Cybertruck Body Prototype Casting spied uncovered!! 😲

[TyPope]

mmmm

maybe why it took so long to dismantle the presses in Italy. They were testing and using it for this cast.

They were not. IDRA doesn't have a forge. IDRA doesn't have Tesla's proprietary aluminum. IDRA doesn't have the molds. It doesn't make sense to send that stuff there and build a forge large enough to test the press prior to shipping other than maybe clamping force but even then, it'd be expensive loading up the hydraulics do just have to drain it all for shipping. There isn't much chance it won't provide the 9k ton pressing capability. At the point of shipping, we aren't even sure Tesla had finalized the rear castings. They probably had a good idea but with the adding of 4-wheel steering late in the game, it's possible they only recently finalized the engineering for that one particular part.

Sandy shares his thoughts:

How would two castings with a giant break in the bulkhead be the same strength as one monolithic rear casting. Here is the truth and Munroes reaction summed it up perfectly. The entire rear is one huge casting and people are in such disbelief and can’t even fathom that that they are looking for an alternate explanation. Well, sit down folks because guess what. Elon delivered on his promise and idra came through. ITS ONE BIG ASS CASTING FROM THE REAR OF THE CAB TO THE REAR. That is partly how the CT is going to save cost on fabrication. Munroes first statements. It’s more revolutionary than he imagined and it’s one big casting. This is the future of how vehicles will be made.

See Sandy’s video posted at #363. He pretty clearly disagrees with “ONE BIG ASS CASTING,” at least as represented in this widely-discussed photo.

He disagrees that the prototype is one big casting since he claims the gigapress is not up and running. Tesla will not be welding large castings together for the final version of the truck. If they were going to do that they wouldn't have needed the 9000 ton press. The 6000 ton press would easily handle each side of the truck alone.

If it’s as skinny as what it looks like with the big cast support there, I’m not sure there is a ton of point to it myself. Needs to be a fair bit larger than a bathroom medicine cabinet to be useful. A place to stuff my helmet, bike shoes, maybe a few tools.

I think items that stow fairly flat like shoes and hand tools would fit, a helmet probably not.

You just seemed pretty emphatic that the photo we are all looking at is a single, giant cast. It seems pretty clear that is not what we are looking at with the leaked photo. That is not to say the end product can’t/won’t be a single cast, of course. It just doesn’t seem we have confirmation of that, yet.

I trust Sandy over strong haded opinions stated as fact online <3

Unrelated.. My hope for mid gate remains.

Where do you see the "shock towers"?

I’m making the assumption the top of the wheel well will be the mount for the air spring. I also assume that’s part of the reason for the cast component that extends from the top of the “C” pillar to the top of the wheel well. Creates a triangle, C pillar, top cast, bottom cast.

Crissa, how are you thinking that this is not the giga casting and that there is some future giant casting missing here.

If you won't take my word for it...

Basically there's no mass between the cast bits that makes me think they're one piece. I also think the gigacastings are missing from this image.

Sorry I didn't finish the next four pages of convo this morning ^-^ I slept in.

I'm really not sure what to think of the picture other than that I 100% believe this is what was under the white wrapping outside GigaTexas a couple weeks ago.

I was thinking they assembled this in Texas and what was under the wrap was the actual stainless body. It could be this was what was under the wrap as well. That would jive with the pictures some people think are not from Giga Texas.

Sandy doesn’t have a whole lot of go on either. He said as much on the video.

He was looking for another angle to see if it was one casting or multiple.

Honestly the big shocker about this is the sheer verticality of it. I think we all expected the casting to be limited to the area below the bed height. That’s why I suggested it’s likely 2-4 castings. If it’s one giant casting, that would be huge (figuratively and literally). It didn’t even occur to me that this would be one casting which seems to be Munro’s immediate takeaway.

I think they WANT it to be one casting, eventually. But.. For now? Seems 5 could be likely

Yeah, I get all that. I did consider it.


My thoughts were I think there's a % probability .

They could sit on their hands, and wait for IDRA or they could in parallel create the die, test it , and ratify it. Then they could build test samples so they can fast track the tooling whilst the IDRA is set up in the US.

IMO if it helps to fast track production, 30 million in expense to get it done is not expensive.

How would two castings with a giant break in the bulkhead be the same strength as one...

Because casting is just a way to make parts. For large parts, there's plenty of room to bond them appropriately.

This is how Tesla did it before the Gigapress. They had 2 castings bonded together. They still do it for Model 3 production. It is equally strong, just a bit heavier. Not even too much heavier. The biggest reasons for the Giga Castings are weight reduction and process simplification, not strength. In fact… I’m pretty sure process simplification is the only reason. The rest is a byproduct of that.
