BYD F8 (S8): which version to buy
There is one production window and one catalogue version of the BYD F8 (S8): generation 1 generation (2009-01-01 to 2010-12-31), Cabrio body, and the single trim 2.0 MT. If you are choosing “which F8 (S8) to buy,” the data does not offer a second engine, a second gearbox, a restyle, or a later generation to trade up to.
There is one production window and one catalogue version of the BYD F8 (S8): generation 1 generation (2009-01-01 to 2010-12-31), Cabrio body, and the single trim 2.0 MT. If you are choosing “which F8 (S8) to buy,” the data does not offer a second engine, a second gearbox, a restyle, or a later generation to trade up to. The decision is whether 2.0 MT matches what you need, not which sibling to pick. The numbers below are only those recorded for 2.0 MT; anything not recorded is marked not measured.
Which generation changed what
1 generation is the whole model life: start 2009-01-01, stop 2010-12-31, 1 version, body Cabrio. There is no second generation in the data, so there is no later cabin, no later drivetrain, and no restyling line that belongs inside another generation. Buying “an F8 (S8)” and buying 1 generation 2.0 MT are the same choice.
Because only one generation exists, “what the extra generation buys” is not a comparison you can make on these figures. What you can do is judge 2.0 MT on its own arithmetic: how much power it makes per litre, how much kerb weight sits on each horsepower, how much payload remains under the gross figure, and which performance and economy fields were never measured.
BYD F8 (S8) specs: the only version
| Version | hp | Nm | Displacement (cc) | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 2.0 MT | 140 | 186 | 1991 | 95 | 4 | Inline | No | Manual | FWD |
2.0 MT is a Gasoline engine, 4 cylinders, Inline, 4 valves per cylinder, boost No, Front, transverse, fuel system Distributed injection (multi-point). Peak power is 140 hp / 102 kW at 6000 rpm; peak torque is 186 Nm at 4000 rpm. The gearbox is Manual with 5 gears; drive is FWD. Compression ratio is not measured. Bore and stroke are not measured.
Engine: power per litre and what 140 hp actually is
Displacement is 1991 cc, so the working volume is 1.991 litres.
- Power per litre for 2.0 MT: 140 ÷ 1.991 ≈ 70.3 hp per litre.
- Torque per litre: 186 ÷ 1.991 ≈ 93.4 Nm per litre.
- kW per litre: 102 ÷ 1.991 ≈ 51.2 kW per litre.
Boost is No, so those ratios are naturally aspirated figures, not a turbo or supercharger result. Peak power sits at 6000 rpm and peak torque at 4000 rpm: 2000 rpm apart. That gap is the character of this engine as recorded: torque is not quoted at a low idle band, and the 140 hp number is tied to 6000 rpm. There is no second engine in the catalogue to buy if you wanted more hp/litre or a lower rpm for peak torque.
Fuel is 95. Eco class is not measured. CO2 is not measured. You cannot rank 2.0 MT against a diesel, a hybrid, or a later petrol tune of the same model, because none of those versions exist in the data.
Performance and mpg: what was measured, what was not
For 2.0 MT:
- 0–100: 10.2 s
- Top speed: 185
- City consumption: not measured
- Highway consumption: not measured
- Combined consumption: not measured
- CO2: not measured
- Eco class: not measured
“Which version is quicker” is not a question with two answers. 10.2 s to 100 and 185 top speed are the only acceleration and speed pair in the file. There is no automatic, no higher-output petrol, and no later generation with a different 0–100.
“Which version uses less fuel” cannot be answered from these data. City, highway, and mixed consumption for 2.0 MT are all not measured. A buyer who needs a documented mpg figure does not get one here; that is a gap in the record, not a reason to invent a number. Tank volume is 50, so range in kilometres is also not measured until consumption is known.
If the buying filter is “I need a measured 0–100 under 10 seconds,” 2.0 MT at 10.2 s does not meet that filter. If the filter is “I need a documented combined mpg,” 2.0 MT fails that filter because the value is not measured. If the filter is “I will accept 10.2 s and 185 and I do not require a consumption figure in the catalogue,” then 2.0 MT is still the only version that exists.
Dimensions and weight: kg per hp and what the extra mass is for
For 2.0 MT:
- Kerb weight: 1525
- Gross weight: 1980
- Ground clearance: 150
- Fuel tank: 50
- Wheel sizes: not measured
Payload from the two mass figures: 1980 − 1525 = 455. That 455 is people, cargo, and fluids above kerb, up to the recorded gross. It is not a second trim with a different payload; it is the only payload you can calculate from these two masses.
Weight per horsepower: 1525 ÷ 140 ≈ 10.89 kg per hp (kerb). On gross mass: 1980 ÷ 140 ≈ 14.14 kg per hp. Those ratios tell you how much mass each horsepower of 2.0 MT has to move. There is no lighter or heavier sister version in the data to compare; you either accept ≈10.89 kg/hp at kerb or you look outside this model.
Ground clearance is 150. Wheel size is not measured, so you cannot choose a version by tyre diameter or by a documented plus-size option. Front suspension is Independent, spring; rear suspension is Independent, spring. Front brakes are Ventilated disc; rear brakes are Disc. Those chassis labels are the same for the only version; there is no sport pack, no AWD, and no different brake specification in the table.
Which version to choose
Choose 2.0 MT if you want this model at all. It is the only version of BYD F8 (S8) 1 generation: Gasoline, 1991 cc, 140 hp at 6000 rpm, 186 Nm at 4000 rpm, boost No, Manual 5, FWD, Cabrio, kerb 1525, gross 1980, tank 50, clearance 150, 0–100 10.2 s, top speed 185.
What “the extra money” would buy on this model is not in the data: there is no second row with more hp, a different gearbox, or a later generation. Arithmetic on the one row:
- ≈70.3 hp/L and ≈93.4 Nm/L on 1991 cc with boost No.
- ≈10.89 kg per hp at 1525 kerb.
- 455 kg between 1525 kerb and 1980 gross.
- Peak torque 4000 rpm versus peak power 6000 rpm.
Do not treat missing fields as if they were zero or as if they did not exist. Consumption (city, highway, mixed), CO2, eco class, compression ratio, bore and stroke, and wheel sizes are not measured. A purchase that depends on mpg, tyre size, or emissions class cannot be justified from this catalogue line.
There is no “other F8 (S8)” to pick. Same name 2.0 MT does not appear twice at different outputs; you do not need to split two 2.0 MT rows by horsepower. Generation count is 1. Body count in the data is Cabrio only. If Manual, FWD, 140 hp, 10.2 s, and Cabrio are acceptable and you can live with consumption not measured, 2.0 MT is the version. If you needed a second engine, an automatic, a different drive, a restyle, or a later generation, this model’s data does not contain that choice.
