The Most Fuel-Efficient Cars of 2010

Fuel Matters

These lists show the vehicles within each category that achieved the best or worst gas mileage in Consumer Reports' real-world tests. They have selected mpg cutoffs that are relative to each category. For example, a vehicle that gets 19 mpg would not be a standout among wagons, but it would be among the highest in the midsized SUV or minivan categories. Here are some highlights from Consumer Reports' list of the most fuel-efficient new cars.
