I think there is a fairly reasonable way to compare: start from the other end and do it experimentally. Find someone (or better, several someones) who've done EV conversion on say a Geo Metro. Find the same model that's unconverted, have them both drive a measured course keeping same speed &c, and for best results swap drivers in the middle.

Divide gallons used by KWh used, and there's your conversion factor. You can use that to work backwards through the supply chain to get total efficiency.
