I’m with you Carissa, where is the firewall, seems a strange omission. The only thought that I come up with is that the firewall is part of the A/B/C pillar cage. Maybe they are using the “cage” with the incorporated firewall to stiffen the cage and isolate it from the crumple zone?
I believe Joe does a quick fly-over to see where he wants to concentrate his efforts. He doesn't use a pre-programmed flight path. He is very careful to not violate Tesla's wishes... One example that comes to mind is that as soon as Tesla covered the windows in the GigaPress area, Joe would not even show those windows in his videos on the off chance, I would guess, that he would show something Tesla was not ready to disclose.
maybe, but you are not going to spend millions on tooling if design is not frozen because engineering cant decide what they want
Engineering isn't Design. And Design isn't Engineering. And Production isn't either of those.
The casting is literally the opposite of an exoskeleton. And as we saw in the crash test videos there are still quite a few steel cross members that are going to get attached to the casting.
Yes, I understand that you don't know what an exoskeleton is.
There is going to be a lot of steel in there. we have already seen that there is a substantial interior steel body. That stamped steel interior body will provide the fire wall. There are also going to be a lot of steel parts attached to this casting near the front. The cross member and the front impact bar is not seen here.

An exoskeleton implies that the vast majority of forces are applied to the exterior skin or shell. We may never know the actual heat map of load transfer. Show me the giant door openings or trunk/frunk on a crab. I think the truth is that calling this an exoskeleton design is a pretty decent stretch. I am not claiming at all that the exterior skin isn't taking loading or even more than normal but it is not taking the vast majority of loading that I would say would be the general understanding of an exoskeleton. I am fairly confident that during the engineering and optimization they reduced some of the skin thicknesses. I would even be willing to go as far as foretelling that all the paneling except for the doors have been reduced from 3mm. Its unnecessary weight and Tesla wouldn't do that. I also think that the 3mm will only remain at the doors to maintain the original claim of 3mm panels and the "bullet resistant" claim. The recent images deviate from the original door patent and seem to show a more traditional stamped steel door interior panel. Which tells me they could have beefed up that interior door structure and thinned out the SS door cladding but IMO they probably wont to maintain the original claim. 3mm steel is 3x heavier than a traditional skin and they have definitely been making reduction to cut weight.
so you say....as an engineer I disagree......I believe design is done by engineering......and production is the product of that engineering feat
Tesla is perfectly happy to "run with scissors". The south end of the factory was a concrete lot only briefly before being torn up and repurposed. The main entryway has been reconfigured multiple times.
building changes are a bit different than something that is going to be sold to the public......design of the tooling is a much more critical than a wall that can be torn down an rebuilt
I look at Tesla's decisions as. Make a choice. Even if it's wrong that's alright. With more data, we'll adjust!
