the corporate-speak blurb calls that into question, too. "the permanent magnet machine better solved our cost minimization function.." Hard to know whether or not to interpret that as "This is cheaper, and thus increases our profit, allowing for further production." or "This is more efficient, appealing to a broader market with larger range numbers and ensuring profit." > So, as you know, our Model 3 has a permanent magnet machine now. This is because for the specification of the performance and efficiency, the permanent magnet machine better solved our cost minimization function, and it was optimal for the range and performance target. > Quantitatively, the difference is what drives the future of the machine, and it’s a tradeoff between motor cost, range and battery cost that is determining which technology will be used in the future.”
