#32Why would you need bulletproof glass?
Working pickups in the wild are subject to lots of sharp impacts that regular cars do not normally get. Glass is a big problem.

#33Basically: the stainless steel, hard edged design has quite a few cost-savings for manufacturing but may effect aerodynamics, weight, and durability (large flat sections of metal are more likely to dent than curved). It will be interesting to see how the pros/cons play out for Tesla with the cybertruck!
The whole stainless steel thing is fascinating to me. The other really famous car made of stainless is of course the Delorean DMC-12.
"Well, if you're going to build a time machine, why not do it with some style? Besides, the stainless steel construction made the flux dispersal.....watch out!"
I always wanted the rest of that line. As though the writers had thought up some way to make 'stainless steel' a necessary part of the the time machine construction.

#34This was the most compelling explanation of the visuals. They are saying that Telsa put function radically over form to reduce manufacturing complexity and efficiency. This is a purely utilitarian approach that is not self-evident. I hope Telsa will put together a better presentation to explain this to the public. This is the sort of technical progress you'd like to see in other domains.
unconvinced. long, precise, sharp angles are expensive to stamp on thick steel plates. so I've checked around the pictures, apparently the marketing material has seams along the angle, but the car in the presentation has angled plates. something doesn't add up https://imgur.com/a/HO1HnGC
Is there any reason they wouldn't just make those independant panels and weld those joints? It's a little slower than stamping, but cutting and welding panels like this is well within the capabilities of their existing robots.

#35Earlier quoted context omitted.
The high sides are for overall stiffness, compensating for the flat sheet steel, which is for cheap manufacturing.
I know, I read the article. We're talking about the utility of the design they ultimately wound up with, the "why" doesn't alter that. Designs are always a trade-off, the question is did they trade-off the correct things to make a really good utilitarian truck ?
It's function over form from a DFM standpoint, not utility. Case in point, if they cared about utility, they'd quote torque numbers instead of 0-60 times. Not to mention the laughable sides and glass top.

the metallic finish made the entire care near un-repairable. It showed flaws exceedingly well, and the properties of most stainless hinder most efforts at regular dent and ding repair.
Aside : I got to smog certify a DeLorean when I was a mechanic in a previous life. It's one of the most memorable cars I have ever had the pleasure of driving. It wasn't that great a driving car, but it was just such a neat image to see in real life.

Wouldn't it be more easy to maintain because you could just sand and blend away defects as opposed to dealing with paint where flaws are more noticeable.
Re: Tesla's Cybertruck Approach on Auto Manufacturing and Engineering
#38This is the truck Howard Roark would build. Function over form for good reason and to hell with the critics. I for one absolutely love it.
How is it function over form? They use electric motors on the door handles, bed cover, and ramp. They made the bed sides super high and hard to access the bed. It has no floor tie-downs. They gave it a glass roof where you'd lean stuff from the bed! This is absolutely form over function, they just picked a form which is controversial. PS - I actually like the Cybertruck. But I'm self aware to know it is due to all th…
I agree from a consumer standpoint, but the article makes a great argument for the form being very functional from a manufacturing standpoint.

>Working pickups in the wild are subject to lots of sharp impacts that regular cars do not normally get.
realistically this vehicle has very few of the traits needed in a work pickup.
Expensive and remote repair, lots of gadgets to break, difficult to remotely fuel, very likely costly compared to the cheapest alternatives.
It's like an anti-Jeep.
This seems to me to be like an electric Honda Ridgeline; a truck made for grocery-getting, mall-hopping, and very light offroad duty.
Also : there are glass formulations that are better suited for tear and puncture resistance than bulletproofed materials. There are trade offs when those materials don't need to deal with the same kinetic energy as a bullet, but i'm not educated enough on the subject to say much more.

paint can be filled and repainted, bare metal cannot without exposing fillers and ruining the finish.
realistically no one is blending the metal during most repair jobs; the panels either get replaced or bondo'd, sadly -- unless we're talking about vintage or nostalgic cars that have inherent issues with panel supply.
