Update: Fisker Karma Electric Car Gets Worse Mileage Than an SUV

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 in all electric mode (we will ignore the gasoline engine for this analysis).

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 Forbes.com 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 the 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

…Press responses from Fisker Automotive highlight the problem here:  electric vehicle makers want to pretend that the electricity to charge the car comes from magic sparkle ponies sprinkling pixie dust rather than burning fossil fuels.  Take this quote, for example:

a Karma driver with a 40-mile commute who starts each day with a full battery charge will only need to visit the gas station about every 1,000 miles and would use just 9 gallons of gasoline per month.

This is true as far as it goes, but glosses over the fact that someone is still pouring fossil fuels into a tank somewhere to make that electricity….
