Overview

• BYD says the U9 Track Edition reached 472.41 km/h on August 8, 2025 at the ATP test track in Papenburg with Marc Basseng at the wheel.
• The company describes the prototype as using four electric motors on BYD’s e4 platform delivering about 2,220 kW (3,018 hp) on a 1,200‑volt architecture.
• Aerodynamic and chassis changes included a carbon front splitter, semi‑slick Giti tires, and the DiSus‑X system that adjusts suspension around 100 times per second.
• Formal recognition has not been confirmed, and Guinness World Records still lists the 2024 Aspark SP600 run at 438.73 km/h as the standing electric‑car record.
• BYD has not clarified whether the Track Edition will be offered for sale, and combustion hypercars such as the Bugatti Chiron Super Sport 300+ remain faster overall.
