That is just so unnecessarily complex, crap trapping with all sorts of easily damaged areas - it really is not something you wouldnt do for a truck meant to go offroad. Also really hope the wiring going to the hubs is better protected when it's back together. The sway bar setup is pretty cool tho

Elon claims using gigacasting in Model 3 let them remove 600 robots. Downside is less repairability. It's not just a Tesla thing, Toyota, GM, Hyundai, Geely and I believe BMW are also into it.

That's really buying the lede. Essentially stuff that is cast like that is unrepairable. If it is damaged in a collision, the vehicle is totalled, completely unrepairable and bound for a scrap yard. Gigacasting works great in a world where you never own your car though.

I’ve not done any real strength testing on them but I’ve welded a356 cast car parts fine. Is this an alloy that can’t be welded? E: I couldn’t easily find what alloy used but saw several references to Si-Mg alloys so presumably it should be weldable. That’s not the only consideration in repairable but i think that’s what orange juche is getting at. CarForumPoster fucked around with this message at 02:39 on Apr 30, 2024 |

also "repairable" in this context means "repairable for less than the cost of total replacement"

Dubious quote:lighter weight VERY dubious esp depending the design and materials quote:replacing dozens of welded together pieces with one casting Thats possibly likely quote:Elon claims using gigacasting in Model 3 let them remove 600 robots Well now we know that one is bullshit if the transphobic prick said it quote:Downside is less repairability. Basically means the car is totalled even with light damage. Also just taken from one of the articles - quote:Most body shops have done a poor job at embracing EV repair anyway – and that’s even before gigacasting comes into play. While lack of parts and training were an obstacle initially, that’s no longer the case. Like dealerships, body shops seem unwilling to evolve and adapt. Even though gigacasting makes structural repairs after a collision almost impossible, there are still plenty of opportunities for non-structural repairs (body panels, paint, trim, and glass). Body shops are having huge problems repairing EV's, it's not some sort of reluctance to adapt. A Tesla for example is a huge prick of a job to do anything with especailly frame related. Replacing electronic parts is a nightmare if they dont have the right diag tools which more often than not are hideously expensive, windscreens are no longer just a cut out and replace, they have sensors and cameras and you got body computers and safety systems to contend with to boot in trim now too. So it's real loving objectionable that the article writer says poo poo like that when a body shop's job is far more difficult than it was 10 years ago

The difference between what Tesla is doing and locomotives is that the locomotive castings are sand castings, while Tesla's stuff is a gigantic die casting. We've been able to make enormous sand castings forever, since all you do is carve the shape you want into some oiled sand and pour in the molten metal. These giant die castings are made by injecting 600 lb of aluminum into a mold under pressure in a matter of seconds. The technology itself isn't new, but these are the largest die castings anyone has ever made.

Volvo was recently showing their two new "mega casting" die-casting cells (from Bühler), from one of the articles they were saying that they could die-cast one whole assembly that was previously between 75 and 100 separate components that had to be welded together, which translated to a time saving from 30 minutes per finished assembly to 2 minutes.

The cost of repairs on a modern car is like 4x of what it used to cost 12 years ago due to proliferation of cameras/sensors/general computerization. A front bumper now has multiple sensors embedded inside, just like radar/lidar/camera/sensor/heating elements are now part of almost every windscreen. Think what goes into a modern mirror assembly. Everything needs to be purchased as a unit, and then programmed possibly by the dealership. It's not limited to ev's, it's just how cars generally are these days. Teslas are specifically fucky, because you have to go through their designated network for replacement parts. And the wait times are measured in multiple months. Which is part of the reason why insurance companies would rather write off a mid grade repair on a Tesla, the same kind repair that would put Chevy/Ford/Hyundai back on the road, because it could be repaired relatively quickly. It was so bad at one point, that you couldn't insure Tesla with any carrier. In some places, you can only buy a policy through Tesla, and it's pretty darn expensive. Edit: I can't for the life of me figure out why people would go out of their way to make up bullshit stories about Tesla failures, when the reality is wild enough to fill a whole circus.

That said my partner ('22 Tahoe) tapped an SUV ('23 Santa Fe) in the parking lot about 9 weeks ago, front corner to rear corner. Santa Fe required no parts, all labor and paint, $1800. Tahoe required new bumper cover, paint, labor, $4200. Both cars were out of service for 3 weeks. A week and ~$1k each was getting sensors recalibrated.

The electronics aren't the only cause for high repair costs, the body itself can be problematic. Years ago a Finnish car magazine did an article where they inspected several cars that had gone through crash repairs. I still remember the picture of the B-pillar of one car. It had looked pristine to the outside, but when they cut out the outer layer you could see a bar of high strength steel in the inside that was broken in two pieces. That car was completely not road worthy and it was impossible to tell without cutting it open. These HSS bars are all over the body, so the traditional repair of pulling the body straight won't work, it will probably break the HSS worse than before. So the outer body layers need to be cut open to repair the inner components. But where do you find the same type of HSS bars and how will it behave when welded. And how many photos and videos do you have to take of the repairs so you can prove to the officials that the repairs are done correctly.

Everyone's take on the China news was that they will allow Tesla to run FSD on public roads with no restrictions, because CCP doesn't give a gently caress about human lives. Somehow that's great for Tesla, so it's time to buy buy buy!

There might be a way around insurance issues if you can somehow prove you've permanently disabled or removed FSD completely from the hard drive but then Tesla would have to do that so lol I can foresee a fuckton of Tesla owners clamoring to get that poo poo off my hard drive asap
