I had some fun yesterday, dashing off a quick note about the Fisker Karma electric car and just how bad the electric mileage is if you use the DOE methodology rather than the flawed EPA methodology to calculate an mpg-equivalent.
It was the quickest and shortest column I have ever written on Forbes, so of course it has turned out to be the most read. It has been sitting on top of the Forbes popularity list since about an hour after I wrote it, and currently has 82,000 reads (I am not a Twitter guy but 26,000 tweets seems good).
I wanted to add this clarification to the article:
Most other publications have focused on the 20 mpg the EPA gives the Karma on its backup gasoline engine (example), but my focus is on just how bad the car is even in all electric mode. The calculation in the above article only applies to the car running on electric, and the reduction in MPGe I discuss is from applying the more comprehensive DOE methodology for getting an MPG equivilent, not from some sort of averaging with gasoline mode. Again, see this article if you don’t understand the issue with the EPA methodology.
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. This seems more a car to hide the fact that fossil fuels are being burned than one designed to actually reduce fossil fuel use. Given the marketing pitch here that relies on the unseen vs. the seen, maybe we should rename it the Fisker Bastiat.
