What sort of engineering standards are these Cybertrucks built to?

Oh, very rigorous engineering standards. The wheels aren't supposed to fall off for a start.



Can’t be made out of cardboard either.

I saw the title of the post, and I knew somebody would have referenced it.


We’ve taken it *outside* the environment


Same standards as e.g.

2026

Audi Q8 e-tron:

"Popular electric car recalled due to brake pedal problem" [1]

A problem with a "screw connection" (unclear whether this is a mounting screw or it serves some other purpose) can cause the brake pedal to malfunction.

or, in 2024

Audi Q4 e-tron, Volkswagen ID.3, ID.4, ID.5 and ID.7:

"Dangerous error in popular electric cars: brakes can cease functioning" [2]

It says that the ABS pump could drop off which would cause brake fluid to leak out which in turn causes the brakes to cease functioning.

Using a mechanical ABS in an electric car might be part of the problem


As opposed to thoughts and prayers-based ABS?


Some cars are going with entirely electrically actuated brakes, either inboard on on-hub, compared to the E-Tron which uses traditional hydraulically actuated brakes. One uses an electric motor to wind something to tighten the spring clip by pulling it that then pushes the pads to the rotor and the other uses pressure to overcome the spring by pushing the spring to compress it and push the pads to the rotor. I'm guessing Audi didn't go with entirely electric brakes because they have a reputation for being harsh and difficult to modulate with the pedal, and Audi is supposed to be both a luxury and sport brand where pedal feel is important.


Are talking about brake-by-wire? Where brakes are controlled by electric only, and if electrics die, no brakes?

These are dangerous. Cars are not maintained to aircraft standards and will never be.


With electrically actuated brakes the default power off state is fully engaged. Meaning if the power dies the brakes lock up. That causes it's own issues, obviously, but a sudden deceleration is better than no deceleration at most road speeds.

edit: as formerlyproven below states, the ones currently for sale also have a hydraulic backup.


Insane take. They will be vastly more reliable than hydraulics.


Brake by wire passenger car brake systems are still hydraulic... and all of them have a mechanical backup. There is not a single car on the market today using electromechanical brakes.

Unless you're talking about electric parking brakes in a thread about ABS.


Look up cybercab. Their new disassembled manufacturing method cannot support hydraulic lines.


Just remember to pack a bottle of spare magic smoke incase something leaks!


Which cars?


No, just any combination of electric regenerative braking combined with electrically controlled brakes.

It is an electric car after all


Well, the wheels may fall off, the body panels may fall off (weak glue), but the rest of it is OK right? Well, apart from the bulletproof glass?

So worst case you're rolling down the road on a chassis with no body panels, except you're not really rolling if the wheels fall off.

Hmm.. good job we're not letting in those cheap Chinese EV's and sticking to this top quality homemade stuff.


And the hitch might fall off when towing over a pot hole.


The same engineering standards as other Teslas are.

Meanwhile, about 63% of Tesla Model Ys failed their first mandatory inspection in Finland. The Tesla Model 3 did a bit better at 59% of cars failing their first inspection for the same model year. However, they're faring a lot worse than the third worst car, the Dacia Duster, at 23%, or other EVs like the Volkswagen ID.4 at 6%.

To the ones of people who like to move fast and break things.

'Vibe-Engineering'


And they’ll probably just tow the recalled trucks outside the environment.


Into another environment?


No, no, no. it’s been towed beyond the environment, it’s not in the environment



Rush of Australians to the comments section.


IDK but millions of other vehicles are recalled every year and never mentioned here.


At least they aren’t using Full Self Engineering (yet).


Blame it on a loose nut behind the steering wheel.


Indeed. The insane part is not that Tesla built an absolute dumpster fire of a vehicle, that was something that should have been obvious at every point.

The insane part is the number of people who were somehow able to put up $120k for one, and proudly boast how awesome their new car was even though it spent most of its time in the repair shop or breaking doing very basic things, and failing to do "Truck" things that even my hatchback can manage.

Presumably it's not a coincidence that so many of them were bought by brand new weed shop owners.


I once saw a Ferrari trying to negotiate speed bumps and a roundabout. On a road that has a 30 kilometre speed limit.

For me a car is essentially a tool so it needs to be practical. But for others it's a hobby.


It looks like they were designed by a disruptive startup unburdened by the history and experience of designing and building cars.


It was super delayed and I think that's because they couldn't execute in all the ways they promised they would. The final product is very rushed and pretty different from the initial promises. I think they got into "Let's just ship SOMETHING" mode as the delays were getting insane.


‘We threw the rule book out of the window’


Also worked very well for the Oceangate Titan submersible.


> “brake rotor stud holes may crack and allow the stud to separate from the wheel hub.”

Possible

While mechanical failures can happen in all companies, that do sounds like an inexperienced design (maybe from Tesla, maybe from a partner?)


I can't find pictures online but I'm assuming since it only affects the 2wd and it says if the rotor cracks the stud might leave that the rotor is also the hub.

Doing a half baked job on a part for your super low volume "we only make this to advertise a low starting price" model is something just about any OEM would do.

I bet their supplier just took whatever Chevy Van rotor they had that was close and modified it to fit and as a result it got a little thin somewhere.

Edit: Nope, I couldn't find a picture but I found pictures of big brake kits for the 2wd and clearly it's not an old (read: cheap) integrated hub and rotor.


A 23 year old startup.
