How it compares

Against the average large cars in this dataset (about 29 MPG), the Impala sits roughly 7 MPG below that mark on average, making it a thirstier-than-average choice for its class.

Five-year fuel cost

Fuelling a Impala for five years at the EPA's 15,000-mile basis costs roughly $13,000 to $16,250, averaging about $14,625 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 Impala 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 Impala 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 Impala's average combined economy slipped from about 22 to 22 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 Impala has the strongest average combined economy in this database at about 23 MPG, while the 2016 is the lowest at about 22 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.
