That labor estimate was based on a 10K/wk run rate. At 5K/wk you'd estimate $20K/car in labor, and at 7K/wk you'd estimate ~$14,300/car
Further, the current bty cell cost is approx. $100/KWh so the Medium Range Model 3 (L3MUR w. 267mi rge) costs approx $2,650 less due to containing fewer bty cells.
So the current cost of a L3MUR can be estimated to be about:
Dec 2018 L3MUR Cost = (18,000-2,650) + (14,300) = $29,650
Add in Tesla's Q3 Gross Margin at +20.4% to get a base selling price of $35,700
So, Tesla likely could already sell the L3MUR for $35.7K before options and be just as profitable as in Q3 (
based on the German teardown cost estimates).
Clearly, Elon has his profit goals set
*slightly* higher than 2018Q3.
