5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.
tesla makes interesting cars, but i wait for the day they stop producing drive units, and start producing wheel drives. Hub motors are definitely the objectively correct solution when it comes to EVs IMO. There are so many more things you can do, and so many more options you're opened up to.
oh and they stop being proprietary garbage, perhaps one day we will get opentesla firmware, as a hack.
I'm curious- how do you feel about the Hyundai/Kia Uni wheel system?
im not super familiar with it, but having skimmed the one article im willing to read about it, it seems interesting, im not entirely sure what it intends to do, but that's a fault of the article for not fucking explaining it lol.
If you have a very concise technical TL;DR that would be very appreciated. I genuinely cannot read the majority of content on the web because it has nothing of actual value to me. Reading documentation that actually explains things and technical papers has ruined me.
Shits all marketing speak primarily these days, i don't care, tell me what it is, and show me a demonstration or a diagram. Nothing more needs to be said IMO.
All I've seen of it is the marketing video that Hyundai released so I was curious if anyone had an unbiased opinion. I did show it to someone I know who works for a competitor and they felt that it seemed really promising, but I don't work in the field so I'm not sure.
ok, to be clear, im not educated in this field, but im a hyper nerd in this kind of shit, so i feel like i have some pre-existing understanding here.
notably, this is a take on planetary gear sets, which are notoriously, gear sets. They're fine. There's nothing weird about them, except for the fact that they reduce on an axial measure, which is really weird but super useful for things like wind turbines.
Functionally, it's pretty clever, the vertical motion is obviously useful, the side to side deflection is also going to be pretty important because nothing is perfectly rigid. I'm curious to know how maintenance is going to go, it might be a bit of a nightmare. I assume it's not that bad though, probably easier than a transmission. Which we no longer have in an EV.
If it can be made in volume, reliably, and for a reasonable price, this is definitely the future. Yeah, i mean really my only concern would be maintaining it. Which im guessing it's just an enclosed gearset in an oil bath, so probably pretty trivial. Just replace the oil every so often (or as per every modern vehicle, throw it out and replace every 100,000 miles or so)
Curious how they're going to seal the enclosure to the environments though, probably a boot, im sure that's going to be equally as problematic as every CV boot ever has always been so nothing new there really.
Thanks for the insight! My uninformed view was that from a moving parts perspective it was a lot fewer than a transmission and traditional drivetrain, so it seemed like there would be fewer points of failure and less complicated maintenance. It also seemed easy to produce, even with tight tolerances it's pretty mechanically simple.
It was hard for me to see if it was just marketing hype though. It's interesting that wind turbines use planetary gear sets! I never thought about it before beyond "wind spin blade= electricity."
I live in the most Tesla filled city in the world. I'm a fucking dick to them. I'm sorry, but if you're buying into that Nazi's cult and I have the choice of being my usual kind self, or taking the opportunity to go ahead of you, cut you off, etc., I'm going to do the latter.
Really? I know a couple of people that had one, and the main reason for not buying another is they're the 90s Alfa Romeo of electric cars.
Looks nice but always at the garage.
The charging infrastructure isn't where it should be if people were really serious about EV.
People are avoiding Tesla's?

That’s delivery of vehicles. Aren’t they famously way behind with long wait times? Actual sales figures would be a better gauge.
I don't think this is having a meaningful effect. Tesla'a biggest marketplace is China, and I doubt they care about American politics. It is more likely that China is discouraging people from buying Teslas due to American threats to ban Tiktok.
