They will very likely have some casting in the Semi but unlike these cars the Semi will be a Body on Frame design so these structures will be less load baring then they are in cars.

The Cybertruck will use it for the back-end but the structure will be in the exo-skelloton.




Thanks for that. I didn’t know these details. Is the body on frame design standard for semis?


Yes, the majority of pickups as well. Cybertruck is one of a few that isn't. Also some Toyotas and Rivian (I think).


Yes, and pretty much any truck of any size


I wonder if they’ll do anything off the wall like a maglev air ride suspension.


Very, very unlikely. Technologies like that don't just show up in mass production vehicles like that. Tesla want to make 1 million of those a year.

Cybertruck is already quite full of new tech. The Cell-To-Pack structural pack will still be very new. Exo-skelleton and stainless steal is totally unique (Delorian was just stainless panels). Cybertruck will have the upgraded package for 'self driving' meaning new cameras, new chips and so on. It will also have the famous security windows.

What we are not yet sure about is if it will include a higher Voltage for the internal electronics putting power and data on the same cable across the car. Tesla has been wanting to do that for quite a while.


Exo-skeleton from my understanding is marketing for unibody. like most vehicles other than traditional body in frame trucks.

Moving from 12v to 24 or even 48v makes a lot of sense. Not sure what you mean by power and data on the same lines, sounds like a horrible plan.


Eco-skeleton is a unibody, no question about that. But that doesn't make it 'marketing'.

Interior unibody was just always assumed because in cars (unlike planes) nobody ever did exo.

And its not a marketing features as it has a number of real advantages. Part reduction being one and smaller easier bodyshop. Not needing any paint anymore (a modern Painshop cost 500M).

Well we have this things called Ethernet and PoE. Works pretty well for me.


the stainless yes, no paint shop.

maybe I’m just being nit picky, but Poe isn’t power over the same data lines, it a separate set of wires in the same insulation jacket carrying power. I don’t see Tesla switching away from CAN to flex ray or something custom.


Fair point. But Musk actually said he wanted Ethernet at one point. Or maybe he said something like it, I don't remember.


PoE can run data and power on the same pair. Gigabit-PoE doesn't have spare pairs anyway.
