BYD Yangwang U9 Xtreme Breaks 500 KPH Speed Barrier
The Chinese electric hypercar sets a new world record reaching 503.17 kph in Abu Dhabi.
1Historic Speed Milestone Achieved
The BYD Yangwang U9 Xtreme has officially become the first production vehicle to exceed 500 kilometers per hour. On November 1, the electric hypercar reached a top speed of 503.17 kph, equivalent to 312.6 mph. This achievement was verified by both the FIA and Guinness World Records in the United Arab Emirates.
2Testing and Technical Adjustments
The record-breaking run occurred on a closed 10-kilometer stretch of the E11 road in Abu Dhabi’s Al Dhafra Region. German driver Marc Basseng required four separate attempts over two days to secure the result. Engineers fine-tuned the vehicle's aerodynamics, suspension settings, and tire pressures between runs to ensure stability at extreme speeds.
3Single Direction Record Methodology
The record was set during a single-direction run, which deviates from the traditional method of averaging two runs in opposite directions. This standard practice usually accounts for wind speed and elevation changes. Consequently, competitors like Rimac, Bugatti, and Koenigsegg may potentially challenge the validity of this specific record-setting methodology in the future.
4Advanced Electric Powertrain Specs
The U9 Xtreme is propelled by four electric motors that produce a combined 2,977 horsepower. The vehicle utilizes a 1,200-volt lithium iron phosphate battery pack capable of discharging at a 30C rate. Stopping power is managed by carbon-ceramic rotors and titanium calipers, while specialized semi-slick GitiSport e-GTR2 Pro tires maintain road contact.
5Limited Production Strategy
BYD intends to manufacture only 30 units of the U9 Xtreme model. As the most powerful and fastest iteration of the U9 supercar line, it serves as a flagship demonstration of the company's high-performance electric vehicle capabilities. This limited production run highlights the brand's focus on exclusive, high-end engineering rather than mass-market output.
6Previous Record Context
This new milestone follows a previous record set by the same vehicle in September 2025, when it reached 496.22 kph. The automaker had explicitly targeted the 500 kph barrier since last year. By consistently pushing these limits, BYD aims to redefine the performance ceiling for electric production vehicles in the global market.
7Regulatory and Industry Recognition
Both the FIA and Guinness World Records have formally acknowledged the U9 Xtreme's performance. The car now holds the official title for the highest speed achieved by a production car and an electric production car in a single-direction run. These certifications provide significant validation for BYD's advanced electric vehicle technology platform.
8Future Implications for EVs
The success of the U9 Xtreme demonstrates that electric powertrains can compete with and surpass traditional internal combustion engines in top-speed metrics. As manufacturers continue to refine battery discharge rates and motor efficiency, the gap between hypercar performance and electric vehicle technology is narrowing, signaling a shift in automotive engineering priorities.
