Would you buy a 2 mm CT

[anionic1]

The 1976 VW Beetle had 22 gauge (0.70 mm) sheet metal. The cybertruck doesn't have sheet metal over "struts" or whatever the supporting structure is called in the vehicle industry. It needs the additional skin thickness in order to meet specs.

It will have struts. It will have internal stamped body components. You can see them on the CT website and in the patents. People act like the exterior stainless panels you see are it. The entire body. That will definitely not be the case. The internal body framing will be lighter but it will be there none the less. 2mm would seem more than sufficient Partly one risk of going thinner without stamping is that you can get oil canning in plate or coil steel and the stiffeners required to mitigate that would likely cost just as much as going thicker on the steel.

It can survive re-entry.

With over two years more engineering analysis, Tesla engineers had more time and will have fine tuned many things.

body panels of most vehicles are .7mm to 1mm of mild steel.

2mm cold-rolled 30x stainless steel is many times more rigid.

The bed area of pickup truck is actual two layers ( outer exterior panel and bed inner layer).

Maybe
1. bed outer panels of 2mm and bed inner layer of 2mm
2. doors 3mm
3. front crash crush zone 2mm ( frunk cover, front side panels)

Tesla is very conscious of weight. I mean they reinvented the structural battery pack to reduce weight. I think its likely that they will reduce the thickness of some of the exterior like you mentioned.

The rumor is that during the CT concept development phase the use of titanium panels was discussed.

I also read that Elon wanted 4mm thick SS panels. The 4mm thick SS doors would have weighed 80 pounds and opposed to 60 pounds with the current 3mm thick design.

The durability of the Cybertruck exterior is a side-effect of the exoskeletal design. A 2mm skin would lack sufficient rigidity for structural integrity.

If there was a magic option to swap out the 3 mm ss for 2 mm and it saved you $3000 and you gained 20 miles of range would you take the option?
This would be pretty darn durable, just would not stop bullet like the 3 mm.

WAG weight savings 400 lbs.

I'm just not one to downgrade. Battery improvements will come along anyway, so fuck 2mm. I like my CT as it is.
Frankly, I'm just waiting for the 5 year anniversary Titanium edition, where SS is swapped for titanium (only 1000 will be made). I'm not starting rumors or nothing.

The Cybertruck was designed for functionality, so they chose a material type and thickness of the exoskeleton to meet the functional requirements. The only debate that should engaged in would be a structural analysis based on all of the functional requirements as others have pointed out indirectly. The functional requirements have to win out over weight and cost considerations, and range is really whatever they say that they can meet all other things taken into account. I am not an automotive engineer nor do I have the software to perform this analysis (anymore) but I am certain that Tesla went through rigorous simulation and testing before finalizing the exoskeleton design.

Yet, another consideration is the reuse of the Space X materials (3mm) used to build rockets. Using (reusing) 3mm could be a big economy of scale and an easy engineering plus for Tesla trucks. Do it once and do it better!

I saved 400lbs just by saying no to your wife.

Why, because she wanted you to carry 7 cement bags to the cottage on the weekend for a "project"?
I hate it went that happens...

To be fair, IANAE ("I Am Not An Engineer"). I've no idea what the SS thickness should be.

Tesla will make the exoskeleton thickness exactly what it needs to be to function, no more and no less. I've no capacity nor desire to overrule their engineering efforts.

I don't even know why we are talking about it. No matter what we say Tesla will build the truck the way they want to. If they build it the way they showed at the unveiling I will be happy. I know tha Elon is big on delivering a better vehicle than shown at the unveiling, and features like all-wheel steering demonstrate that he is a man of his word. We also know that he has been downplaying increased range on passenger vehicles, but truck range is different because of the increased focus on cargo carrying and towing capability. I happen to believe that he might keep the range prediction the same but maybe say that it can achieve that range with higher-than-empty payload. A 500-mile range with a 1,000 lb payload would make a lot of reservation holders happy. Of course, pure conjecture.

I think their supply is also involved in this decision. It'll be what they can get alot of. And they're working to make thousands of Starships, so... There needs to be some standard.

Yeah. My truck has been to space. Has yours?

 

[Dirt Worker]

I would pay extra for 4mm. I don't want my vehicle to just look tough. I want it to be tough. Buy a Ford if you want a thin skin literally and proverbially.
