More details have been released about the second generation of the BYD Dolphin Mini, known as Seagull in China, shortly before its official launch. This new model will be larger and feature a rear engine, with its debut in Brazil scheduled for late 2027.
The compact car has received significant mechanical improvements. The electric motor, manufactured by BYD itself, will be moved to the rear axle, providing the vehicle with rear-wheel drive. The TZ164XYB powertrain will have 129 hp, a considerable increase from the 75 hp of the current model. Furthermore, the top speed has been raised from 130 km/h to 150 km/h.
The shift to the rear engine will allow for the inclusion of a front trunk. Another important change concerns the rear suspension, which will transition from a torsion beam to an independent multi-link architecture. The wheels will now be 16 inches, equipped with 205/60 tires.
The battery, made of lithium iron phosphate (LFP) and supplied by FinDreams, BYD's battery division, will offer two configurations: 30 kWh and 39.2 kWh. These options provide ranges of 320 km and 420 km, respectively, according to the Chinese CLTC cycle. These specifications are registered with the MIIT, although final confirmation from BYD is pending at the time of launch.
According to MIIT data, the dimensions of the new Dolphin Mini will be 4.21 m in length, compared to the current 3.78 m; 1.81 m in width and a wheelbase of 2.65 m, up from the previous 2.50 m. In China, the vehicle will accommodate five passengers instead of four. These new measurements bring the model closer to the Geely EX2, which has a length of 4.14 m and the same wheelbase.
Its competitor, marketed in China as Xingyuan, is currently cited as the best-selling car in the country. In August, it recorded 39,651 units sold in the Chinese market, almost four times the volume of the Seagull's 10,103 units, according to compilations from the CarNewsChina website.
Internally, the main innovation is the elimination of the traditional instrument cluster. The speedometer, odometer, and range information will be displayed on the multimedia center, which will be larger, fixed, and located at the top of the dashboard. The gear selector will be relocated to the steering column, and physical controls have been reorganized into a row located under the central air vents.
One of the registered versions includes an optional LiDAR sensor installed on the roof, integrated into the driving assistance system called God’s Eye B. The exterior design has been completely renewed while maintaining the model's identity. The front features a new bumper and redesigned headlights, while the side presents a new C-pillar and a more prominent plastic trim.
In the Brazilian context, the arrival of this new version is scheduled for late 2027. It is important to note that this new generation will not replace the existing Dolphin Mini, which is produced in Camaçari (BA); both models will coexist in the BYD lineup, positioned below the Dolphin GS.
