How to read this
Combined MPG blends EPA city and highway testing into one number — higher is better. Annual fuel cost is EPA's estimate at 15,000 miles a year. A 5-mpg difference on an SUV you keep five years is real money: often $1,500-$3,000 over that period.
Hybrids change the math
Where a hybrid version exists (RAV4 Hybrid, Highlander Hybrid and others), it usually beats every gas SUV here on fuel — see our used hybrids ranked. On the used market you get that efficiency without the new-car hybrid premium.
Methodology & sources
Figures are official EPA estimates from fueleconomy.gov: combined MPG (or MPGe for electric), estimated annual fuel cost (EPA's 15,000-mile/year assumption at recent national fuel prices), and EPA driving range for EVs. Where a model offers several drivetrains we show the model average, so treat these as at-a-glance comparisons, not a substitute for the exact trim's window sticker. Data snapshot July 2026.

Fuel economy is only half of ownership cost. Before you buy, also check the car's recall record and run its VIN with Carchieve for open recalls, owner complaints and safety ratings.

Frequently asked questions
What is the most fuel-efficient used SUV?
Among popular used models, the 2020 Toyota RAV4 tops EPA combined fuel economy at 30 mpg, costing roughly $2,100 a year to fuel. Hybrid SUV versions do even better where available.
Are hybrid SUVs worth it on the used market?
Often yes: a hybrid compact SUV can use 30-40% less fuel than its gas twin, and on the used market you skip the new-car hybrid price premium. Weigh the fuel saving against battery age and any price difference.
Does a higher-MPG SUV mean lower running costs overall?
Fuel is a big part but not all of it. A thirstier SUV with a clean recall record and cheap parts can still be cheaper to own than an efficient one with expensive repairs — check the recall and complaint history too.
