JAC J6 (Heyue RS): Which Version Should You Buy?
The JAC J6 (Heyue RS) range offers five Gasoline versions from its single generation, produced from September 2013 to December 2015 as a Compact Van. The main choice is between the 1.5 MT, two distinct 1.8 MT versions, the 1.8 AT, and the 2.0 MT.
The JAC J6 (Heyue RS) range offers five Gasoline versions from its single generation, produced from September 2013 to December 2015 as a Compact Van. The main choice is between the 1.5 MT, two distinct 1.8 MT versions, the 1.8 AT, and the 2.0 MT. The 112 hp 1.8 MT has the strongest overall power-to-weight figures, the 1.8 AT is the only Automatic option, and the 2.0 MT delivers the highest torque at 190 Nm. Buyers prioritizing the lowest listed displacement can choose the 1.5 MT, while those wanting the highest listed top speed should consider the 112 hp 1.8 MT.
Generation and version choice
The JAC J6 (Heyue RS) has one generation in the supplied catalogue data. The 1 generation ran from September 2013 through December 2015 and used a Compact Van body. It contains five versions, so there is no later generation to compare and no recorded generational change in engine, transmission, body style, or performance.
Two versions share the exact name 1.8 MT and must be distinguished by output. One produces 105 hp and 165 Nm, while the other produces 112 hp and 146 Nm. They also differ in kerb weight, ground clearance, top speed, engine placement data, and specified fuel information.
Engine and specs comparison
Every JAC J6 (Heyue RS) version has a naturally aspirated Gasoline engine with 4 Inline cylinders, 4 valves per cylinder, and distributed multi-point injection. Every version is FWD. Four use a 5-speed Manual gearbox, while the 1.8 AT uses a 4-speed Automatic.
| Version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 1.5 MT | 83 hp (61 kW) at 6000 rpm | 146 Nm at 4000 rpm | 1500 cc | Gasoline; grade not measured | 4 | Inline | No | 5-speed Manual | FWD |
| 1.8 MT (105 hp) | 105 hp (77 kW) at 6500 rpm | 165 Nm at 5000 rpm | 1834 cc | Gasoline; grade not measured | 4 | Inline | No | 5-speed Manual | FWD |
| 1.8 AT | 105 hp (77 kW) at 6500 rpm | 165 Nm at 5000 rpm | 1834 cc | Gasoline; grade not measured | 4 | Inline | No | 4-speed Automatic | FWD |
| 1.8 MT (112 hp) | 112 hp (82 kW) at 6000 rpm | 146 Nm at 4000 rpm | 1834 cc | Gasoline, 95 | 4 | Inline | No | 5-speed Manual | FWD |
| 2.0 MT | 100 hp (74 kW) at 6000 rpm | 190 Nm at 4500 rpm | 1997 cc | Gasoline; grade not measured | 4 | Inline | No | 5-speed Manual | FWD |
The 1.5 MT produces about 55.3 hp per litre. The 105 hp 1.8 MT and 1.8 AT each produce about 57.3 hp per litre, while the 112 hp 1.8 MT reaches about 61.1 hp per litre. The 2.0 MT produces about 50.1 hp per litre. On this measure, the 112 hp 1.8 MT makes the most power from each litre of displacement.
The 2.0 MT leads for torque with 190 Nm, which is 25 Nm more than either 105 hp 1.8 version and 44 Nm more than the 1.5 MT or 112 hp 1.8 MT. Its 100 hp output, however, is 12 hp below the 112 hp 1.8 MT despite having 163 cc more displacement.
The two 105 hp versions have identical listed engine output: both provide 105 hp at 6500 rpm and 165 Nm at 5000 rpm from 1834 cc. Their defining difference is the transmission: the 1.8 MT has a 5-speed Manual, whereas the 1.8 AT has a 4-speed Automatic.
Performance, top speed, and economy
Acceleration from 0 to 100 km/h is not measured for any of the five versions. City fuel consumption, highway fuel consumption, combined fuel consumption, and CO₂ emissions are also not measured for every version. Consequently, the supplied figures cannot establish which version accelerates fastest or uses the least fuel.
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| 1.5 MT | not measured | 175 km/h | not measured | not measured | not measured | not measured |
| 1.8 MT (105 hp) | not measured | 175 km/h | not measured | not measured | not measured | not measured |
| 1.8 AT | not measured | 175 km/h | not measured | not measured | not measured | not measured |
| 1.8 MT (112 hp) | not measured | 180 km/h | not measured | not measured | not measured | not measured |
| 2.0 MT | not measured | 175 km/h | not measured | not measured | not measured | not measured |
The 112 hp 1.8 MT is the only version rated at 180 km/h. Its listed top speed is 5 km/h higher than the 175 km/h specified for every other version. All five versions meet Euro 4.
Weight, ground clearance, tank, and wheel sizes
The 1.5 MT, 105 hp 1.8 MT, 1.8 AT, and 2.0 MT each have a listed kerb weight of 1500 kg. The 112 hp 1.8 MT weighs 1450 kg, making it 50 kg lighter. Gross weight is not measured for four versions; only the 112 hp 1.8 MT has a stated gross weight, at 1905 kg.
| Version | Kerb weight | Gross weight | Ground clearance | Fuel tank | Wheel sizes |
|---|---|---|---|---|---|
| 1.5 MT | 1500 kg | not measured | 170 mm | 55 L | not measured |
| 1.8 MT (105 hp) | 1500 kg | not measured | 170 mm | 55 L | not measured |
| 1.8 AT | 1500 kg | not measured | 170 mm | 55 L | not measured |
| 1.8 MT (112 hp) | 1450 kg | 1905 kg | 180 mm | 55 L | not measured |
| 2.0 MT | 1500 kg | not measured | 170 mm | 55 L | not measured |
The 112 hp 1.8 MT combines the lowest kerb weight with the highest output. It carries about 12.9 kg per horsepower, compared with about 14.3 kg per horsepower for the 105 hp 1.8 MT and 1.8 AT, 15.0 kg per horsepower for the 2.0 MT, and 18.1 kg per horsepower for the 1.5 MT. This comparison favors the 112 hp 1.8 MT, although actual acceleration remains not measured.
Ground clearance is 180 mm for the 112 hp 1.8 MT and 170 mm for all other versions, a difference of 10 mm. Every version has a 55 L fuel tank. Wheel sizes are not measured for any version.
All five versions use Independent, spring front and rear suspension with Disc front and rear brakes. The 112 hp 1.8 MT is the only entry whose engine position is measured: Front, transverse. Engine position is not measured for the other four versions.
Which JAC J6 (Heyue RS) version should you buy?
The 1.8 MT with 112 hp is the strongest numerical all-round choice. It has the highest power, the best power per litre, the lowest weight per horsepower, the lightest kerb weight, the greatest ground clearance, and the highest top speed. Compared with the 105 hp 1.8 MT, it adds 7 hp, removes 50 kg, raises clearance by 10 mm, and increases top speed by 5 km/h. The trade-off is 19 Nm less torque: 146 Nm rather than 165 Nm.
Choose the 1.8 AT if an Automatic gearbox is the priority. It is the only Automatic version and pairs its 4-speed transmission with 105 hp and 165 Nm. Its engine output, 1500 kg kerb weight, 170 mm clearance, and 175 km/h top speed match the listed figures of the 105 hp 1.8 MT, leaving gearbox type and gear count as the principal recorded differences.
The 105 hp 1.8 MT is the direct Manual alternative to the 1.8 AT. It retains the same 105 hp and 165 Nm but uses a 5-speed Manual instead of a 4-speed Automatic. Because acceleration and consumption are not measured, the data do not prove that either transmission is quicker or more economical.
Choose the 2.0 MT when maximum listed torque matters most. Its 190 Nm advantage is clear, but it does not lead in power, power per litre, kerb weight, clearance, or top speed. It has 17 hp more than the 1.5 MT, yet its weight remains 1500 kg and its top speed remains 175 km/h.
The 1.5 MT is the smallest-displacement choice at 1500 cc. It produces 83 hp and 146 Nm and uses the same 5-speed Manual, FWD layout, 55 L tank, 170 mm clearance, and 175 km/h top-speed rating found on several larger-engine versions. Its drawback in the supplied specifications is the highest weight per horsepower, at about 18.1 kg per horsepower.
No prices are provided, so the extra cost of any engine or transmission cannot be quantified. Reliability and problems are also not measured in the supplied data. On specifications alone, the 112 hp 1.8 MT offers the broadest set of numerical advantages; the 1.8 AT is the clear choice for Automatic transmission; and the 2.0 MT is the option for the highest torque.
