Fuel economy is a primary factor to consider when buying a new car because it directly impacts your weekly operating costs. In fact, in a nationally representative survey (PDF) of 2,191 U.S. adults conducted by Consumer Reports, Americans identified fuel economy as the the attribute that needs the most improvement in the vehicles they drive often.

Many cars on the market today offer impressive fuel economy, especially when compared with what you may be trading in. However, performance can vary widely across different brands, even among competing hybrids. To identify the top performers, Consumer Reports’ experts put every vehicle through real-world evaluations at our Auto Test Center. Below, we spotlight the most fuel-efficient cars based on Consumer Reports’ overall fuel-economy test results. Each model got 40 miles per gallon or better in our independent tests.

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 electric vehicles. All of the listed cars are hybrids that achieved at least 40 mpg overall in CR’s tests. 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.
