A camouflaged prototype of a new electric executive sedan being developed by Yangwang, the most luxurious brand within the BYD Group, has appeared in China ahead of its expected official unveiling in October 2026. The observed design indicates a vehicle targeting the ultra-luxury segment, with a long wheelbase and rear doors that open opposite to the direction of travel. This is the first time such doors have appeared on one of BYD’s vehicles.
The vehicle is approximately 5.5 meters long, placing it in the size range of the Mercedes-Benz Maybach S-Class and Rolls-Royce Phantom. According to the published images, the vehicle was present at one of BYD’s Flash Charging stations, indicating that it will support megawatt-level fast charging, although the company has not announced the final specifications.
Performance Platform and Anticipated Technologies
Local reports expect the sedan to use the four-motor e4 platform, an architecture that could give it more than 1,000 horsepower. Yangwang uses the brand to showcase BYD’s new technologies; the e4 platform, the second generation of Blade batteries, and the Flash Charging system capable of charging in five minutes have previously appeared in its vehicles.
Hu Xiaoqing, Yangwang’s general manager, said that the vehicle represents the result of three years of development, while Zheng Yu, the brand’s managing director, described the technology used in it as “unprecedented and disruptive” without providing details. Therefore, the final capabilities and powertrain specifications cannot yet be considered confirmed.
Will Solid-State Batteries Be Part of the Vehicle?
Local reports indicate that the sedan could be the first BYD vehicle to use solid-state batteries. However, this has not been officially confirmed. Stella Li, BYD’s executive vice president, said in an interview with Carwow.es in September 2026 that the company’s first vehicle equipped with these batteries would appear in 2027.
BYD subsidiary FinDreams is targeting the start of small-scale production of sulfide-based solid-state batteries in 2027, before expanding toward mass production around 2030. If the technology is used in the Yangwang vehicle, it will likely—according to the report—be limited to the highest-priced versions, while standard versions may use Blade batteries with LFP technology. This scenario remains unconfirmed until BYD announces the details.
Why Does This Appearance Matter?
The vehicle reveals BYD’s direction toward competing with ultra-luxury executive sedans not only through price and design, but also by combining high-performance electric propulsion, ultra-high-power charging, and possibly solid-state batteries. However, the significance of the development will be determined once the actual availability of these technologies, the vehicle’s price, and whether it will be offered exclusively in limited versions are disclosed.
The price is expected to exceed two million yuan, or approximately $300,000. For comparison, the current Yangwang U7 sedan starts at 658,000 yuan, while the brand’s lineup also includes the U8 and plug-in hybrid U8L, as well as the high-performance electric U9.
