JAC J3 (Tongyue, Tojoy): which version to buy and why

If you are choosing a JAC J3 (Tongyue, Tojoy), the catalogue has one generation (2009–2015) and two versions, both named 1.3 MT and both rated 99 hp. The extra money, if any, does not buy more power, a larger engine, a different gearbox, or a different drive layout.

If you are choosing a JAC J3 (Tongyue, Tojoy), the catalogue has one generation (2009–2015) and two versions, both named 1.3 MT and both rated 99 hp. The extra money, if any, does not buy more power, a larger engine, a different gearbox, or a different drive layout. It buys a 20 km/h higher listed top speed (180 vs 160), a different front-brake specification (Disc vs Ventilated disc), and a different measured 0–100 figure (not measured vs 16 s). Both cars are Sedan, Gasoline, 4 Inline, No boost, Front, transverse, 5 Manual, FWD, 1100 kg kerb, 1475 kg gross, 160 mm ground clearance, 45 L tank, Euro 4.

There is no second generation to jump to. The decision is which 1.3 MT to take inside generation 1.

Specs that both 1.3 MT versions share

Both versions use a 1332 cm³ Gasoline engine, 4 cylinders, Inline, 4 valves per cylinder, No boost, Front, transverse, Distributed injection (multi-point), fuel 95. Output is 99 hp (73 kW) at 6000 rpm and 124 Nm at 4000 rpm. Gearbox is Manual, 5 speeds. Drive is FWD.

Kerb weight 1100 kg, gross 1475 kg, tank 45 L, clearance 160 mm, wheels not measured, CO2 not measured, city / highway / combined consumption not measured, compression ratio not measured, bore × stroke not measured. Rear brakes not measured. Front and rear suspension: Independent, spring.

Power per litre, using the given displacement: 99 / 1.332 ≈ 74.3 hp per litre (73 / 1.332 ≈ 54.8 kW per litre). Torque per litre: 124 / 1.332 ≈ 93.1 Nm per litre. Kerb weight per horsepower: 1100 / 99 ≈ 11.1 kg per hp. Gross weight per horsepower: 1475 / 99 ≈ 14.9 kg per hp. These ratios are identical on both 1.3 MT rows because power, displacement, and both mass figures are identical.

Generations: what changed (and what did not)

1 generation (2009-01-01 to 2015-12-31) is the only generation: body Sedan, 2 versions. Both versions sit in this generation. There is no restyling listed as a separate generation.

The earlier 1.3 MT is dated 2009-01-01 to 2015-12-31. The later 1.3 MT is dated 2010-01-01 to 2015-12-31. From 2010 through 2015 both rows overlap. The 2009 start is the only calendar gap: one 1.3 MT exists a year before the other.

What generation 1 does not change between the two rows: hp, kW, rpm, Nm, displacement, fuel type, cylinders, layout, boost, engine position, injection type, gearbox type, gear count, drive, tank, Euro class, kerb, gross, clearance, suspension wording.

What it does change: top speed, whether 0–100 is measured, front-brake wording, and the start year.

Engine and gearbox table (both versions named 1.3 MT)

Same name, same 99 hp: separate them by top speed and years, not by a second power figure.

Performance and economy: the only numbers that split the two

1.3 MT (2009–2015, 99 hp): 0–100 16 s, top speed 160. City mpg not measured, highway not measured, combined not measured, CO2 not measured.

1.3 MT (2010–2015, 99 hp): 0–100 not measured, top speed 180. City mpg not measured, highway not measured, combined not measured, CO2 not measured.

Arithmetic on the measured tops: 180 − 160 = 20 km/h. Relative to 160, 180 is 12.5% higher. Relative to 180, 160 is 11.1% lower.

The 16 s 0–100 belongs only to the 160 km/h 1.3 MT. The 180 km/h 1.3 MT does not carry a 0–100 in this dataset; writing 16 s onto that row would be invention. There is no consumption figure to convert into mpg for either car.

If the buying question is “which is quicker to 100,” only one version answers: the 1.3 MT with 16 s. If the question is “which lists a higher top speed,” the other 1.3 MT answers: 180 vs 160. Those two answers do not come from the same row.

Dimensions, weight, tank: nothing to trade

Kerb 1100 kg and gross 1475 kg on both. Payload from those two figures: 1475 − 1100 = 375 kg, same on both 1.3 MT. Ground clearance 160 mm both. Tank 45 L both. Wheel size not measured on both.

Weight per hp does not improve from one version to the other. Tank-to-kerb is 45 / 1100 ≈ 0.041 L per kg on both. There is no “lighter 1.3 MT” and no “larger-tank 1.3 MT” in the data.

Front brakes differ: Disc on the 2010–2015 1.3 MT (top 180); Ventilated disc on the 2009–2015 1.3 MT (top 160). Rear brakes not measured on both. That is the only chassis wording that is not copy-identical.

Which version to choose

Choose the 1.3 MT dated 2009–2015 (99 hp, top 160) if you want the only measured 0–100 (16 s) and the Ventilated disc front brakes. You accept a 160 top speed, 20 km/h below the other row. Engine, gearbox, drive, mass, tank, clearance, Euro 4, and 11.1 kg/hp stay the same. This row also covers 2009, which the other row does not.

Choose the 1.3 MT dated 2010–2015 (99 hp, top 180) if the listed 180 top speed is the figure you are buying. You give up a published 0–100 (not measured on this row) and take front brakes listed as Disc rather than Ventilated disc. Power is still 99 hp and 124 Nm; you are not buying more engine.

Do not choose between generations. There is 1 generation. There is no later J3 (Tongyue, Tojoy) in this catalogue with more hp, a different gearbox, or AWD.

Do not expect a power or economy gap. Both 1.3 MT versions are 99 hp, 73 kW, 124 Nm, 1332 cm³, Gasoline, No boost, 5 Manual, FWD. Consumption is not measured twice; you cannot rank mpg from these rows.

What the “extra” does not buy. Same displacement, same cylinders (4 Inline), same boost (No), same gearbox (5 Manual), same drive (FWD), same 1100 / 1475 kg, same 45 L, same 160 mm, same Euro 4. The spread in the table is 20 km/h of top speed, presence or absence of a 16 s 0–100, brake wording, and a 2009 vs 2010 start.

Power density as a buying filter. 74.3 hp/L and 11.1 kg/hp describe both cars. If you wanted a different litre-output or a lighter kg/hp, this model’s two versions do not offer it.

Reliability and problems. This dataset has no failure rates, no service intervals, and no common-fault list. Those searches cannot be answered from the numbers given. What can be answered: both versions are Gasoline, Euro 4, fuel 95, the same output and the same kerb weight.

Practical pick in one line. If you need a published sprint figure, take 1.3 MT (2009–2015, 99 hp, 16 s, 160 km/h, Ventilated disc). If you need the higher listed top speed, take 1.3 MT (2010–2015, 99 hp, 0–100 not measured, 180 km/h, Disc). Every other measured spec in the launch data is the same car twice.
