The Cheapest, Most Fuel‑Efficient Car: What to Buy Right Now

For most U.S. shoppers today, the least expensive new car that also delivers truly outstanding fuel economy is the Toyota Corolla Hybrid LE, typically priced around $23,000–$24,000 and returning roughly 50–53 mpg combined. If your absolute priority is the lowest sticker price, the Mitsubishi Mirage is cheaper (about $17,000–$18,000) but less efficient at around 39 mpg combined, while the Toyota Prius remains the fuel‑economy champion at up to 57 mpg combined, though it costs more (about $28,000+). Below is a deeper look at how these choices compare, what “cheapest” can mean in practice, and the best alternatives depending on how and where you drive.

How “cheapest” and “most fuel‑efficient” are defined

Cheapest can refer to the lowest purchase price or the lowest total cost to own (fuel, maintenance, insurance, depreciation). Most fuel‑efficient typically means the highest EPA combined mpg for gasoline vehicles; for plug‑in hybrids and EVs, fuel use can drop dramatically if you regularly charge at home. Because many buyers prioritize a low up‑front price and low gas bills, this guide focuses on gasoline and hybrid models that balance both.

Top picks among new cars (U.S., 2024–2025 model years)

The following models represent the best balance of up‑front price and fuel efficiency, based on current EPA ratings and typical transaction prices as of late 2024/early 2025. Exact pricing varies by region, incentives, and trim.

• Toyota Corolla Hybrid LE
  – Approx. price: $23,000–$24,000
  – EPA: about 50–53 mpg combined (FWD)
  – Why it stands out: It’s the least expensive way to get 50‑plus mpg in a new car, with Toyota’s strong reliability and broad dealer network.
• Mitsubishi Mirage (CVT)
  – Approx. price: $17,000–$18,000
  – EPA: about 39 mpg combined (≈36 city/43 hwy)
  – Why it stands out: The lowest new‑car price in the U.S.; fuel economy is good for a non‑hybrid, though performance and refinement are modest. (Mitsubishi has signaled the Mirage will exit the U.S. after the 2025 model year.)
• Toyota Prius LE (FWD)
  – Approx. price: $28,000–$30,000
  – EPA: up to 57 mpg combined
  – Why it stands out: The mpg leader among non‑plug‑in cars. Higher upfront cost than the Corolla Hybrid, but lower fuel use.
• Hyundai Elantra Hybrid Blue
  – Approx. price: $25,000–$26,000
  – EPA: about 54 mpg combined
  – Why it stands out: Excellent efficiency at a mid‑$20k price, often undercutting the Prius while exceeding the Corolla Hybrid’s mpg.
• Kia Niro Hybrid
  – Approx. price: $28,000–$31,000
  – EPA: about 53 mpg combined
  – Why it stands out: SUV‑like space and strong mpg; costs more than compact sedans but offers extra practicality.

In short, if you want the best combination of low price and high mpg, the Corolla Hybrid LE is the value benchmark; if you want the absolute highest mpg, the Prius leads; and if you want the lowest new‑car price regardless of mpg, the Mirage is hard to beat.

What if you can plug in?

Plug‑in hybrids (PHEVs) can be the cheapest to “fuel” if you charge regularly, since many daily trips can be done on electricity alone. After the battery is depleted, they still operate like efficient hybrids on gasoline.

• Toyota Prius Prime
  – Approx. price: $32,000–$36,000
  – Electric range: up to about 44 miles; gas‑only: roughly 50–52 mpg
  – Why it stands out: Commute on electricity, take road trips at class‑leading efficiency.
• Kia Niro PHEV
  – Approx. price: $34,000–$37,000
  – Electric range: about 33–34 miles; gas‑only: around high‑40s mpg
  – Why it stands out: Practical size with meaningful EV range at a still‑accessible price.

If you can charge at home and most trips are short, a PHEV often yields the lowest day‑to‑day cost while preserving long‑range flexibility.

Real‑world fuel costs: what you’ll actually spend

Using a simple estimate of 15,000 miles per year and gasoline at about $3.75 per gallon, here’s what annual fuel spend looks like across the leading options. Your costs will vary with fuel prices and driving style.

• Prius (57 mpg): roughly $990/year (15,000 ÷ 57 × $3.75)
• Elantra Hybrid (54 mpg): roughly $1,040/year
• Corolla Hybrid (≈50–53 mpg): roughly $1,060–$1,125/year
• Niro Hybrid (≈53 mpg): roughly $1,060/year
• Mirage (≈39 mpg): roughly $1,440/year

These estimates show how quickly higher mpg pays back: compared with the Mirage, a 50‑plus‑mpg hybrid can save about $300–$400 per year at typical U.S. fuel prices.

Best used‑car buys if you want cheap and ultra‑efficient

Buying used can dramatically lower the purchase price while keeping fuel costs minimal. The following models are standouts for value and mpg on the used market.

• Hyundai Ioniq Hybrid (2017–2022)
  – EPA: up to 58–59 mpg combined in Blue trim
  – Why it’s great used: Often the least‑expensive way to get near‑Prius mpg.
• Toyota Prius (2016–2022)
  – EPA: typically 50–56 mpg combined depending on year/trim
  – Why it’s great used: Proven reliability and widespread availability.
• Toyota Corolla Hybrid (2020–2023)
  – EPA: about 50–52 mpg combined
  – Why it’s great used: Strong mpg with Toyota durability at lower prices than new.

With used hybrids, prioritize vehicles with documented maintenance, a recent hybrid battery health check if available, and up‑to‑date recalls or service campaigns.

When “cheapest” changes based on your situation

Your driving pattern, location, and incentives can change the best choice. Consider the following factors when deciding what’s truly cheapest for you.

1. High annual mileage (20,000+): Higher‑mpg hybrids (or a PHEV you can charge) usually beat the lowest‑price non‑hybrid on total cost after a couple of years.
2. Short urban commutes with home charging: A PHEV can slash fuel spending since many trips use electricity only.
3. Cold climates or hilly terrain: Expect lower real‑world mpg; choose a model whose efficiency margin still meets your needs.
4. Resale values: Toyotas and some Hyundais/Kias hold value well, improving total cost of ownership versus cheaper cars with steeper depreciation.
5. Incentives and fees: State or utility rebates (often for PHEVs/EVs), local taxes, and dealer markups can tilt the math.

Weighing these variables alongside sticker price will help you find the truly least‑cost option over the years you plan to own the car.

How to maximize fuel economy and minimize ownership costs

Regardless of the car you choose, the following habits and choices can improve mpg and lower total expenses.

• Keep tires properly inflated and aligned; underinflation can cut mpg noticeably.
• Avoid excess idling and aggressive acceleration; smooth driving saves fuel.
• Use Eco drive modes and precondition the cabin while plugged in (for PHEVs).
• Plan maintenance on schedule; clean air filters and fresh oil help efficiency.
• Shop insurance and consider higher deductibles if appropriate to reduce premiums.

Small improvements add up, especially over high annual mileage, further narrowing the gap between models.

Bottom line

If you want the cheapest new car that’s also genuinely fuel‑efficient, the Toyota Corolla Hybrid LE is the standout, delivering 50‑plus mpg at a mid‑$20k price. If you need the lowest possible purchase price, the Mitsubishi Mirage is the bargain champ—just budget for higher fuel costs than a hybrid. And if maximizing mpg is the goal, the Toyota Prius leads, with the Hyundai Elantra Hybrid offering a strong, slightly cheaper alternative. Plug‑in hybrids can be the lowest‑cost choice to “fuel” if you can charge regularly. Your best pick depends on how you drive, how long you’ll keep the car, and what incentives are available where you live.

What car gets 50 MPG?

Several vehicles, primarily hybrids, achieve 50 mpg or more, including the Toyota Prius (up to 57 mpg combined), Hyundai Elantra Hybrid (up to 54 mpg combined), Toyota Camry Hybrid (around 51-52 mpg combined), and the Toyota Corolla Hybrid (around 50-53 mpg combined), depending on the model year and specific trim. The Honda Civic Hybrid is also a contender, with models getting close to 50 mpg combined.
 
Here are a few models known for achieving 50 mpg or more:

Which car gets 70 MPG?

Cars achieving around 70 mpg are primarily plug-in hybrids (PHEVs) or highly efficient hybrid vehicles, with models like the Toyota Prius Prime, Hyundai Ioniq, and Kia Niro being good examples that can reach or exceed this figure under ideal conditions. While some specific models, like the Toyota Prius itself or even some self-charging hybrids, may offer mileage close to 70 mpg, achieving 70 mpg is considered excellent and often requires specific driving habits and conditions, particularly for plug-in hybrids that rely on electric power for some of their range. 
Examples of Cars That Can Reach 70 MPG or Higher

• Toyota Prius Prime: Opens in new tabAs a plug-in hybrid, it can achieve very high MPG when utilizing its electric-only range and then transition to a hybrid mode, getting close to 70 mpg on longer journeys. 
• Hyundai Ioniq: Opens in new tabThis hybrid is known for being a budget-friendly option and can offer more than 70 mpg with gentle driving. 
• Kia Niro: Opens in new tabThe Kia Niro is another hybrid that provides excellent fuel efficiency, making it a strong contender in this category. 
• Toyota Prius (Self-Charging): Opens in new tabWhile not achieving the 70 mpg of the Prime, the standard, self-charging Prius offers excellent mileage that can approach or be in the high 50s MPG range. 

Why 70 MPG is Difficult

• Electric-Only Range: Many cars that get this high of an MPG figure are often plug-in hybrids (PHEVs) that can run on electric power for shorter distances, which helps them achieve such high combined ratings. 
• Ideal Conditions: Hitting these numbers often depends on factors like driving style (gentle acceleration and braking), driving conditions (city vs. highway), and consistent maintenance. 
• No “Golden Number”: There isn’t a single, fixed number for achieving 70 mpg, as it varies based on the specific model and how it’s driven. 

How to Achieve High MPG

• Drive Gently: Smooth acceleration and gradual braking improve fuel efficiency. 
• Drive in Ideal Conditions: Driving at consistent speeds on the highway, for example, can improve MPG compared to stop-and-go city driving. 
• Consider PHEVs and Hybrids: These types of vehicles are designed to maximize fuel economy and are your best bet for finding a 70 mpg car.
