All existing Tesla vehicles that can use the superchargers can use them for free. Unfortunately that means no Roadsters, for reasons involving AC-vs-DC charging (c.f. Q&A at the 2013 shareholder's meeting). You also only get the supercharger gear for free with your car if you buy one 85kWh models (which does necessarily not mean the most-expensive... 85kWh models start at $72.4k but go up from there, into six-figure territory). If you buy the cheapest Model S, at $63k, you can pay an additional $2k to buy the equipment necessary to use the superchargers. Model Xs will have a similar situation, I think. I haven't yet seen a commitment that the "third-gen" cars (currently touted as aiming for a $30k price-point, though we shall see in a few years), but it's certainly how Elon talks about it. He's also said that OpEx on the supercharger stations is very very low: little or no rent, little or no power costs. And it's obvious that a major goal for him is moving personal transport off of fossil-fuel; charging at home off the grid doesn't _actually_ achieve that, but giving away solar-powered juice at stations does. So we'll see. <snark> If only there were a way, on the internet, to spend half a minute researching one's uncertain theories, before posting comments on HN. Yes, half a minute is all it would have taken to learn that your claim was mistaken. </snark>
