With the rising fuel costs and increasing environmental concerns, many car buyers prioritize finding a vehicle with excellent gas mileage.

Higher MPG (miles per gallon) ratings help reduce your carbon footprint and save you money at the pump.

Over the years, numerous fuel-efficient cars have entered the market, and some have even set new standards for fuel economy.

While early hybrid models, such as the Toyota Prius, significantly impacted fuel efficiency, technological advancements have led to further improvements.

Recently, many plug-in hybrid and battery-electric vehicles have also started challenging the traditional internal combustion engine.

This ever-expanding opportunity for green travel means you now have more options than ever when selecting the perfect car with remarkable gas mileage.

Key Takeaways

  • Numerous fuel-efficient cars are available on the market today.
  • Technological advancements have improved gas mileage in all types of vehicles.
  • Choosing the best car for your needs depends on various factors, including fuel efficiency and overall driving experience.

Which Car Has the Best Gas Mileage Ever?

Types of Fuel-Efficient Cars

Hybrid Cars

Hybrid cars combine an internal combustion engine with an electric motor, providing better gas mileage than traditional vehicles.

They’re perfect for those still getting ready for a fully electric experience but still want to save on fuel costs. Examples include midsize and large sedans, as well as some smaller cars. Check out the pros and cons of Hybrid cars.

Plug-in Hybrid Cars

Plug-in hybrid cars take the hybrid concept further by allowing you to charge the battery from an external source.

This means you can drive on electric power alone for short distances, reducing your reliance on gasoline even further. Just remember to monitor your battery levels and plug in when necessary.

Non-Hybrid Cars

Non-hybrid cars also achieve excellent gas mileage due to their efficient internal combustion engines.

More minor, lightweight designs often contribute to better fuel efficiency in these vehicles. If you need more time to embrace electric technology, a fuel-efficient, non-hybrid car might fit you.

Which Model Has the Overall Best Gas Mileage Ever?

Friendly, eh? You’re in for a treat! According to guys over at Carbuzz, the title for the best gas mileage ever goes to the 1985 Suzuki SA310, with a remarkable 42 MPG combined.

Now, let’s dig deeper into that.

The Suzuki SA310 was way ahead of its time regarding fuel efficiency. Known for its lightweight design and compact structure, it achieved numbers.

The secret behind its feat was innovative engineering, including optimized aerodynamics, a three-cylinder engine, and modest horsepower.

While being a champion in gas mileage, the Suzuki SA310 might not have all those fancy bells and whistles you often find in modern cars.

It focused primarily on efficiency and utility, making it a go-to choice back in the 80s for frugal and eco-conscious drivers.

Most Fuel-efficient Cars Of All Time

Toyota Prius

The Toyota Prius has made a name for itself as one of the most fuel-efficient cars ever, with its 2001 model boasting 41 MPG combined.

Over the years, its efficiency has only improved, making it a top choice for those seeking to save on gas costs.

Toyota Corolla Hybrid

Another popular choice for fuel efficiency is the Toyota Corolla Hybrid. Its impressive MPG ratings make it an attractive option for those looking for a compact car with a smaller environmental footprint.

Honda Civic, Hyundai Elantra, and Hyundai Sonata

Honda Civic, Hyundai Elantra, and Hyundai Sonata also deserve mention for their significant fuel efficiency and reliability.

Mitsubishi Mirage and the Kia Rio

Mitsubishi Mirage and the Kia Rio are notable options as well. They offer excellent mileage numbers for their class, making them fantastic choices if you seek a smaller, more wallet-friendly option.

Hybrid vehicles

Hybrid vehicles like the Hyundai Ioniq, Kia Niro, and Honda Insight are worth considering for more eco-conscious consumers.

Other models

Not to be overlooked are the Volkswagen Jetta, Nissan Versa, and Chevrolet Malibu, which continue to prove their worth in fuel economy while offering appealing designs and features.

Additionally, the luxury segment offers fuel-efficient options like Audi A3 and Acura Integra.

Lastly, the Kia Forte, Nissan Altima, and Toyota Camry deliver solid fuel efficiency while maintaining their positions as practical family sedans.

Deciding Factors For Fuel Efficiency

As you evaluate vehicles, look into the fuel efficiency of different car types, including SUVs and models with AWD.

The type of engine plays a significant role in fuel efficiency. Traditional internal combustion engines vary in efficiency, with modern technologies such as turbocharging providing better mileage.

Also, pay attention to the role of transmissions – CVT (continuously variable transmission) offers better fuel economy than manual or automatic transmissions.

Finally, remember that vehicle weight, aerodynamics, and tire type can further impact fuel efficiency.

Car Gas-Mileage History

In the early 1980s, U.S. car manufacturers focused on improving gas mileage. Since then, major automakers like ToyotaHondaHyundaiKiaVolkswagenNissanChevrolet, and Audi have made advancements.

According to cars.com, some top achievers include the 2000 Honda Insight with 49/61/53 MPG city/highway/combined and the 2023 Toyota Prius, which boasts impressive fuel efficiency.

As you consider your next vehicle, remember these automakers’ efforts to improve efficiency and watch for eco-friendly options.

Factors Influencing Gas Prices

Crude oil

One of the primary factors affecting gas prices is the cost of crude oil. Geopolitical events, natural disasters, and global supply and demand fluctuations influence oil prices.

As the price of crude oil changes, so do gas prices at the pump.


Taxes play a significant role in the final price you pay for gasoline. The federal tax on motor gasoline in the U.S. is 18.40 cents per gallon.

Moreover, state taxes and fees also contribute to the total price, averaging 31.67 cents per gallon as of July 1, 2022.

Refining and marketing

Refining, distribution, and marketing costs also contribute to the price of gasoline. The cost of refining gasoline can vary depending on the type of crude oil used and the specific equipment and processes the refinery employs.

Distribution and marketing expenses — such as transporting gasoline from refineries to retail stations and advertising costs — add to the final price you pay for fuel.

It’s crucial to pay attention to EPA ratings. These ratings provide you with an estimate of a vehicle’s fuel efficiency so you can compare different makes and models.

Generally, cars with EPA ratings of 36 mpg or even 33 mpg can save you money on gas compared to those with lower fuel efficiency.

Affordability of Fuel-Efficient Cars

Luckily, some fuel-efficient cars start at a base price of around $20,000. For example, the Toyota Corolla Hybrid offers impressive fuel economy at a reasonable cost.

You can find affordable fuel-efficient options within various price ranges, such as cars under $17,000, like the Mitsubishi Mirage, or models near $27,000, like their luxury counterparts.
