BYD’s Yangwang brand has officially unveiled the U9 Xtreme, a track-focused electric hypercar previously known as the Yangwang U9 Track Edition. During an online launch event, the vehicle was tested at Germany’s Papenburg Automotive Testing Center in September 2025, achieving a top speed of 496.22 km/h (308.4 mph), making it the fastest production car ever recorded.
The Yangwang U9 Xtreme also completed a lap at the Nürburgring Nordschleife in 6:59.157, surpassing the Xiaomi SU7 Ultra’s electric production car record of 7:04.957. Production will be limited to 30 units for the global market.
The U9 Xtreme surpassed the Bugatti Chiron Super Sport 300+’s record of 490.5 km/h, while the Aspark Owl (438.7 km/h) lags significantly behind. Koenigsegg’s Jesko Absolut, though simulated, set a 0–400–0 km/h acceleration record in August 2025.
Based on the standard U9, the Xtreme features extended aerodynamic enhancements, including a larger carbon fiber front splitter, dual-channel hood design, and a swan-neck rear wing.
Measuring 4,991 mm long, 2,029 mm wide, and 1,351 mm tall with a 2,900 mm wheelbase, the car uses 20-inch dual five-spoke wheels paired with GitiSport e·Gtr2 Pro semi-slick tires, co-developed with Giti for speeds up to 500 km/h. Titanium calipers and upgraded ceramic carbon brakes handle stopping power.
The rear features a dual-layer diffuser, multi-layer rearview mirrors, and split taillights connected by the Yangwang logo. The interior boasts a fully digital instrument cluster, T-shaped center console with vertical touchscreen, and extensive use of carbon fiber and Alcantara. Bucket seats and a multifunction steering wheel emphasize performance.
Power comes from a quad-motor system utilizing BYD’s Yi Sifang technology on a 1,200V silicon carbide platform. Each motor generates 555 kW, totaling 2,220 kW (nearly 3,000 hp). This delivers a power-to-weight ratio of 1,217 ps/ton. Torque vectoring adjusts over 100 times per second, independently distributing power to each wheel.
The chassis integrates BYD’s DiSus-X active body control, using dual-valve suspension to adjust wheel vertical movement in real-time, enhancing traction during acceleration, braking, and cornering. The U9 Xtreme debuts a race-spec Blade Lithium-Ion Phosphate battery with dual-layer cooling, capable of discharging at 30°C for improved thermal management.
