Tesla buys all their tooling upfront, unlike GM who amortizes tooling. And tooling is one of the most expensive parts of developing a new model.  
  
 So... I would expect with Model Y at least 70% of the tooling bills are paid and with the truck about 30% of the tooling bills are paid. 
  
 Should be easy to maintain momentum with model 3 now cheaper in China and maintain profitability.

But we know that isn't true and that they are trying to move tooling to the new patent they filed about a single fabricated piece. Will reduce costs in the long run in big ways, but model Y cannot reuse model 3 lines right? Fremont has to be retooled to support model Y. 
  
 My info might be out of date. I guess see what call says
