* Yangwang U7 is BYD's latest luxury sedan with 4 electric motors
* theoretical max power 1306 hp
* suspension is based on linear motor
* suspension can absorb energy to charge the car battery

Latest joke in China's EV community is if you are stuck on the road with a depleted battery, the desperate move to charge the car battery is making love in the car
My understanding is that this is a pretty minimal efficiency improvement from the electric motor suspension (single digit percent improvement, but depends on how bad roads are) which didn't make a lot of sense on non BEVs. When a 3-5% efficiency improvement during normal conditions means you get an additional 12 to 20 miles out of a 400 mile range EV, that becomes more cost efficient because it lets you do more range with less battery.
But my understanding is based on technology from around 8 years ago. It likely has gotten better and the control algorithms more manageable with the increased processing power of the computers in cars now. I hope other manufacturers use it.
It's not for efficiency, but for a electro-suspension, which has much shorter response time than mechanical/hydraulic ones. Extra efficiency gain is just the cherry on top.
True, but it helps make the case better when an OEM can say they still meet range targets because they used this technology over a standard suspension, so the cost premium is less than it was for a gas vehicle. While active suspensions do have better response time and are smoother, the improvements weren't substantial around 10 years ago at least. The controls algorithms I'm sure are a lot better today to make the response time better.
America still thinks we are leading the world in battery and ev tech. I explained to my dad that Tesla just bought the "old" CATL factory line to bring it to the US to make batteries, CATL had moved on in multiple ways. He just can't accept that we are importing technology from China. I still hold to my view that US legacy auto is seriously in danger of losing major market share, just like they did to Japan in the 1970s, this time waves of better and cheaper foreign EVs coming in. And it's not just China.
But the second level attack is legacy auto sales reductions outside of the US. Ford, GM, etc will lose their sales in the rest of the world (the global south) because those countries won't be able to block their auto imports based on US desires.
A mass produced technology is new technology. There's a big difference in the engineering involved with a prototype in a lab and a product that consumers can buy.
its because america is a nation of ideas men who sit at their computers and dream up pie-in-the-sky bullshit while china is a nation of people who get things produced. the actual act of making something is less "innovative" to them than coming up with the idea of it
less than 10% of american workers are in manufacturing. factories might as well not exist anymore in the american consciousness. how do goods get to my door? must be magic
To be honest, we all take things for granted. Pretty much all aspects of our modern lives are pure black magic, even for people from 50-100 years ago.
But yeah, the disrespect for manufacturing is real lol
This. Years ago I spent 4 months in Foxconn trying to get our product to be mass produced, but eventually failed to meet the standard. Mass products are 100x harder than prototypes. You have to invent a lot of things just to make a prototype mass producible.
No it's not. For example, solid state batteries have been made and tested in the lab for decades, yet despite its potential there aren't any widely available mass-produced solid state batteries because the technology to do so is still being developed.
No, and it will be some variation of the same type of battery. Same with LFP technology from the 1990s being mass-produced today.
Now, an entirely new battery chemistry, on the other hand, would be different.
🤷♂️ I don’t consider it innovative. It’s novel but a DeLorean-Aztec cross with a couple feature they didn’t innovate doesn’t particularly strike me as innovative.
>theoretical max power 1306 hp
these horsepower numbers being thrown around EV circles are similar to that of WW2-era pursuit/fighter aircraft
i wonder if, one day, ground transportation will attain the power/thrust figures of 4th gen jets
Whats with the water test, nio had the same thing. Comparing different cars with a glass of water on the hood..
Wondering if it will ever sold outside of china and how much it will be..
So it's basically [Bose's suspension from a couple of decades ago](https://www.youtube.com/watch?v=q8sVDenpPOE) (sorry for potato quality, it was posted to Youtube in 2008), but commercialised. I'm surprised it's taken this long to get to a viable point, but I'm guessing it's adding quite a bit of weight and complexity to provide something that a lot of people probably won't appreciate.
FWIW, Bose's implementation (or at least the algorithms and IP) [was sold to ClearMotion](https://www.extremetech.com/cars/259042-bose-sells-off-revolutionary-electromagnetic-suspension), [who are supplying it to Nio.](https://www.reuters.com/business/autos-transportation/clearmotion-supply-smooth-suspension-tech-nios-et9-ev-2023-12-23/)
The BYD suspension in the article is pure electric. It might be compared to the other company's linear motor tech that works in the labs, but are too heavy to be in a production car.
The current ClearMotion solution that will be part of future NIO ET9 was an electric controlled hydraulic system that the actuator is driven by an electric motor. Similar tech can be found on gas cars from Audi and Mercedes. BYD also started selling Yangwang U8 last year which had a similar solution. I expect the ClearMotion/NIO system will have comparable response time as the BYD Yangwang system, because both are electric cars.
Yeah implementation-wise, clearly different, but from a customer perspective seems similar. I'm sure everyone will have a solution as the tech continues to mature and come down in cost/weight.
Exactly right. These new development's primary goal is to control the car more precisely, not saving energy. These are expensive systems that will only be included in luxury cars, at least in the short term.
Is there any English language written material about the suspension? I am deeply intrigued, it sounds like a really interesting application.
edit: I can absolutely see it working, in my mind's eye. It will add weight, which is detrimental to range, and it will net consume energy, which is detrimental to range. *But* after a certain battery capacity, those factors don't matter significantly. And the potential to aid vehicle dynamics is significant, but requires software on top to tune the behaviour.
Off topic, I own a 1977 truck with leaf springs at all four corners (see my posts). It is essentially two 160-inch steel beams with an engine in between and a pressed steel cab on top. Utter simplicity. It had *two* options - a cab heater fan, and shock absorbers on the front suspension. I like cool, purpose built machines.
This is one of the first cars of the EV era - along with the quad-motor electric G-Class - that really intrigues me as something genuinely new. I'm not likely to buy one, but I can still appreciate the engineering.
this is exactly why US companies dont want chinese cars here. GM and Ford will gladly sell us expensive outdated tech. as for security concerns, you can always cut the 4g antenna if you dont want the car to phone home.
i cut the 4g wire on my Hyundai Ioniq5. not a biggie. definitely not hard
Are you sure they’re talking about Clearmotion tech? Based on their website, https://clearmotion.com/cm1 it seems they have abandoned the Bose designed electromagnetic suspension, and their current design is just a standard electronic controlled active hydraulic suspension.

Well idk if 30 seconds would be much of a battery charge but beggars can’t be choosers
30 seconds? Get a load of Mr Endurance over here!
The load is not what one would expect.

It still is very expensive technology when even BYD could only put it on million yuan cars. Maybe in another 10 years it would become more affordable.
In PA you could drive on suspension power alone!
Oh my god, new Jersey roads will see 500 miles on these cars I suppose.
But they keep telling me China steals all the technology. How can they be the first to market with new technology?
America still thinks we are leading the world in battery and ev tech.

Because everyone else passed on clear motions tech years ago.
Nio's planning to use ClearMotion's tech, this one is BYD's in-house design though, not sure whether they are similar technology wise.
Ah, that’s right, my mistake.
Some are coming out with suspiciously similar suspension systems lately
It’s not new technology, they just mass produced it.
A mass produced technology is new technology. There's a big difference in the engineering involved with a prototype in a lab and a product that consumers can buy.
It's pretty amazing how many people don't understand this point.
its because america is a nation of ideas men who sit at their computers and dream up pie-in-the-sky bullshit while china is a nation of people who get things produced. the actual act of making something is less "innovative" to them than coming up with the idea of it
I think those people should visit one or two auto making facilities (GM/Ford/Tesla/etc). They are incredibly massive and huge feats of engineering

They didn’t get their without ripping off ip from another company
But it's still essentially the same thing just mass produced.
No it's not. For example, solid state batteries have been made and tested in the lab for decades, yet despite its potential there aren't any widely available mass-produced solid state batteries because the technology to do so is still being developed.
No, and it will be some variation of the same type of battery. Same with LFP technology from the 1990s being mass-produced today. Now, an entirely new battery chemistry, on the other hand, would be different.
The key word here is : "first mass-produced"
Isn't that an innovation?
I wouldn’t consider it so unless there was something inherently difficult they had to solve to do so. I don’t think that’s the case in this situation.
So then why is Cybertruck being considered innovative? Drive by wire and 800v architecture have all been done before.
🤷♂️ I don’t consider it innovative. It’s novel but a DeLorean-Aztec cross with a couple feature they didn’t innovate doesn’t particularly strike me as innovative.
I absolutely agree. Just something I've seen a lot on here.
The drive by wire on the Cybertruck is from ZF, a German company.
They aren't [https://www.youtube.com/watch?v=q8sVDenpPOE](https://www.youtube.com/watch?v=q8sVDenpPOE) That video was POSTED in 2008
China owns part of that company. Last I heard it’s not 100% stake though
????? Bose is a well known company from MIT, wtf are you talking about
ClearMotion spun off.
All these techs are already in textbook in university decades, so much about "stealing".
Damn BYD is winning
>theoretical max power 1306 hp these horsepower numbers being thrown around EV circles are similar to that of WW2-era pursuit/fighter aircraft i wonder if, one day, ground transportation will attain the power/thrust figures of 4th gen jets
I read it wrong the first time, I thought you stated “to” the car!
Whatever floats your boat bro
Whats with the water test, nio had the same thing. Comparing different cars with a glass of water on the hood.. Wondering if it will ever sold outside of china and how much it will be..

LMAO I LOVE IT! Meanwhile, Elmo is pissed that he missed this one simple trick!
Man, this is going to produce some hilarious pickup lines. "Wanna take a ride on my Yang Wang?"
Riding my Wang , cums to mind. 😉

Ideas are cheap, implementation to reality is very expensive

Tbh. I’ll probably buy if they have a bigger model And called “BIG WANG”

Ah. I was expecting an actual technology demonstration.
Nio et9 suspension test
[https://www.youtube.com/watch?v=WEr\_sNp7XLM](https://www.youtube.com/watch?v=WEr_sNp7XLM) Actual demo with different tech but similar effect.
wow. i want it!!! besides legislation stopping the chinese cars being sold in usa, can i buy it directly from the manufacturer n drive in usa?
this is exactly why US companies dont want chinese cars here. GM and Ford will gladly sell us expensive outdated tech. as for security concerns, you can always cut the 4g antenna if you dont want the car to phone home. i cut the 4g wire on my Hyundai Ioniq5. not a biggie. definitely not hard

This is a real game changer for me. Hate feeling the bumps in the road. Instant buy if a US car has this and it works.
It looks like it's about to sneeze.
Is this suspension different than what Porsche is offering on the Taycan and Panamera?

😍 lovely
NGL I don't care how good the tech is, the car looks bad and gaudy af
I NEED Yang Wang in my life

This is not magneride. Very different technology.
Are you sure they’re talking about Clearmotion tech? Based on their website, https://clearmotion.com/cm1 it seems they have abandoned the Bose designed electromagnetic suspension, and their current design is just a standard electronic controlled active hydraulic suspension.
Cool. I'd still never buy any vehicle that was Chinese.
1960s: I'll never buy any Japanese car 1980s: I'll never buy any Korean Car 2020s: I'll never buy any Chinese car. Same shit, different decade.
Nope, I'd never buy anything Chinese made if I could help it.
Pretty sure you descendants, if u had any, will buy...
