2011 Chevrolet Volt

Cost: $40,280*
MPG: 93 all electric/ 37 gas
Miles per charge: 35 Annual fuel cost:$601-$1,302
Tons of CO2 annually: 84

The Chevrolet Volt is not an all-electric vehicle; it can go about 35 miles on a charge – enough to get most American drivers through their daily routines without needing to recharge or wait for the gas engine to kick in. But the gas engine is there when it's needed, in an effort by GM to alleviate "range anxiety." The cost of the Volt is offset somewhat by a $7,500 federal tax credit, and as much as $5,000 in state tax credits, depending on where you live. It has been named 2011 North American Car of the Year, and also Car of the Year by Motor Trend, Detroit Free Press and Automobile Magazine.
