BYD showed up at the 2025 Guangzhou Auto Show with a clear intention: steal the spotlight. And with the debut of the YANGWANG U9 Xtreme, the company may have done exactly that. The limited-run electric hypercar is now officially the fastest production car on the planet.
The big number making headlines is its 496.22 km/h (308 mph) top speed, delivered by a four-motor setup pushing close to 3,000 hp. That’s enough to leapfrog the Bugatti Chiron and give BYD bragging rights few expected from a EV. The company also claimed a 6:59.157 Nürburgring lap time—another eyebrow-raiser for a brand better known for mass-market cars than track weapons.
Only 30 units of the YANGWANG U9 Xtreme are being built, which practically guarantees collector status before the first customer even sits inside. It also slots BYD into a rare corner of the industry where extreme performance isn’t just a feature—it’s the entire mission.
Inside the car is a fully reworked version of BYD’s e⁴ AWD system, upgraded DiSus-X body control, custom aero, and a shell covered in carbon fiber. The oversized wings, vented hood, and huge rear diffuser aren’t just for show—they help keep the car steady as it pushes toward 500 km/h.
Braking comes from titanium alloy calipers paired with a custom carbon-ceramic kit, while the semi-slick GitiSport e·GTR2 PRO tires are rated for a ridiculous 500 km/h, which tells you everything about the performance envelope BYD is aiming for.
At the heart of it all is the new 30C Blade Battery, designed specifically for extreme discharge loads. It uses a dual-layer cooling system and low-resistance cells that can dump massive power in an instant—exactly what you need when each wheel has its own motor.
Pricing is expected to land well below the million-dollar crowd. And judging by the reaction in Guangzhou, BYD has just planted a very loud flag in the hypercar world—one that’s hard to ignore.
