7. 2013 Volkswagen 6 Hybrid
Miles per gallon: 42 city, 48 highway, 45 combined.Don't let that quiet little electric engine fool you. There's 170 horsepower under that hood, which is still a rarity for a hybrid of this size and price. All that juice doesn't mean the Jetta loses any of Volkswagen's consistently generous features, however. Three feet of legroom in the back, more than 15 cubic feet of trunk space, Bluetooth and music controls through the steering wheel and dual-zone climate control give drivers a sporty European sedan that feels more like the common car than a grand experiment.
