The record-breaking run showcases how next-generation platforms, high-voltage architectures, and intelligent body control systems are redefining the limits of performance, stability, and safety in sustainable mobility.
YANGWANG, BYD’s premium sub-brand, has redefined the boundaries of electric performance with its latest achievement: the U9 Track Edition supercar clocked a record-breaking 472.41 km/h at the ATP Automotive Testing track. The feat secures its title as the world’s fastest EV and establishes a new benchmark in sustainable high-performance mobility.
At the core of this accomplishment is YANGWANG’s e⁴ Platform and DiSus-X Intelligent Body Control System, technologies that together provide unparalleled power, precision, and stability. The Track Edition is the first supercar to integrate a mass-produced 1200V ultra-high-voltage vehicle platform, coupled with a next-generation thermal management system optimized for extreme speeds. The key features are:
- Quad high-performance motors: each spins up to 30,000 rpm
- Combined output: over 3,000 PS
- Power-to-weight ratio: 1,217 PS/tonne, matching elite supercars
Drivers experience relentless acceleration and top-tier racing performance without sacrificing control.Stability at high speed comes from the quad-motor torque-vectoring system, adjusting wheel torque over 100 times per second. In tandem, the DiSus-X suspension performs micro-adjustments independently at each corner, suppressing pitch and roll while optimizing tyre grip. Together, these systems guarantee safety, responsiveness, and confidence, even under extreme track conditions.
Aerodynamic enhancements, including an optional carbon-fiber front splitter, ensure the U9 maintains composure at record-setting velocities. Complementing this, a collaboration with Giti Tire has produced bespoke semi-slick tyres with optimized compounds and knurled wheel interfaces, minimizing slippage, reducing torque loss, and extending durability in track scenarios. Behind the wheel, German professional driver Marc Basseng, who also set the previous global EV record in 2024, reflected: “I never expected to break my own record so soon. The U9 Track Edition proves what’s possible when innovation meets engineering precision.”
