Fuel economy by year

How it compares

Against the average large cars in this dataset (about 29 MPG), the G90 sits roughly 10 MPG below that mark on average, making it a thirstier-than-average choice for its class.

Five-year fuel cost

Fuelling a G90 for five years at the EPA's 15,000-mile basis costs roughly $20,000 to $22,250, averaging about $21,125 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 2017 and 2020 the G90's average combined economy improved from about 19 to 19 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 G90 has the strongest average combined economy in this database at about 19 MPG, while the 2017 is the lowest at about 19 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.
