World's Fastest Car: The Yangwang U9 Xtreme

The fastest production car in the world is an electric hypercar producing nearly 3,000 horsepower from four electric motors. The Yangwang U9 Xtreme is an impressive vehicle that is capable achieving a top speed of 496.22 km/h (308.4 mph), with an acceleration that is relentless, smooth, and brutally fast, says Oliver Taylor.
 

Some of the great Japanese mass-produced automobile manufacturers have a luxury brand division associated with them, whether it be Toyota Motor Corporation’s Lexus, Honda Motor Company’s Acura, or Nissan Motor Company’s Infiniti. Today, China has stepped in to exert their dominance in the automotive industry. BYD Auto now has Yangwang, their flagship luxury NEV (New Energy Vehicle) brand specialising in high-end, technologically advanced electric vehicles. A young brand with just a few years of history The car’s logo represents the Chinese character for ‘lightning’ or ‘electricity’.

According to Yangwang, ’cars that redefine eras are born from a resolute spirit’, and this is certainly evident as the Yangwang U9 Xtreme recently surpassed the Bugatti Chiron Super Sport’s top speed of 304 miles per hour! The YangWang U9 Xtreme was  previously known as the ‘U9 Track Edition’, before being rebranded after shattering new records at the Automotive Testing Papenburg track in Germany.
 

EXTREME POWER

This car may not be well known, but is almost three times more powerful than the Tesla Model S Plaid, and is rooted in BYD’s three decades of pioneering electrification expertise. Yangwang is the first brand to introduce BYD’s proprietary individual wheel drive technology platform named e4 and the car has the ability to sprint from 0-62mph in 2.36 seconds. With design directed by German car design connoisseur Wolfgang Egger, who previously served as a leading designer for European luxury automobile brands like Audi, Alfa Romeo and Lamborghini, the car’s visuals highlight the merger of Chinese cultural inspiration, with futuristic and aerodynamic aesthetics.

Wolfgang Egger was instrumental in shaping the BYD’s brand design identity and designing several models for both BYD and Yangwang. The recent speed benchmark of the U9 Xtreme was achieved by German racing driver Marc Basseng, who described the experience as driving in ‘unchartered territory,’ requiring immense trust in the car’s stability and in reliability of the vehicle’s custom tyres.
 

Officially debuting at the 2025 Guangzhou Auto Show, the engineering of the Yangwang U9 Xtreme features a combined system output of 2,978 bhp, with each electric motor delivering 744 bhp and spinning at up to 30,000 rpm. This is more than double the 1,288 bhp of the standard U9 model, and provides a respectable power-to-weight ratio of 1,217 bhp per tonne. These motors possess the thinnest super-silicon steel in mass production with sheets that are a mere 0.1 mm thick, which is itself a technical breakthrough- designed to minimise energy loss and increase motor efficiency.

An innovative powerhouse, the Yangwang U9 Xtreme is the first production car with a 1,200V ultra high voltage platform capable of supporting the same amount of electricity that is used to power some electric trains. When combined with the optimised thermal management system, this allows the sustained and confident delivery of extreme performance. Multi-loop liquid cooling is allocated for the car’s battery, motors and inverters, allowing for maximum power output without the bottleneck of thermal limitations. Indeed there are very few cars in the world that can outclass this vehicle, thanks to its total of 960 kWh coming from the four motors and a formidable 1,680 Nm of torque.
 

INNOVATION AND PRECISION

The vehicle is housed within a revolutionary 3D-printed aluminium alloy chassis, with metal-additive manufacturing that features a unique lightweight honeycomb design to enhance torsional rigidity and safety. The U9 Xtreme’s 3D-printed high-performance body, combines lightweight construction and structural integration, with game-changing innovation that extends the boundaries of supercar safety. The car weighs 2,480 KG, and has a special DiSus-X Intelligent Body Control System that can individually adjust itself on all four corners. The front hood contains a dual-through design, intended to optimise aerodynamics and cooling, while the vehicle’s aggressive front splitter and large rear wing, generate significant downforce which enables the U9 Xtreme to remain stable at high speeds.

The driver-focused precision cockpit was also built with high-speed stability in mind, comprised of lightweight carbon fibre and Alcantara. Control is prioritised over distraction, with a low, somewhat reclined driver position and high-grip bucket seats designed to maintain driver stability under high G-forces. The interior features a 12.3-inch digital instrument cluster and 15.6-inch vertical screen, automatic climate control, a spacious cabin and a multi-function compact steering wheel, ergonomically created for maximum grip and precision.
 

Underpinning the breathtaking achievements and blistering speeds realised by the Yangwang U9 Xtreme, lies the collaboration which merges BYD’s automotive expertise with the material innovation of Bright Laser Technologies (BLT), to completely reshape the physical limits of an electric hypercar. BLT’s advanced 3D-printing technology enables a weight reduction of 30%, compared with other manufacturing methods. In addition, thanks to the car’s fast-acting hydraulics, the vehicle can even jump to clear potholes and obstacles! Say goodbye to damaged suspension components, bent tyres and cracked wheels. The Yangwang U9 Xtreme achieves this by lowering itself and then instantly extending the hydraulic suspension, launching the car upwards. It is even capable of spinning on the spot, similar to a tank.
 

AN EXCLUSIVE MODEL

The vehicle features 20-inch twin five-spoke wheels with GitiSport e-GTR2 PRO semi-slick tyres, designed for extreme speeds, and the high-performance carbon-ceramic braking system includes level three autonomous driving. According to Yangwang, the U9 Xtreme’s e4 platform enables ‘precise longitudinal and lateral body posture control, ensuring stable power delivery and composure amid the dynamic demands of complex track surfaces.’  The four-wheel distributed drive motors enable precise wheel-end torque vectoring and the system continuously monitors feedback from the road, adjusting the torque delivered to each wheel more than 100 times per second.

The meticulous regulation of axle-load transfer and mass distribution for cornering control, makes the driving experience exceptionally pleasant. A performance-focused tread design, handles increased pressures on the tyres at high speeds, and a specialist knurling with high viscosity lubricant, minimises slippages during hard acceleration. All of these elements are of course, contributory factors to the Yangwang U9 Xtreme’s capacity to shatter world records. The electric super-coupe is also powered by an 80 kWh Lithium Iron Phosphate (LFP) Blade Battery designed by BYD, with a superb 30C discharge rate (approximately ten times more than ordinary electric vehicle) enabling extreme, sustained and stable power delivery while driving.

The Yangwang U9 Xtreme demonstrates the peak of BYD’s automotive capabilities and is the fastest non road-legal automobile in the world. Chinese automakers are making such an impact in the industry that other companies like Volkswagen and Toyota are being forced to rethink their entire strategy for the coming decade. Priced at $252,630, the Yangwang U9 Xtreme is an exclusive luxury supercar model with a production run that is limited to just 30 units worldwide. With limited availability set to make prices for the world’s fastest automobile significantly higher in the not too distant future- be sure to get one while you can.   EG
