BYD is preparing a new battery-electric (BEV) version of its Yangwang U7 flagship sedan, and the biggest change is the introduction of larger and alternative battery pack options. According to the latest information, the upcoming Yangwang U7 BEV variant will be offered with two Blade battery (LFP) capacities: a 150.01 kWh pack and a 135.5 kWh pack. With these batteries, the car is expected to deliver multiple CLTC driving-range figures depending on configuration. The 150.01 kWh option is quoted with CLTC ranges of 1,006 km and 860 km, while the 135.5 kWh version is listed with a CLTC range of 800 km in this newly disclosed lineup.
The Yangwang U7 itself first entered the market in March 2025. BYD positions it as a top-tier “new energy” sedan aimed at the ultra-premium end of the segment, often described as a “million-class” flagship in Chinese-market terms. Pricing starts at the equivalent of around US$89,800, and the model is offered with both four-seat and five-seat cabin layouts. Buyers can also choose between pure-electric (BEV) and plug-in hybrid (PHEV) powertrains. A new PHEV variant was previously revealed through China’s Ministry of Industry and Information Technology (MIIT) filings in October, indicating BYD’s plan to broaden the U7 range further.
More recently, in early December, MIIT disclosures provided additional details about the BEV version. Those documents indicate the upcoming BEV continues to be sold in both 4-seat and 5-seat forms, and that these variants share the same overall exterior appearance. Dimensionally, the U7 remains a large sedan, measuring 5265 mm long, 1998 mm wide, and 1517 mm tall, while riding on a 3160 mm wheelbase—figures that align with the existing production model. MIIT data also lists several curb-weight figures across different BEV configurations. The weights shown include 3,120 kg, 3,195 kg, and 3,290 kg for certain versions, along with another listed figure of 3,095 kg, highlighting just how heavy this high-performance, large-battery sedan is expected to be.
On the performance side, the new BEV is widely expected to keep the same basic multi-motor layout. The documents point to a drivetrain using four permanent-magnet synchronous motors, each rated at a maximum of 240 kW, which together bring total system output to about 1,287 hp. For perspective, the currently available BEV version on sale uses the 135.5 kWh Blade battery and is rated at 720 km CLTC range. That model is also credited with a 270 km/h top speed and a 0–100 km/h time of 2.9 seconds, underlining that the U7 is designed to blend long-range capability with supercar-like straight-line performance.
The newly listed 150.01 kWh battery pack is also heavier. MIIT information indicates the 150.01 kWh pack weighs 926 kg, compared with 903 kg for the existing 135.5 kWh pack, reflecting the additional energy capacity and associated mass.
Beyond batteries and power, the Yangwang U7 is known for advanced high-end tech, and the new BEV variant is expected to retain these flagship features. Key equipment includes BYD’s premium “God’s Eye A” advanced driver-assistance system (DiPilot 600), which uses three lidars, as well as the DiSus-Z suspension technology. The car also sits on BYD’s e4 (Yisifang) platform architecture that supports the four-motor setup, and it boasts an exceptionally low 0.195 Cd drag coefficient. All signs suggest the refreshed BEV version will continue with the same core hardware, while expanding buyer choice through new battery-and-range combinations.
