If they have found a way to increase the energy density of the 18650 cell, it could also possibly be a range increase only, in which case it would be on both the S and X
My money is on that.
If they can find a way to improve efficiency (motors from the M3 ?) that would extend range too. 18650 presumably gets them either same kWh and lower weight, thus more range or same weight, more kWh and even more range (and probably even more 0-60 ...). Some efficiency gains elsewhere and all the competition will be backs-against-the-wall. If I were a first-mover, and had that ace up my sleeve, I would play it just as the competition started being real ... and not before.
Just not sure if the current price drops are so that new model, original price, won't annoy recent buyers (although what of the recent buyers just before price drop/re-raise? ... I guess Tesla aren't conserned about that, "
sale made, ownership 3 years, memory short")
So do I buy cheap P100DL now, before re-raise ... or wait for more range (which I would really like).
New Model will be same-old "
Customer base will beta-test" and I'm done with that, so maybe "
most refinement end-of-line, cheapest price" is the time to buy [Tesla]. New model wait would also give me best resale value, as I will be first-with-new-model in the 2nd hand market ... actually, now I type that, its not really a factor in my decision process ... so its "cheap now" or "longer range later, maybe"
