Well said, ...although perhaps technically "with minimal losses" might be more accurate, but simpler can be better. I also added a comment not having seen yours first, and your wording is more concise than I came up with!
A reason induction motors are used as a second motor is that they can freewheel without producing voltage that the inverter would need to deal with, so can be disabled as necessary to improve efficiency
Great video. A couple of points, 1) almost all dual motor EVs use an induction motor secondary axle, as it allows very low drag when that motor is not being driven, allowing a reduced loss of efficiency from adding another motor. The other option being to add an extra clutch system to enable disengaging the secondary motor 2) radiator not only for cooling of battery but also passengers :)
Thanks for the input! Yep, to be honest I don't know a lot about electric motors, I just know what they are in the different types. Not the engineering philosophies behind which one to put in a car!
And why western continue to spread “poor quality”, “forced labor”, “unsafe design”….. lies to convince american why no Chinese EV is allowed to enter the market.
It all looks so clean, very little wires/hoses. All in modules. Their cooling/heating control valve straight out of Tesla book supermanifold and it is a good thing.

BYD AU having a 4-day sale 14 Nov, 15, 16, until Sunday 17 November 2024 ($4,000 discount - $3,000 price reduction and a free $1,000 home wall EVSE unit)
This 8-in-1 concept I saw already in 2019 when I sneaked into BYD sales meeting in a nearby hotel. It was after 5PM so they were basically hanging around and checking out the large photos and talking about their plans. I saw they had talked about how many factories they were going to build and how to expand the product line upwards to compete with Audi and Mercedes. After that they have hired tens of thousands of engineers so who knows what they are up to. One thing that I noticed was that the manufacturing efficiency was marked #1 (with high quality). What made me giggle was "We will first beat VW in China and within 10 years in the whole world." That is not a laughing matter anymore. VW has more than 200 factories so think about how big BYD needs to be and how small VW has to become.
@@unclezeppy well they have beaten VW in China. VW was the highest selling brand in China for 15 years, BYD has taken their top spot in China for the first time this year.
That a Japanese company specializing in analyzing and dismantling electric vehicles should express itself in terms of praise for a Chinese manufacturer, such as BYD, is an honor for BYD and a recognition of the professionalism of the Japanese company that dismantled the car.
That's hard since almost all supply chains are in china locally and BYD produced almost all spare parts in house, last time I read it's about at least 70%
All this reminds me of the 70s when japanese cars started to improve automotive technology, copy then improve, then dominate world markets. It took a while for people to realise and for legacy manufacturing to catch up, but they did and it raised standards for all of us.
@@tld8102 each control different electronics. A standard ICE has many ECUs to control different car electronic systems. They have a PCM, ECM, TCM, BCM, etc., etc. Tesla condenses all these ECUs into 5 units, BYD condenses them down into 3.
Short answer I think is yeah you are right. However, it's a balancing act between redundancy + stability with other benefits: - Reduction of production cost due to stream line manufacturing process. I can imagine with this design, all other BYD vehicle can share these same ECUs. - Reduction of cost for software development and maintainance. Since the hardware - ECUs - to control doors, aircon, ... is the same, it's much easier to use the same piece of software across all cars as well. Previously traditional car manufacturer source their components from 3rd party, with different ECUs hardware, different communication protocols, and it complicates their software and varies between cars, even in the same model since some have heated seat/sunroof and whatnot. - Reduction in weight, space consumed for the housing, cable routing also help further reduce cost and improve range, which is essential for EVs I think as long as these ECUs are easy to access, cheap to buy for replacement, and smart design to separate the board for critical functionality, it would still can be very much stable and serviceable. The electronics in cars now going the direction of phones and computers are all going and I dont think that's a bad thing.
It is a tradeoff in the design. You can have an ECU but then it still needs traditional wiring to and from the devices and sensors that it interacts with. Given the circuit boards seen within the inverter drive units on the video, I suspect some processing is done onboard, so it's probably rather more than 3 ECUs if you count those. It may be a matter of bringing signal and control wires to the closest control module and using network communication from there, as opposed to the traditional approach to have one for the engine, another for the transmission, another for ABS and stability control, another for entertainment, another for body control (lighting, switches, wipers), etc.
And here's my issue with it, i think the way its build doesn't matter cuz if japan makes the same car, byd seal, it would still cost twice as much, it comes down to the fact that China owns the supply chain, they make down to the single screw in house, hence why they may exceed China in technology but they will never be that cheap.
Except Japan simply cannot make the same car by themselves, the infotainment system alone, they cannot, not to mention the battery and some others. Even if they could someday, it will be 3 or 4 times expensive, and the Chinese would be more advanced then.
Quite interesting how every western, japanese and korean auto maker had purchased Chinese cars to drive and be stunned by the level of quality and finesse. Even Musk has admitted that the level of sophistication and complex engineering that the Chinese have acheived pales in comparison to any previous human advancement. So the world should be prepared to keep buying new Chinese technologies and stripping them down to be in awe. Forget about catching up..... that's all I can say.
All those electronic items! Of course integrating them into one bigger unit is cheaper for the manufacturer but if it fails is it repairable or has the whole unit to be replaced. From a simple concept like using a battery to drive a electric motor or two to this. Definitely not a car to keep beyond the warranty period.
@@FairladyS130 it'd be expensive part to replace if it was any other manufacturer. But BYD is different in that they actually manufacture the circuit boards. No other maker does that and therefore no other can provide them at the cost that they do

The evidence that these will last already exists. We are looking at this from the wrong perspective, these aren't 'cheap', these are what cars should be priced at. Legacy auto makers just want us to think they are cheap so they can justify their ever increasing prices on cars and parts.
12:20 that’s assuming the side impact point is low enough to involve the floor of the car. In side impacts higher than the floor it will make little difference
Nah it works well in the T bone side impact tests as well. The floor doesn't crumple, so even in raised side impact, ie an SUV side impact, the b pillar is anchored to that solid floor and didn't crumple in as much.
The idea of using multiple control units instead of one centralized ECU box is not a new concept. I know of at least one big manufacturer, Mercedes-Benz that has been doing this for many years now. As early as 2007, their vehicles have used SAM units (signals Acquisiion Modules) in various parts of their cars to control lighting, lift gates, fuel pumps, door locks etc. Example, back in 2007, the W164 and X164 models had a Front SAM and a rear SAM to control various body modules in the front and back, along with a separate ECU, diesel models also had a separate CDI module. By the way, these controllers are not all called ECU, only the engine controller is the ECU, the others are what they call body control modules, BCM's, or as Benz calls them SAM units.
@andrewallen9993 indeed. In fact are these components available at all? Chinese manufacturers have a reputation for non existent supply chains, in the UK at least.
Japan and the west didn't expect this day to come when they have to learn from the Chinese car manufacturing. They were laughing with their eyes closed until when they reopened their eyes, the world of automobile has changed.
@@glennjv01 I'm interested to know too but I myself know little in the subject (aside from the numbers). EV Fire Safe would be the best source of material and data on it though.
Volvo is already a step ahead. Atleast I think so since they have moved on to Central Processing Unit in their latest EX90. Probably have a few of those decentraliced boxes anyway. But most of the work is being done with just one big processor from Nvidia 😊
BYD's main ECU is driven by a Qualcomm Snapdragon SOC. Give it a year or 2 and I reckon all the Chinese manufacturers will just run off 1 main ECU powered by Nvidia, Qualcomm or something similar and they will be used across all cars in their range. It's the logical next step of manufacturing efficiency.
I know for cost/weight savings thy went with a plastic undertray. But for increased safety(??) or battery protection (??), they should at least at least have used a thin gauge aluminum or better yet, steel undertray? Potential aftermarket business opportunity? That said, perhaps a metal undertray would trap more or less heat a plastic one?
Місяць тому+4
The high level of integration reduces production costs. But what about ease of repair?
I would think you can still easily access circuit boards and other components - which the video shows. It's more about compactness and weight reduction by having less boxes (perhaps not optimally designed if they're from third parties) and the connections between them.
And again, that's what makes this special. None of those components are made by third parties. BYD makes everything, all the circuit boards, all the cables, everything.
@@BeYonD-EV will BYD sell parts, or they only sell a big chunk of it? We don't want it to be like laptops or phones if something breaks we toss the whole thing.
the answer is, the less number of components = the pricier to repair as everything gets integrated into bigger units, if anything minimal fails in that bigger unit, you will have to replace the whole unit same for giga casting, any reasonable accident scraps the car
It does, if you want something that people will buy, something that meets today's market expectations. People want heating, and airconditioning, and power windows and locks. And it needs the safety equipment - ABS, airbags, seatbelt pretensioners. All wheel drive can arguably be skipped but not if you ask people who live where it snows. Simple suspension systems won't have the combination of ride quality and grip and steering precision expected today. You can build a simple golf car, but it won't meet safety standards for road use, and it won't meet consumer expectations.
BYD also have SUVs based on this platform I think. That should work better I think. There’s this super rich Chinese car reviewer called ”DCar” or something that they did a high temperature gravel road test in Chinese desert. Hard to understand because it’s all Chinese but man it’s very comprehensive!
bit of a flying visit tot he inside of the BYD Seal but interesting to see nevertheless. A bit scary how much high tech is in there - could we ever go back to a simple car given today's regulations and could someone somewhere turn them all off if they take against us?
BYD has also developed and manufactured their own type of battery called the blade, claiming to be both structural and compact vs other EV battery manufacturer's. it's not a case of china copying other manufacturers' tech anymore.
So.. things that worry me 1) Having no floor between the battery and the cabin means that when the battery goes into thermal runway, you will have about 5 seconds to get your family out of the car before they are barbecued. Not easy when the baby is in a car seat in the back. You wont have much longer with a metal floor, but maybe long enough. Also, if its just off gassing, then at least a floor will protect you from the torrent of toxic vapours a bit. 2) China has some of the worlds lowest safety standards, and this will come out with a product like this which is more concerned with profit than public safety. Life is cheap in China, so dont expect them to do more than the bare minimum to try to save yours when something goes wrong with this car. Theres a reason its cheap (and it's not just "clever innovative manufacturing "). Although I agree that it should be studied and emulated. 3) having the battery as a strucural component in a crash scenario is truly horrifying. It would only take a small deformation in the battery case to start a thermal runaway and we know how that ends. 4) canbus is specifically designed to distribute multiple controllers all over the vehicle. If you think back to what we had before canbus, it was wires going from eash switch to each lightbulb and motor etc. So miles of heavy wires to all of the components. Canbus did away with this with a few main controllers chatting to each other and then to the components controller. Its basically an ethernet to control stuff and a backbone of heavier power wire. 75% less wires. This Burn Your Driveway car with less ecus will be doing away with that and moving back to an older model of wiring, as far as i see it. 5) its fine them being cheaper right now, but what happens when they drive European manufacturers out of business and then overnight get 1000%more expensive. Remember, China are NOT our friends. They are classified as a nostile government by most countries (apart fron north korea and putins russia). Nothing wrong with trading with them but NEVER trust them. 6) what safeguards do you have against then stealing your personal sensitive data (banking etc) when you have your phone connected to it, and what malware / spyware will the Chinese government put in the cars infotainment system ? Would not put it past them to have a kill code they can send to it, so the car stops working whenever it suits them. Could be used in a cyberattack scenario etc. The uk govt refused to use chinese tech in our mobile phone system as thet did not trust chinese not to put in back doors and spy/mal ware in them for critical infrastructure. 7)putting fewer bespoke components in a car isnt necessarily a good thing. If the one single combined ECU 5hits the bed and has to be replaced, then you can bet it would be more expensive than 1 of 10 smaller ecus. Yeah, right now BYD might offer the one combined unit cheaper, but what will the incentive be to keep it cheaper when they have reached their goal of market domination? Sudden price hike round the corner, as as they are the only manufacturer of that thing then they have you to ransom..... Some things to hopefully make people stop and think.....
@@rikwhite6337 China is the most competitive automotive market in the world. The manufacturers are competing with each other there and we in overseas markets are reaping the benefits for it. Low cost cars, low cost cars with high quality standards. As for no floor, low safety standards, etc. All already debunked or unsubstantiated. BYD employ 13,000 R&D engineers, scientists and researchers. They know what works, what's safe and what isn't.
@@edhirxtrastrange yeh my bad, I got the levels wrong and didn't normalise it enough. Sounded ok my speakers at home but people have been mentioning the music a bit.
Best solution must bee small electric controlunits, that means low repair cost for the costumer. To asamble many electric unit in one big unit may cost the costumer giant bills in repair and when thing breaks down all things goes down. Only benefit is the production cost is low. Sad to see this development.
A good videeo but...the teardown would be so much more valuable if each feature was given a pros and cons review/commentary, and perhaps looking at what other makers have done instead. This fell short of that imo and has simply become a "wow!" video. A missed opportunity.
This video was only a promotional video from the company that did the teardown. I am quite sure the full teardown documentation will be much, much, MUCH more detailed ... but you have to pay (a lot) for that! The company that did the teardown, is in the business to make money, they cannot give away everything for free.
What's with the videos from China where new BYD like this one, Seal or Tang, are catching fire on the road with no reason just overrheating when driving, not even when fast charging ?
BYDs here in Oz all have LFP batteries that do not suffer thermal runaway during a rupture or a fire. Unlike the Teslas made in the US with Lithium NMA cells fitted, that often suffer catastophic thermal runaway when ruptured or in a fire, causing a giant fires.
I have doubts aboit being the OEM to build everything. So now the OEMs will start making their own sensors?! It's stupid, it's like reinventing the wheel. Another doubt, is aboit the safety in the battery frame, the battery frame will handle all the forces, there is no chassis... Now I understand why they are cheap...
You've got it the other way around. It's not a car manufacturer making new parts. It's a parts manufacturer making cars. BYD started out making electronics first car second. This will be different to someone like Ford who made cars first and tried making electronics second. As for the battery safety, the battery block is a single solid block, all the empty space is filled in. So it's like having a single thick block of metal underneath the car.

We are looking at this from the wrong perspective, these aren't 'cheap', these are what cars should be priced at. Legacy auto makers just want us to think they are cheap so they can justify their ever increasing prices on cars and parts.
Ok wait.😂
Los japoneses haciendole ingenieria inversa a los coches chinos😂, luego dicen que japon tiene la mejor tecnologia?😮
12:20 that’s assuming the side impact point is low enough to involve the floor of the car. In side impacts higher than the floor it will make little difference
Nah it works well in the T bone side impact tests as well.
The floor doesn't crumple, so even in raised side impact, ie an SUV side impact, the b pillar is anchored to that solid floor and didn't crumple in as much.

The idea of using multiple control units instead of one centralized ECU box is not a new concept. I know of at least one big manufacturer, Mercedes-Benz that has been doing this for many years now. As early as 2007, their vehicles have used SAM units (signals Acquisiion Modules) in various parts of their cars to control lighting, lift gates, fuel pumps, door locks etc. Example, back in 2007, the W164 and X164 models had a Front SAM and a rear SAM to control various body modules in the front and back, along with a separate ECU, diesel models also had a separate CDI module. By the way, these controllers are not all called ECU, only the engine controller is the ECU, the others are what they call body control modules, BCM's, or as Benz calls them SAM units.
Great that they've done all that integration for manufacturing but how much are those complicated ECUs if they go wrong?
And when will they cease to be available?
@andrewallen9993 indeed. In fact are these components available at all? Chinese manufacturers have a reputation for non existent supply chains, in the UK at least.
Can the car be economically repaired after a crash?
@chriscardwell3495 in about to find that out. Watch my other video where my BYD Seal got rear ended. I'm going through the repair process as we speak.
Japan and the west didn't expect this day to come when they have to learn from the Chinese car manufacturing. They were laughing with their eyes closed until when they reopened their eyes, the world of automobile has changed.
It very good car.
What happened to copyright, oh copyright when it's done on your objects and designs.
How would u rate the tech and safety overall ????
google it dont be lazy
A real radiator cooling the battery? I like to break that open water and electric
. Also why it has 10 minute charging to 80%
800V architecture -- similar to Lucid and Hyundai/Kia as well as different cell chemistry which allows faster charging within battery management
please cover why EV hybrids are prone to Fire vs even ICE and pure EVs
@@glennjv01 I'm interested to know too but I myself know little in the subject (aside from the numbers).
EV Fire Safe would be the best source of material and data on it though.
Complex heavy and combine the worst attributes of both technologies is why.
Volvo is already a step ahead. Atleast I think so since they have moved on to Central Processing Unit in their latest EX90. Probably have a few of those decentraliced boxes anyway. But most of the work is being done with just one big processor from Nvidia 😊
BYD's main ECU is driven by a Qualcomm Snapdragon SOC. Give it a year or 2 and I reckon all the Chinese manufacturers will just run off 1 main ECU powered by Nvidia, Qualcomm or something similar and they will be used across all cars in their range. It's the logical next step of manufacturing efficiency.
So far so good that they didn't find any spy cameras that threaten national security lol. That's what they are looking for! 😂
I know for cost/weight savings thy went with a plastic undertray. But for increased safety(??) or battery protection (??), they should at least at least have used a thin gauge aluminum or better yet, steel undertray? Potential aftermarket business opportunity? That said, perhaps a metal undertray would trap more or less heat a plastic one?
The high level of integration reduces production costs. But what about ease of repair?
I would think you can still easily access circuit boards and other components - which the video shows. It's more about compactness and weight reduction by having less boxes (perhaps not optimally designed if they're from third parties) and the connections between them.
And again, that's what makes this special. None of those components are made by third parties. BYD makes everything, all the circuit boards, all the cables, everything.
@@BeYonD-EV will BYD sell parts, or they only sell a big chunk of it? We don't want it to be like laptops or phones if something breaks we toss the whole thing.
the answer is, the less number of components = the pricier to repair
as everything gets integrated into bigger units, if anything minimal fails in that bigger unit, you will have to replace the whole unit
same for giga casting, any reasonable accident scraps the car
@@bauboni Giga casting means you walk away from the bigger accidents. not carried away on a stretcher or worse. So it has its advantages.
Every car maker does this behind closed doors.
Take a step back and think about it folks. Its just a car. A capsule to get you from A to B. It doesnt need to be this complex...
It does, if you want something that people will buy, something that meets today's market expectations. People want heating, and airconditioning, and power windows and locks. And it needs the safety equipment - ABS, airbags, seatbelt pretensioners. All wheel drive can arguably be skipped but not if you ask people who live where it snows. Simple suspension systems won't have the combination of ride quality and grip and steering precision expected today. You can build a simple golf car, but it won't meet safety standards for road use, and it won't meet consumer expectations.
I just can't unsee the low profile tires, if i drive it in my home town Borneo island it'll be destroyed within 2 weeks.
BYD also have SUVs based on this platform I think. That should work better I think. There’s this super rich Chinese car reviewer called ”DCar” or something that they did a high temperature gravel road test in Chinese desert. Hard to understand because it’s all Chinese but man it’s very comprehensive!
DCARSTUDIO
bit of a flying visit tot he inside of the BYD Seal but interesting to see nevertheless. A bit scary how much high tech is in there - could we ever go back to a simple car given today's regulations and could someone somewhere turn them all off if they take against us?
Great video explaining how BYD has copied the true leader in EV's, Tesla. For a real analysis look to Munro.
Its a nightmare to change those rubber bush.
Tesla missed the mark by not making an afordable car that the world needed
Reverse engineering at its best
BYD has also developed and manufactured their own type of battery called the blade, claiming to be both structural and compact vs other EV battery manufacturer's.
it's not a case of china copying other manufacturers' tech anymore.
So.. things that worry me
1) Having no floor between the battery and the cabin means that when the battery goes into thermal runway, you will have about 5 seconds to get your family out of the car before they are barbecued. Not easy when the baby is in a car seat in the back. You wont have much longer with a metal floor, but maybe long enough. Also, if its just off gassing, then at least a floor will protect you from the torrent of toxic vapours a bit.
2) China has some of the worlds lowest safety standards, and this will come out with a product like this which is more concerned with profit than public safety. Life is cheap in China, so dont expect them to do more than the bare minimum to try to save yours when something goes wrong with this car. Theres a reason its cheap (and it's not just "clever innovative manufacturing "). Although I agree that it should be studied and emulated.
3) having the battery as a strucural component in a crash scenario is truly horrifying. It would only take a small deformation in the battery case to start a thermal runaway and we know how that ends.
4) canbus is specifically designed to distribute multiple controllers all over the vehicle. If you think back to what we had before canbus, it was wires going from eash switch to each lightbulb and motor etc. So miles of heavy wires to all of the components. Canbus did away with this with a few main controllers chatting to each other and then to the components controller. Its basically an ethernet to control stuff and a backbone of heavier power wire. 75% less wires. This Burn Your Driveway car with less ecus will be doing away with that and moving back to an older model of wiring, as far as i see it.
5) its fine them being cheaper right now, but what happens when they drive European manufacturers out of business and then overnight get 1000%more expensive. Remember, China are NOT our friends. They are classified as a nostile government by most countries (apart fron north korea and putins russia). Nothing wrong with trading with them but NEVER trust them.
6) what safeguards do you have against then stealing your personal sensitive data (banking etc) when you have your phone connected to it, and what malware / spyware will the Chinese government put in the cars infotainment system ? Would not put it past them to have a kill code they can send to it, so the car stops working whenever it suits them. Could be used in a cyberattack scenario etc. The uk govt refused to use chinese tech in our mobile phone system as thet did not trust chinese not to put in back doors and spy/mal ware in them for critical infrastructure.
7)putting fewer bespoke components in a car isnt necessarily a good thing. If the one single combined ECU 5hits the bed and has to be replaced, then you can bet it would be more expensive than 1 of 10 smaller ecus. Yeah, right now BYD might offer the one combined unit cheaper, but what will the incentive be to keep it cheaper when they have reached their goal of market domination? Sudden price hike round the corner, as as they are the only manufacturer of that thing then they have you to ransom.....
Some things to hopefully make people stop and think.....
@@rikwhite6337 China is the most competitive automotive market in the world. The manufacturers are competing with each other there and we in overseas markets are reaping the benefits for it. Low cost cars, low cost cars with high quality standards.
As for no floor, low safety standards, etc. All already debunked or unsubstantiated. BYD employ 13,000 R&D engineers, scientists and researchers. They know what works, what's safe and what isn't.
@4:25 if you want to get right to it
Why is the music so much louder than you voice?
@@edhirxtrastrange yeh my bad, I got the levels wrong and didn't normalise it enough. Sounded ok my speakers at home but people have been mentioning the music a bit.
AND I THOUGHT THEY WERE JUST A BATTERY AND A MOTOR,,,
Best solution must bee small electric controlunits, that means low repair cost for the costumer. To asamble many electric unit in one big unit may cost the costumer giant bills in repair and when thing breaks down all things goes down. Only benefit is the production cost is low. Sad to see this development.
Finally, EV's are no benefit for the environment and these design principles make it even worse
BYD will definetly overtake Tesla !!!
A good videeo but...the teardown would be so much more valuable if each feature was given a pros and cons review/commentary, and perhaps looking at what other makers have done instead. This fell short of that imo and has simply become a "wow!" video. A missed opportunity.
We await your non wow video.
This video was only a promotional video from the company that did the teardown. I am quite sure the full teardown documentation will be much, much, MUCH more detailed ... but you have to pay (a lot) for that! The company that did the teardown, is in the business to make money, they cannot give away everything for free.
That drumming music is ridiculously annoying.
@@phoarey the original music on the video was like intro music to a corporate motivational speech
I had to change it 😆
"sin-kro-nee-oss" ??? I think he means synchronous ???
What's with the videos from China where new BYD like this one, Seal or Tang, are catching fire on the road with no reason just overrheating when driving, not even when fast charging ?
BYDs here in Oz all have LFP batteries that do not suffer thermal runaway during a rupture or a fire. Unlike the Teslas made in the US with Lithium NMA cells fitted, that often suffer catastophic thermal runaway when ruptured or in a fire, causing a giant fires.
Bro the music is too LOUD!
this behavior for japan & western they call it study or research. Chinese they call it copy or steal.
omg so much that can go wrong!
3:54 Any EV that doesn’t support Musk is worth considering.
"synchronous" not synchronius!
Come on, copy is good！Don't tell me you have not used copy books to learn writing, and using AI for researching now.
I have doubts aboit being the OEM to build everything. So now the OEMs will start making their own sensors?! It's stupid, it's like reinventing the wheel. Another doubt, is aboit the safety in the battery frame, the battery frame will handle all the forces, there is no chassis... Now I understand why they are cheap...
You've got it the other way around. It's not a car manufacturer making new parts. It's a parts manufacturer making cars.
BYD started out making electronics first car second. This will be different to someone like Ford who made cars first and tried making electronics second.
As for the battery safety, the battery block is a single solid block, all the empty space is filled in. So it's like having a single thick block of metal underneath the car.
Why the incessant music ? !
“Synchronous”, not “sychronious”… otherwise interesting vid.
Should be very cheap and easy to repair, though of course it will never need repairs 🤣🤣🤣🤣🤣
Looks very expensive to repair
