With the vast grow of electric vehicles in the market today, General Motors reveiled thei Cadillac Converj. The Cadillac Converj is good enough with capability to run up to 40 miles on a single charge without using a drop of fuel. However, if required, a small gas engine will power the electric motor in order to extend the range up to 400 miles. This elegant and sleek car is base upon the Volt platform. It seems like electric cars are getting more and more efficient today as time passes. It will never be a surprise anymore if eventually, electric cars will already be as powerful as the gas powered ones.
