10. 2014 Volkswagen Jetta Hybrid
Miles per gallon: 48 city, 42 highway, 45 combined
Volkswagen wasn't going to get into the hybrid game with some underpowered urban grocery getter.
With up to 170 horsepower, a top speed of roughly 187 miles per hour and a seven-speed transmission that's 20% more efficient than most automatic transmissions, the Jetta Hybrid wants to be driven and not just used. Also, its keyless access, push-button starter, rearview camera, xenon headlights, heated front seats, touchscreen entertainment and information system and 15.5 cubic feet of trunk space cut the mileage without paring down the amenities.
