The U9 Xtreme outdoes famous ICE models from hypercar manufacturer Bugatti, known for extreme hypercars. It is also more than 90 km/h faster than the Rimac Nevera, which tops out at 412 km/h.
BYD launched the standard Yangwang U9 in February 2024. A couple of months later, it was spotted being tested to reach speeds of 375 km/h, well above the original claim of 309 km/h. That car had a 960 kW quad-motor powertrain.
Then, in August 2025, details from China revealed that the U9 supercar has a hypercar variant about to launch, featuring about 2,220 kW from four 555 kW motors.
During the same year, the U9 Xtreme also set a lap time of 6 minutes and 59 seconds on the iconic Nürburgring track in Germany, making it one of the fastest cars around the ring.
