Most SUVs average roughly 25–30 MPG, but size and powertrain make a substantial difference.
The EPA’s 2025 Automotive Trends Report puts model-year 2024 averages at 30.2 MPG for car-classified SUVs and 24.7 MPG for truck-classified SUVs, excluding electric vehicles and plug-in hybrids.
These figures, which still include conventional hybrids, offer a more useful benchmark than averages inflated by electric vehicles. For buyers, the distinction between SUV categories matters more than a single industry-wide MPG figure.
Average SUV Gas Mileage: What the EPA Data Shows
| EPA Vehicle Category | Average MPG | Excluding EVs and Plug-In Hybrids |
|---|---|---|
| Car-classified SUVs | 39.2 | 30.2 |
| Truck-classified SUVs | 25.7 | 24.7 |
The EPA’s car-SUV and truck-SUV categories are regulatory classifications, not simply compact versus full-size SUVs. Its figures are also production-weighted averages for new vehicles, not every SUV currently on American roads.
That’s why no single MPG figure represents all SUVs accurately. Compare fuel economy within the vehicle class and powertrain you’re actually considering.
What Is Considered Good Gas Mileage for an SUV?
For practical shopping purposes, I would use the following approximate benchmarks.
| SUV Type | Reasonable Combined MPG Target |
|---|---|
| Small gasoline crossover | 28–32 MPG |
| Compact hybrid SUV | 35–45 MPG |
| Midsize gasoline SUV | 23–28 MPG |
| Midsize hybrid SUV | 32–38 MPG |
| Large gasoline SUV | 17–23 MPG |
These MPG ranges are shopping benchmarks, not EPA averages. AWD, larger wheels, performance engines, and off-road equipment can reduce efficiency.
A compact SUV returning 30 MPG is reasonably efficient, while a three-row hybrid achieving 35 MPG is particularly impressive. Compare SUVs with similar space and capability—not simply the highest MPG on the market.
Why SUV Size Doesn’t Tell the Whole Story
Weight matters most during acceleration, while aerodynamic drag becomes increasingly important at highway speeds. An SUV’s large frontal area and upright shape require substantially more power at 75 MPH than at 55 MPH, even with an efficient engine.
Hybrids counter some of these losses by recovering braking energy and improving engine efficiency, particularly in city driving. Turbocharged engines can also save fuel under moderate loads, but their advantage often shrinks when sustained power demand increases.
The takeaway: SUV fuel economy depends on weight, aerodynamics, driving conditions, and powertrain efficiency—not engine displacement alone.
How Much Does SUV Gas Mileage Actually Cost?
The difference between 20 and 30 MPG might appear modest, but its financial impact becomes substantial over several years. Assuming 12,000 miles annually and gasoline at $3.25 per gallon, here’s what different fuel-economy ratings cost.
| Combined MPG | Gallons Per Year | Annual Fuel Cost |
|---|---|---|
| 20 MPG | 600 | $1,950 |
| 25 MPG | 480 | $1,560 |
| 30 MPG | 400 | $1,300 |
| 35 MPG | 343 | $1,114 |
| 40 MPG | 300 | $975 |
At 12,000 miles annually and $3.25 per gallon, improving from 20 to 30 MPG saves $650 per year, or $6,500 over a decade. But moving from 35 to 40 MPG saves just $139 annually.
That’s because each additional MPG delivers progressively smaller fuel savings as efficiency increases.
The takeaway: Don’t pay a large purchase-price premium for a small MPG improvement. Compare the actual annual fuel savings against the extra cost of the vehicle.
Does Buying a Hybrid SUV Always Save Money?
Not necessarily. At 12,000 miles annually and $3.25 per gallon, upgrading from a 30-MPG gasoline SUV to a 40-MPG hybrid saves approximately $325 per year.
A $1,500 hybrid premium takes 4.6 years to recover through fuel savings, while a $5,000 premium takes more than 15 years. Financing, maintenance, and resale value can change the calculation.
The takeaway: Higher MPG doesn’t automatically mean better value. Compare the purchase-price premium against realistic fuel savings.

Why Your Real-World MPG May Differ From EPA Estimates
EPA ratings provide standardized comparisons, but speed, temperature, terrain, short trips, and vehicle loading can significantly affect real-world MPG. AWD and larger wheels may also reduce efficiency, while hybrid savings vary with driving conditions.
Always compare the exact engine, drivetrain, and trim, not the model’s highest advertised MPG. For electric SUVs, MPGe measures energy efficiency—not gasoline consumption. It shouldn’t be used directly to calculate fuel costs.
What MPG Should You Aim For?
I’d consider 30 MPG combined a good target for a conventional compact SUV, while the high 20s are respectable for a midsize family SUV. A hybrid exceeding 35 MPG can offer substantial savings.
Full-size SUVs serve different needs, so comparing them directly with compact crossovers is misleading. More importantly, choosing the smallest SUV that comfortably meets your needs often saves more than buying an efficient version of an unnecessarily large vehicle.

Final Verdict
EPA data places new conventional and non-plug-in-hybrid SUVs at approximately 24.7–30.2 MPG, depending on regulatory classification. But these averages don’t represent every SUV.
For buyers, compare the exact configuration with similarly capable vehicles, then calculate whether better fuel economy justifies any additional purchase cost.
Ultimately, the most economical SUV isn’t necessarily the one with the highest MPG. It’s the smallest vehicle that meets your needs while delivering the best balance of purchase price, fuel efficiency, and long-term ownership costs.
