That's problematic. Don't forget: some people will pay more for efficiency; the bottom line isn't always cost.
On top of that, people pay anywhere from 5 or 6 cents all the way up to 20+ cents per kWh for electricity, so quoting a MP$ figure for electric falls apart there. The price of fossil fuel doesn't see the same kind of spread across the country (some, but not that much).

I bought a windmill which will take 7 years to pay for itself, just to save from buying 17,500 kw-hrs @ $0.10 over that time. That's the cost I'll pay.
I was just looking at the bigger picture, it's good that electric cars fit the job in a lot of places. But for the sake of comparison the dollar is fairly consistent over the US at least. That's how i will know what some people will pay for efficiency.
If i say my energy cost is 16 miles per $. Then everyone can compare their cost in their location.
Would it be easier to quote miles per kw-hr, rather than trying to figure out how many gallons the power plant had to burn?
Since this post is about an efficiency test of an electric vehicle, I don't know how to convert that to other energy sources for the purpose of comparison.
