+ mark of 304.8 mph, though two‑way average benchmarks such as SSC Tuatara’s 282.9 mph remain under different criteria.
• Yangwang equips the Xtreme with a first‑in‑production 1,200‑volt platform, four electric motors delivering roughly 2,977–2,978 hp, and an LFP Blade battery engineered for ultra‑high discharge.
• Track‑specific hardware includes revised DiSus‑X active suspension and bespoke semi‑slick tires developed for sustained speeds near 500 km/h.
• BYD says production is capped at 30 units, and the car also logged a 6:59.157 Nürburgring Nordschleife lap, which is reported as the production‑EV record.
