How it compares

Against the average small sport utility vehicle 4wd in this dataset (about 24 MPG), the NX sits roughly 4 MPG above that mark on average, making it a relatively efficient choice for its class.

Five-year fuel cost

Fuelling a NX for five years at the EPA's 15,000-mile basis costs roughly $10,250 to $16,500, averaging about $13,375 across the versions here. That is the energy bill alone — it excludes insurance, maintenance and depreciation, which for most owners together exceed what goes into the tank.

The range within the range

Economy across the NX varies by about 8 MPG between its most and least frugal versions, which run on gasoline and hybrid. Engine size, turbocharging, drivetrain and even wheel size explain most of that gap, so when you shop a used NX check which version you are looking at before comparing its running cost to another car.

How it changed over time

Between 2016 and 2020 the NX's average combined economy slipped from about 28 to 28 MPG. Redesigns, new engines and added hybrid or electric versions are usually what move the number, so the year you choose can matter as much as the model.

Best year for fuel economy

The 2016 NX has the strongest average combined economy in this database at about 27 MPG, while the 2017 is the lowest at about 26 MPG. If running cost is your priority, that is the year to target on the used market; later years may add equipment or safety features instead.
