Fuel economy is one of the most important factors to consider when buying a new car. Even when gas 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 most fuel-efficient cars based on Consumer Reports' overall fuel-economy test results.

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, like the Honda Clarity and Toyota Prius Prime. All of the featured cars are hybrids.

All but one of these models include our Green Choice designation, which highlights the vehicles with the cleanest emissions. You can read more about Green Choice here.

Complete test results can be found by clicking through to the model pages. Note that not all of the models below are recommended vehicles.

Is an Electric or Hybrid Car Right for You?

With longer-range batteries and more places to charge, electric cars are becoming a popular choice for drivers who want to reduce their consumption of fossil fuels. On the "Consumer 101" TV show, Consumer Reports expert Mike Monticello explains to host Jack Rico what you need to know about this technology.
