From what I can see, the margins on the other models are similar. And the company still loses money overall.

That is more recent (July) and shows 30% on the long range, without dual motor or performance bumps, all of which are probably really profitable add-ons. Of course who knows who is paying this guy to do the teardown/sourcing for the article.
