*Tesla MYP *SAWD Cybertruck ordered 2/20/26

Elon stated...

“Demand is so far off the hook, you can't even see the hook,” Musk said about the Cybertruck during last night’s Q2 earnings call. “So that's really not an issue. I do want to emphasize that the Cybertruck has a lot of new technology in it, like a lot. It doesn't look like any other vehicle because it is not like any other vehicle.”

Musk said the Cybertruck’s appeal, he believes, has to do with its unique dimensions. “This is the first truck that we're aware of that will have four doors, over a 6-foot bed, and will fit into a 20-foot garage. So it's the biggest on the outside, but it's even bigger on the inside,” he said. “So just trying to get right in the middle of the Goldilocks zone, not too big, not too small, and then really maximize the utility of the volume. And we can't wait to start delivering it later this year.”

this part, is flatly untrue - unless they’re not aware of the many midsized trucks that are 2.5” under 19’, have 4 door crew cabs, and an optional 6’ bed.

but the “Goldilocks” comment likely points towards the answer of what Musk was really saying

It's official. 6' bed and UNDER 19' length. I had a strong feeling that Tesla would make the Cybertruck garageable.

For reference, an R1T is 18.09', a Ford Raptor is 19.30' long.

Thinking on how aircraft structure works (atleast on helicopter that I worked on) the skin is a stressed member.

You will not get the strength and rigidity needed for a large bed payload nor tow weight without some structural member connecting these components.

The advantage of the triangle shape for strength would not be possible with just the structure as shown. I think much like an aircraft has structure and is considered to be an exoskeleton, then the Cybertruck is an exoskeleton as well.


Tesla Cybertruck First RC (Release Candidate) Cybertruck from Giga TX is Out Front of GFTX for Investor Call [7/19/23] CH-47_structure_threequarters_view_Larg

The CH-47 Chinook structure. It is very heavy and if you move it with some of the skin removed, it warps the whole frame. I am very sure it could not support its own weight and definitely not the tons (tonnes) it can carry inside or as a sling load without the skin as a structural member.

I, too, think the relevance of the skin to operational loads largely relates to the issues of payload, towing, and torsion - ie at the rear quarter panels.

and these discussions today wouldn’t be near as fraught with confusion or obstinance if there hadn’t been folks like Munro proselytizing about how “exoskeleton” means there will only be the skin performing operational load bearing

like your helicopter, it’s a mixed bag and what proportion the skin is performing operational load bearing depends on the load type/location

to be fair to Muroe and others, what they’ve proselytized was a fair interpretation of Musk’s comments on stage in 2019

but it was a marketing event, a short description, and always subject to change
