My favorite Prius of them all:

The Prius Plug-In Hybrid

this car has a starting price of $30k and has the best fuel efficiency of any Prius and has a built in battery plus a charger to give the battery more power. It gives you 50 MPG and 95 MPGe. But you still need to use gasoline. It's the Tech-Savvy of the prius, with solar panels, LED lights and a smart key system already included in the base model!

It's closest competitor, the Chevrolet Volt

 is $5k more expensive, has less room in the vehicle and loses its value way faster!
