Top 10 Most Fuel-Efficient Cars
We've compiled a list of the 10 most fuel-efficient cars currently sold in the U.S. based on the Environmental Protection Agency's miles per gallon ratings for city and highway travel. We considered only those cars that you can refuel at a regular gas station, so there are no electric or natural gas vehicles on this list. In order to arrive at a final hierarchy, we used the EPA's combined fuel economy formula — 55 percent of city mpg rating + 45 percent of highway mpg rating. The rating for each vehicle below is expressed in mpg as a city/highway ratio. All ratings apply to base models equipped with a manual transmission, except for the Toyota Prius, which only comes with a continuously variable transmission (CVT).
