If you’re hunting for the best used cars with the best MPG, you’re really asking two questions: which cars sip the least fuel, and which ones actually save you money once you factor in reliability, maintenance, and how you drive. In 2025 that means looking beyond just tiny gas sedans and including hybrids and used EVs in the mix.
MPG isn’t everything
Two cars with the same MPG can have very different ownership costs. Hybrids usually cut fuel spend the most, but a well-priced used EV with healthy battery can beat them both, especially if you can charge at home.
Why MPG Still Matters in 2025
New federal rules are pushing average real‑world mileage for new vehicles toward about 38 mpg by 2031, but the used market is a mixed bag. That means you can still stumble into a 20‑mpg crossover, or you can deliberately target 35–55 mpg+ used cars and lock in much lower running costs over the next decade.
What High MPG Actually Saves You
Think in total cost, not just MPG
When you compare cars, run a 5‑year fuel cost estimate alongside insurance, maintenance, and taxes. A slightly more expensive hybrid or EV often wins once you do the math.
MPG vs MPGe: How to Compare Gas, Hybrid, and EVs
MPG: Gas and traditional hybrids
MPG (miles per gallon) tells you how far a car goes on one gallon of gasoline. For used gas and regular hybrids:
- 30–35 mpg combined = decent
- 36–45 mpg = very good
- 46–55+ mpg = top‑tier hybrids
Hybrids like the Toyota Prius or Hyundai Ioniq routinely hit 50+ mpg combined in real‑world driving when driven smoothly.
MPGe: EVs and plug‑in hybrids
MPGe converts electricity use into an MPG‑equivalent so you can compare it with gas cars. Efficient EVs like the Hyundai Ioniq Electric or BMW i3 are rated around 110–135 MPGe, making even a 50‑mpg hybrid look thirsty on energy per mile.
The catch: you must consider electricity rates, charging access, and battery health. That’s exactly what Recharged’s Score Report and battery diagnostics are built to unpack for used EVs.
Don’t compare MPGe directly to MPG on cost
MPGe is an efficiency measure, not a direct fuel‑cost comparison. Electricity prices vary widely. Use a fuel‑cost calculator (kWh per 100 miles × your kWh price) to compare an EV’s cost per mile to gas at your local pump price.
Best Used Gas Cars With Great MPG
If you want something simple, no high‑voltage battery, no charging, these are the standout used gas cars with excellent mileage. They won’t touch a Prius on paper, but they’re cheap to run and often cheaper to buy.
Top Used Gas-Only MPG Champs
Great if you want low complexity and affordable pricing
Mitsubishi Mirage
EPA: ≈39 mpg combined (recent model years)
Why it’s good: One of the thriftiest gas cars sold in the U.S., and usually very affordable on the used market.
Best for: City commuters who prioritize low cost over speed or refinement.
Honda Civic (non-hybrid)
EPA: Up to ~36 mpg combined in newer generations.
Why it’s good: Excellent reliability, strong resale, and real‑world highway economy in the low 40s when driven gently.
Best for: Drivers who want efficiency without giving up comfort or refinement.
Hyundai Elantra / Toyota Corolla
EPA: Around 35–36 mpg combined in efficient trims.
Why they’re good: Mainstream compact sedans with low ownership costs, good safety tech, and no hybrid complexity.
Best for: First‑time buyers and budget‑minded families.
Watch for “eco” trims with trade‑offs
Some ultra‑efficient gas models use skinny low‑rolling‑resistance tires and tall gearing. Great for MPG, but they can feel sluggish and may have higher tire replacement costs if sizes are unusual.
Best Used Hybrids for Top MPG
If your goal is strictly “fewest gallons burned,” used hybrids are where things get interesting. Modern hybrids routinely deliver 45–55 mpg combined, and many have long track records for reliability.
High-MPG Used Hybrids Worth Targeting
These models combine strong efficiency with solid long-term reliability
Toyota Prius (2010–2022)
Typical EPA: 46–56 mpg combined depending on generation and trim.
Why it’s a star: The Prius is the default answer for anyone asking about the best used cars with the best MPG. Older models from the early 2010s still deliver high 40s mpg if maintained; newer cars add better safety tech and more power.
Buyer notes: Prioritize maintenance records and avoid cars with unknown accident history. High‑mileage Priuses can still be good buys if the hybrid battery is healthy.
Hyundai Ioniq Hybrid (2017–2022)
Typical EPA: Around 55 mpg combined in many trims.
Why it’s a star: It essentially matches or beats the Prius on fuel economy with a more conventional driving feel and often slightly lower used prices.
Buyer notes: Look for cars with completed recalls and up‑to‑date software; many still have partial warranty coverage on the hybrid system.
Honda Civic & Accord Hybrid
Typical EPA: Roughly 48–54 mpg combined depending on model and year.
Why they’re great: They look and drive like normal sedans but deliver hybrid‑level economy. Mid‑size Accord Hybrid in particular gives you space, comfort, and 45–50 mpg easily.
Buyer notes: Focus on 2018+ for Accord Hybrid and recent‑generation Civic Hybrids for the best safety tech and refinement.
Toyota Camry Hybrid, Corolla Hybrid, Kia Niro
Typical EPA: 47–53 mpg combined for many trims.
Why they’re great: Camry Hybrid offers mid‑size comfort; Corolla Hybrid is a straightforward compact; Kia Niro Hybrid adds small‑SUV practicality with ~50 mpg.
Buyer notes: Check for fleet history on Niro and Corolla used cars, and favor one‑owner vehicles when possible.
Why hybrids are the sweet spot for most buyers
If you can’t reliably charge at home or work, a used hybrid is usually the best blend of efficiency, simplicity, and nationwide refueling flexibility. You’ll get EV‑like MPG with gas‑station convenience.
High-Efficiency Used EVs and Plug-In Hybrids
Visitors also read...
If you’re open to going electric, some used EVs deliver the equivalent of 100–130 MPGe. In plain language, they use only a third or a quarter of the energy per mile compared with a typical gas SUV. The trade‑offs are range, charging access, and battery health.
Efficient Used EVs & PHEVs to Consider
Great for short commutes and drivers who can charge regularly
Hyundai Ioniq Electric / Kona Electric
Why they matter: Among the most efficient EVs sold, with MPGe ratings well north of 100 and realistic ranges suitable for daily commuting.
Best for: Suburban or urban drivers with home charging who want to slash fuel spend to pennies per mile.
BMW i3 (BEV or REx)
Why it matters: A compact premium EV with very high efficiency. Range‑extender (REx) versions add a small gas generator for backup on longer trips.
Best for: City dwellers and second‑car households that want EV efficiency with occasional long‑trip flexibility.
Plug‑in hybrids (Prius Prime, Volt, etc.)
Why they matter: PHEVs like the Prius Prime or Chevy Volt can cover many commutes on electricity alone but still run as efficient hybrids on longer trips.
Best for: Mixed‑usage drivers who can charge at home but regularly drive beyond pure‑EV range.
Battery health is the make-or-break factor
An older EV with a heavily degraded battery can lose range faster than numbers on a spec sheet suggest. With Recharged’s Score Report, every used EV comes with verified battery health so you can see real range and degradation before you buy.

Checklist: How to Shop for a High-MPG Used Car
Practical Steps Before You Buy
1. Define your real driving pattern
Track a typical week: miles per day, highway vs city, and how often you take 200+ mile trips. This determines whether a gas car, hybrid, or EV actually fits your life.
2. Decide if you can reliably charge
If you have a driveway or garage, installing Level 2 charging makes a used EV or plug‑in hybrid incredibly compelling. If you rely on street parking, prioritize hybrids over full EVs.
3. Set a total-cost-of-ownership budget
Look beyond purchase price. Estimate 5‑year fuel, maintenance, insurance, and potential battery or hybrid‑system repairs. A slightly pricier hybrid can still be cheaper overall than a thirsty SUV.
4. Target specific high-MPG models
Shop with a short list, Prius, Ioniq Hybrid, Corolla Hybrid, Civic/Accord Hybrid, Niro, or efficient gas compacts, instead of browsing everything. This keeps you out of low‑MPG traps.
5. Check history and condition carefully
Run a history report, look for consistent maintenance, and avoid cars with flood or severe accident history. For hybrids and EVs, prioritize vehicles with documented service at a dealer or specialist.
6. For EVs, demand real battery data
Don’t accept vague statements like “range seems fine.” At Recharged, every EV comes with a <strong>Recharged Score</strong> and battery health diagnostics so you can see remaining capacity, estimated range, and cell health before you buy.
Use a simple rule-of-thumb short list
If you don’t want to overthink it, you generally can’t go wrong aiming for: Prius or Ioniq Hybrid for maximum MPG, Corolla/Civic for simple gas economy, or Kona/Ioniq Electric if you can charge at home.
When a Used EV Beats a High-MPG Gas Car
It’s tempting to assume a 50‑mpg hybrid is always the cheapest path, but used EVs can be stealth bargains, especially if you have predictable commuting and access to home charging.
Used EV wins when…
- You drive mostly under 100–150 miles per day.
- You can charge at home or at work most nights.
- Your local electricity rate is reasonable, and you avoid the priciest public DC fast chargers for daily use.
- You value low maintenance: no oil changes, fewer moving parts, and less brake wear.
In these cases, a used EV’s cost per mile can easily undercut even the most efficient hybrid.
Hybrid or gas wins when…
- You regularly road trip or live far from charging infrastructure.
- You rely on street parking with no consistent home charging.
- Local public charging is expensive or unreliable.
- You want a single vehicle to handle both daily use and spontaneous long trips with zero planning.
Here, a high‑MPG hybrid, or a very efficient gas compact, often makes more sense.

FAQ: Best Used Cars With the Best MPG
Common Questions About High-MPG Used Cars
Bottom Line: Choose the Right Efficiency for You
There’s no single “best used car with the best MPG” for everyone. For some buyers it’s a Prius or Ioniq Hybrid quietly returning 50 mpg for years. For others it’s a simple Civic or Corolla that just works and still hits the mid‑30s. And for drivers with home charging, a used EV or plug‑in hybrid can cut energy use so dramatically that MPG almost stops mattering.
Start with your daily miles, charging reality, and budget, then build a short list of efficient models that fit that life, rather than chasing a single MPG number. If you’re curious whether a used EV or plug‑in might actually beat your high‑MPG gas options, explore Recharged’s inventory, where every vehicle includes a transparent Recharged Score Report, verified battery health, and expert guidance from first click to delivery.
