308 MPH and Counting: Yangwang's U9 Xtreme Claims the Fastest Production Car Title
Last month, BYD's luxury brand Yangwang toppled Rimac Nevera with the U9 Track/Special Edition, reaching 293.54 mph. Yet that crown wasn't enough. The U9 Xtreme now hits 308.34 mph—nearly 15 mph faster and 3.557 mph quicker than the Bugatti Chiron Super Sport 300+.

From Track to Xtreme: The U9 Xtreme Is the Production Version
Yangwang says the U9 Xtreme, or U9X for short, is the full production version of the Track/Special Edition that claimed the crown in August. Its electronics have been updated since that 294 mph run, and the company now claims 'Over 3,000' horsepower from the car's four 30,000 rpm electric motors.
The Power Figure: "Over 3,000" Horsepower From Four 30,000 RPM Motors
That 'Over 3,000' horsepower number comes from four electric motors spinning at 30,000 rpm. It's a jaw‑dropping figure in an era of escalating horsepower, underscoring how the speed war has shifted to electric propulsion.
Production, Certification and the Direction Debate
Yangwang will produce 30 examples of the U9 Xtreme. Its top speed was certified by the Automotive Testing Papenburg facility, which would normally qualify it as the world's fastest production car. However, some speed lists exclude the U9X because the run reportedly occurred in a single direction, not the standard two-direction average.
Two Runs or One? The Record Debate in the Speed Era
To be universally accepted, many lists require two runs. Even without universal agreement, the U9 Xtreme marks a historic leap and signals a broader shift in automotive performance. Whether two runs are recorded, the car confirms a new era of EV speed.
