The 2014 Toyota Highlander Hybrid offers a serious increase in efficiency over the standard model without compromising its power, comfort, or parent-friendliness.

During the course of our testing, the Bully Dog WatchDog proved to be alternately simple enough for a novice to use and complex enough for our car geek tastes. It'll help you boost your fuel economy within reasonable limits, but don't expect it to be an mpg magic bullet.
Volkswagen's new hybrid system in the 2013 Jetta is a winner, delivering good driving characteristics and excellent fuel economy, but the cabin tech lacks features for a car in this price range.
When optioned well, the 2014 BMW 428i achieves an excellent balance between being an exciting sports car and an everyday driver with modern, connected tech, and it looks good doing it.
For serious car geeks with an engineering bent, the Fuel Efficiency Adviser will provide a satisfying array of data, but others will be overwhelmed by the complexity.

The 2014 Ford Fiesta EcoBoost gets extraordinary fuel economy, but the skill required to drive it and the limited options available will limit its appeal.
The 2013 Lexus ES 300h is a solid option for drivers looking for a premium hybrid. Unfortunately, its cousin -- the 2013 Toyota Avalon Hybrid -- is just as good, but a much better value.
