The Chevy Volt won countless awards for it's clever powertrain that allowed the car to be used as an electric car with a gas backup, or as a fuel-sipping hybrid. The switching between these two modes is seamless and that adds to the sense of the Volt being a proper luxury car. So many high-tech green cars cost a fortune but feel like $16,000 econoboxes, but the Volt feels like the $40,000 car it is. Well done, GM.
