Lots of new speculation that the initial cars off the line will only be able to choose color and wheels. Everything else is locked to some predetermined configuration... Hmm. I am confident that will be all glass roof due to the RCs driving around (still hoping "optional" does not mean extra cost), but the initial size of the battery pack is far more speculative. Reasons it will be 75kWh: More margin / profit Best the Bolt when all eyes are watching Reasons it will be 60kWh: Easier ramp on giga factory (5x60=4x75) Better match to Tesla and SpaceX employees (they are clearly supposed to be the first receiptiants and they make only reasonable wages - 60 kwh is a better match for their salaries) Closer to the "35k" car that the M3 was heralded as and it will be measured against Better S/X separation I'm having a hard time believing that Elon is going to tell his employees that they must pony up $50k to help him work out the kinks. Also, seems like the media might accuse bait and switch- to sell a $35k only to say that you only have the $50k available. Just sayin'
