BYD Second-Generation Seal 07 Launches November 5, Growing to 5,080 mm

BYD will launch the second-generation Seal 07 sedan on November 5, 2026, refreshing its Ocean lineup with a larger sedan offering battery-electric and plug-in-hybrid options, according to CnEVPost reporting on November 1. The new model grows to 5,080 mm in length and adopts the Ocean Aesthetics 2.0 design language, with styling aligned with the Seal 08. First display cars have already arrived at dealerships in 131 Chinese cities, and the battery-electric version opened for reservations on October 26 — without pricing being announced.

The hardware updates are substantial. The battery-electric version will feature the second-generation Blade Battery and flash charging technology, plus the DiSus-M intelligent magnetorheological body control system. Regulatory filings show two electric motor options with peak outputs of 245 kW (329 hp) and 300 kW. The plug-in-hybrid version retains the Seal 07 DM-i name, pairing a 1.5-liter turbocharged engine with a 160 kW drive motor and a 38.029-kWh battery pack for a WLTC electric range of 245 kilometers (152 miles).

The refresh comes as the Seal lineup faces sales pressure: cumulative sales fell 14.11 percent year over year in the first nine months, and the lineup sold 46,718 vehicles in September, down 9.04 percent year over year. A bigger, better-equipped sedan without a price yet is a deliberate teaser strategy — it builds showroom traffic before the number that decides the deal is revealed. November 5 will show whether BYD prices the new Seal 07 to defend volume or to defend margin.
