We know 60, 70, 85, 90 (I hear very few indeed exists as 90 non-D). 90, 100 don't have RWD option. Model X has had D's only. I don't recall any RWD in Model X. Now that 60 is gone, the only available Model S without D is 75. Model 3 is coming soon and I have a feeling that entire Model S will be Dual Motors to keep the production simple. Probably Model 3's will have RWD for good. How many think that RWD will also go extinct?
