Volkswagen Cross Blue Concept
This car lacks the zippy design of the VW’s Bug, and resembles a traditional SUV without any particular bells and whistles from an aesthetics standpoint. Still, it stands out because of its stunning fuel economy numbers. This plug-in diesel hybrid gets 89 miles per gallon. And that’s in a roomy mid-sized SUV that seats 6, but may be able to even accommodate 7 when it becomes a production vehicle.
