9. Chevrolet Cruze Eco $20,490
While the recently introduced Chevrolet Cruze Diesel is getting all the headlines, buyers should recognize that model is a bit on the pricey side, costing $25,695. On the other hand, the more affordable Chevrolet Cruze Eco still manages to get 42 miles per gallon on the highway, and costs $5,205 less at just $20,490. Using a 1.4L turbocharged engine the Cruze also employs several fuel-saving features to reach its lofty fuel mileage goal. Active grille shutters, underbody panels, a lowered front fascia air dam and a decklid spoiler all work together to make the Eco a more green vehicle.
