BYD’s Yangwang U9 Xtreme crashes during high-speed test ahead of 500 km/h attempt - Big Tech and the digital economy

A Yangwang U9 Xtreme reportedly left the track and hit a barrier during a high-speed test in China. The crash comes as BYD prepares a possible attempt to exceed 500 km/h in Dubai this month.

A Yangwang U9 Xtreme, the electric hypercar produced by BYD’s luxury brand, has crashed at high speed on a closed track in China. Images and video circulated in China on November 2 show the car leaving its trajectory and striking a barrier, reportedly tearing away the entire rear axle.

The test driver was reportedly able to leave the wreck without assistance and escaped without injuries, according to initial information relayed by CarNewsChina. The crash’s connection to BYD’s planned record attempt has not been confirmed, although the vehicle appeared to be undergoing a top-speed test near 500 km/h.

The U9 Xtreme reached 496.22 km/h at Germany’s Papenburg test track in September 2025, with German driver Marc Basseng behind the wheel. That result made it the world’s fastest production car, ahead of the Bugatti Chiron Super Sport 300+, which reached 490.48 km/h in 2019.

BYD is aiming to close the 3.78 km/h gap to the 500 km/h mark. In a July 6 interview with Business SNA, BYD executive vice-president Stella Li said the company was planning an attempt in Dubai in November. The proposed venue is a 15-kilometre road that must be identified and secured with the help of local police.

The U9 Xtreme is rated at 2,977 horsepower and uses 20-inch wheels fitted with GitiSport semi-slick tyres, along with an aerodynamic package featuring a large rear wing. At such speeds, however, the track surface, wind, tyre grip and braking distance are also critical factors.

The crash is significant for BYD because production of the U9 Xtreme is limited to 30 units. One example sold for more than 20 million yuan, or approximately 2.5 million euros, at the Beijing motor show in April 2026.

Despite the severity of the impact, the car’s passenger-protection cell reportedly remained intact. No fire or visible smoke from the battery pack was observed. The vehicle uses lithium-iron-phosphate battery chemistry, which BYD highlights for its thermal stability and reduced risk of fire under severe deformation compared with conventional lithium-ion chemistries.

BYD has not publicly confirmed the road, permits or date for the Dubai attempt. It is therefore unclear whether the damaged prototype will affect the company’s plan to pursue a speed above 500 km/h this month.
