BYD builds the world’s fastest car

The fastest car in the world is now electric and comes from China! The Yangwang U9 Extreme, produced by the giant BYD, reached the astonishing top speed of 496.22 km/h, beating the previous record held by the legendary Bugatti Chiron Super Sport 300+. We are witnessing a historic shift in the hierarchy of high-speed automobiles.

For the first time, an electric vehicle has overtaken internal combustion engines in the race for speed supremacy. The Yangwang U9 Extreme surpassed the previous record of 490.47 km/h set by Bugatti in 2019 by 5.75 km/h. It should also be noted that this impressive result is due to its four electric motors which together generate almost 3,000 horsepower. In this article we will explore the technical details of this revolutionary supercar and its impact on the global automotive industry.

BYD breaks the world speed record with the YangWang U9 Extreme

The record was broken on September 14, 2025 at the ATP Automotive Testing circuit in Papenburg, Germany, where the YangWang U9 Xtreme reached an astonishing speed of 496.22 km/h (308.4 mph). The fastest car in the world thus surpassed the previous record of 490.48 km/h set by the Bugatti Chiron Super Sport 300+ in 2019 by 5.74 km/h.

At the wheel of the car was Marc Basseng, a German endurance racing driver, who said: «This record was only possible thanks to the incredible performance of the U9

YangWang U9 Xtreme, also known as U9X, represents the evolution of the U9 platform already present in the Chinese market. The car features a 1,200V high-voltage electrical system (up from 800V previously), a lithium iron phosphate battery with a discharge rate of 30°C, and four high-speed motors running at 30,000 rpm. Together, these engines deliver a total output of more than 3,000 hp.

The U9X also set a time on the Nürburgring Nordschleife circuit of 6:59.157 minutes. Production will be limited to just 30 units.

What technologies power the world’s fastest car

The technology behind the YangWang U9 Xtreme represents a revolution in the field of high-performance automobiles. The e4 platform is the first in the world to use a propulsion system with four high-performance engines that can reach 30,000 rpm. Each engine develops a peak power of 555 kW, and the power-to-weight ratio reaches 1,217 hp per tonne, placing the U9 among the elite of the global automotive industry.

The 1,200V system is the first mass-produced high-voltage platform, capable of improving power by 1,339% compared to conventional systems. Heat exchange efficiency is increased by 40%, allowing the battery to discharge at a rate of 30°C thanks to optimized cells and a new dual-layer cooling structure.

DiSus-Xthe intelligent body control system, is the first fully active body control system compatible with the 1,200 V platform. It makes rapid and independent adjustments to the vertical suspension during acceleration and aggressive cornering, effectively suppressing pitch and roll.

The independent torque distribution system continuously monitors road feedback, adjusting torque to each wheel more than 100 times per second. This maintains absolute control over the body’s posture, ensuring maximum grip even at extreme speeds.

Compared to combustion engines, the electric system offers distinctive advantages in high-performance applications, allowing the driver to concentrate better on the track, without load variations and with a reduced noise level.

How important this record is for the global automotive industry

The record set by the YangWang U9 Xtreme marks a watershed moment for the global automotive industry. BYD, the parent company, has demonstrated that electric vehicles are no longer just green alternatives, but leaders in the field of absolute performance.

BYD’s rise in the Fortune Global 500 to position 143 in 2024, up from 212 the previous year, reflects this manufacturer’s impact on the global stage. With annual revenue of 602.32 billion yuan, or an increase of 42%, the Chinese company is transforming global perceptions of the capabilities of Asian manufacturers.

In the UK, BYD reported an incredible 880% year-on-year growth in September 2025, establishing the country as the company’s largest market outside of China. Meanwhile, investment in research and development reached nearly 40 billion yuan in 2023, an increase of 97%.

Beyond the numbers, this speed record demonstrates that the future of the automotive industry belongs to electric innovation. Therefore, traditional manufacturers will have to rethink their long-term strategies. Furthermore, the success of the U9 Xtreme demonstrates that technologies developed for extreme performance vehicles will later influence mainstream models as well.

With currently more than 48,000 patent applications globally, of which more than 30,000 have been granted, BYD is redefining not only speed limits, but also the standards of the entire automotive industry.

Conclusion

Therefore, the Yangwang U9 Extreme completely redefines the concept of supercars for the 21st century. Its performance of 496.22 km/h is not only a new world record, but also marks the first time in history that an electric vehicle exceeds the limits imposed by internal combustion engines. Of course, this achievement would not have been possible without the revolutionary technical innovations of the e4 platform, the 1,200V high-voltage system and the four motors that together generate nearly 3,000 horsepower.

BYD demonstrates with this record that the future of high-performance automobiles belongs to electric technology. Furthermore, the company’s rise to the Fortune Global 500 confirms that we are witnessing a fundamental shift in the balance of power in the global automotive industry. Traditional manufacturers must now accept the reality: technical supremacy no longer belongs exclusively to established European brands.

The technologies developed for the U9X will undoubtedly influence future generations of electric vehicles, from advanced body control systems to batteries capable of extraordinary discharge rates. Thanks to these innovations, BYD not only set a new speed record, but opened a new chapter in the evolution of the automobile.

Ultimately, the Yangwang U9 Extreme’s record shows us that the limits of automotive performance continue to be pushed, but now in a completely new direction. Therefore, we are witnessing a historical moment in which China is not only participating in the global technology race, but is starting to set the standards for the entire automotive industry.
