There have been a few recent cases on the Model 3 Facebook group where someone who ordered and paid for a Perfomance car was delivered a base Dual Motor one instead. The only indications were the nerfed performance and the lack of a Red Line on the car status screen under Dual Motor. In one case, they pushed a software update to the car, and BAM, it now has the Red Line and proper acceleration! I think this shows clearly that the P is nothing more than a software upgrade over the D, and all the talk of “hand-selecting” the motors with “greater burn-in” and more thetans or whatever is really just a little marketing talk. The motors in both cars are the same, the software is what makes the difference. The good news is that I highly suspect all you Dual Motor owners will be offered at some point in the future to upgrade your car to a Performance for a small fee.
