Overview

• Driven by Marc Basseng on September 14 at Germany’s ATP Papenburg, the U9 Xtreme reached 496.22 km/h (308.4 mph), surpassing the Bugatti Chiron Super Sport 300+ benchmark from 2019.
• The result marks the first time an electric vehicle holds the fastest production-car title, according to multiple reports.
• BYD attributes the speed to a 1,200-volt platform, a high-discharge LFP Blade battery, and four high‑rpm motors delivering roughly 3,000 bhp in total.
• BYD plans a limited production run of 30 cars, with reports noting the record car used bespoke Giti semi‑slick tires and track‑specific hardware that may differ from customer vehicles.
• BYD also reported a Nürburgring lap time of 6:59.157 for the U9 Xtreme, with outlets noting the top‑speed figure has ATP certification and that broader independent validation remains a focus.
