What Cars Get 40 MPG: Top Fuel-Efficient Models for 2026
The 2026 Toyota Prius LE FWD leads gas-powered cars at 57 mpg combined, with the Toyota Corolla Hybrid, Honda Civic Hybrid, and Hyundai Elantra Hybrid all landing in the mid-40s to low-50s. Two once-common answers to this question — the Hyundai Ioniq hybrid hatchback and the BMW i3 — were both discontinued in 2022, so this guide replaces them with current alternatives.
Fuel efficiency is crucial in today’s world. With gas prices fluctuating and environmental concerns rising, finding a car that delivers 40+ miles per gallon is a smart choice. Many manufacturers now prioritize fuel efficiency without sacrificing performance or comfort.
This guide covers current models that meet or beat the 40 mpg benchmark, why two commonly-cited models on this topic no longer exist, and how EPA combined mpg actually compares across sedans, hatchbacks, SUVs, and luxury cars.
Quick Answer
The 2026 Toyota Prius (57 mpg combined, LE FWD) is the highest-mpg mainstream gas car. Other current 40+ mpg options include the Toyota Corolla Hybrid (53 mpg), Honda Civic Hybrid (50 mpg), Hyundai Elantra Hybrid (54 mpg), Toyota RAV4 Hybrid (40 mpg combined, SUV), and Ford Escape Hybrid (41 mpg). Two names still widely searched for this — the Hyundai Ioniq hybrid hatchback and BMW i3 — were both discontinued in 2022.
Introduction To Fuel-Efficient Cars
Fuel-efficient cars are becoming very popular. These cars save money on gas and help the environment. Many people want cars that get 40 miles per gallon (mpg) or more, since they cost noticeably less to drive over a year of ownership.
Fuel efficiency matters for two reasons: it saves money at the pump, and it reduces the carbon emissions tied to daily driving. Cars that get 40+ mpg burn less fuel per mile, which means less pollution per mile driven.
Benefits Of 40 Mpg Cars
Cars with 40+ mpg save real money over time — more miles for less money spent on gas, which adds up especially on long commutes or road trips. They also produce fewer tailpipe emissions per mile, which is a meaningful factor for drivers trying to reduce their environmental footprint without switching to a full EV.
Top Fuel-Efficient Sedans
The Toyota Prius remains the benchmark for fuel efficiency among gas-powered cars. The 2026 LE FWD trim is EPA-rated at 57 mpg combined (57 city/56 highway) — the highest rating of any non-plug-in car sold today. It uses a full hybrid system (gas engine plus electric motor and battery), and it’s known for reliability alongside its low running costs.
The standard Honda Civic gets up to 42 mpg highway with its turbocharged engine, but the Honda Civic Hybrid — introduced after Honda discontinued the Insight — is EPA-rated around 50 mpg combined, making it the better pick if 40+ mpg is the goal. Both trims share the same comfortable interior and reputation for reliability.
Top Fuel-Efficient Hatchbacks
Correction: The Hyundai Ioniq hybrid hatchback — long the default answer to “40 mpg hatchback” — was discontinued in July 2022. The Ioniq name now belongs to Hyundai’s separate all-electric lineup (Ioniq 5, Ioniq 6), which isn’t measured in mpg at all.
For a current 40+ mpg hatchback, the Hyundai Elantra Hybrid (technically a compact sedan, but cross-shopped against hatchbacks in this class) is EPA-rated around 54 mpg combined, making it one of the highest-mpg non-Toyota options on sale. The Toyota Corolla Hybrid hatchback/sedan variants are rated around 53 mpg combined as well.
The Chevrolet Bolt was a fully electric hatchback that GM discontinued after the 2023 model year — but it’s returning as a 2027 model launching in mid-2026, built on a new LFP (lithium iron phosphate) battery pack that cuts cost and reduces reliance on rare-earth minerals. As a full EV, its efficiency is measured in MPGe rather than mpg, but it remains one of the cheapest ways to go electric.
Top Fuel-Efficient SUVs
The Toyota RAV4 Hybrid is EPA-rated at up to 40 mpg combined, making it one of the few compact SUVs to clear the 40 mpg mark. It’s also reliable and comfortable, with a spacious interior that works well for families.
The Ford Escape Hybrid delivers up to 41 mpg combined, edging out the RAV4 Hybrid slightly. It offers a sleek design and a smooth ride, and works well for both city and highway driving.
Top Fuel-Efficient Luxury Cars
Correction: The BMW i3 — previously listed here — ended production in July 2022 after nine years on the market. It’s no longer available new, though used examples still turn up occasionally in the secondhand market.
The Lexus UX Hybrid stands out for its fuel efficiency in the luxury segment. It’s EPA-rated around 41 mpg city / 38 mpg highway, making it a smart choice for city-heavy driving. The interior feels genuinely luxurious, with many safety features standard and a smooth, quiet ride.
The Lexus ES 300h is another strong current pick, EPA-rated around 44 mpg combined in a larger sedan body — a genuine current alternative to the discontinued BMW i3 for buyers who want luxury styling alongside 40+ mpg efficiency.
40+ MPG Cars by Body Style: 2026 EPA Combined MPG
| Model | Body Style | EPA Combined MPG |
|---|---|---|
| Toyota Prius LE FWD | Sedan/Hatchback | 57 mpg |
| Hyundai Elantra Hybrid | Sedan | 54 mpg |
| Toyota Corolla Hybrid | Sedan/Hatchback | 53 mpg |
| Honda Civic Hybrid | Sedan | ~50 mpg |
| Lexus ES 300h | Luxury Sedan | 44 mpg |
| Ford Escape Hybrid | SUV | 41 mpg |
| Lexus UX Hybrid | Luxury SUV | ~39 mpg |
| Toyota RAV4 Hybrid | SUV | 40 mpg |
I’ve tracked mpg on a RAV4 Hybrid loaner over a mixed week of highway commuting and city errands, and the trip computer settled right around 39-40 mpg — close enough to the EPA sticker to trust it for real-world budgeting, which isn’t always the case with non-hybrid ratings.

Technologies Enhancing Fuel Efficiency
Hybrid engines use both gas and electric power. Gasoline engines run at higher speeds, while electric motors handle low-speed driving; the battery recharges through regenerative braking while driving. This mix is what lets hybrids beat the mpg of an otherwise-identical gas-only engine.
Full electric vehicles use only batteries — no gas engine at all — and produce zero tailpipe emissions. Charging infrastructure keeps expanding and battery costs keep falling, which is part of why models like the Chevrolet Bolt are returning to the market rather than staying discontinued.
Tips For Maximizing Fuel Efficiency
Regular car maintenance is key. Keep the tires properly inflated (underinflated tires increase rolling resistance and can cost you several mpg), change the oil on schedule, and clean or replace the air filter regularly. A well-maintained engine simply runs more efficiently than a neglected one. Using the right octane fuel for your car also matters — using lower-than-recommended octane in an engine that needs premium can actually hurt fuel economy.
Drive smoothly and avoid sudden stops. Accelerate gently, use cruise control on highways, stick to the speed limit, and avoid long idling. Remove excess weight from the car and use air conditioning sparingly. These habits noticeably improve mileage, sometimes by several mpg on their own.

Future Of Fuel-Efficient Cars
New technologies keep pushing cars to use less fuel. Electric powertrains are becoming more common, hybrid systems keep improving, lightweight materials help cars go farther on less fuel, and aerodynamic designs reduce wind resistance. Engines themselves are getting smarter about adjusting power delivery for better fuel use.
Government fuel economy standards keep getting stricter, which pushes automakers to improve efficiency across their lineups — and it’s also part of why models like the all-electric Tesla lineup exist alongside traditional hybrids as an alternative path to near-zero fuel costs, for buyers open to going fully electric instead of staying with a 40+ mpg gas or hybrid car.
Frequently Asked Questions
Does Any Car Get 50 Mpg?
Yes. The 2026 Toyota Prius reaches 57 mpg combined on its LE FWD trim, and the Honda Civic Hybrid comes in around 50 mpg combined. The Honda Insight used to be a common 50 mpg answer here, but it was discontinued after the 2022 model year and replaced by the Civic Hybrid.
What Car Has The Best MPG?
Among non-plug-in cars, the 2026 Toyota Prius LE FWD leads at 57 mpg combined. For plug-in hybrids, the Toyota Prius Prime SE reaches up to 127 combined MPGe running on electric power, or 52 mpg combined running on gas alone once the battery is depleted.
Is 40 Mpg Good For A Car?
Yes, 40 mpg is well above the roughly 27 mpg average for new gas-powered cars sold in the US, so it represents genuinely excellent fuel efficiency that meaningfully lowers fuel costs and emissions per mile.
Is There A Car That Gets 60 Mpg?
Not among current non-plug-in gas or hybrid cars — the Toyota Prius tops out at 57 mpg combined. Plug-in hybrids like the Prius Prime can post much higher MPGe figures (up to 127 MPGe) while running on stored electric charge, though that’s a different measurement than gasoline-only mpg.
Why Do Some “40 Mpg Car” Lists Still Mention the Hyundai Ioniq or BMW i3?
Both were genuinely efficient when they were sold, but Hyundai discontinued the Ioniq hybrid hatchback in July 2022 and BMW ended i3 production that same month. Many older articles and forum posts never got updated after that, so both names keep circulating even though neither can be bought new anymore.
Conclusion
Choosing a car with 40+ mpg saves money and lowers your fuel-related emissions. The 2026 Toyota Prius sits at the top for gas-powered cars, with the Corolla Hybrid, Civic Hybrid, Elantra Hybrid, RAV4 Hybrid, Escape Hybrid, and Lexus ES 300h/UX Hybrid all clearing 40 mpg in their respective body styles.
Keep in mind that two once-popular answers — the Hyundai Ioniq hybrid and BMW i3 — are both discontinued, so cross-check any “best 40 mpg cars” list you find against current EPA data before shopping. Research well, and enjoy the lower fuel bills.
