Cybertruck will be the last Tesla to use stainless steel exoskeleton

Time to face facts folks! It’s not going well. It’s unlikely to get better. You shouldn’t have to beg people to buy this. Forbes + Morgan Stanley do ≠ “torquenews.”

"A recent Wall Street Journal (WSJ) poll reveals that Elon Musk’s favourability among Americans has dropped to 40 per cent, with 51 per cent expressing disapproval"

He was categorically wrong and stridently denied it up until last week.

But that's how development and science and engineering work: You aim for a target that seems reasonable, and work towards it until you cannot. And then, as evidence changes, you change your guidance.

At all points Tesla has promised the vehicles would have the hardware for FSD, so if the hardware requirements change, they'll have to update those vehicles or allow people to transfer their FSD to new vehicles at a discount.

Seems reasonable.

Seemingly that's still better than Biden.

Carbon fiber is much lighter than stainless steel. Carbon fiber's density is about 1.6 grams per cubic centimeter (g/cm3g / c m cubed), while stainless steel's density is about 7.85
g/cm3g / c m cubed
. This means that carbon fiber is about five times lighter than stainless steel.

However, carbon fiber is less good at temperature changes and compression. The failure mode of carbon fiber may make it unsuitable for a crumple zone replacement for hardened steel.

It would be good for the stressed skin part, though.

Don't get too excited, that poll was before Elon "gave his heart" and other recent events...

BMW figured it out for the i3, frame and body as I recall.

I don't care either way. I just find it hilarious that there is such a thing as an approval rating of a CEO by the general public as opposed to shareholders.

Normally it wouldn't matter but in this case the CEO is highly correlated to the brand. As a shareholder that affects my approval rating of him.

It was not a replacement for the high strength steel members, though, or the crush cores.

I don't see a contradiction. As a shareholder it is within your rights to disapprove of the CEO. I thought the quoted message mentioned Americans, not Tesla shareholders specifically.

Sure, but the total weight of all the stainless is maybe 300lbs? Take off all the stainless and replace it with nothing, and you've reduced the weight by less than 5%. You've also made it less strong and significantly less safe.

It used aluminum frame components

" The Drive Module integrates the drive system, battery, and chassis components with the chassis frame. This structure serves as the foundation of the Life Module, which is essentially the cabin or passenger cell, which is made from CFRP (carbon-fiber reinforced plastic) and equipped with all of the controls for operating the vehicle. The rear of the frame is made from aluminum die cast, on which the five-link rear suspension system is mounted as well as all of the electric drivetrain components such as the electric motor, gearbox, and inverter. The design of the frame functions to support the front suspension to absorb impact energy in the event of a frontal collision by using a combination of extruded aluminum, aluminum die-casting, and welded aluminum reinforcement plates. Also, the strength of the frame is increased through reinforcements welded with aluminum piping. In addition, the Drive Module is constructed so that the battery is located in a sturdy aluminum housing mounted in the underbody section of the frame, below the cabin at the center of the vehicle. "

It did, and I'm pointing out the relevance of the gen pop disapproving a CEO. It affects the company and thus the shareholders.

I don't know the weight of the SS body so you could be correct, but carbon fiber has a high strength to weigh ratio. Example:

You mean things like seizing access to everyone's private government data might make him less popular?
