    Fuel economy is one of the most important factors to consider when buying a new car because it has an impact on your weekly operating costs. This is especially a concern when gasoline prices are at record levels, as they were recently. But even when prices are down, they won’t stay that way forever.

    Many cars sold today offer impressive fuel economy, especially in contrast to what you may be trading in. Below, we spotlight the nine most fuel-efficient cars based on Consumer Reports’ overall fuel-economy test results.

    More on Cars & SUVs

    Measuring fuel economy is one of more than 50 tests we conduct on each car we purchase. Our fuel-economy numbers are derived from a precision flow meter and are rounded to the nearest mile per gallon. CR’s overall mileage results are calculated based on equal portions of city and highway driving.

    This list starts with the most efficient car, and it doesn’t include plug-in vehicles or EVs. All nine cars are hybrids that achieved at least 40 mpg overall in CR’s tests. Each of the featured models has our Green Choice designation, which highlights vehicles with the cleanest emissions. If you’re looking for a fuel-efficient SUV, check out the Toyota Corolla Cross Hybrid, the only SUV to crack 40 mpg overall in our tests.
