Fuel economy by year

How it compares

Against the average small sport utility vehicle 2wd in this dataset (about 26 MPG), the XT4 sits roughly 1 MPG below that mark on average, making it a thirstier-than-average choice for its class.

Five-year fuel cost

Fuelling a XT4 for five years at the EPA's 15,000-mile basis costs roughly $15,250 to $16,500, averaging about $15,875 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.

How it changed over time

Between 2019 and 2020 the XT4's average combined economy improved from about 25 to 25 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 2020 XT4 has the strongest average combined economy in this database at about 25 MPG, while the 2019 is the lowest at about 25 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.
