On 22 September 2026, BYD released official design sketches of the second-generation Seagull, which will go on sale in China under the name Great Seagull (Da Haiou). The drawings were published by Zhang Zhuo, the executive overseeing sales for BYD's Ocean-series dealer network, and preview a noticeably sportier city hatchback: large trident-shaped headlights, crisply creased bodywork, widened wheel arches, a lower windshield line and 16-inch eight-spoke alloys.
The new model is far bigger than the car it replaces. At 4,205 mm long, 1,810 mm wide and 1,570 mm tall on a 2,650 mm wheelbase, it adds 425 mm of length over the current Seagull and comes within 65 mm of the larger Dolphin. BYD says the cabin has been completely repackaged to free up more space; earlier spy shots have shown a floating touchscreen, a gear selector mounted behind the steering wheel and a substantial center console.
Chinese type-approval filings suggest a single electric motor with 130 PS and a 150 km/h top speed, paired with a choice of 30 kWh or 39.2 kWh LFP batteries from BYD's FinDreams unit, good for roughly 320-420 km of CLTC range. A roof-mounted LiDAR sensor anchors the DiPilot 300 suite — marketed as “God's Eye B” — enabling Navigate-on-Autopilot assisted driving on city streets and highways alike.
The overhaul arrives as the outgoing Seagull loses steam: Chinese deliveries fell 66.5% year on year to 74,087 units between January and August 2026 amid fierce competition in the mini-EV segment, while the current car's small footprint limits its usefulness as a household's only vehicle. Priced today at 69,900-85,900 yuan, the model is counting on its larger successor to reignite BYD's entry-level city-car business.
