I was really hoping the topic of MPGe wouldn't come up, as I think we have enough threads on it already, including a thread where I express my opinion that the EVWorld article is an example of one-minded and misleading EV advocacy, and that a world without refineries would be dark indeed. But since the topic is up, I have to mention that the X-Prize's MPGe figure is off by a factor of about 2.5 by CO2 equivalence or life cycle energy content. That being the case, only the Lion, the XTracer bikes, and the three Edison2 cars meet the 67mpge criterion.
When the X-Prize announced their 34KWh/gal figure, I cringed, and Jack McCormack said it was one reason he didn't enter his car, which I think is a shame.
I am happy for (PH)EV operators who enjoy their hobby, and who bring a diversity of fuels to our collective fleet. But the 34KWh/gal figure produces some utterly ridiculous figures, as Patrick's post details well.
