China’s MIIT type-approval filing for the second-generation BYD Seagull describes a new body on a longer wheelbase, with the motor moved to the rear axle. It is 4,205 mm long, 425 mm more than the first-generation car’s 3,780 mm, and it drives the rear wheels instead of the front.
Second-generation Seagull size and motor
The filing gives a 95 kW (127 hp) motor on the rear axle, and CarNewsChina reports a top speed of 150 km/h. The first-generation Seagull drives its front wheels with a 55 kW motor and tops out at 130 km/h. The wheelbase grows from 2,500 mm to 2,650 mm, and Autohome lists the body at 1,810 mm wide and 1,570 mm tall.
| Seagull (first generation) | Seagull (second generation) | |
|---|---|---|
| Length (mm) | 3,780 | 4,205 |
| Width (mm) | 1,715 | 1,810 |
| Height (mm) | 1,540 | 1,570 |
| Wheelbase (mm) | 2,500 | 2,650 |
| Drive | Front | Rear |
| Motor (kW) | 55 | 95 |
| Top speed (km/h) | 130 | 150 |
The filing also lists five seats and an independent multi-link rear suspension in place of the first generation’s torsion beam. Moving the motor to the rear frees the space under the bonnet, and the car gets a front trunk. CarNewsChina’s follow-up reporting puts it at about 94 litres.

Second-generation Seagull interior and driver assistance
The separate instrument cluster is gone, leaving the central touchscreen as the main display. Around it: a two-spoke steering wheel, physical switches and a wireless phone charger. Higher trims are listed with BYD’s DiPilot 300 driver-assistance package, which adds a roof-mounted lidar.
