Underneath the Cybertruck
We have a video from Munro Live, and they are taking a look at and, for the first time, explaining what the under side of the Tesla Cybertruck is like. This is clipped from an image that Tesla clipped during April Fool's day, and Munro Live captured a screenshot of part of that image in order to see underneath the Cybertruck as well as how the suspension is put together.
They noticed right away that some things were painted. This answers some of the questions I had recently about why the Cybertruck was having job openings for painting. The green is lower control arms and look like forward control arms.
The red is the primary sub frame or cradle that carries the suspension and makes primary connections of the controls arms inboard of the vehicle structurally.
The yellow above the sub frame, in the back, is the primary longitudinal rails - it's part of the primary impact structure at the front of the vehicle.
The little green pieces at the top are crush cans and are likely made out of aluminum.
At the bottom of the sub frame is an X looking like metal shape. It's blurry, and it's painted a light baby blue. It looks like a multi-piece stamped steel welding, which has been seen in the past.

Engineering of the Cybertruck
Cory and Jordan then examined a piece of metal that was like what the underneath portions of the Cybertruck were using to mount to. The sub frame on the Cybertruck is very wide and relatively wide on the Model 3 and Model Y.
The one for the Cybertruck is secured with threaded fasteners. This is likely done because it's a different material than what the piece of metal was that Cory and Jordan had. The cross member beam is important for absorption.
You want a frame with all its connections to maintain perfect congruence regardless of how the Cybertruck is moving. This creates safety in the unlikely event that there is a heavy crash involving the Cybertruck. The Cybertruck appears to satisfy this requirement.
They also had a Rivian sub-frame at a high weight and cost penalty. It was made with many extrusions - extra pieces and aluminum. The Model 3 and Model Y cradle is lighter, even with a heavier material.
Tesla typically mounts their power train up on the body of the frame. You can't see this with the Cybertruck view. There is some red sticking out and it can barely be seen. This could be used for mounting the drive unit.
Cory and Jordan want to get their hands on a Cybertruck and peel back the layers to see how the Cybertruck is being made in order to share their engineering knowledge. It was a great video.
What do you think of the discussion about the engineering of this part of the Cybertruck?
