Elon has stated multiple times that he wants to only sell cars with at least 200 miles of range (EPA rating). Currently, the X 75D is rated at 237. The S 75D is rated at 259. Because the X is larger it has 8.5% less range for the same size battery. If Tesla offered an X 60D it seems to me that it could possibly still achieve an EPA range rating of 200 miles (based on the 218 mile EPA range of the S 60D) but would cost significantly less than the X 75D, since the S 60D costs $8.5K less than the S 75D. So Tesla could offer a base X 60D for $74,500, much less than the current base X 75D price of $83K. That could expand the potential market for the X. Certainly there are potential buyers who would be satisfied with a 200 mile range X, especially as the Supercharger network increases in number and density. I think it quite possible that sometime next year Tesla will offer an X 60D, or whatever the smallest battery offering will be at that time. If next year the S battery choices get bumped up to 65/80/95 then it seems feasible to offer the X with those 3 choices as well.
