China’s BYD tops Bugatti’s 304.77-mph mark with a 496.22-km/h electric hypercar

From China with speed

For decades, the fastest cars in the world came from Europe or America, with names like Bugatti and SSC dominating the headlines. Now, a new challenger has risen from an unexpected place.

BYD, a Chinese automaker best known for affordable EVs, shocked the world with its YangWang U9X hypercar. According to BYD, this all-electric monster reached 308.4 mph (496.22 km/h) at Germany’s ATP Papenburg on Sept 14, 2025.

With this single run, China made its mark on the world stage of supercars. It’s a powerful reminder that innovation can come from anywhere, even outside the traditional automotive capitals.

3,000 horsepower unleashed

When you press the accelerator in the YangWang U9X, you’re commanding power unlike anything most people will ever experience. This electric hypercar has four separate motors, each working to create mind-blowing performance.

BYD reports the system delivers 2,220 kW peak output (2,959 hp; BYD describes this as 3,000 PS), depending on conversion, positioning the U9 family among the most powerful production car powertrains to date. That much power is usually reserved for rockets, not road cars.

With instant electric torque, the U9X launches forward like it’s defying physics. It’s proof that EV technology isn’t just about efficiency; it’s about showing how far performance can be pushed in the modern driving age.

Beating Bugatti’s big number

In 2019, Bugatti stunned the world when the Chiron Super Sport 300+ hit 304 mph. That was the gold standard for years, a number nobody thought could be topped so soon.

The YangWang U9X went further, clocking 308 mph in Germany. A Chinese EV just outpaced one of Europe’s most respected hypercars. The shift is more than just numbers on a speedometer; it represents a turning point in automotive history.

Speed has a new home, and it doesn’t wear a French badge. Instead, it’s powered by silent electric motors and groundbreaking battery technology.

The catch with records

There’s one reason BYD’s achievement isn’t official yet. The run must be done twice in opposite directions to make a record valid. This ensures things like wind and track slope don’t give unfair advantages.

Many record authorities and lists require a two-way average for wind/gradient; BYD’s run was one-way. By that two-way standard, the SSC Tuatara’s 282.9 mph (455.3 km/h) two-way average from Jan 2021 remains a commonly cited production-car benchmark.

A skilled driver at the wheel

You don’t just hand over a 3,000-horsepower car to anyone. BYD chose Marc Basseng, a German racing driver with decades of experience, for this record attempt. His steady hands were crucial to keeping the U9X on track.

As the car hit its top speed, onboard footage shows it running very close to the left-side barrier; Basseng later said he could likely have stayed on throttle longer.

At that speed, even the smallest correction takes incredible skill. Basseng stayed calm and pushed the car as far as he could. Without him, the U9X might not have reached its astonishing top speed or made history in Germany safely.

A near miss at 500 km/h

When the speedometer climbed past 308 mph, the U9X still had more to give. Many believe it could have reached the magic 310 mph mark, equal to 500 km/h.

But just as it was getting there, Basseng had to back off. The car drifted toward the barrier, and safety came first. It was a dramatic moment, showing both the raw power of the machine and the razor-thin margin for error. While it didn’t quite hit 500 km/h this time, the U9X proved it has the potential to get there on a future attempt.

Not just about straight lines

The YangWang U9X isn’t built to go fast in a straight line. It’s also proving itself on the toughest track in the world, the Nürburgring Nordschleife in Germany.

Yangwang also announced a Nordschleife lap of 6:59.157, a sub-7-minute lap time the company published alongside the Xtreme unveiling. Beating a circuit like Nürburgring means more than horsepower; it’s about control, balance, and handling.

With this record, BYD showed the U9X is more than a speed machine. It’s also a finely tuned driver’s car capable of handling twisting corners at insane speeds.

A world-first battery system

The U9X doesn’t just stand out because of its speed. BYD says U9X is the first series-produced car with a 1,200-V platform. That’s a huge leap from the 800-volt setups found in many modern EVs.

Higher voltage means more power can be delivered instantly while reducing heat and weight. The result is faster acceleration and a battery system that doesn’t overheat under stress.

For a car built to hit nearly 500 km/h, this kind of advanced battery tech isn’t optional; it’s necessary. It’s another example of how BYD is rewriting the rules of electric performance.

Regenerative braking power

At incredible speeds, stopping a car safely is just as important as making it go fast. The YangWang U9X handles braking in a revolutionary way by using regenerative systems.

Reporting from Top Gear cites peak energy recuperation of >700 kW; BYD hasn’t published a detailed public spec with that exact figure.

Suspension from the future

At nearly 300 mph, even the smallest bump can be dangerous. BYD’s DiSus-X active body control system adjusts damping, ride height, and torque distribution well over 100 times per second, helping preserve tire contact and control at very high speeds.

This system constantly adjusts stiffness and torque to keep the car stable. BYD marketing materials say DiSus-X can minimize roll and even target ‘zero or negative roll’ in specific scenarios; independent validation is limited.

That means better control at insane speeds and smoother handling for drivers. It’s like giving the car super reflexes, letting it react faster than any human could to sudden changes on the road.

Tires built to survive speed

Tires are often the weakest link in speed runs, with extreme forces threatening to tear them apart. The car used GitiSport e·GTR2 Pro semi-slicks developed with Yangwang for extreme speeds; media noted rim knurling and high-viscosity lubricant to reduce tire-rim slip.

These tires are designed to keep a tight grip, even at speeds approaching 500 km/h. They also minimize slippage between the rim and rubber, a common issue when huge power is involved.

Without these custom-built tires, the record run would have been impossible. They’re a reminder that going this fast isn’t just about engines and motors; every component works perfectly together.

A price that shocks rivals

You might expect a hypercar this powerful to cost millions. The standard Yangwang U9 launched in China at 1.68 million RMB; U9 Xtreme production is limited to ≤30 units, with pricing undisclosed.

This aggressive pricing shows BYD isn’t just making a statement about speed; it’s also about accessibility. By offering such performance at a fraction of the price, the company is making high-end electric performance something far more people can dream about owning.

China’s giant leap forward

Not long ago, Chinese car brands were seen mostly as budget options. BYD is producing a car that outpaces the best from Europe and America. That’s a massive leap in just a few years.

The YangWang U9X shows how fast China’s auto industry has grown. With massive investment in EV technology, the country is no longer following trends; it’s setting them.

BYD’s success proves that China isn’t just competing with established brands like Bugatti and Tesla; it’s beating them at their own game. This speed record is a turning point for global car culture.

Electric tech is evolving fast

A decade ago, many doubted electric cars could ever compete with traditional hypercars. They were seen as quiet, efficient, and maybe a little boring. Now, the U9X proves that idea wrong.

With nearly 3,000 horsepower and unmatched acceleration, EVs are not just catching up, they’re overtaking gas cars. Each year, new advancements are breaking barriers that people thought were impossible.

The YangWang U9X is just one example of how quickly the technology moves. It makes you wonder how soon we’ll see EVs dominate every performance record. The electric revolution is speeding up.

Looking ahead to the future

The U9X isn’t just about today’s headlines; it’s a glimpse into the future of cars. It combines cutting-edge batteries, wild suspension tech, and race-level handling into one package.

If BYD can achieve all this in 2025, imagine what 2030 might bring. We could see cars easily breaking 500 km/h, charging faster than filling a gas tank, and handling like nothing we’ve ever known.

The U9X proves that the next era of driving won’t just be electric, it’ll be faster, smarter, and more thrilling than anyone thought possible just a few years ago.

The chase for 500 km/h

The YangWang U9X came close to reaching 500 km/h but fell just short. That number has become the next big milestone in automotive performance, and fans everywhere are asking the same question: who will be first?

BYD has already hinted that another attempt could be made. If the U9X achieves it with an official two-way run, it could rewrite the record books forever. For now, it’s enough to know that a Chinese EV is already faster than Bugatti. The race isn’t over, but BYD has shown it’s ready to lead the charge.
