The tube on CNC lasers are considered a consumable part. They only last so long like a light bulb. And they’re not cheap. Also, CNC lasers take up a LOT of space. The table would likely need to be around 8’x15’ to cut the parts for the Cybertruck, maybe bigger. And they would need dozens...

I can’t imagine Tesla using regular steel for any part of the Cybertruck’s frame. One of the cost savings of using stainless is the ability for the Cybertruck to bypass the paint shop on the production line. All traditional steel (and aluminum) cars are completely dipped in primer after all of...

Good idea!

The specs of the tri-motor are similar to my 2012 2500HD so I was expecting something comparable. HD pickups have jumped up a lot recently with their specs but realistically, the capabilities are still close to my 2012. I agree, aluminum is stronger than mild steel pound for pound. But...

I am just saying the outer "silhouette" can be stamped using a cutting die, no forming or shaping would be needed. The general shape of the flat panel can be stamped out of the sheet instead of being laser cut. This would be much faster and economical compared to the laser.

I am very confident in the Tesla engineers and am sure that the Cybertruck will accomplish exactly what they want it to. I certainly hope they wouldn’t take advice from me. My only concern is that it seems they are not designing the Cybertruck for my intended purpose. I realize I’m being...

My Model 3 an Model Y have the same plastic on the bottom for aerodynamics. This is not structural, it is just for improving efficiency.

I think is is unlikely that Tesla will use laser cutting, as the author states, on the mass produced truck. Laser cutting is a good idea for a one-off product but I doubt Tesla will do this for production. It is much more likely Tesla will use a stamp press to stamp out the shapes of the...

I'm sorry to drag this thread even further though the gutter but here it goes... I think the main disagreement is the interpretation of "exoskeleton". When Tesla announced this I immediately assumed that the 3mm flat exterior panels would be combined with thinner stamped and welded stainless...

My friend, I'm simply trying to find common ground for us to understand each other on. I am trying to understand this conversation from your perspective and I am also trying to describe things from my perspective. I think of "exoskeleton" as a clever marketing term that Tesla came up with to...

Yikes, I never altered your quotes. Everything is here in black and white. I certainly did not mean to offend you. I think it’s most likely we are interpreting the “exoskeleton” in two completely different ways. It seems you had envisioned all outer panels with nothing on the inside. I...

A titanium Cybertruck would be epic. I would honestly be willing to pay >$100k for a titanium Cybertruck but that unfortunately won’t happen. Unless Tesla designed a Mars-spec Cybertruck. Then titanium starts to make more sense. What on God’s earth are you talking about? Of course all cars...

I think if the cast aluminum components are a major structural portion of the frame then this may be a point of failure. This is based on my experiences in the past with repairing cast aluminum. The other problem is you are not going to be able to weld the cast aluminum to the stainless...

It is very reasonable to think the drivetrain and suspension components would directly bolt to the exoskeleton. Cars have been built like this since the 1960s. I restored an old Camaro that was built this way. And don’t tell me, “of course Tesla wouldn’t use 60 year old technology!”. Formula...

That is exactly what I expected. This is the main reason why the Cybertruck required such thick stainless steel that could not be formed into curvy body panels like a traditional vehicle. But the fact that the Cybertruck is going to be using a massive cast aluminum subframe means that maybe...

It is not that hard to read between the lines here. The Gigapress is described as an “aluminum die casting press”. I have experience with investment casting, sand casting, metal fabrication, etc. I have personally worked with foundries designing and manufacturing parts. I have also spent...

I think it is very logical to assume that Tesla is intending to use aluminum. The 8,000 ton die casting press mentioned in regard to the Cybertruck would only be used for aluminum or some other low melting temp metal. Investment casting is generally used for steel or stainless. Think of the...

I am not sure I want Tesla getting engineering inspiration from a toy. All joking aside, I think this approach is fine for a car that is intended to drive on smooth roads. I just don’t like the idea of a cast aluminum frame on an off-road truck. A truck frame gets twisted, stressed and abused...

Cast iron and cast stainless are typically cast in a casting media (think sand), not a casting press. I am positive this means the Cybertruck subframe will be aluminum. Not good news on my opinion.

Tesla is worrying me with this, do they only expect these truck to be highway driven with the occasional light off-roading, like you might do with a new Range Rover? I hope the decision to go with an aluminum subframe doesn’t diminish the Cybertruck’s durability. I ordered a Cybertruck to...
