Yang Wang, the luxury brand of China’s electric car company BYD, has managed to achieve a world record speed of 496.22 kmph at Germany’s ATP Automotive Testing Track.
The vehicle achieved this feat on 14 September 2025 with Yang Wang’s latest U Nine Extreme Hypercar, which became the world’s fastest car, surpassing its previous electric car record and the fastest petrol modern car record of 490.484 km/h.
According to the company, it is a new engineering milestone that combines unprecedented power and speed without any pollution.
It is important to note that the Koenigsegg Jesko Absolute has an estimated top speed of 330 mph (about 531 km/h), but this has not been formally recorded under the same conditions as the U-NineX. As such, the U-NineX is currently recognized as the fastest production car based on certified performance metrics.
The term ‘world’s fastest production car’ refers to a commercially available vehicle that has achieved the highest speed under verified experimental conditions. This means that the vehicle is produced in sufficient numbers to be sold to the public, not a unique prototype or custom car.
It was originally known as the Yu Nine Track/Special Edition, and is now known as the regular production Yang Wang Yu Nine Extreme or Yu Nine X for short. The car has been developed with several significant changes based on the technical structure of the U-Nine sold in China.
These improvements include a 1200-volt ultra-high-voltage electric powertrain (versus 800 volts), a lithium iron phosphate blade battery with a 30C super-discharge rate, four ultra-high-speed motors that rev up to 30,000 rpm and deliver a total of over 3,000 horsepower, track-suited semi-silk tires and DiSus-X suspension designed specifically for circuit driving. Designed to handle pressure.

BYD Executive Vice President Stella Lee said: ‘This is a proud moment for their team. Yang Wang is a brand that does not accept the impossible and this spirit makes a vehicle like the U9X possible. I would like to thank the whole team and driver Mark Bossing whose expertise made this car possible. The world’s fastest production car is now electric, it’s amazing.’
Driver Mark Bassing, a German track specialist with extensive experience in sports car racing and endurance motor support, said: ‘This record was only possible because of the incredible performance of the U-Nine Xtreme. This is technically impossible with a combustion engine. Thanks to the electric motor, the car is quiet, there are no load changes, which allows me to focus more on the track.’
The U Nine Extreme is now available to customers with a limited production run of only 30 units. Its name is derived from the English word ‘extreme’, meaning ‘extreme’ and ‘extreme’, with the addition of an ‘X’ to represent the unknown. All these characteristics are in line with Yang Wang’s philosophy.
By setting a new world speed record, Yang Wang has pushed the definition of sustainable hypercar to new frontiers. In keeping with BYD’s commitment to innovation and sustainability, Yang Wang uses the latest technology to deliver unparalleled performance, safety, and driving experience.
