Gas Mileage Comparison Calculator

Where the numbers come from

Every vehicle in the picker carries its real EPA combined rating from fueleconomy.gov's full vehicle database, the same federal test data behind the window sticker. One nameplate is many configurations (a Ford F-150 is ten separate EPA entries from a 12 mpg supercharged Raptor R to a 21 mpg two-wheel-drive), so we use the middle of EPA's list for the newest model year and show you the span. Prices default to the AAA national average for regular and the EIA home electricity average, the same figures our fuel cost calculator and EV savings calculator run on, and every one of them is editable.

The worked example, and the framing that started this page

What a year of driving costs, every vehicle in the picker

12,000 miles at $4.15 regular and 18 cents per kWh, cheapest first. EPA combined ratings, median configuration of the newest model year; EVs priced at home charging.

Four things the table says out loud

The spread is 5.2x for the same year of driving. A Tesla Model Y charged at home covers 12,000 miles for $563.76; a full-size gas pickup covers the same miles for $2,929.41. Nothing about the driving changed, only the machine.

The hybrid column is where the everyday money is. Same nameplate, same showroom, different powertrain: the CR-V hybrid saves $342.19 a year over the gas CR-V, the Tucson hybrid $498.50, the Maverick hybrid $686.71, and the F-150 hybrid $501.90. Against a $1,500 hybrid premium, the CR-V's fuel savings repay it in about 4.4 years at average prices, faster where gas is expensive: enter your own price difference above and the payback drops out of the math.

The hybrid question is disappearing because manufacturers answered it. The Camry has been hybrid-only since 2025 and the RAV4, America's best-selling vehicle that is not a pickup, went hybrid-only for 2026: its EPA table simply has no gas-only entries anymore. That is why this page lists a 2025 gas RAV4 beside the 2026 hybrid: the 41 against 29.5 mpg gap is now a model-year decision, not a trim decision.

Shape still beats fuel. An F-150 Lightning costs 8.6 cents a mile on home electricity while a Prius costs 7.8 cents on gasoline: an electric full-size truck is out-thrifted by a hybrid hatchback, because pushing a brick through the air is expensive no matter what pushes it. The Model Y, at 4.7 cents, beats them both, and even the minivans tell the story: the hybrid Sienna undercuts the gas Odyssey by $860.82 a year doing the same school runs.

EPA numbers versus your numbers

The EPA combined rating is a controlled test, and real-world driving typically lands a little under it (the EPA's own fleet-wide real-world estimate runs about 27 mpg against higher sticker figures). But the shortfall hits both sides of a comparison roughly alike, so the gap between two vehicles is sturdier than either absolute number. To measure what your actual car actually does, fill up, drive, fill up again, and run the MPG calculator; to see what a specific trip costs, the fuel cost calculator owns that question. And fuel is only one line of what a vehicle costs: depreciation is usually bigger, which is the total cost of ownership calculator's whole argument.

What is deliberately not here

Plug-in hybrids are excluded on purpose. A PHEV's real cost depends almost entirely on how often it is charged: a Prius Prime driven 30 miles a day and plugged in nightly burns almost no gas, and the same car never plugged in is just a heavy hybrid. One number would be dishonest, so we leave PHEVs to their own arithmetic. EV charging is priced at home rates, where most charging happens; road-trip charging at DC fast rates near 47 cents per kWh roughly triples the electric cost per mile, which our EV charging cost calculator prices in detail. And trim-level differences within a nameplate are real (that is the span we print), so if you know your exact configuration's rating, the custom MPG option takes it.
