Infiniti JX

Infiniti JX: Which Version Should You Buy?

The Infiniti JX was produced from 2012 through 2014 as a single-generation SUV 5-doors. The catalogue lists two versions, both named 3.5 CVT, with the same 265 hp Gasoline engine and Variable gearbox. The meaningful choice is therefore the drivetrain: one version has AWD, while the other has FWD.

The Infiniti JX was produced from 2012 through 2014 as a single-generation SUV 5-doors. The catalogue lists two versions, both named 3.5 CVT, with the same 265 hp Gasoline engine and Variable gearbox. The meaningful choice is therefore the drivetrain: one version has AWD, while the other has FWD. The FWD model is 141 kg lighter, reaches 100 km/h 0.4 seconds sooner, and has a top speed 4 km/h higher. The AWD version uses less fuel on the highway and in combined driving according to the supplied figures, while providing AWD rather than FWD.

Infiniti JX generations: what changed?

There is only one Infiniti JX generation in the data, covering 2012–2014. It has an SUV 5-doors body and two listed versions. No separate restyling or later generation is identified, so there is no generation-to-generation mechanical comparison to make. Buyers comparing cars from different years within this production period should assess them against the same two catalogue specifications rather than assume that a newer year represents a different generation.

Infiniti JX35 engine and specs

Both 3.5 CVT versions use the same 3,498 cc Gasoline engine. It has 6 cylinders in a V-shaped layout, 4 valves per cylinder, no boost, and distributed injection (multi-point). Output is 265 hp (195 kW) at 6,400 rpm, while torque is 336 Nm at 4,400 rpm. The compression ratio is 10.3, and the bore and stroke are 95.5 × 81.4. With approximately 75.8 hp per litre, neither drivetrain has a power-density advantage.

For searches concerning the Infiniti JX35 transmission, the supplied specification identifies the gearbox as Variable in both versions. The data does not include transmission reliability, maintenance intervals, problems, or repair history. Engine oil type, engine oil capacity, air-filter details, alternator specifications, engine mounts, warning-light diagnosis, and engine diagrams are also not measured.

Infiniti JX35 performance and mpg comparison

The lighter FWD 3.5 CVT has the performance advantage. It accelerates from 0 to 100 km/h in 8.0 seconds, compared with 8.4 seconds for the AWD 3.5 CVT. Its maximum speed is 194 km/h, versus 190 km/h for AWD.

Fuel consumption produces a less obvious result. The FWD version uses 13.1 l/100 km in the city, which is 1.3 l/100 km less than the AWD version’s 14.4 l/100 km. On the highway, however, AWD is rated at 8.5 l/100 km compared with 9.8 l/100 km for FWD, a 1.3 l/100 km advantage for AWD. Combined consumption is 10.7 l/100 km for AWD and 11.2 l/100 km for FWD, making AWD lower by 0.5 l/100 km in the supplied combined figures.

CO₂ emissions and environmental class are not measured for either 3.5 CVT version.

Infiniti JX35 dimensions, weight, and chassis specs

The supplied data does not measure exterior dimensions or cargo dimensions, so length, width, height, wheelbase, and load-space measurements cannot be compared. Ground clearance is 180 mm for both versions, and each has a 74-litre fuel tank. Wheel sizes are not measured for either version.

Kerb weight is where the versions differ substantially. The AWD 3.5 CVT weighs 2,082 kg, while the FWD 3.5 CVT weighs 1,941 kg. That makes FWD 141 kg lighter. With equal power, the AWD model carries approximately 7.86 kg per horsepower, compared with approximately 7.32 kg per horsepower for FWD. This 0.54 kg-per-horsepower advantage helps explain why the FWD version is quicker in the supplied acceleration figures.

Gross weight is 2,680 kg for the AWD version. Gross weight for the FWD version is not measured, so gross-weight capacity cannot be compared.

Both versions have Independent, spring front and rear suspension. Both also use Ventilated disc front brakes and Disc ventilated rear brakes.

Infiniti JX35 reliability, problems, and price

Reliability and problem-frequency data are not measured for either 3.5 CVT version. The catalogue figures therefore cannot establish whether the AWD or FWD drivetrain is more reliable, nor can they support claims about engine, Variable transmission, alternator, or electrical problems.

Price, depreciation, and cars for sale are not measured. It is consequently impossible to calculate what extra money the AWD system costs or whether either version offers better value at a particular asking price. A price comparison should not substitute unsupported market figures for the catalogue data.

Which Infiniti JX version should you buy?

Choose the FWD 3.5 CVT if lower kerb weight, quicker acceleration, higher maximum speed, and lower city consumption matter most. It is 141 kg lighter, reaches 100 km/h 0.4 seconds sooner, is 4 km/h faster at maximum speed, and uses 1.3 l/100 km less in the city. Because both versions produce 265 hp and 336 Nm, these advantages come without sacrificing listed engine output.

Choose the AWD 3.5 CVT if AWD is the priority or if the supplied highway and combined consumption figures better match your driving. It uses 1.3 l/100 km less on the highway and 0.5 l/100 km less in combined driving than the FWD version. It has the same 3,498 cc Gasoline engine, Variable gearbox, 180 mm ground clearance, and 74-litre tank, but its greater 2,082 kg kerb weight corresponds with slower acceleration.

On specifications alone, the FWD 3.5 CVT is the stronger performance and city-driving choice. The AWD 3.5 CVT is the more appropriate selection when the drivetrain itself and the lower listed highway or combined consumption are more important. No generation upgrade, reliability record, price premium, or equipment difference is available in the data to overturn that comparison.
