Fuel economy is an important factor to consider when buying a new car, even when gas prices are down—they won't stay that way forever. Many conventional cars today offer impressive fuel economy, especially in contrast to what you may be trading in. Further, alternative powertrains offer an increasing arrary of choices, with diesels, electrics, and hybrids each carry appeal for different drivers.  

Measuring fuel economy is among our 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 (mpg).

CR's overall mileage is calculated from equal portions of city and highway driving.

The chart that follows features the most fuel-efficient cars currently sold that Consumer Reports has tested (see our list of the most fuel-efficient SUVs). Also see our Ratings comparison by category (available to online subscribers), which lists each vehicle's overall mileage.
