The first article already covers what the JAC J7 (Binyue) is. This one is only about choosing between 2.0 MT and 2.4 MT on the numbers in the catalogue.
There is one generation of the JAC J7 (Binyue) (April 2007–December 2015, Sedan, two versions). The buy decision is between 2.0 MT and 2.4 MT. They share kerb weight (1470 kg), gross weight (1845 kg), ground clearance (125 mm), FWD, a 5-speed Manual, Gasoline, Inline 4, no boost, Distributed injection (multi-point), and Euro 3. They differ on displacement, power, torque, and top speed.

# JAC J7 (Binyue): which version to buy
There is one generation of the JAC J7 (Binyue) (April 2007–December 2015, Sedan, two versions). The buy decision is between 2.0 MT and 2.4 MT. They share kerb weight (1470 kg), gross weight (1845 kg), ground clearance (125 mm), FWD, a 5-speed Manual, Gasoline, Inline 4, no boost, Distributed injection (multi-point), and Euro 3. They differ on displacement, power, torque, and top speed. Fuel consumption, 0–100, tank size, and wheel sizes are not measured for either, so those cannot decide the purchase.
Specs that actually separate the two versions
| Version | hp | Nm | Displacement (cc) | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 2.0 MT | 95 | 172 | 1997 | Gasoline | 4 | Inline | No | Manual | FWD |
| 2.4 MT | 100 | 193 | 2350 | Gasoline | 4 | Inline | No | Manual | FWD |
2.4 MT adds 5 hp (100 vs 95), 4 kW (74 vs 70), and 21 Nm (193 vs 172). Both peak power at 5500 rpm and peak torque at 3000 rpm, so the extra output is not a different rev range. Displacement is 353 cc larger (2350 vs 1997). Top speed is 10 km/h higher (185 vs 175).
2.0 MT does not list valves per cylinder (not measured). 2.4 MT lists 4 valves per cylinder. That is a documentation gap on 2.0 MT, not a proven hardware difference you can bank on.
Engine: power per litre and what the extra displacement buys
2.0 MT makes 95 hp from 1997 cc → 47.6 hp per litre (95 ÷ 1.997). 2.4 MT makes 100 hp from 2350 cc → 42.6 hp per litre (100 ÷ 2.350).
The larger engine is less specific: 2.0 MT extracts about 5.0 hp more per litre. Torque density follows the same pattern: 2.0 MT 86.1 Nm/L (172 ÷ 1.997), 2.4 MT 82.1 Nm/L (193 ÷ 2.350). You pay 353 cc of extra capacity for 5 hp and 21 Nm, not for a denser tune.
Relative gains vs 2.0 MT:
- power: +5.3% (5 ÷ 95)
- torque: +12.2% (21 ÷ 172)
- displacement: +17.7% (353 ÷ 1997)
- top speed: +5.7% (10 ÷ 175)
Torque is the only output that moves in double digits. If the job is pulling load near the 1845 kg gross, 2.4 MT is the version that changes the arithmetic. If the job is highway indicated speed, 10 km/h is a small step.
Both are Gasoline, Inline 4, No boost, Distributed injection (multi-point). There is no diesel, no automatic, no AWD, and no second generation in this data set. You are not choosing fuel type, gearbox family, or drive layout — only size of the same layout.
Performance and mpg: what is measured, what is not
0–100 is not measured for 2.0 MT and not measured for 2.4 MT. Do not treat either as the quicker car off the line; the catalogue does not time it.
Top speed is measured: 175 km/h (2.0 MT), 185 km/h (2.4 MT). That is the only performance figure you can rank.
City, highway, and combined consumption are not measured for either version. MPG cannot pick a winner. 2.4 MT has 17.7% more displacement at the same 1470 kg kerb weight; that often implies more fuel, but this catalogue does not measure it, so it is not a fact here.
CO2 is not measured. Euro class is the same: Euro 3 on both.
Dimensions, weight, kg per horsepower
Kerb 1470 kg and gross 1845 kg are identical. Payload arithmetic is the same: 1845 − 1470 = 375 kg on both.
Ground clearance 125 mm on both. Tank not measured. Wheel sizes not measured. Front and rear suspension: Independent, spring. Front and rear brakes: Disc (as labelled in the data). None of those split the versions.
Weight per horsepower:
- 2.0 MT: 1470 ÷ 95 = 15.5 kg/hp
- 2.4 MT: 1470 ÷ 100 = 14.7 kg/hp
2.4 MT is 0.8 kg/hp lighter in that ratio (about 5.1% less mass per hp). Combined with +21 Nm, it is the less burdened car on paper. Combined with identical 125 mm clearance and identical FWD Manual 5-speed, it is not a different vehicle in stance or layout.
Generations: nothing later to wait for
One generation, April 2007 to December 2015, Sedan, two versions. There is no restyle generation and no second generation in the data. You cannot buy a later J7 (Binyue) with a different gearbox, drive, or body from this catalogue. The comparison is not gen-vs-gen; it is 2.0 MT vs 2.4 MT inside the same years.
Both versions run the full window 2007-04-01 to 2015-12-31. There is no early-only or late-only engine in these rows.
Reliability and problems
The data set does not list failure rates, recalls, or common faults. Reliability is not measured here. Shared items (FWD, Manual 5, Gasoline multi-point, Euro 3, same weights) mean you are not choosing a different driveline architecture. Valves per cylinder is measured only on 2.4 MT (4); on 2.0 MT it is not measured — do not invent a valve-train story from that blank.
Which version to choose
Choose 2.4 MT if you want the higher measured outputs: 100 hp, 193 Nm, 185 km/h, 14.7 kg/hp. The extra 21 Nm (+12.2%) is the largest useful gap. Same 1470 kg kerb, same 375 kg between kerb and gross, same 5-speed Manual and FWD — the larger engine is the only upgrade path in this model.
Choose 2.0 MT if you want the smaller 1997 cc unit with the higher specific output (47.6 hp/L vs 42.6) and you accept 95 hp, 172 Nm, and 175 km/h. You give up 5 hp and 10 km/h of top speed. Consumption is not measured, so you cannot claim it is cheaper to run from these figures.
Do not choose on 0–100, mpg, tank, wheels, or a later generation: all of those are not measured or not present.
There is no third version. No automatic, no all-wheel drive, no extra body. If you need those, they are not in JAC J7 (Binyue) as listed.
Bottom line: 2.4 MT is the stronger of two otherwise identical Sedans; 2.0 MT is the smaller-displacement twin with almost the same power (5 hp less) and clearly less torque (21 Nm less). Use torque and top speed if you must pick; do not use fuel use or sprint times — they are not measured.
