Speculation, if there was any major update of S or X, maybe they'd clear all the old inventory. Could this account for the missing showroom stock?
There are clues to look for when suspecting a refresh.
1) making space at the factory for all the new parts, to reduce switchover time. Wheels recently got simplified at the factory so you can't order as many combinations - but that means less stuff taking up space.
2) delivery times go up... suspiciously before a product reveal... but not too soon before the reveal. Two weeks is perfect.
3) Your showrooms will not want to have the old-looking products. Even if you can't get the new-looking products into the showroom for a while, you want to clear out the old stuff. 10 days prior to the reveal.
4) production lines going down? shifts being pared back? This is what happened during the switch to Raven, which was smaller than what is probably coming up.
5) Employee car parking spaces being a bit more available at the plant? I concede some of these things are beyond my ability to discern... help from others is needed.
IMO the S+X will get the new batteries first. It's a low-volume product compared to the others. IMO Elon will want all automotive products to have the new batteries. Panasonic is adding manufacturing capacity (using its old tech) for Tesla Energy, though I would expect some of Tesla's patented tech to end up in the Panasonic machinery, or even, everything gets converted over eventually -
especially if there is more environmental waste/complications with the older tech.
I'm wondering if the Roadster used to have a one-pack-on-top-of-the-other design, but following some of the latest developments they have been able to revise that back to one layer, and re-engineer the floorpan of the car.
Back to TSLA... I'm optimistic the stock can climb back to a neutral or green level by the end of the day.
