BYD has published official sketches of the second-generation Seagull's cabin, and the biggest change is what's missing: there is no dedicated driver display, with all driving information routed to the floating central touchscreen. The wheel is a new two-spoke unit, the gear selector moves to a column stalk, and a horizontal row of physical buttons sits below the center vents. A raised console bridge carries two cupholders and a wireless charging pad.
Homologation data filed with China's MIIT lists the new hatch at 4,205 mm long with a 2,650 mm wheelbase — gains of 425 mm and 150 mm over the outgoing car — and seating for five instead of four. That makes it longer overall than the Dolphin, though the Dolphin retains a 50 mm longer wheelbase. Chinese media have taken to calling it the "Great Seagull," while the current smaller model is exported as the Atto 1, Dolphin Mini, or Dolphin Surf.
Both filed variants use a 95 kW (127 hp) motor built at BYD's Zhengzhou plant, fed by FinDreams lithium iron phosphate packs of 30 kWh or 39.2 kWh. Those correspond to 320 km and 420 km of CLTC range, roughly 259 km and 340 km on WLTP. One variant can be optioned with a roof-mounted LiDAR linked to the DiPilot 300 (God's Eye B) driver-assistance system.
The Seagull remains a solid seller, with 10,103 units delivered in China in August 2026, but it is dwarfed by the Geely Xingyuan (EX2), which manages 39,651 sales that same month on the identical 2,650 mm wheelbase. Pricing for the new car is unannounced — the current one starts at 69,900 yuan — and BYD has only committed to a launch within this year, without clarifying whether the two will be sold side by side.
