So when I hear they're cancelling the S and X I can't even picture which cars we're talking about.
Of course, that doesn't mean they had to discontinue those lines.
You wouldn't mistake Mercedes S-Class for E-class and E-class for C-class. Even BMW 7 vs. 5 vs. 3 look more distinct than Tesla S vs. 3 and X vs. Y. The Mercedes and BMW do the good job of market differentiation while in my view Tesla failed here, and thus cheaper 3 and Y cannibalized sales of S and X. Thus, paradoxically, given that Tesla started in luxury segment, Tesla hasn't recently been capturing that high margin of the luxury segment (which is doing very well overall - just look at those Maybach and AMG numbers)
Maybe the wisdom of having a 'full lineup' is wrong and has to do with making dealers happy.
On the other hand, having 99% of your sales be 2 very similar vehicles seems questionable strategy.
