Chevrolet Volt a Top Green Choice for Families.
With a tax credit of $7,500, the Volt’s price drops to $25,720, making it an affordable choice for most families today. This hybrid is a real miser at the pump or charging station, getting an impressive 106 MGe when running with electrical power, and a combined 42.5 mpg on gasoline. The car converts automatically to gasoline when the battery becomes spent. Though space is tight, the car can still carry several bags comfortably. Large families, though, should pick another car, since the Volt has a rear-seat capacity of only two.
