Overview

• The U9 Xtreme reached 496.22 km/h at Germany’s ATP Papenburg test track with racing specialist Marc Basseng at the wheel.
• The speed was recorded in a single direction, so Guinness World Records certification remains pending under the two‑run average rule, with the SSC Tuatara still holding the official title at 455.28 km/h.
• BYD credits the result to a four‑motor layout producing over 3,000 CV, an ultra‑high‑voltage 1,200‑V architecture, a Blade LFP pack rated for 30C discharge, DiSus‑X suspension tuning and semi‑slick tires.
• The model, now confirmed for limited production as the U9X, will be capped at 30 units globally with pricing yet to be disclosed.
• This circuit‑focused variant differs from the U9 sold in China through weight‑reduction measures, revised aero and chassis setup, whereas the standard U9 makes about 1,300 CV and tops out near 309 km/h.
