If your priority is reducing fuel cost, this specification deserves a careful look before you commit.

It also suits owners whose driving and fuel budget can accommodate an EPA estimate of $4,550 per year.

Trade-offs

The 20 MPG highway rating is higher than the 16 MPG city rating, so frequent urban driving will not match its highway efficiency.

Gasoline power, 18 MPG combined economy, and 504 grams of CO2 per mile define the running-cost and emissions trade-off.

Verdict

Choose the 2026 Infiniti QX80 2WD if rear-wheel drive and SUV body style matter more than minimizing fuel spending. Its 18 MPG combined rating gives a straightforward expectation, while the $4,550 annual estimate puts the ongoing cost in clear terms. Highway trips return the stronger 20 MPG figure, but city use falls to 16 MPG. The 3.5-liter turbo six-cylinder and automatic transmission complete a conventional gasoline setup, with no alternate fuel figure listed here.
