BAIC BJ2020: which 2.5 MT to choose — 87 hp or 106 hp

If you are choosing a BAIC BJ2020, you are not choosing between generations. There is 1 generation (1989–2005), SUV cabriolet, and 2 versions, both named 2.5 MT. The split is power: 87 hp versus 106 hp. Everything else that is measured in the data is the same chassis, the same 2446 cm³ Gasoline engine family, the same Manual 4-speed AWD layout, the same 1580 kg kerb weight.

If you are choosing a BAIC BJ2020, you are not choosing between generations. There is 1 generation (1989–2005), SUV cabriolet, and 2 versions, both named 2.5 MT. The split is power: 87 hp versus 106 hp. Everything else that is measured in the data is the same chassis, the same 2446 cm³ Gasoline engine family, the same Manual 4-speed AWD layout, the same 1580 kg kerb weight. The extra 19 hp is the only real fork in the catalogue.

Specs that do not change between the two 2.5 MT versions

Both 2.5 MT (87 hp) and 2.5 MT (106 hp) share:

• Displacement 2446 cm³, fuel Gasoline, fuel grade 92, cylinders 4, layout Inline, valves per cylinder 2, boost No, feed Carburetor, compression 7.6, bore × stroke 92 × 92
• Gearbox Manual, gears 4, drive AWD
• Kerb weight 1580 kg, gross weight 2015 kg (payload 435 kg)
• Ground clearance 205 mm, tank 76 L
• Front suspension Independent, leaf spring, rear Dependent, leaf spring
• Front brakes Disc, rear Drum
• Production window 1989-01-01 to 2005-12-31
• Engine location: not measured
• Wheel sizes: not measured
• Eco class and CO2: not measured
• City / highway / combined consumption: not measured
• 0–100 km/h: not measured

So a “which generation” question does not apply: generation count is 1. A “which body” question does not apply: body is SUV cabriolet only. The buyer question is which of the two 2.5 MT outputs you want on the same 1580 kg AWD SUV cabriolet.

Engines and specs: both versions named 2.5 MT

Same name, same displacement, same Carburetor, same 7.6 compression. Different peak power and a small torque step.

What the extra 19 hp actually buys

Arithmetic on the given numbers:

• Power gap: 106 − 87 = 19 hp (+21.8%). In kilowatts: 78 − 64 = 14 kW.
• Torque gap: 180 − 173 = 7 Nm (+4.0%). Peak torque rpm is 3000 on both.
• Power per litre (2446 cm³ = 2.446 L): 87 / 2.446 ≈ 35.6 hp/L versus 106 / 2.446 ≈ 43.3 hp/L. The 106 hp 2.5 MT extracts about 7.8 hp more from each litre.
• Peak power rpm: 3800 on the 87 hp 2.5 MT, 4800 on the 106 hp 2.5 MT — 1000 rpm higher. The stronger version asks for more crank speed to deliver its extra 19 hp; torque still peaks at the same 3000 rpm.
• Weight per horsepower at 1580 kg kerb: 1580 / 87 ≈ 18.2 kg/hp versus 1580 / 106 ≈ 14.9 kg/hp. That is 3.3 kg/hp less mass per horsepower on the 106 hp version — about 18% less kg per hp.
• Gross-weight kg/hp: 2015 / 87 ≈ 23.2 kg/hp versus 2015 / 106 ≈ 19.0 kg/hp.
• Top speed: 110 km/h versus 125 km/h. Difference 15 km/h (+13.6%). That is the only measured performance figure that moves with power.
• 0–100 km/h: not measured on either 2.5 MT, so you cannot rank sprint from this catalogue.
• Fuel use (city, highway, mixed): not measured on either, so you cannot pick the 87 hp car as “the economy one” from these numbers. Tank is 76 L on both.

The extra output is almost all at the power peak, not in torque: +21.8% hp versus +4.0% Nm. If you care about the number on the power curve and the 125 km/h cap, the 106 hp 2.5 MT is the one that changes the sheet. If you care about low-rpm pull, the 7 Nm gap at the same 3000 rpm is small.

Performance and economy: measured vs not measured

Top speed is measured: 110 km/h for 2.5 MT (87 hp), 125 km/h for 2.5 MT (106 hp).

0–100 km/h is not measured for both.

mpg / L/100 km (city, highway, mixed) is not measured for both. There is no consumption row you can use to prefer one 2.5 MT over the other. CO2 is not measured. Eco class is not measured.

Range from tank size alone cannot be computed: you would need a consumption figure that is not in the data. The 76 L tank is identical, so it does not break the tie.

Dimensions, weight, ground clearance

No length / width / height / wheelbase figures are in the data. What is measured:

• Kerb 1580 kg, gross 2015 kg, payload 435 kg — same on 2.5 MT (87 hp) and 2.5 MT (106 hp)
• Ground clearance 205 mm — same
• Tank 76 L — same
• Wheel sizes — not measured on either

There is no “lighter 2.5 MT” and no “higher 2.5 MT”. Mass and clearance do not help you choose. The 106 hp version does not pay a weight penalty in this table: 1580 kg either way, so all of the 19 hp shows up in kg/hp.

Generations: nothing to trade across years of structure

1 generation, 1989–2005, 2 versions, body SUV cabriolet. Both 2.5 MT lines run the full window 1989-01-01–2005-12-31. There is no restyling generation in the data and no second body. You cannot buy a later generation for more gears, a different drive, or a different suspension: Manual 4, AWD, leaf-spring front Independent, leaf spring and rear Dependent, leaf spring, Disc front / Drum rear stay put.

Which version to buy

Choose 2.5 MT (106 hp) if the decision is about the numbers that actually differ: 106 hp / 78 kW at 4800 rpm, 180 Nm, 43.3 hp/L, 14.9 kg/hp, top speed 125 km/h. You get 19 hp and 7 Nm more than the other 2.5 MT at the same 2446 cm³, same 1580 kg, same AWD, same 4-speed Manual. That is the only “more car” the catalogue records.

Choose 2.5 MT (87 hp) if you want the same BJ2020 hardware at the lower output: 87 hp / 64 kW at 3800 rpm, 173 Nm, 35.6 hp/L, 18.2 kg/hp, top speed 110 km/h. Peak power arrives 1000 rpm earlier. You do not get a measured fuel-use advantage, a lower kerb weight, a larger tank, or more clearance — those are equal or not measured.

Do not choose by generation, body, gearbox, or drive. There is one generation, one SUV cabriolet, one Manual 4, one AWD. Do not choose by 0–100, mpg, wheels, CO2, or eco class: all not measured. Do not treat the two 2.5 MT names as the same car: they share the name and the 2446 cm³ Gasoline Inline 4, and they split at 87 versus 106 hp.

Short rule: same 1580 kg AWD SUV cabriolet, two 2.5 MT outputs. If 125 km/h and 19 extra hp matter, take 2.5 MT (106 hp). If they do not, 2.5 MT (87 hp) is the same measured chassis with a milder peak.
