What Is Good Gas Mileage?

Real EPA benchmarks by vehicle class, and the surprising 2024 data point that just flipped the old “SUVs are worse than sedans” assumption. US & Canada, 2026.

“Good gas mileage” only means something relative to a vehicle’s own class. 28 MPG is disappointing for a compact sedan and excellent for a full-size pickup. This page uses the EPA’s own official benchmarks, by class, so you can judge your vehicle against the right comparison instead of a single number pulled out of the air.

Quick Answer

The EPA’s own tracked average for all new model year 2024 vehicles sold in the US was 27.2 MPG real-world, a record high, though that figure is boosted by electric and plug-in hybrid vehicles; without them the average is closer to 25.5 MPG. As a rough class benchmark: 30+ MPG is good for a sedan or car-based SUV, 23-26 MPG is good for a truck-based SUV, 20+ MPG is good for a pickup, and 40+ MPG is good for a hybrid of any body style.

The number that surprises most people: in the EPA’s own 2024 data, car-based SUVs pulled ahead of traditional sedans in average fuel economy for the first time, purely because of how many of them are now electric or plug-in hybrid. See the section below for why that flips a long-standing assumption.

The Mechanism Most Guides Skip

SUVs Just Overtook Sedans in the Official Data

“Sedans get better gas mileage than SUVs” has been safe conventional wisdom for decades, and most “good MPG” articles still repeat it as a settled fact. The EPA’s own model year 2024 Automotive Trends Report shows it’s no longer reliably true. Car-based SUVs increased their average fuel economy by 7.2 MPG in a single model year, enough to make them the vehicle type with the highest average fuel economy of all five categories the EPA tracks, ahead of sedan/wagons.

The reason isn’t that gasoline SUVs suddenly got dramatically more efficient. It’s electrification mix. About 30% of car SUVs sold in model year 2024 were battery-electric, with another 3% plug-in hybrid, a far higher electrified share than sedans saw that year. Because electric and plug-in models post very high MPGe figures, they pull the whole category’s average up sharply. A gasoline-only SUV still generally burns more fuel than a comparably sized gasoline sedan, the underlying physics of a heavier, less aerodynamic body hasn’t changed.

The honest takeaway: a class average is only as meaningful as what’s mixed into it. If you’re comparing two specific gasoline vehicles, compare their individual EPA ratings, not a class average that might be skewed by EVs in that class. If you’re comparing overall categories fleet-wide, know that “SUV” no longer automatically means “worse than sedan,” it depends entirely on the specific vehicle’s powertrain.

The Real Benchmarks

Good Gas Mileage by Vehicle Class

For context on the whole fleet: the EPA’s tracked average new-vehicle real-world fuel economy climbed from 21.0 MPG in 1984 to 27.2 MPG in model year 2024, a roughly 30% gain over four decades, even as the market shifted heavily toward larger, less inherently efficient vehicle types. Truck-type vehicles (SUVs, pickups, and minivans combined) now make up about two-thirds of new vehicle production, up from under a fifth in 1975, so today’s fleet average reflects a much less car-heavy mix than it used to.

Setting Realistic Expectations

Why Your Dashboard Number Won’t Match the Window Sticker

If your own vehicle isn’t hitting the EPA-rated number on the window sticker, that alone doesn’t mean something’s wrong. EPA window sticker ratings come from controlled laboratory testing under specific conditions, and real-world driving, cold starts, hills, traffic, wind, and individual driving style, typically brings actual mileage in somewhere around 10-20% below the rated figure. That gap is expected, not a sign of a problem.

Where it’s worth paying attention is a gap that’s larger than that, or one that’s gotten noticeably worse over time on the same vehicle and driving pattern. That’s the signal to work through our ranked gas mileage checklist, starting with the items that matter most, rather than assuming your car is simply “bad on gas.”
