As hinted way back in November, Chevrolet has come out with a new version of its Volt hybrid electric vehicle in time for the 2015 Detroit Auto Show this week. If there's a common theme to this new EV, it would be "more". The car boasts of an increased EV range of 50 miles, 420 miles if you count on the "extended range" mode. It now also boasts of five seats, up from the previous four. The only thing that seemingly didn't increase is the weight of certain parts.
