Infiniti QX30 SUV (2016-2020) running costs and reliability
Miles per pound (mpp)
Fuel economy
- Diesel offers predictably lower fuel consumption
- Both engines boast relatively low CO2
- Quite an expensive car to start off with
No surprises that the diesel QX30 is the pick of the two engines for low running costs, boasting 57.6mpg.
The petrol does okay though, with 42.2mpg – that’s not particularly bad but rivals claim to offer better economy whether petrol or diesel.
One of the biggest problems is the overall cost of the QX30 in the first place. This is not a cheap car and that will have a knock-on effect for monthly finance costs.
There isn’t a lot of choice when it comes to powertrain and CO2 emissions for both are middling at best.
You get 128g/km of CO2 with the diesel and 155g/km with the petrol, and no hybrid model in the pipeline to come and save the day.
While neither figure is all that high, it’s a shame there isn’t a lower emission model to help attract company car drivers looking for lower bills.
- Borrowed engineering should mean good reliability
- Engines and interior fittings used in lots of other cars
- InTouch infotainment system an unknown element
As with the Q30, we don’t think you’ll have many problems with the Infiniti QX30 reliability.
It’s based on the Mercedes-Benz GLA, which means its two powertrains have been tried and tested elsewhere. We also haven’t seen any significant GLA (or A-Class family) recalls.
The only unknown element really is the InTouch multimedia system – and an earlier version of that was used in the Q50 with no reported problems.
