BYD Seal specs: what actually differs between versions

The BYD Seal in this catalogue is a sedan sold from 1 August 2022. The file lists two generation keys; both are the same first generation: production from 1 August 2022 to 31 January 2026, and a restyling from 1 September 2024 with no stop date. Body type is Sedan on every row. Every version is named AT, fuel Electro, gearbox Automatic with 1 speed. Drive is either RWD or AWD.

The BYD Seal in this catalogue is a sedan sold from 1 August 2022. The file lists two generation keys; both are the same first generation: production from 1 August 2022 to 31 January 2026, and a restyling from 1 September 2024 with no stop date. Body type is Sedan on every row. Every version is named AT, fuel Electro, gearbox Automatic with 1 speed. Drive is either RWD or AWD. CO₂ is 0 on the four first-run versions and not measured on the three restyling versions.

That is the whole choice set: seven AT rows, two drive layouts, two calendar windows, and a handful of measured 0–100, top speed, torque and mass figures.

Generations: first run versus restyling (same generation)

1 generation (1 August 2022 – 31 January 2026), four AT versions. Body: Sedan. Powers: 204 hp (226 kW) RWD; 313 hp (230 kW) AWD; 313 hp (230 kW) RWD; 530 hp (389 kW) AWD. Only the 530 hp AT lists torque: 360 Nm. Only two list mass: 313 hp RWD 2015 / 2390 kg; 530 hp AWD 2150 / 2525 kg. 0–100 km/h: 3.8 s on the 204 hp RWD and on the 530 hp AWD; 5.9 s on the 313 hp RWD; not measured on the 313 hp AWD. Top speed: 240 km/h on the 204 hp RWD; 180 km/h on the 313 hp RWD and on the 530 hp AWD; not measured on the 313 hp AWD.

1 generation, restyling (from 1 September 2024, stop not measured), three AT versions. Same Sedan body, same Automatic 1-speed Electro AT name. Powers move to 228 hp (167 kW) RWD, 308 hp (226 kW) RWD and 523 hp (384 kW) AWD. Versus the first run that is +24 hp on the weaker RWD (228 − 204), −5 hp on the mid RWD if compared with 313 hp (308 − 313), and −7 hp on the AWD flagship (523 − 530). Kilowatts: 167 versus 226 on the two restyling RWD cars (59 kW gap); 384 kW on the restyling AWD, 5 kW below the first-run 389 kW. All three restyling AT versions share the same measured 0–100 km/h of 3.8 s and the same top speed of 240 km/h. Torque, kerb weight, gross weight and CO₂ are not measured on the restyling.

What the restyling changed in this file is therefore not body type or gearbox: it is the three power figures, the uniform 3.8 s / 240 km/h pair, and the absence of mass and CO₂ numbers that the first run partly had.

Engine specs: every AT version

There is no engine size, cc, cylinder count, cylinder layout or boost in the data. Those columns are not measured. Power and, where present, torque are the engine specs that exist.

Horsepower and torque in one place: the only torque figure is 360 Nm on the first-generation AT 530 hp AWD. Power per litre cannot be calculated: displacement is not measured on any AT.

The two AT 313 hp rows are not the same car: one is AWD at 313 hp / 230 kW, the other is RWD at the same 313 hp / 230 kW. The first-generation AT 204 hp lists 226 kW, which is 4 kW below the 230 kW of the 313 hp cars despite 109 hp less on the horsepower column (313 − 204). The restyling AT 308 hp lists the same 226 kW as that 204 hp row, with 104 hp more (308 − 204). Those are the numbers as given; they are not reconciled here with an outside conversion.

Front suspension Independent, spring and rear Independent, spring on every AT. Front brakes Ventilated disc, rear Disc, on every AT.

Performance, top speed, mpg

0–100 km/h

The 313 hp RWD is 2.1 s slower to 100 km/h than the five versions at 3.8 s (5.9 − 3.8). It is also 109 hp above the 204 hp RWD that records the same 3.8 s as the 530 hp AWD. Extra horsepower on the 313 hp RWD does not buy a quicker measured sprint in this file.

Top speed

240 − 180 = 60 km/h. The first-generation 530 hp AWD matches the slower 180 km/h cap of the 313 hp RWD, not the 240 km/h of the 204 hp RWD. After restyling, the 523 hp AWD is listed at 240 km/h, 60 km/h above the first-run 530 hp AWD.

Fuel consumption / mpg: city, highway and combined are not measured on every AT. Tank capacity is not measured. There is no mpg figure to compare. CO₂ is 0 on all four first-generation AT versions and not measured on the three restyling AT versions.

Dimensions and weight

Exterior dimensions in mm, cm or feet are not measured. Ground clearance is not measured. Wheel sizes are not measured.

Measured mass, first generation only:

All other ATnot measurednot measurednot measurednot measured

The 530 hp AWD is 135 kg heavier at kerb (2150 − 2015) and 135 kg heavier at gross (2525 − 2390). Payload is the same 375 kg on both measured cars. Mass per horsepower is 2.38 kg/hp lower on the 530 hp AWD (6.44 − 4.06). Horsepower per tonne of kerb weight: 313 / 2.015 ≈ 155 hp/t on the 313 hp RWD; 530 / 2.150 ≈ 247 hp/t on the 530 hp AWD — 92 hp/t more.

Restyling kerb, gross, tank and clearance: not measured. A weight comparison across the 2024 restyling cannot be done from this file.

Which version to choose

If the buying question is “lowest measured mass per horsepower”: the first-generation AT 530 hp AWD. It is the only version with both 530 hp and 2150 kg kerb. Versus the only other weighed car, the AT 313 hp RWD, you take 217 hp more (69% more power: 217 / 313) and 135 kg more kerb (about 6.7% more mass: 135 / 2015). Payload does not change (375 kg both). You also get the only listed torque, 360 Nm, and AWD instead of RWD. The trade in the same first-generation sheet is top speed 180 km/h, matching the 313 hp RWD, not the 240 km/h of the 204 hp RWD. 0–100 km/h is 3.8 s, 2.1 s quicker than the 313 hp RWD.

If the buying question is “AWD after the restyling”: the AT 523 hp AWD. Versus the first-generation AT 530 hp AWD it is 7 hp and 5 kW down (530 − 523, 389 − 384) and torque is not measured. Versus the restyling AT 308 hp RWD it is 215 hp more (523 − 308) and AWD instead of RWD, with the same listed 3.8 s and 240 km/h. Versus the restyling AT 228 hp RWD it is 295 hp more (523 − 228). Weight of this 523 hp AT is not measured, so you cannot check whether the 7 hp drop versus 530 hp came with a lighter or heavier car.

If the buying question is “RWD, first generation, and a measured 240 km/h”: the AT 204 hp RWD. It is the weakest first-run horsepower (204), 109 hp below each 313 hp AT and 326 hp below the 530 hp AT (530 − 204). It is also the first-generation RWD that matches the 3.8 s / 240 km/h pair later used on all restyling cars. The AT 313 hp RWD in the same generation has 109 hp more and a slower 5.9 s / 180 km/h pair, plus the only RWD kerb weight (2015 kg). Choosing 313 hp RWD over 204 hp RWD buys more horsepower and a known 2015 kg kerb; it does not buy a quicker 0–100 or a higher top speed in this data.

If the buying question is “RWD after restyling”: AT 228 hp or AT 308 hp. Both are RWD Automatic 1 Electro, both 3.8 s and 240 km/h, both without measured torque or mass. The 308 hp AT is 80 hp and 59 kW above the 228 hp AT (308 − 228, 226 − 167). Compared with first-generation RWD: 228 hp is 24 hp above 204 hp; 308 hp is 5 hp below 313 hp. The restyling mid RWD therefore does not out-power the first-generation 313 hp RWD on the hp column; it does match the 3.8 s / 240 km/h of the 204 hp car rather than the 5.9 s / 180 km/h of the 313 hp RWD.

If the buying question is “AWD at 313 hp”: the first-generation AT 313 hp AWD. Same 313 hp / 230 kW as the 313 hp RWD, different drive. 0–100 km/h, top speed, torque and both masses are not measured on this AWD row. You cannot score it against the 530 hp AWD on sprint, speed or kg/hp from this file. What is measured is drive (AWD), power (313 hp / 230 kW), CO₂ 0, Automatic 1, Electro.

What extra power buys, in arithmetic only

Reliability, problems, price. Not in the data; not stated. Sealion, Seal U, Seal 6 / 08 and regional price lists are other catalogue names; they are not these seven AT rows.

Short buy map. Weighed, highest hp/t: first-generation AT 530 hp AWD. Restyling AWD with 240 km/h listed: AT 523 hp. Restyling RWD with more hp: AT 308 hp over AT 228 hp (+80 hp, same 3.8 s / 240). First-generation RWD with 240 km/h: AT 204 hp. First-generation RWD with known 2015 kg kerb: AT 313 hp RWD. First-generation AWD without sprint, speed or mass: AT 313 hp AWD. Displacement, mpg, tank, wheels, ground clearance and restyling weights stay not measured on every version that lacks them.
