The stainless steel body of Tesla's Cybertruck is reportedly leading to issues with gaps in between the panels

LMAO³

Flat panels are not anywhere as stiff as curved panels

Same for windows. So much for "thermonuclear explosion-proof glass", Elon.

Also, the shape has horrible aerodynamics. If it had a combustion engine, they couldn't sell it in large parts of the world due to fuel efficiency.

Point 2 in particular is huge. Depending on the exact alloy steel can vary wildly in characteristics. One alloy might bend almost as easily as aluminum, while another might be nearly as hard as tungsten. Adding to that proper heat treatment and the difference in the mechanical characteristics of the finished product can be absolutely massive.

Don't older cars have mostly flat panels? So it should be possible, right?

QC issues aside, the design is pure ass

That thing is hideous.

I'm hoping shareholders do push him out. They're still in a great position to compete if they focus on the right things (build quality, designing cars people actually want, etc). The charging network is still the best around and they're still ahead in battery tech, but they need to stop chasing FSD and give up on this cybertruck thing.

They said they're a tech company and the car is tech on wheel, so i guess it's just competency and inexperience issue.

dumped Elon. Is it a systemic problem

Don't you know that the revolution eats its children? The electric cars revolution is over. Tesla was part of the revolution. Now Tesla is obsolete and the others are going to take over.

I doubt anything but a man child would have gone with stainless steel.

But the normal Tesla build quality and gaps would still be there. Because that would involve major overhauls and retraining and is never going to happen while the company is successful... And won't happen if the board is looking to sell

I certainly won't be surprised if pictures of that don't start appearing in a year or two because the things still haven't been delivered

(I know, I know, they're supposed to be delivering the first ones in two days, but I genuinely wouldn't be surprised if that somehow falls through)

Has anyone complimented your genius today?

Please only wash your Cyber Truck with Brawndo™

That's almost exactly what they do...

I've worked with stainless steel (specifically 304, 430 and 401) for 15 years and the steel shouldn't have a memory after being run through a de-coiling machine that is configured properly. Excessive heat in a focused area would definitely cause it to warp but this can usually be overcome by adding geometry to stiffen the parts. It seems like the team at Tesla is missing a step somewhere.

What’s funny to me is how fast the Korean car companies learned “metal bending.” They went from generic easy shapes with little forming to adding in creases all over the damn car just to prove they could do it and replicate it, and they did that in the span of a couple decades at the most.

Seems like the answer here is "You're an idiot if you buy Tesla products".

Essy lesson to learn, imo.

Good old fashioned blame the customer. He's so good at it his fanbois will do it for him.

Don't most cars use aluminum as well as carbon steel in their frames, to save on weight?

I think we all just misheard him and he actually said it had macron precision, not micron

Probably not in this case. Most vehicle doors are designed to channel any water that enters the gap. But, Tesla may not be aware of this practice and rely only on the seals.

Don't ask questions, just hail Elon our overlord who can do no wrong!

It would slightly increase wind resistance. Every car has weather stripping, making water not a concern even for comparatively very large gaps.

they get real flappy

Metal does not like to compress at all. But when you make it really thin it will be floppy like a spring you might find in a pen or wind up toy. However you can make it stiff again by making it curved so the sheet has structure/mass going on all directions. Infact believe it or not cars during the 1960/70s had quite a bit of curves dispute being a brick. And that's because they didn't want the panels to dent easily. So when a car has flat faces like the Cyber truck. Those panels don't even have subtle curves to give them structure and they are soo suspectable to dents that a simple brease does the job of denting them.

I assume the flat panels have an aerodynamic effect like the underbody of race cars. They ultimately create forces sucking the surface into a direction. And since on the sides it will be never stable it will flap around all the time. You can see that the most with the vertical fin stabilizer of Formula 1 cars. https://old.reddit.com/r/F1Technical/comments/nd2ayw/alpine_flexible_rearwing/

Here is a lot of wobbling and while the vertical changes are intended, the horizontal ones surely aren't and they tried to make it as stiff as possible. Certainly nothing a production car would achieve.

Correct me if I am wrong, as I didn't study this particular area.

Don’t you put that shit in my head 🤮

Gary Busey as Doc Brown

I don't like you.

And Gary Busey as Dr. Emmett Brown

I had to look it up. I was not expecting your joke to be literal. It does look like Homer's car! Just without the second dome.

AFAIK they did plastic fenders and nothing with "exotic" alloys.

Nitinol is an alloy of 60% nickel and 40% titanium (usually). It can be used in memory materials or to capture energy from heat. Basically it can be bent when it's below a certain temperature (like a regular metal) and it creates force to restore its shape when it's heated.

Yes, I did learn that by playing modded Factorio. Why do you ask?

Sandy Munro lost all credibility when it came out that, while going on about all these wild claims about Tesla's incredible manufacturing prowess and how everyone else was shit, he held a fair bit of Tesla stock and even went on to gloat about how much he made off it during 2020.

Absolutely zero integrity and no reason to trust a single word he says anymore, because not only has he shown that he won't disclose serious conflicts of interest, but that he'll also gladly abuse them for personal gain. He realized he can make way more money shilling Tesla and selling merch than he ever did with his normal business, and rides off his company's past reputation.

Even if you ignore that, his analyses are basically entirely cost focused, and having seen some of the reports on projects I personally know quite well, he takes an incredibly simplistic view towards component design and focuses on almost entirely on cost/simplicity, with basically zero regard for longevity, function, NVH, etc. Which, for the massive 500+ page reports that are purely for cost and build analysis, is totally fine. However, he then spouts it to the public as if everyone else is an idiot for not wanting their cars to be rattling shitboxes.

He'll praise things like Tesla re-using the suspension from the Model 3 1:1 onto the Model Y because it saves on manufacturing costs and such, but will completely ignore that, until some fairly recent part changes, the Y had literally one of the single worst rides of anything on the road today, because they added 100s of pounds of weight and didn't even bother to change the spring rates.

Idk, it's kinda innovative to see musk finding new ways to shoot himself in the foot

I would pick a Toyota pickup run the mother on syngas from wood. Civilization is over but I can still get air conditioning and drive.

Looked? Thing still is awesome looking!
