BYD Yangwang U9 Xtreme breaks 500 km/h barrier
Published Date :
The Yangwang U9 Xtreme has reached 503.17 km/h on a closed highway in Abu Dhabi, setting two Guinness World Records for single-direction production-car speed and receiving official recognition from the FIA
Yangwang, BYD's ultra-luxury automotive brand, has raised the bar for production-car performance by breaking its own speed record. In September 2025, the Yangwang U9 Xtreme reached 496.22 km/h in Germany. Just over a year later, it has gone even further, becoming the first production car to cross the 500 km/h barrier with a recorded top speed of 503.17 km/h (312.65 mph). The record was achieved on 1 November 2026 along a closed section of Sheikh Khalifa Bin Zayed International Road (E11), in Abu Dhabi's Al Dhafra region. Behind the wheel was Marc Basseng, a Nürburgring 24 Hours winner and former FIA GT1 World Champion, who also drove the U9 Xtreme during its previous record-breaking attempt. The achievement followed two days of testing. After reaching 490 km/h on 31 October, engineers continued refining the car's aerodynamics, suspension settings and tyre pressures. The following day, Basseng successfully pushed the electric hypercar beyond 500 km/h.
Powertrain and performance
The Yangwang U9 Xtreme's ability to exceed 500 km/h comes from a four-motor electric powertrain, with an independent motor powering each wheel. Together, the motors produce 3,019 PS (approximately 2,977 bhp), while each can reach speeds of up to 30,000 rpm. The e4 platform's torque-vectoring system continuously adjusts power delivery to individual wheels to help maintain control at extreme speeds.
The hypercar also uses a 1,200V ultra-high-voltage electrical architecture, compared with the standard U9's 800V system. Its powertrain is supported by BYD's Blade Battery technology, which uses lithium iron phosphate (LFP) chemistry and supports discharge rates of up to 30C. The exact battery capacity of the U9 Xtreme has not been disclosed, although the standard U9 is equipped with an 80 kWh battery.
Managing stability at extreme speeds is BYD's DiSus-X intelligent suspension system. It makes independent adjustments at each corner to control body movement and maximise tyre contact with the road. The car also runs on specially developed Giti semi-slick tyres.
The U9 Xtreme has demonstrated its performance beyond straight-line acceleration, too. It recorded a Nürburgring Nordschleife lap time of 6 minutes 59.157 seconds, establishing a production electric-vehicle lap record.
Fastest production car in the world
With a recorded top speed of 503.17 km/h, the Yangwang U9 Xtreme has secured two Guinness World Records: the highest speed achieved by a production car and the highest speed achieved by an electric production car, both in a single-direction run. The achievement has also received recognition from the FIA.
But how does it compare with established names such as Bugatti, SSC and Koenigsegg?
The Bugatti Chiron Super Sport 300+ famously reached 490.48 km/h (304.77 mph) in 2019, becoming the first near-production hypercar to exceed 300 mph. However, the run involved a pre-production derivative rather than a standard customer-delivered vehicle.
The SSC Tuatara also attracted attention following early claims of speeds exceeding 300 mph. Those initial claims were disputed, but the car later recorded an independently verified two-way average of 282.9 mph (455.3 km/h) in 2021. It subsequently achieved a verified single-direction speed of 295 mph (474.8 km/h) in 2022.
Then there is the Koenigsegg Jesko Absolut, which was engineered with extreme top-speed performance in mind. Although Koenigsegg's simulations suggest it could potentially exceed the Yangwang's speed, the car has yet to demonstrate that capability in a verified top-speed attempt.
An important distinction is that the Yangwang's Guinness records recognise a single-direction run. This differs from conventional two-way average records, which account for factors such as wind and road gradient.
For now, the U9 Xtreme holds the recognised single-direction production-car speed record. Even if a combustion-powered rival eventually exceeds 503.17 km/h, the Yangwang will retain its electric production-car record until another electric vehicle surpasses it.
Beyond just the top speed
The achievement represents more than a milestone for BYD or driver Marc Basseng. It is also a significant moment for China's automotive industry and electric mobility, demonstrating how far high-performance electric vehicle technology has advanced.
For decades, the pursuit of outright speed records was largely dominated by established European and American hypercar manufacturers. Now, a Chinese electric hypercar has crossed a milestone that some of the industry's most prominent names have yet to achieve.
The record also brings greater attention to BYD and its ultra-luxury Yangwang brand. Exclusivity adds to the U9 Xtreme's appeal, with production limited to just 30 examples worldwide. Some customers are already finalising their specifications ahead of production.
Whether its record-breaking credentials will translate into higher collector values remains to be seen. However, its limited production run and place in automotive history could make the U9 Xtreme a particularly desirable addition to hypercar collections.
