The "new" 60, that's really a software locked 75 got me thinking. If Tesla has the margins to be able to offer a single battery with a software lock on the Model S and still turn a profit, It's probably going to be the same on the 3. One battery, software locked at the low end, full realized (no lock) on the high end. Simplifies manufacturing not just from the battery side, but also the power output required for "P" models and faster supercharging speeds would all be included in every car. Less different hardware, less inventory of parts, simple repairs. Probably software unlock for the high end charger like we have currently on S & X. The model 3 might be heavy on the options that are software unlockable. Thoughts?
