Annual Fuel Economy Guide Updated for 2013I've always said that the best ways to get around are to walk, bike, or take public transit. But if you need a car, you should get the most fuel-efficient model that meets your needs. Thankfully, it seems like there are more quality choices with every passing year. It wasn't so long ago that the U.S. was the land of the big gas-guzzling SUV, and while we're still far from sustainable transportation, there's definitely been a change in the landscape. It's now possible to find many quality vehicles that are frugal on fuel, helping both the planet and your wallet.
Of course, the reference in the US for fuel economy is the EPA's official guide at FuelEconomy.gov, which was just updated with 2013 models. If you're on the market for a vehicle, that's definitely the reference site.
Above is the EPA's top 10 most fuel efficient vehicle including electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs).
Below is the same list, but with the EVs and PHEVs removed to show only plug-less vehicles.
Note that for plug-in cars, the actually efficiency doesn't quite matter in the same way, and attributes like range might matter more in the end. You need to find a vehicle that is compatible with your driving habits (ie. if you do a lot of very long trips, pure EVs might not work for you).
