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.

The Cybertruck’s steel is made in “coils that resemble giant rolls of toilet paper,”

All steel is shipped from the steel mill in coils just like that.

Other manufacturers of all manner of stainless products seem to have figured out a solution to the problem.

Two design choices together probably make the problem multiplicatively worse:

  1. Flat panels are not anywhere as stiff as curved panels.
  2. Mechanical parameters of the stainless alloy they’re using (eg it might retain the coiled shape more than some other plain steel alloys).

I can’t get over the flatness… those panels surely rattle too? Or do they void-fill the doors and body with something?

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.

I doubt it will get a type approval in Europe anyway, seems absolutely no consideration for pedestrian safety has been given. If this thing is as stiff and solid as Musk said it was it is also going to fail miserably during crash testing. Having been in a car crash this weekend I can testify how crumple zones save lives. Good thing the whole “but it’s a light truck” loophole they used in the US isn’t going to fly here.

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.

Yes but that can be adjusted. The factory can provide what you need. The design is the limiting factor here. Flat panels are simply bad design.

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

How old?

Early 1900’s: Yes. Metal panels had the same problem, timber panels did not (their thickness stops them from flapping).

Late 1900’s: I don’t think anyone used flat? There were definitely designs intended to look flat (esp 80’s and early 90’s), but there were still subtle curves to those panels to bias them and stop them flapping, as far as I recall.

Happy to be proven wrong :)

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.

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.

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.

I wonder how much better Tesla quality would be if they dumped Elon. Is it a systemic problem, or just poor leadership?

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.

Charging network doesn’t matter anymore for them since basically every manufacturer (save for VW as of this writing) has signed on for the NACS. You should be seeing fords charging at Tesla chargers by either late December or early January.

Battery tech they’re mid on. They haven’t seemed to improve the pack much compared to rivals. Some Chinese manufacturers are even producing better packs.

FSD is something they should continue to pursue, but Elon needs to pull his head out of his ass and accept that things like LiDar and Radar are important additions to the car so that it can continue to “see” even when the cameras aren’t seeing perfectly or at all.

Build quality is their biggest uphill. It could be systemic, but I also suspect there is a bit of “move it along” coming from upper management and Elon. So that’ll never get fixed.

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

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

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.

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)

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.
