BYD's Yangwang U9 Xtreme, the 2,977-horsepower electric hypercar that holds the production EV speed record, crashed during high-speed testing in China, with images of the wrecked car circulating on Chinese social media from November 2. The crash came just days before the car was due to make another attempt at breaking 311 mph (500 km/h).
Video and photos of the damaged car, surfaced by CarNewsChina, show the U9 Xtreme appearing to lose control on a closed track before hitting a barrier hard enough to tear the rear axle assembly completely away from the vehicle. BYD has not said how fast the car was travelling at the moment of impact, nor exactly what caused the loss of control.
Driver escapes without serious injury
Despite the violence of the impact, the test driver reportedly walked away without serious injuries and was able to climb out of the wreckage unaided. Photos show heavy damage to both the front and rear bodywork, but the passenger compartment appears to have remained largely intact, and there were no immediate reports of a battery fire.
That outcome points to the strength of the car's carbon-fibre-intensive safety structure. BYD says the regular U9 uses a "Super Carbon-Fiber Cabin" built for high torsional rigidity and occupant protection in a crash, and the same approach underpins the Xtreme. For a car capable of close to 500 km/h, keeping the survival cell intact in a barrier strike is the whole point of the design.
An established record holder
The U9 Xtreme is the most extreme version of BYD's U9 electric supercar. In September 2025 it reached 308.3 mph (496.22 km/h), a run BYD officially confirmed as the world's fastest production EV.
Its powertrain pairs four electric motors producing a combined 2,977 horsepower with a 1,200-volt electrical architecture and an 80.0-kilowatt-hour battery pack. Track-focused semi-slick tyres and a heavily revised version of BYD's DiSus-X suspension system complete the package. The four-motor e4 platform allows torque at each wheel to be controlled independently, the same basic technology behind the regular U9's party tricks, including its ability to jump and "dance", but tuned here for high-speed driving and cornering.
The 500 km/h run is still on the agenda
BYD has already confirmed it will take the U9 Xtreme back out for another high-speed run in the United Arab Emirates, aiming to beat its existing 308-mph mark and finally crack the 311-mph (500 km/h) barrier. Whether this crash affects those plans has not been announced.
The timing is awkward: a car built to chase a record just days later needs to be rebuilt before it can chase anything. The reassuring part is that the damage, however dramatic in photographs, appears confined to the bodywork and rear axle rather than the structure that protects the driver.
