8.Chevrolet Volt
When it comes to the greenest (and most popular car), the Toyota Prius is considered a runaway winner. In fact, the Prius managed to dominate the category for many years until the Chevrolet Volt enters the picture. The Volt is a worthy addition to the segment, and is giving the Prius some stiff competition. If you run the Volt using pure electricity, the range is at 53 miles and once the electricity has been used up, the gas engine starts its job compiling a total 420 miles in driving range
