Fisker Karma Electric Car Gets Worse Mileage Than an SUV

Forbes - The Fisker Karma electric car, developed mainly with your tax money so that a bunch of rich VC’s wouldn’t have to risk any real money, has rolled out with an nominal EPA MPGe of 52.

Not bad? Unfortunately, it’s a sham. This figure is calculated using the grossly flawed EPA process that substantially underestimates the amount of fossil fuels required to power the electric car, as I showed in great depth in an earlier article. In short, the EPA methodology leaves out, among other things, the conversion efficiency in generating the electricity from fossil fuels in the first place.

In the Clinton administration, the Department of Energy (DOE) created a far superior well to wheels MPGe metric that honestly compares the typical fossil fuel use of an electric vs. gasoline car.

As I calculated in my earlier Forbes article, one needs to multiply the EPA MPGe by .365 to get a number that truly compares fossil fuel use of an electric car with a traditional gasoline engine car on an apples to apples basis. In the case of the Fisker Karma, we get a true MPGe of 19. This makes it worse than even the city rating of a Ford Explorer SUV...................Read more
