Okay, there are some good ideas here. So, what if we follow Jamesqf's idea, combined with dcb's response? Let's have a gasser and an identical EV drive a distance so that the gasser uses one gallon of gas. The EV will use only 3/7 as much energy, or

(34 kWh for a gallon) x 3/7 = 14.57 kWh

So, Jamesqf, there's your conversion factor--

1 gallon of gasoline = 14.57 kWh

Nope, the electric boys wouldn't accept that.
I can't put my finger on it - probably because I've only spent the time it took to read the post thinking about it...

That suggests that a higher efficiency EV in the experiment, what should be an independent variable, results in less energy in a gallon of fuel. This makes my intuition gland tingle.... It not sitting well with me (just yet) from a conservation of energy stand point.
