alt Hacker NewsWell, Elon said the final prod car would be lighter; whether or not they achieve that goal, the strong implication: the car has a battery and power train in it. Also, we saw it drive up the first part of the ramp without any air seeming to come out the back, and reverse down slowly; there don't seem to be forward facing fans/jets from the looks of the air coming out. I'd say Occam's razor is that the car has a full electric system in it.

I can move my gas powered car that far if I leave it in gear and run it with the starter. Is my car electric?
I don't doubt it's got an electric system in it. I doubt it's got a battery sized for anything beyond that demo, a sufficiently rigid frame for road use, a reasonable steering and suspension system, etc.
My general assumption is that anything and everything that wasn't necessary for that demo was removed to trim enough weight to make the demo possible.
