BYD's YANGWANG unveils U9 XTREME track edition with world speed record

Beijing (Gasgoo)- BYD's luxury new energy vehicle brand YANGWANG officially announced the name of the track-focused special edition of its all-electric supercar, which is named the U9 XTREME (U9X). The model is limited to just 30 units worldwide. Each vehicle will be individually customized.

The model follows its August engineering prototype that set a global EV top-speed record, and in September the U9X reset the benchmark with a 496.22 km/h run, surpassing all internal combustion cars to claim the world speed crown. It also recorded a 6:59.157 lap at Germany's Nürburgring Nordschleife.

The U9X sits on the world's first mass-produced 1,200V high-voltage platform and is powered by four 30,000-rpm electric motors delivering over 3,000 Ps, achieving a power-to-weight ratio of 1,217 Ps/t. Leveraging YANGWANG's "e⁴" power system and DiSus-X suspension, the car introduces real-time body attitude control to track scenarios, pushing beyond theoretical performance limits.

Upgrades include a reengineered cooling system with overall cooling capacity increased by 133%, a track-grade Blade Battery with 30C discharge rate and dual-layer cooling, and a titanium alloy–carbon ceramic braking package. The braking system was specially calibrated for the Nürburgring's 177 turns, enabling fade-free performance.

YANGWANG also collaborated with Giti Tire to co-develop the GitiSport e·GTR² PRO semi-slick, reinforced with aramid fibers to withstand speeds over 500 km/h. The tires feature asymmetric tread for cornering grip and wet drainage, and structural reinforcements for stability under extreme G-forces.
