Interesting article about the Roadster

So, I wouldn't just assume that AWD model S being more efficient is all about having different gearing available.

Are you sure of this as I thought the front motor and gear was optimized for highway speed while the rear was for acceleration. Obviously both come into play but I understood they had noticeably different gear ratios

I am not sure of any of it. I just assume that:
#1: AWD could provide better regen than RWD
#2: The front motor design could be optimized for better efficiency as the rear motor handles more of the acceleration power (as weight bias shifts rearward during acceleration.)
I am sure gearing plays into it too, but I don't think it is the only factor to consider.

By the way, I noticed this article:
All-wheel-drive Tesla electric cars rated more efficient, but how?
and:
Why is Tesla AWD more efficient than its RWD? - Quora

Yes exactly what I am trying to say. "Tesla patent documents suggest that the rear motor is tuned and geared for acceleration, while the front motor is tuned and geared for efficient highway cruising."
