Most Fuel-Efficient Car - Honda Insight

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 does not include plug-in vehicles, like the Honda Clarity and Toyota Prius Prime.

Complete test results can be found by clicking through to the model pages.
