Tesla uses SS301 stainless. DeLorean used SS304.
301 is cheaper, less resistant to corrosion, can resist more force applied to it before failure, formes better in stamping, doesn't tolerate high-temperatures as well.
My guess is they used 301 due to cost and forming properties. Supposedly they use 301 on the Starships, so bulk pricing would help keep production costs low. Had they used 304 the raw material cost and cost of production at volume would be higher but they would be less likely to have these corrosion issues, assuming they aren't welding the panels.
SS301 is a great material. It's workable, ductile, and still plenty hard. It's absolutely perfect for work holding in an industrial spot welding environment.
Why on earth they'd use that for body panels is fucking beyond me. Ok, it's bullet proof, kinda, which is cool I guess? I've never been shot at in a car, I don't know anyone who's ever been shot at in car.
I know lots of people with cars that they don't like to rust. Or scratch tho. Seems like the bigger problem in car design honestly
I believe their intention was to make it more dent-proof which ended up making it bullet proof(ish) at the same. I think that's a good feature. Modern cars are made out of cardboard
That's by design. It's called crumple zone and it saves lives
On cars yeah but I'm not sure if that's so much of a factor on "body on a frame" trucks because the frame does not crumble much. Cybertruck doesn't have such frame because it has an exoskeleton but if you were to make it out of thinner metal then you'd need to add the sub-frame anyway so the end result is still the same.
Also, Tesla has a pretty impressive track record on when it comes to IIHS and Euro NCAP crash tests so I'd be surprised if Cybertruck was an exception.
So what you're saying is not only is it ugly, rust prone, and poorly designed, it's ALSO unsafe.
I haven't said a single thing about rust, appereance or design.
The Cybertruck is an exception tho. It was tested at ~50 km/h and hardly crumpled at all.
Well unlike you I'm a total idiot when it comes to analyzing crash tests so I'll reserve my judgement untill I see some official test results and what experts have to say about them.
There's a video of the test I mentioned
I know. Like I said; I don't have the expertise to make any conclusions from said video. I've seen plenty of videos like that and some of the vehicles get 3 stars and some get 5 but it all looks the same to me. I don't need to have an opinion on this. I'll wait for official test results instead and hear what the people who know what they're talking about have to say.
