8. 2011 Hyundai Elantra

Gas mileage: 33 mpg (29 city, 40 highway)

“There are now a few non-hybrid compact cars that deliver highway fuel economy of at least 40 miles per gallon, but the 2011 Hyundai Elantra is the only one that does so in every trim,” says KBB.com. “In addition to the impressive efficiency, we’re fans of the all-new Elantra’s bold sheet metal, stylish interior and attractive list of standard and optional features."
