Came across these while in Death Valley a couple weeks ago. The Karma, from Fisker Automotive. They’re on the verge of production. The Karma is equipped with an electric drive train that is supplemented with a gasoline generator. One can drive 50 miles without using a drop of gas, and with the additional help of the generator, the range is extended to approximately 250 miles. The Fisker people were range testing on this day.
