Jaecoo J8

Specs that decide the purchase: 1.5 DHT

That is the entire powertrain menu. If a dealer offers another J8 nameplate, it is outside this catalogue.

1.5 DHT is a Plug-in, Turbo, Inline 4-cylinder, 1499 cm³, Front, transverse, Automatic 3-speed, AWD SUV 5-doors. Output is 597 hp (439 kW); peak rpm for power is not measured. Peak torque is 650 Nm; torque rpm is not measured. Fuel is 95. Compression ratio is 14.5. Bore and stroke are 77.0 x 80.5. Valves per cylinder: 4. Fuel system: not measured.

That is the entire powertrain menu. If a dealer offers another J8 nameplate, it is outside this catalogue.

Engine: power per litre and what 1.5 DHT actually is

Displacement is 1499 cm³, or 1.499 litres. Specific output is 597 ÷ 1.499 ≈ 398.3 hp per litre. Specific torque is 650 ÷ 1.499 ≈ 433.6 Nm per litre. Those ratios are high because the version is Plug-in and Turbo, not because a larger petrol block is listed.

The ICE side is still a 4-cylinder Inline Turbo of 1499 cm³. Combined system power 597 hp and torque 650 Nm are the figures to use when ranking this car against anything else in the same catalogue row. There is no “detuned” 1.5 DHT and no higher-output 1.5 DHT to split by horsepower: one name, one power number.

Performance vs weight: 0–100, top speed, kg per hp

1.5 DHT is measured at 5.8 seconds 0–100 and 180 km/h top speed. Kerb weight is 2260 kg. Mass per horsepower is 2260 ÷ 597 ≈ 3.79 kg/hp. Mass per newton-metre is 2260 ÷ 650 ≈ 3.48 kg/Nm.

Gross vehicle weight is 2893 kg. Payload (gross minus kerb) is 2893 − 2260 = 633 kg. At gross weight, mass per horsepower becomes 2893 ÷ 597 ≈ 4.85 kg/hp. The 0–100 figure of 5.8 s is tied to the catalogue row, not restated at 2893 kg.

Ground clearance is 180 mm. Wheel sizes are not measured. Front brakes: Ventilated disc. Rear brakes: Disc. Front and rear suspension: Independent, spring / Independent, spring.

For a buyer, the arithmetic is: 597 hp and 5.8 s sit on a 2260 kg kerb SUV 5-doors with AWD. The speed cap is 180, not an open figure. If the use case needs a higher listed top speed or a lighter kerb, this generation does not offer another version that changes those numbers.

MPG and tank: what is measured on 1.5 DHT

Mixed consumption for 1.5 DHT is 2.1. City consumption is not measured. Highway consumption is not measured. CO₂ is not measured. Eco class is not measured.

Tank capacity is 70. On the mixed figure alone, 70 ÷ 2.1 ≈ 33.3 tankfuls of mixed-cycle distance units per full tank if that 2.1 is used as a simple ratio. That ratio is not a measured range; range itself is not measured. The Plug-in label and the 2.1 mixed number are the economy story. Do not treat city or highway mpg as omitted because they “do not apply”: they are not measured.

Fuel grade is 95. There is no second 1.5 DHT on another fuel in this generation.

Dimensions and weight: clearance, tank, wheels

What is measured for the buyer’s packaging check:

Payload is 633 / 2260 ≈ 28.0% of kerb weight and 633 / 2893 ≈ 21.9% of gross. Clearance 180 mm does not change between versions because there are no other versions. Wheel size cannot be used as a trim differentiator: it is not measured.

Generations: what changed (and what did not)

1 generation is the only generation. Production start is 2024-12-01; stop is open (still current in the data). Body: SUV 5-doors. Version count: 1 — 1.5 DHT. There is no prior generation to subtract power, weight, or 0–100 against, and no restyling block inside this generation.

So “which generation to buy” collapses to this one: 1 generation, SUV 5-doors, from 2024-12-01. You cannot buy an older J8 generation from this catalogue. You cannot buy a later one either.

Gearbox, drive, and what extra money would buy (if a second version existed)

1.5 DHT is Automatic with 3 gears and AWD. There is no FWD 1.5 DHT, no extra gear count, and no manual. A buyer who wants AWD is not paying a listed delta versus a two-wheel-drive sibling: that sibling is not in the data. A buyer who wanted a different gearbox would be looking at a car that is not this model’s listed version.

Power 597 hp versus displacement 1499 cm³ is the same point as above: the “extra” in this row is the Plug-in Turbo combination that produces 597 hp and 650 Nm from 1499 cm³, not a second, larger engine you can tick on an order sheet.

Which version to choose

Choose 1.5 DHT if the measured package matches the use: Plug-in, 597 hp, 650 Nm, 5.8 s to 100, 180 km/h, mixed 2.1, AWD, Automatic 3, kerb 2260 kg, gross 2893 kg, tank 70, clearance 180 mm, fuel 95, body SUV 5-doors, 1 generation from 2024-12-01.

Do not choose it if you need a figure this row leaves not measured: city consumption, highway consumption, CO₂, eco class, power rpm, torque rpm, fuel system, wheel sizes. Those gaps are not filled by another J8 version in the same data.

There is no “higher hp 1.5 DHT” and no “lower hp 1.5 DHT” to split by power. There is no second generation whose restyle changed clearance, tank, or 0–100. The comparison table has one column. The arithmetic that remains useful is internal: ≈ 398.3 hp/l, ≈ 3.79 kg/hp at kerb, 633 kg payload, mixed 2.1 with a 70 tank.

Verdict: the Jaecoo J8 to buy, in this catalogue, is 1.5 DHT — because it is the only named version, and its numbers are the ones above.
