“Super charging requires some serious electrical service. I doubt they would allow free charges. Tesla has free super charging for the 85KWH models, but one needs to pay additional money to enable the feature on the 60KWH model. “
The ‘60KWH’ model is the same as the 85KWH model with software to limit it to 60.
They did the same thing for the early 40KWH. Hardly anyone want that one, so it would make sense that they discontinued it just went with one battery pack.
