BYD Seagull: Which Version Should You Buy?
The choice between the BYD Seagull AT 30 kWh and AT 38 kWh comes down to battery designation rather than performance. Both versions have an electric powertrain producing 75 hp (55 kW), a 1-speed Automatic gearbox, FWD, and a top speed of 130 km/h.
The choice between the BYD Seagull AT 30 kWh and AT 38 kWh comes down to battery designation rather than performance. Both versions have an electric powertrain producing 75 hp (55 kW), a 1-speed Automatic gearbox, FWD, and a top speed of 130 km/h. The available data does not provide range, charging figures, prices, acceleration, dimensions, or weights, so it cannot establish whether the AT 38 kWh delivers enough additional real-world capability to justify any price difference. Based strictly on the documented specifications, the AT 30 kWh is the simpler default choice, while the AT 38 kWh is worth considering only after confirming its range, charging characteristics, and price from another source.
BYD Seagull generations and version choice
The BYD Seagull has 1 generation, in production since April 2023. This generation uses a Mini 5-doors body and includes 2 modifications: AT 30 kWh and AT 38 kWh.
There is no intergenerational choice to make because the catalogue records only this generation. It also contains no restyling information, so no claim can be made about changes introduced by an update. For buyers comparing model years, including cars advertised as a later model year, the supplied specifications establish only that production began in April 2023 and has no recorded stop date.
BYD Seagull specs comparison
| Version | Power | Torque | Displacement | Fuel | Cylinders | Cylinder layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| AT 30 kWh | 75 hp (55 kW) | not measured | not measured | Electro | not measured | not measured | not measured | 1-speed Automatic | FWD |
| AT 38 kWh | 75 hp (55 kW) | not measured | not measured | Electro | not measured | not measured | not measured | 1-speed Automatic | FWD |
The power difference between the two versions is 0 hp and 0 kW. Both therefore have the same catalogue engine power, gearbox type, number of gears, and driven axle.
Power per litre cannot be calculated because displacement is not measured. Weight per horsepower also cannot be calculated because kerb weight is not measured. Torque output and horsepower-to-torque comparisons are unavailable because torque is not measured for either version.
BYD Seagull engine and drivetrain
The AT 30 kWh uses an Electro powertrain rated at 75 hp (55 kW). It has a 1-speed Automatic gearbox and FWD. Torque, displacement, cylinder count, cylinder layout, boost, and engine location are not measured.
The AT 38 kWh also uses an Electro powertrain producing 75 hp (55 kW). It likewise combines a 1-speed Automatic gearbox with FWD. Torque, displacement, cylinder count, cylinder layout, boost, and engine location are not measured.
Consequently, searches for BYD Seagull engine capacity, engine displacement, engine size, or engine cc do not have a numerical answer in this dataset. The relevant comparison is electric output: both versions provide exactly 75 hp (55 kW).
BYD Seagull performance, range, and economy
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| AT 30 kWh | not measured | 130 km/h | not measured | not measured | not measured | 0 |
| AT 38 kWh | not measured | 130 km/h | not measured | not measured | not measured | 0 |
Neither version has a measured 0–100 km/h figure in the supplied data. Both have the same listed maximum speed of 130 km/h, making the top-speed difference 0 km/h.
Range is not measured for either the AT 30 kWh or AT 38 kWh. Energy consumption is also not measured, so the data cannot support an mpg-equivalent or efficiency comparison. Although the version names contain 30 kWh and 38 kWh, the catalogue provides no measured range or consumption result connecting those designations to driving distance.
The listed CO₂ figure is 0 for each version, a difference of 0. No fuel-tank capacity is measured.
BYD Seagull suspension and brakes
Both versions have Independent, spring front suspension and Independent, spring rear suspension. Their braking specifications are also identical: Ventilated disc brakes at the front and Disc brakes at the rear.
This means the available chassis data reveals no equipment difference between the AT 30 kWh and AT 38 kWh. Any claim that one rides, handles, or stops better would go beyond the supplied facts.
BYD Seagull dimensions and weight
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| AT 30 kWh | not measured | not measured | not measured | not measured | not measured |
| AT 38 kWh | not measured | not measured | not measured | not measured | not measured |
Exterior dimensions are not measured in the provided data, so length, width, height, and their conversions into millimetres, centimetres, metres, inches, or feet cannot be stated. Ground clearance and wheel sizes are also not measured.
Kerb and gross weights are not measured for either version. It is therefore impossible to determine whether the battery designation is associated with extra mass or to calculate payload, power-to-weight ratio, or weight per horsepower.
BYD Seagull price: what does paying more buy?
Prices are not provided, so no purchase-price comparison is possible. The data also does not establish that the AT 38 kWh necessarily costs more in any particular country or market.
On paper, moving from the AT 30 kWh designation to AT 38 kWh adds 8 kWh to the number shown in the version name, an increase of approximately 26.7% relative to 30 kWh. However, the supplied data does not provide measured battery capacity as a separate specification, nor does it provide range, charging time, charging power, weight, or efficiency. The 8 kWh nameplate difference therefore cannot be translated into a supported range gain or monetary value here.
There are no supplied prices for the USA, Canada, the Philippines, Mexico, Egypt, or any other market. Availability in those markets is also not recorded.
Reliability and problems
Reliability results and reported problems are not included in the data. The specifications show that both versions share the same 75 hp (55 kW) output, 1-speed Automatic gearbox, FWD, suspension descriptions, brake types, and 130 km/h top speed, but shared catalogue specifications do not prove identical long-term reliability.
Service intervals, warranty terms, battery degradation, repair costs, safety records, and owner-reported faults are not measured. None of these should be used to choose between the versions without separate evidence.
Which BYD Seagull version should you choose?
Choose the AT 30 kWh if you want the default option supported by the available comparison. It matches the AT 38 kWh in every documented performance and chassis figure: 75 hp (55 kW), 130 km/h, 1-speed Automatic, FWD, Independent, spring suspension at both ends, Ventilated disc front brakes, and Disc rear brakes.
Choose the AT 38 kWh only if verified market-specific information shows a useful advantage in range, charging, equipment, or price. None of those advantages is measured in the supplied catalogue data. Its version name is numerically 8 kWh above AT 30 kWh, but power increases by 0 hp, output increases by 0 kW, and top speed increases by 0 km/h.
The decisive missing figures are price and range. If those remain unavailable, the AT 30 kWh is the more conservative selection because the documented data identifies no performance benefit for the AT 38 kWh. If independent figures confirm that the AT 38 kWh offers additional usable range at an acceptable premium, it becomes the logical choice for buyers who value greater driving distance.
