I have a maxim, "KWh can not be made equivalent to mpg".
I mean that there's no single, universal conversion factor, because everyone has different priorities and a different time-frame of interest.
@Jim: I really doubt it's ignorance at work at the EPA. Anyone with a good understanding of thermodynamics is aware of the flaws in direct BTU equivalence methods. I believe it is a concerted effort to drive early adoption of EVs (which have national security benefits, etc.) despite their modest environmental benefit.
In the case of the X-Prize, I again propose an ulterior motive: to generate exciting numbers like 200+mpg(e), in order to capture the imagination of young folks and get people to demand more than the 50mpg cars that are on the market today.
