BYD’s Yangwang U9 Xtreme set a verified top speed of 496.22 km/h at Germany’s ATP Papenburg track on 14 September 2025. The run, driven by Marc Basseng, eclipsed August’s 472.41 km/h EV mark from the same venue. The U9X used a fresh set of GitiSport e.GTR2 Pro tyres developed with the Yangwang team for extreme EV loads and heat.
Giti Tire says the e.GTR2 Pro pattern was engineered to manage high mass and power from electric hypercars. The specification highlights include reinforced compounds, aramid fibre reinforcement, an anti-standing wave carcass, and fast warm-up additives validated in 500 km/h indoor tests. The tyre is certified to CCC/ECE regulations and positioned as a street-legal semi-slick.
The result surpasses prior verified production-car top speeds and underlines rapid EV performance progress. For tyre makers, thermal stability, standing-wave resistance and high-load construction are now critical at 300+ mph.
Yangwang’s limited-run U9 Xtreme uses a 1,200-volt architecture and four motors totalling around 3,000 hp. Media briefings note set-up changes for the attempt, including semi-slick tyres and aero-mechanical tweaks suited to Papenburg’s banking and straights.
“It is an honour to be here, in person, to witness this great milestone achievement for our valued partner, BYD,” said Andy Ng, General Manager for Original Equipment Manufacturing for Export Markets. “Giti is proud to have partnered with BYD for this project… We are committed to continuously pushing the boundaries of sustainable performance… and in building quality products that allow people to Enjoy Driving.”
