Electric cars like the Nissan Leaf and Chevy Volt top the list, but overall the number of fuel-efficient cars that get 30 mpg or better is growing. Two fuel-efficient SUVs and one station wagon make the list, too, thanks to hybrid and clean diesel technologies.

The first all-electric car on the road in the U.S. is the Nissan Leaf, and it's getting a lot of positive reviews. While it's price tag seems high, federal tax credits push the cost down to around $25,000, and several states have additional credits that can drive it down as far as $20,000. The batteries have long warranties, and Nissan points out that – unlike any other mass-market car – the Leaf costs almost nothing to maintain, since its electric engine doesn't even need regular oil changes.
