Chinese automaker BYD’s luxury sub-brand YANGWANG has stunned the automotive world after its U9 Xtreme (U9X) hypercar set a new global speed record of 496.22 km/h on September 14, 2025, at Germany’s ATP Automotive Testing Papenburg track. The feat outpaced both the fastest petrol-powered model (490.484 km/h) and the previous EV benchmark.
This achievement showcases BYD’s growing dominance in electric mobility. Founded as a battery innovator, BYD has rapidly evolved into a global EV leader, and the U9X is a milestone that merges speed, technology, and sustainability.
The U9X builds on the U9 platform but introduces groundbreaking upgrades, including a 1200V high-voltage system, a Blade Battery with 30C discharge, and four ultra-high-speed motors producing over 3000PS. Combined with track-level tires and the DiSus-X suspension system, the car was able to reach unprecedented performance while maintaining zero emissions.
German racing expert Marc Basseng, who drove the U9X during the record run, credited the hypercar’s smooth electric power delivery for the flawless drive. BYD Executive VP Stella Li praised the R&D team, highlighting YANGWANG’s commitment to redefining automotive innovation.
The U9X will see a limited run of just 30 units, underlining its exclusivity and reinforcing its status as a collector’s dream.
