How it compares

Against the average small station wagons in this dataset (about 35 MPG), the QX50 sits roughly 12 MPG below that mark on average, making it a thirstier-than-average choice for its class.

Five-year fuel cost

Fuelling a QX50 for five years at the EPA's 15,000-mile basis costs roughly $14,750 to $20,000, averaging about $17,375 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 QX50 varies by about 7 MPG between its most and least frugal versions, which run on gasoline. Engine size, turbocharging, drivetrain and even wheel size explain most of that gap, so when you shop a used QX50 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 QX50's average combined economy improved from about 20 to 26 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 2019 QX50 has the strongest average combined economy in this database at about 26 MPG, while the 2016 is the lowest at about 20 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.
