BYD electric car reaches 496 km/h and sets new speed benchmark for production vehicles

The electric super sports car Yangwang U9 Xtreme, developed by Chinese manufacturer BYD, redefined performance parameters in the automotive sector by setting a new world speed record. The vehicle reached the mark of 496.22 km/h, consolidating itself as the fastest production car on the planet. The historic feat was achieved on the ATP Automotive Testing Papenburg test track, on Alemanha, and validated under strict inspection conditions.

Driving the vehicle was the responsibility of the experienced German driver Marc Basseng, known for his victories in long-term races, such as the 24 Horas at Nürburgring. The record, set on September 14, 2025, not only surpassed the previous mark of 490.48 km/h, held by the Bugatti Chiron Super Sport 300+, but also demonstrated the overwhelming potential of electric propulsion technology in extremely high-performance applications.

The impact of the achievement was quickly recognized by the industry, culminating in the event being chosen as the “Ano Moment” in the prestigious TopGear.com 2026 awards. The award, announced last Friday, celebrates not only pure speed, but also the relevance of progress towards the energy transition and the consolidation of BYD as an innovative force in the supercar segment.

Technological advances behind speed

The extraordinary performance of the Yangwang U9 Xtreme is a direct result of a set of technological innovations developed by BYD. The heart of the system is an electrical platform that operates at 1,200 volts, a significant jump from the base model’s 800 volts, enabling faster, more efficient energy discharges crucial to achieving peak power and speed. The super sports car is driven by four independent electric motors, one for each wheel, which together deliver a combined power of over 3,000 horsepower and reach a maximum speed of 30,000 rpm. Essa configuration results in a power-to-weight ratio of 1,217 hp per ton, another global record for production electric vehicles. Power is provided by the advanced Blade battery, composed of lithium iron phosphate (LFP), designed to withstand discharges of up to 30C, which minimizes overheating during extreme accelerations and ensures system stability. The DiSus-X suspension, an intelligent and adaptive system, was recalibrated specifically for the record, controlling lateral and vertical forces at speeds above 400 km/h and keeping the car stable and safe.

The track record of Papenburg

The choice of the high-speed oval track at Papenburg, in the north of Alemanha, was strategic for the record attempt. Suas long straights and wide-radius curves offer ideal conditions for high-performance vehicles to reach their maximum speed safely. The test was conducted under a strict protocol to guarantee official approval, with measurements carried out by equipment certified by Federação Internacional of Automobilismo (FIA).

During the attempt, pilot Marc Basseng accelerated the U9 Xtreme progressively, reporting a notable lack of instability even when surpassing the 450 km/h barrier. Segundo Basseng, acceleration was stopped close to 496 km/h as a precautionary measure, although the vehicle still demonstrated the potential to go further. During the test, the car was equipped with special 20-inch wheels and semi-slick tires, developed to withstand the extreme forces generated at very high speeds.

Test preparation and strategy

The success on the German track was the culmination of months of intensive preparation by the BYD engineering team. The development of the U9 Xtreme involved extensive computer simulations to predict and optimize the vehicle’s aerodynamic behavior at extreme speeds, resulting in a drag coefficient of just 0.28.

Practical validations were carried out on several circuits at China, where the stability of the engines and the efficiency of the cooling system were put to the test. The team focused efforts on reducing chassis weight without compromising torsional rigidity, an essential factor for safety and drivability.

Pilot Marc Basseng underwent specific training in advanced simulators to adapt to the instantaneous and linear torque delivery of electric motors, a characteristic that differs drastically from the power curve of combustion engines. The validation process also included more than 500 hours of dynamometer testing to ensure the durability of all components under maximum stress.

Performance at the Nürburgring and other circuits

Before breaking the top speed record, the Yangwang U9 Xtreme had already demonstrated its superiority on one of the most challenging circuits in the world: the Nürburgring Nordschleife, also on the Alemanha. In August 2025, the model completed a lap of the 20.8 km track in 6 minutes and 59.157 seconds, becoming the first production electric car to record a time below the seven-minute mark.

This feat surpassed the previous record, which belonged to Xiaomi SU7 Ultra, with a time of 7 minutes and 4.957 seconds. The exceptional performance at the Nürburgring is a testament to the effectiveness of the all-wheel drive system, which allows extremely fast corner exits, and the efficiency of the regenerative and hydraulic braking systems.

The ability to dissipate heat efficiently was crucial during the 73 test laps carried out on the circuit, known for its variations in terrain and high, medium and low speed curves. The mechanical assembly has proven its robustness and reliability under extreme conditions.

In addition to its performance on the track, the U9 Xtreme presents impressive acceleration figures, reaching 100 km/h in just 2.36 seconds. The autonomy, certified at 450 km in the Chinese CLTC cycle, ensures that the vehicle can withstand prolonged sessions of intense use without the need for constant recharging.

Repercussions on the automotive industry

Stella Li, executive vice president of BYD, stated in an official statement that the record is the result of years of research and dedication by the company’s vast engineering team. Ela highlighted that the feat represents a milestone not only for the brand, but for the entire electrified vehicle industry, proving that sustainability can coexist with extreme performance.

Jack Rix, editor-in-chief of TopGear.com, justified the election of the record as “Ano Moment” by highlighting that the U9 Ele commented that BYD is effectively challenging the historical dominance of European brands in the high-performance segment.

Comparison with previous milestones

The new mark of 496.22 km/h places the Yangwang U9 Xtreme at the absolute top of the speed hierarchy, surpassing icons of automotive engineering. The previous record for production cars, set in 2019 by the Bugatti Chiron Super Sport 300+, was 490.48 km/h. BYD’s achievement is significant as it is the first time that a fully electric vehicle has taken this position. Entre for trams, the record belonged to the Rimac Nevera, with 431.45 km/h, a mark that was surpassed by the U9 Xtreme by more than 15%, demonstrating a substantial technological leap.

Production, price and future availability

BYD, through its luxury sub-brand Yangwang, plans a highly exclusive production run for the U9 Xtreme, with just 30 units expected to be manufactured. The model will be aimed at collectors and high-performance enthusiasts, with an estimated price of 1.68 million yuan, which is equivalent to approximately R$1.3 million in direct conversion.

The company also confirmed its global expansion plans. The launch of the U9 Xtreme at Europa is scheduled for early 2027, along with the U8 luxury SUV. Para support demand, BYD is investing in expanding its manufacturing operations on the continent, including a new plant in Alemanha.
