The stainless steel body of Tesla’s Cybertruck is reportedly leading to issues with gaps in between the panels::The Cybertruck’s steel is made in “coils that resemble giant rolls of toilet paper,” WSJ reported.

Panel gaps are just a ubiquitous feature of a Tesla. This isn’t a surprise, and the apologists will say it’s no big deal.
I am not a car guy. Would gaps allow water to come in and causes issues as well as act like asail increasing air resistance?
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!
Seig heil! Seig heil! Wait, wrong person… Or is it?!?
It would slightly increase wind resistance. Every car has weather stripping, making water not a concern even for comparatively very large gaps.
LoL some Tesla’s dont even have drainage tubes installed or weather stripping missing or installed incorrectly like needing an article about it
Also if you look up just “water leaking” and “tesla” you will find their forums full of people saying their cars let in water and even one person saying it gets in when they use a car wash and Tesla saying its normal and to just hand wash the vehicle from now on.
Some level of gaps is totally normal but this is a shit show.
You should see the videos of model Y owners (a model they’ve had many iterations on) roll down their window during rain to get a drive through order and the water pours into the open window directly onto the, you guessed it, button console used to open/close the window and DOOR. I’m sure that won’t eventually cause problems. With OPENING THE DOOR.
And it’s not just falling rain, it literally channels rain from the glass roof directly into any open window. It’s hilarious.

Not a Tesla fan but this article is garbage. Basically all sheet metal comes on coils “that resemble toilet paper” including the metal that other manufacturers use.
Yeah, but other manufacturers don’t try to origami sheet metal into a car.
That’s almost exactly what they do…
The missing point is it’s a property of stainless steel that it remembers being a coil and can unflatten itself weeks later if the manufacturer doesn’t know how to work around that.
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.
“Water? Like out the toilet?”
Please only wash your Cyber Truck with Brawndo™
*terlet
The same thing you can make sangria in?
“It’s just chunks of fruit, I swear!”
It definitely seems like an irrelevant point. All car sheet steel arrives in rolls.
I’d be more concerned about how it is formed into panels, how resistant it is to corrosion, what tolerances parts have, how easy is it to replace parts, whether there are visible production flaws due to it being naked steel, and if construction techniques or material thickness makes it more dangerous to occupants or pedestrians in collisions.
I certainly won’t be surprised if pictures start appearing in a year or two of cybertrucks that have been completely fucked by salt water corrosion, or heat warppage or other issues caused by their design.
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)
yeah. panel gaps aren’t a sheet metal issue, it’s been a Tesla issue since forever.
When they make plywood it comes wrapped up super tight in a tree
Has anyone complimented your genius today?
If they were smart, they would pursue nitinol body panels or a similar memory metal. Get a ding in a panel? Take a heat gun to it or leave it out in the sun and the dent is gone. Another benefit would be a ~25% weight reduction.
All they would have to do is figure how to make large panels; which is no easy task, but neither is rocket science. The patent licensing could be a major revenue stream.
Isn’t this what Saturn did or is nitinol some sort of metal alloy?
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?
Is that the lore behind the healing walls?
AFAIK they did plastic fenders and nothing with “exotic” alloys.
Watch what happens when people eventually discover what completely flat panels of sheet metal do in heavy wind.
There is literally a reason why no other auto manufacturer uses flat body panels on cars.
Just so I know, what does happen?
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.
they get real flappy
And LOUD.
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.
I saw one of the “RC” release candidates in the wild in San Francisco two weeks ago. It looked like shit in person. Marker lights weren’t aligned, the stainless already had fucked up scuffs and discoloration, etc. Water spots showed up just like my stainless kitchen sink.
You can see the stainless smudges and water spots here. I wish I got the tail lights when the brakes were off.
Also, the brakes flashed at you. Super annoying.
The lights look so shit. Never noticed before
It’s not even smudge free stainless? LMAO
Similar to the one I saw in Oregon a few weeks ago. It had fingerprint smudges all over the body. Seems like it’d be a huge pain to keep clean and probably need a sealant or clear wrap over the top.
QC issues aside, the design is pure ass
Right? It’s not even a truck, but is somehow even worse.
I thought it might grow on me but the flat tailgate looks absolutely atrocious like a door on some shitty commercial freezer or something.
I think I’d be more into it if it had a more distinct bed like a big El Camino
It’s one of the biggest pieces of evidence (besides X…) of Musk’s growing mental illness and bubble of sycophants. I’m sure many very respected people in the field told him this would be a Very Bad Idea. I doubt any still work at Tesla. They should’ve had the first EV truck to market, now they’re left only with this abomination.
That thing is hideous.
I truly applaud the attempt to radically innovate, from stainless steel to eliminate car rust (how much of it truly is stainless, mechanically speaking?), to major aesthetical design overhaul (even though it does not appeal to me at all). With so much innovation, delays ought to be expected
That being said, everything else is just atrocious. Production issues are blamed on unexpected delays because of innovation and vice versa. It just screams project mismanagement. This thing should’t have been revealed at all. Also, why the fuck does this have bullet proof glass? A truck for the apocalypse? Are they trying to sell an APC? Who asked for any of that?
The oligarchs are preparing for the apocalypse they’re bringing about themselves. This is the car they’ll be driving through the rubble.
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.
I wouldn’t call any part of this innovative
Idk, it’s kinda innovative to see musk finding new ways to shoot himself in the foot
The glass isn’t bullet proof, although it’s toughened. The body panels are supposed to be bullet proof (obviously only up to a certain point, as nothing is ever bullet proof against everything).
I think the bullet proof nature of the panels is more of a happy accident with the stainless being used just being very tough to begin with.
This isn’t even the first time this has happened to a Tesla, at this point this particular problem is just expected.
Should have taken a closer look at DMC…
At least the Delorean actually looked cool and had some style
Looked? Thing still is awesome looking!
I wasn’t using past tense to imply it no longer looks good. I used it because the car is no longer in production.
Chill it was a joke m8
Okay? I know my tone in text isn’t always what I intended but I’m confused what in my reply suggested I need to “chill”
Ya don’t gotta be so literal man, tis all. I knew what ya ment. It was just supposed to be a funny snarky comment
Much like the wealthy expert who built his own sub, there is a need to listen to other experts. Your employees that aren’t fired will be the “yes” people
Well at least Elon can pretend that all the panels were within 10 microns of gap when they left the factory, and it totally warped 2 cm (20000 microns) on the way to the customers.
So wait. You’re telling me that materials can expand and contract due to many conditions such as shifts in temperature? Ya don’t say (that was directed at Elon, not you).
Sure, he could say that. It’s still his/Tesla’s fault. Shipping the product is part of the process, and they’d still be responsible for that (or should be at least. Who knows in this dystopia).
He’d probably just say that it arrived in perfect shape, the customer just fucked it up and are lying. Or something like that.
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.
anti-T articles almost as many pro-T. pics or it didn’t happen. did see some showroom, not rc, that are pretty defect free. get ready. delivery day in 2, 1…
This is a problem with all of their vehicles lol
Just today I took a quick look at a Tesla stopped in front of me and saw 3 misaligned parts. In like 10 seconds. Quality is shit.
Just leaving a “Aber die Spaltmaße” comment here.
Cybertruck would be the time machine in a Back to the Future shitty remake if they would make one.
A perfect replacement for the DeLorean: stainless steel body? Check. Failed ego-drive project? TBD but it’s not looking good.
