From new lithium ion batteries to updated hybrids, automakers are looking to step up the fuel efficiency of their cars. Toyota announced that the latest Prius model will get a combined 50 miles to the gallon.

The midsize third-generation 2010 Prius will offer even better mileage ratings, enhanced performance, and innovative design features. It will be quieter, roomier, and equipped with advanced standard and available features such as a moonroof with solar panels, four driving modes, Intelligent Parking Assist (IPA) and steering wheel touch controls that display on the instrument panel.
