Best gas mileage cars

Because it’s such a subjective term—and it involves several factors—there’s no one-size-fits-all definition. For example, many gas-powered passenger cars exceed 35 miles per gallon (mpg), with hybrids regularly exceeding 50 mpg and electric vehicles (EVs) topping 100 mpg. Meanwhile, a standard truck may only get 25 mpg.

So compared to a hybrid, the truck gets poor gas mileage—but compared to other trucks, it may be the most fuel-efficient option.

Keep that in mind as you research fuel-efficient cars. Narrow your focus to the types of vehicles that make sense for your lifestyle, your budget, the weather in your area, and the amount of driving you do. From there, start looking into gas mileage.

Which older cars have the best gas mileage?

While the average cost of used vehicles has skyrocketed over the past few years, many of these cars—even makes and models that are 10+ years old—still provide good gas mileage.

The higher your budget, the more vehicles you can consider—especially when it comes to hybrids and EVs. But even if you’re looking for a relatively inexpensive used car, you should be able to find plenty of fuel-efficient options. Just keep in mind that older cars typically have more wear and tear, so be prepared for additional maintenance expenses.

Keep in mind this is only one publication’s list, and it’s also not a comprehensive list of the most fuel-efficient vehicles on the market. As you research new vehicles, consider additional factors, such as safety ratings, depreciation, and suitability for your lifestyle.

Are hybrid cars worth it?

Ultimately, that’s up to you. In many cases, hybrid vehicles cost more up front than their gas-only counterparts. So if money is tight at the time you’re shopping, that extra cost can be a significant hurdle. Plus, if you don’t drive that much, you may find the financial benefits of a hybrid’s fuel efficiency take years to balance out the higher upfront costs.

That said, if your lifestyle involves even an average amount of yearly driving—and you’re able to spend a little more at the time of purchase—a hybrid car can provide significant value.

The cheapest electric vehicles

New (and relatively new) EVs aren’t typically considered inexpensive—for example, the cheapest car on the list below has a starting price of $29,280. But if you find one that fits your budget and lifestyle, EVs and their 100+ mpg fuel efficiency can be excellent money-savers.

According to cars.com, here are the five cheapest electric vehicles, as of April 2024:

• Nissan Leaf: $29,280 starting price
• Mini Cooper SE Hardtop: $31,895 starting price
• Hyundai Kona Electric: $34,050 starting price
• Hyundai Ioniq 6: $38,650 starting price
