Less than enthusiastic about this article but perhaps it's because I'm sensitive to the numerous errors--and sloppy language--used by the author. For example, saying "initial sales were only for the 85kWh battery" and "sales beginning in April" for the 40kWh model. A simple replacement of the word "sales" with "delivery" would address the problem. Perhaps, from a financial standpoint, the cars aren't sold until they are delivered?
Saying that only 85kWh models have access to superchargers and leaving out the fact that 60kWh models could with a modest upcharge is an issue as well.
It's a good strategy that Tesla has, using their own reveals, at their own facilities, on their own timetable, rather than relying on the auto show circuit to make a big splash.
