My guess is weight reduction refers to the parts, not the entire car.
That is a certainty. However we cannot tell for certain that the savings refer to original 2018 Model 3 or the dual-piece Model Y. The very high percentage suggests it might be a comparison with 2018-Model 3. Regardless it is a certainty that the process will save substantial euros, reduce costs in assembly, reduce warranty costs and improve vehicle stability on several metrics.
Overall this probably ranks along with the Octovalve in terms of contributions to a virtuous cycle.
The good Mr. Munro sounds like a converted fanboy when discussing these two developments.
...next comes battery day!
It is a trifle difficult for me to understand how TSLA is advancing at unprecedented speed on so many fronts simultaneously.
For more on this topic just look at the GF-3, GF-4 and GF-5 flyover videos. Pilings are already going up in Texas and the site has not yet been even cleared completely. Brandenburg shows new buildings appearing nearly every week, with structures in place in days, not weeks. The time lapse of Shanghai speaks volumes.
As we consider whether the share price is excessive, just review all the facts, then reconsider. Then glance at Consumer Reports for the US perspective. Then review the German views.
With all that we can easily see that the virulent complaints are, at worst, growing pains. In all probability they are mostly outliers. Despite that we all know the most serious problem is customer service and lack of access to service. Norway and parts of the US are poster children for those problems. Most of the evidence suggests these issues are being addressed, including recruiting data and Guillen letters about, for example, NE US service centers.
Even at all time highs one cannot be pessimistic. I admit I sold a few shares last week, but I will not sell more fo them. I will buy more as cash becomes available.
