BYD launched its Seal 08 flagship sedan under the Ocean Network series. The mid-to-large luxury model has dual powertrains, including a pure electric and a plug-in hybrid. Retail pricing begins at 196,900 yuan (28,980 USD) for entry configurations.
This flagship architecture features standard rear-wheel steering and an automated air suspension system. BYD claims the chassis handles tight cornering demands while balancing ride comfort over varied surfaces.

Chassis and scale
The Seal 08 has an exterior footprint measuring 5,150 mm in length and 1,999 mm in width. Height scales to 1,505 mm while the total wheelbase stretches to 3,030 mm between the axles. BYD says these dimensions translate into optimised legroom across the rear seating row.
Integrating a standard rear-wheel-steering setup enables the sedan to achieve a turning radius of 4.95 meters. The chassis relies on the DiSus-A closed dual-chamber air suspension system paired with road preview sensors. Damping adjustments adapt to incoming asphalt patterns before tyres cross surface imperfections.
Battery and power
Pure electric models are built on an 800V high-voltage platform that supports BYD’s flash charging. These electric variations utilise the second-generation BYD Blade battery production framework to deliver a maximum power output of 510 kW. The top electric tier achieves a 905 km CLTC range alongside a 3.3-second sprint to 100 km/h.
Plug-in hybrid configurations combine a 1.5T internal combustion engine with dual electric motors for 400 kW. This hybrid powertrain incorporates a 45.36 kWh battery pack, providing a 400 km pure-electric range. The combined operational range limit is 1,660 km CLTC under standard test conditions.
Cabin and delivery
The interior configuration features dual zero-gravity front seats, along with ventilation and massage for all occupants. Drivers interface with a 15.6-inch touchscreen, a 12.3-inch instrument panel, and a 26-inch augmented reality display. Automated navigation assistance features a lidar sensor to support auto-parking.
