The upcoming BYD Seagull utilizes a 95 kW electric motor and FinDreams lithium iron phosphate cells. Credit: MIIT Understand China EV’s Market Real-time notifications when critical EV data is released All important data in one place 2,000,000+ data points Become a member BYD Seagull electric hatchback configurations have officially surfaced in the latest regulatory declaration catalogue from the Chinese government. The Ministry of Industry and Information Technology published the certified vehicle specifications on July 10, 2026. This comprehensive generational update introduces major architectural changes to the popular urban electric platform. The updated vehicle architecture implements an overhauled physical footprint featuring a length of 4205 mm, a width of 1810 mm, and a height of 1570 mm. The wheelbase stretches to 2650 mm, which marks a 150 mm increase over the previous model year database baseline. This larger structural design expands the body length by 425 mm and shifts the vehicle closer to the footprint of its larger sibling platform, the Dolphin. Powertrain and battery The updated hatchback configuration utilises a permanent magnet synchronous motor manufactured by Zhengzhou BYD Auto Co., Ltd. This electric drive unit, designated under model number TZ164XYB, delivers a peak power output of 95 kW (127 hp). This 95 kW output marks a mechanical expansion over the 55 kW (75 hp) motor utilised in the preceding model baseline, adjusting powertrain parameters to match the larger vehicle dimensions. Certified regulatory data confirms the propulsion system achieves a maximum top speed of 150 km/h. Energy storage relies entirely on lithium iron phosphate cells supplied by Shaoxing FinDreams Battery Co., Ltd. The component manufacturer also handles the final assembly of the complete functional battery pack. This hardware update builds directly on prior iterations, such as the 2026 BYD Seagull launch, which sustained the brand’s low-voltage product offensive. Mass and options The vehicle mass parameters reflect the increased physical dimensions of the chassis structure. The primary regulatory documentation notes a baseline curb weight variation of 1,180 kg, with a maximum total weight of 1,555 kg. Alternative high-specification lines record an expanded curb weight of 1,255 kg and a gross vehicle mass of 1630 kg. The manufacturer offers extensive exterior customisation options to support diverse consumer preferences. These accessories include distinct aerodynamic wheel designs, fender embellishments, side skirt trim strips, and various regional model badges. The five-seat cabin layout is supported by standard 205/60 R16 specification tyres across all catalogued variants. Market and nomenclature The passenger car operates under several regional naming schemes globally to manage international retail distribution. The automaker utilises the BYD Atto 1 and BYD Dolphin Surf designations depending on the specific destination market. Furthermore, the company deploys the BYD Dolphin Mini moniker alongside its core BYD Seagull identity under the overarching BYD corporate ecosystem. Smart driving capabilities receive a hardware expansion through an optional camera setup integrated into the high-mounted brake light assembly, following earlier observations of a lidar-equipped hatchback variant undergoing road testing. Competitive market vectors show Geely EX2 (Xingyuan) domestic sales reached 33,359 deliveries in June 2026, capturing a substantial brand share, according to China EV DataTracker. By comparison, the BYD Seagull recorded 9,825 retail sales during the same period, underscoring the strategic urgency of this dimensional expansion.
