Chinese type-approval filings have revealed BYD's next-generation Seal, which now runs on second-generation Blade LFP batteries. In its strongest configuration the sedan is certified at 718 km on the WLTP cycle and 875 km on China's more generous CLTC test, and this marks the first time the Blade 2.0 cells appear in one of the company's high-volume models.
Chinese buyers will get two pack options. The entry rear-drive version pairs a 76.7 kWh battery (539 kg, roughly 28% of the car's mass) with a 333 hp rear motor for up to 775 km CLTC, or 636 km WLTP. The larger 88.7 kWh unit feeds a 408 hp motor and unlocks a 240 km/h top speed. The standout feature of the new chemistry is its charging pace: the pack can go from 10 to 97 percent in nine minutes.
Plug-in hybrid variants stay on offer with DM-i hardware — a 156 hp 1.5 turbo engine working alongside a 218 hp electric motor, a 38 kWh battery covering 245 km on electricity alone, and consumption of 4.25 l/100 km once the charge runs out.
The car itself has grown: 5.08 m long versus the old 4.80 m, 1.96 m wide versus 1.87 m, 1.50 m tall, with the 2.96 m wheelbase carried over. The rapid update, arriving barely five months after the previous line reached Chinese showrooms, appears to be a response to weak demand — BYD moved only 1,005 Seal 07 units there in August 2026, and the new version will sit below the Seal 08 in the D segment.
