No Exoskeleton

Lol you are not the only one!

Do you know how many thousands of words I've written about how it's not an exoskeleton over the years?

Although I think he's a little bit harsh on the definition with the doors, as they are more exoskeleton than the rest.

So the skin won't be 3 mil.

Yup, as I stated recently, exoskeleton simply means "tough exterior." That's all I care about anyway, no paint and difficult to dent accidentally.

I highly doubt it due to weight and material cost.

The Cybertruck needs to remain affordable to sell in high volumes.

Going rogue to say that I think he’s “wrong” here

He may be right about what Monro et all interpreted 2019 unveil “exoskeleton” to mean - and there’s lots of evidence of that Monro thought “exoskeleton” means something that this pre-production doesn’t conform to

But I don’t think Tesla meant what Monro assumed

know what they say about assumptions

Are you linking to the same thing that someone else says is evidence of an exoskeleton?

What did you predict? What time point?

Having stiffened 3mm SS panels will carry load and add stiffness to the structure. Load Bearing may be what is up for interpretation. Bending, stamping or creasing the panels will make them very stiff. They will transfer load thru the attach points and thru the surface. Is it an exoskeleton like an insect? No, it will be structural and load bearing. I hope we get more info and I am sure Monroe will give us the definitive answer to all of this.

"The Cybertruck will be one big origami piece of steel with no support inside" said no one ever.

Cory is correct that the front fender appears to lack sufficient attachment to contribute to vehicle structure. We can't really see the rear fender attachment from the photo in question.

Regardless, we still need the 3mm skin because of that damn sledgehammer

Commonly expressed in the form of a high-speed heavy-duty shopping cart "cart demon" crashing into the side of Cybertruck or the adjacent parked SUV/pickup truck whose door is carelessly flung open into the side of the Cybertruck.

THIS GUY KEYED THE WRONG TESLA
A vandal keyed a Tesla and caused $4800 USD damage, and the owner set out to find him. Get ready because this video keeps ramping up and gets crazier and crazier.

Yeah I'm guessing 3mm on the front and rear doors and frunk...prob 1.2 mil every where else.

They put a bed liner in the bed so maybe that'll be just plain steel under the coating for cost reasons.

As I posted before on various other threads, at 3mm thick the whole SS skin on the CT weighs just 600lbs or about $680 of SS. Of that 400lbs of skin is on door openings, that use the skin for structural support of the doors. Further, by my calculations SS works out to be cheaper than painting steel or aluminium, so the thick skin is not a "waste" nor very heavy in comparison.

The important thing to understand, as Cory also points out in the video, is that the doors are "independently strutural" meaning the skin will help here, but the actual body itself consists of front and rear cast, cabin and structural pack, that forms the structural body in white similar to the Texas MY. Technically, the individual door skins could be considered "exoskeleton", but they in no way form a significant structural element of the main body like some have claimed.

The other thing to note is his argument that "if" there was an exoskeleton skin doing the heavy lifting then they wouldn't need such a large front and rear cast either. So given there's little evidence of a substantive way to attach skins, there is also no real way to transfer loads into the skins. It's also counter productive to transfer loads through the skins intentionally, as the load will try to take the shortest path to the ground, which is through the suspension that is mounted internally not externally.

I also like his comment on design being for purpose, and that semi still uses a ladder chassis like other trucks.

I think it’s pretty close to what they planned from the start. For example, the skin on the sale pillar area could never have been “structural” and also have storage. The doors likewise.

Yeah. Of course, saying that because it has doors means it's not an exoskeleton is like saying a beetle doesn't have an exoskeleton because it has wings that pop out.

Good luck at the “Strawman of the Year” awards
