Infiniti QX30: Which Version Should You Buy?
The Infiniti QX30 has one generation, built from November 2015 to January 2020 as an SUV 5-doors. Choosing between its two versions therefore comes down to the powertrain rather than a generational change: 2.1 DSG prioritizes lower fuel consumption and lower kerb weight, while 2.0T Luxe Tech delivers stronger acceleration, more horsepower, and a higher top speed.
The Infiniti QX30 has one generation, built from November 2015 to January 2020 as an SUV 5-doors. Choosing between its two versions therefore comes down to the powertrain rather than a generational change: 2.1 DSG prioritizes lower fuel consumption and lower kerb weight, while 2.0T Luxe Tech delivers stronger acceleration, more horsepower, and a higher top speed. Both have AWD, a 7-speed Robotic gearbox, turbocharged inline 4-cylinder engines, 202 mm of ground clearance, and a 56-liter fuel tank.
Infiniti QX30 generations: what changed?
There is only one Infiniti QX30 generation in the supplied catalogue data, so there is no newer generation with revised engines, dimensions, or equipment to compare. The first generation ran from November 2015 until January 2020, used the SUV 5-doors body, and included two versions: 2.1 DSG and 2.0T Luxe Tech.
Consequently, searches for Infiniti QX30 2017 specs, Infiniti QX30 2018 specs, or 2019 Infiniti QX30 specs all fall within the same recorded generation. The data does not identify model-year revisions, restylings, or “years to avoid,” so reliability differences between individual years are not measured.
Infiniti QX30 engine specs compared
| Version | Power | Torque | Displacement | Fuel | Cylinders and layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 2.1 DSG | 170 hp (125 kW) at 3400–4000 rpm | 350 Nm at 1400–3400 rpm | 2143 cc | Diesel | 4, Inline | Turbo | 7-speed Robotic | AWD |
| 2.0T Luxe Tech | 211 hp (155 kW) at 5500 rpm | 357 Nm at 1200–4000 rpm | 1991 cc | 95, Gasoline | 4, Inline | Turbo | 7-speed Robotic | AWD |
The 2.0T Luxe Tech produces 41 hp and 7 Nm more than the 2.1 DSG, despite having 152 cc less displacement. Its specific output is approximately 106 hp per liter, compared with approximately 79 hp per liter for the 2.1 DSG. That makes the Gasoline version the clear choice when power density and outright performance matter most.
The 2.1 DSG develops its 170 hp between 3400 and 4000 rpm, while its peak torque of 350 Nm is available from 1400 to 3400 rpm. The 2.0T Luxe Tech reaches 211 hp at 5500 rpm and provides 357 Nm across a broader 1200–4000 rpm range. Both engines are front-mounted and transverse, use 4 valves per cylinder, and have Turbo boost. The 2.0T Luxe Tech has Direct injection (direct); the fuel-system type for 2.1 DSG is not measured.
Compression ratio is 16.2 for 2.1 DSG and 9.8 for 2.0T Luxe Tech. Bore and stroke are 83 × 99 mm for 2.1 DSG and 83 × 92 mm for 2.0T Luxe Tech. Both versions meet Euro 6.
Infiniti QX30 performance, fuel economy, and mpg comparison
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| 2.1 DSG | 8.5 sec | 215 km/h | 6.0 L/100 km | 4.3 L/100 km | 4.9 L/100 km | 128 g/km |
| 2.0T Luxe Tech | 7.3 sec | 230 km/h | 9.5 L/100 km | 6.5 L/100 km | 7.6 L/100 km | 194 g/km |
The performance advantage belongs to 2.0T Luxe Tech. It reaches 100 km/h 1.2 seconds sooner and has a top speed 15 km/h higher than 2.1 DSG. Its 211 hp also gives it approximately 8.0 kg of kerb weight per horsepower, whereas 2.1 DSG carries approximately 9.5 kg per horsepower. Although the Gasoline car is 73 kg heavier, its additional 41 hp more than compensates in the power-to-weight comparison.
The efficiency advantage belongs decisively to 2.1 DSG. Compared with 2.0T Luxe Tech, it uses 3.5 L/100 km less in the city, 2.2 L/100 km less on the highway, and 2.7 L/100 km less combined. Its recorded CO₂ figure is also 66 g/km lower.
US mpg figures are not measured in the supplied data. The available consumption measurements are stated only in L/100 km, so they should not be replaced with an unverified mpg figure.
Infiniti QX30 dimensions, weight, and clearance
| Version | Kerb weight | Gross weight | Ground clearance | Fuel tank | Wheel sizes |
|---|---|---|---|---|---|
| 2.1 DSG | 1610 kg | 2075 kg | 202 mm | 56 L | not measured |
| 2.0T Luxe Tech | 1683 kg | 1990 kg | 202 mm | 56 L | not measured |
The 2.1 DSG is 73 kg lighter at kerb weight, but its gross weight is 85 kg higher than that of 2.0T Luxe Tech. Both provide the same 202 mm ground clearance and the same 56-liter tank capacity, so neither gains an advantage in those catalogue measurements.
Overall length, width, height, and wheelbase are not measured in the supplied data. Wheel sizes are also not measured for either version. Accordingly, a precise Infiniti QX30 size comparison cannot be made from these records.
Both versions use Independent, spring front and rear suspension. The 2.1 DSG has Ventilated disc front brakes and Disc rear brakes. The 2.0T Luxe Tech has Ventilated disc brakes at both the front and rear.
Infiniti QX30 reliability, reviews, and engine problems
Reliability ratings, repair histories, engine problems, oil capacity, oil specifications, air-filter details, and oil-reset procedures are not measured in the supplied data. It is therefore not possible to name an Infiniti QX30 year to avoid or claim that one of these two engines is more reliable.
The catalogue figures can support a performance-and-economy choice, but not a reliability verdict. When considering an individual Infiniti QX30 for sale, its price, condition, mileage, maintenance history, and location are also not measured here.
Which Infiniti QX30 version should you buy?
Choose 2.1 DSG if fuel consumption is the priority. It records 4.9 L/100 km combined against 7.6 L/100 km for 2.0T Luxe Tech, while still providing 350 Nm, AWD, and a 7-speed Robotic gearbox. It is also 73 kg lighter and produces 66 g/km less CO₂. The trade-off is slower acceleration, a lower top speed, and 41 hp less power.
Choose 2.0T Luxe Tech if acceleration and horsepower matter more. Its 211 hp and 357 Nm take it from 0 to 100 km/h in 7.3 seconds and on to 230 km/h. Compared with 2.1 DSG, that means 1.2 seconds quicker acceleration and 15 km/h more top speed, plus the stronger ratio of approximately 8.0 kg per horsepower. The cost in measurable terms is higher consumption in every recorded driving cycle and an additional 73 kg of kerb weight.
Price differences are not measured, so the data cannot show what the extra money buys or establish which version offers better financial value. On specifications alone, 2.1 DSG is the economy-led choice; 2.0T Luxe Tech is the performance-led choice.
