Save Money With These Fuel-Sipping Vehicles

Even when fuel prices are low, putting gas or diesel in your car is one of the biggest expenses of driving. When fuel prices are high, trips to the gas stations can be painful for your wallet. You can reduce the pain at the pump by choosing a highly fuel-efficient model.  

We’ve found the two dozen most efficient gasoline- or diesel-powered vehicles you can find today. Your quest for economy doesn’t have to end with a stripped-down econobox, like the 2019 Mitsubishi Mirage, there are several highly ranked compact cars such as the 2019 Honda Civic, luxury cars including the 2019 Lexus ES Hybrid, and even a couple of efficient SUVs including the 2019 Kia Niro on the following pages.

The quest for excellent fuel economy has moved beyond ultra-lightweight models with small engine sizes and low-horsepower ratings. Advanced turbocharged powertrains and sophisticated engine management systems offer attractive fuel economy without giving up performance or features.

The list is based on 2019 combined city/highway fuel economy estimates from the EPA. It does not include any pure electric models, but it does include diesel vehicles, gasoline/electric hybrids, and plug-in hybrid electric vehicles (PHEVs). We used the combined fuel economy estimates of PHEVs as if they are operated as traditional hybrid vehicles and not recharged from external sources. If a specific vehicle is available with different levels of efficiency, we’ve listed the model with the highest gas mileage. Though some of these vehicles are diesel-powered, we still use the generic term gas mileage to describe their efficiency.

Scores from U.S. News & World Report new car rankings are shown for each vehicle. Note that these numbers can shift based on new information so the ratings shown in this article may not match those found on the individual review pages.

Without further ado, let’s get to the most fuel-efficient vehicles you can buy on the following pages.

We also have rankings of the most fuel-efficient SUVs and most fuel-efficient trucks.
