Motor Trend says the Volt has some of the most advanced engineering ever seen in an American car. The Volt can run up to 50 miles in pure electric mode before a backup gas engine kicks in to give it more range.
Motor Trend also said Tuesday that the car is a great value. It costs $33,500 with a federal tax credit, but will likely be cheaper to run than a traditional hybrid. The Volt goes on sale next month.
The award was good news for General Motors as it prepares an initial public offering of stock on Thursday.
Automakers often cite the Motor Trend awards in advertising. Last year's car winner was the Ford Fusion.
