How it compares

Against the average compact cars in this dataset (about 29 MPG), the WRX sits roughly 8 MPG below that mark on average, making it a thirstier-than-average choice for its class.

Five-year fuel cost

Fuelling a WRX for five years at the EPA's 15,000-mile basis costs roughly $17,250 to $22,250, averaging about $19,750 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 WRX varies by about 5 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 WRX 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 WRX's average combined economy improved from about 21 to 21 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 WRX has the strongest average combined economy in this database at about 21 MPG, while the 2018 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.
