Watching this , as a 59 year old airline pilot… who was once an engineering apprentice! I recall taking the engine and gearbox out of my 1970 M G 1275cc Midget, single-handedly to swap the clutch. Grinding valves and decarbonising the engine. Who knew, in my lifetime, that I would hardly recognise the parts in a modern car? I watch this in awe. PS I collect my MY this weekend 😀😀😀😀

The welds look like to me that they are puls mig. TIG to MIG, MIG is production (fast) TIG gives appearance (slow). How the wealds are not visible on this part, no-brainer. Speed is the name of the game. Puls MIG is perfect for structure. Good penetration an good deposition. Right choice.

Ben has really stepped up his on-camera presence since the beginning.

A scruffy looking weld is not automatically a bad weld. After all, we are not talking about a steam boiler pressure weld.

As one with over 4 decades in the welding biz those welds are fine, room for improvement on a couple of them but far better than most you'll see on production cars.

Space x fingerprints all over these designs. Did not go to school in Detroit.

Great presentation by both once again. Ben has gotten even better and more comfortable presenting in front of the camera, well done!

This kind of cross-model compatibility approach has a lot of synergistic benefits. A lot have been mentioned, but two I especially like are: 1. Allows improvements made in any new vehicle project to easily make their way on to the assembly lines to bring those benefits to other models. 2. Greatly reduces the number of part variations that they need to manufacture, store and make available for service. Just think how many old-style parts from the model S original development project no longer have to be made and stockpiled, now that it shares common parts with 3 & Y.

This is my most favorite channel, maybe because I have a Model S and this is only way to find out how it works because Tesla does not provide documentation on their cars to consumers. :)

I expected a monster bespoke thermal management system for the Plaid! I'm amazed at how it's reusing existing parts, and still getting unreal consistency on the tracks and drag strips 🤯

I'm 75--waiting for my Model X Plaid. You guys are pioneers, leading us from the world of my grand dad's model T and rich men who did nothing but sell parts of our earth to burn and pollute---- to a better world for all. Well done...and SO interesting. Thx.

Always a nice surprise to find a Munro Live video waiting in your YT feed waiting to be watched. Great work guys, hope you will be going to the Giga Texas event next month!

Great video. Couple things: At 17:16, you can still drive it. You don’t “have” to wait. It just means to have peak performance, wait. 18:28, they make about 1,700 Model S’s per month.

20:22 I believe they used the EPDM lines to dampen the noise or vibration transfer from the rest of the system because it's the only unit that is inside the car.

Love the videos! I'm not an engineer, so I really appreciate the parts of the videos when you guys don't use special engineering words and explain methods and concepts in plain english. Love from Austria

The 11Kg saved on the battery is the highlight for me. I hope they can use that in the next model Y, less weight, more efficiency!

A very good episode that is back to the core of what makes Munro Live great. Cory does well keeping the flow of the presentation with some details and Ben really stepped up with the technical information, like the weights, the materials, and the Why. Great job guys and thank you for the video. /cheers ScrapBongo

In my field (high-speed semiconductor design) one of the most power-expensive things we can do is distribute high-speed clocks. Anything we can do to cut down capacitance on the clocks (most often proportional to wire length) pays off in spades. The best designs are those where the circuitry that generates the clocks is close to the circuits where they are used, where both pieces of circuitry are compact, and where everyone paid attention to the wires that connect the two to make sure that they take priority over everything else. In EV's I already knew that the high-current/high-voltage conductors were analogous to my clocks, but your videos have convinced me that the thermal system is an even better analog. As always, excellent content.

Amazing engineering. Whatever the model-----Tesla has dragged ALL the other car companies into the future.

I can't get over how similar the components the systems are from such different models. Ordering/making parts, sourcing has got to be much easier at Tesla than any other automaker. The flexibility is amazing.

What does it tell me when they are able to use so many parts from Tesla model Y or 3 is not only that it is a smart move because of cost savings and so on, bla, bla bla but also that those parts like octovalve are so technologically advanced that they CAN be used - simply able to keep up with the pace and needs of the Tesla Plaid, which must be pretty high. They are not using those universal parts only because somebody has told them to do so. The the whole trick in this is that those components are such a beast that they are probably doing the job the best what the engineers can think of right now. I wouldn’t be much surprised if it was done even the other way round - while working on Tesla Plaid somebody could invent ocvovalve and they could decide to put it also into their lower cost vehicles. Something like steel for cybertruck was originally meant for rockets... Either way, it is just amazing.

Brothers, Just brilliant engineering for producability and cost! Cheers, Eric

this is one of the most educated set of viewers. the comments on this video and channel in general are very informative on top of already amazing content. cheers to all the engineers and trades folks here sharing knowledge!

So did they finally get rid of the need for a traditional 12V battery?! That's amazing! The small Li-ion battery should last significantly longer than the old super heavy Pb-Acid batteries.

For the welds people have to remember that the main thing that matters is that the welds hold up. It does not have to t look pretty, it just have to be structurally sound. Especially when it is under the hood, under a beauty cover and on the bottom side of the unit. You are never going to see it. Why spend time and money making it look nice when no one is going to see it?? I guess since I am an engineer I see it from that point of view

Just imagine a tear down of the Cybertrack, It will a new holiday!

Cory and Ben - I appreciate you two so much! You two show that Tesla vehicles are the best engineered autos in the world.

🤗THANKS CORY AND BEN FOR THE BREAKDOWN in terms we can understand 🤔😍😍😍

Y'all are excellent. I loved your closing thoughts. They had enough foresight on so, so many things for this car, and the structure of their company hierarchy has helped them with thinking ahead, too, so that all the systems work so well together, efficient with cost, weight, and everything else! My thought after this was: man I hope this means parts that are shared with MY will also be cheap to replace on the Plaid and CT, too! No reason one they have engineered mass- market parts for them to reinvent the wheel unless they want to do so!

EXCELLENT tutorial video AGAIN! THANKS guys! If one thing I may say, or request, its this: You guys put SO much energy, effort, time and finances into your work, I think IF the videos would cover less per video BUT would INCLUDE diagrams and closer up-videos (maybe even high quality still pictures) of how the various systems work, were engineered and conceptualized, your videos will be in another league! 20-30mins per tutorial videos, covering e.g. just a part of the Plaid's thermal system BUT with more graphics, diagrams close-ups etc., to explain to all the viewers of whom probably 99% are less experienced than you, what each part does, why it does it and how it does it, compared to other manufacturers etc. would be VERY illustrative and provide s steep learning curve for the viewers. So, e.g. this video, amazing as it is, could be split up into at least 3-5 videos, each 20-30 min. with a deeper dive into each topic, supported by diagrams, graphics and more close-ups etc. I guess that the overall cost for such videos will not be that significantly higher, compared to the overall cost of the Tesla S Plaid project. BUT the OUTCOME, the learning and the importance of your channel (resulting in far more subscribers...) will be immense. However, KEEP on doing what you do, your work and engagement is HIGHLY appreciated and as a faithful learner of your tutorials I am looking forward every week to your new videos.

Just more evidence why the competition is F'ed.

Thank you Cory and you Ben.

My take-away is that if the Plaid is able to use essentially the same thermal management components as the 3 and the Y, then the 3 and the Y have extremely robust systems for what they are called on to do in those cars.

Highlight of the day these strip downs, tons of info,

A great team presentation. Good work on that, guys.

24 minutes well spent - great insight and clear explanations!

Easily the best channel for a genuine, in-depth analysis of a new vehicle. You don't get this anywhere else!

I'll be fascinated to see the differences once you have a chance to tear down a new Austin MY with all of the structural changes from the 4680 integration.

I am soaking these videos up, especially the ones about Tesla. I am picking up a Model X Plaid this Saturday and this and other videos are very informative. I was a design engineer and I am currently a quality engineer in Aerospace and appreciate the engineering.

My father was a heavy equipment repair welder. He would weld and repair giant catarpillar mining equipment and had his own shop repairing this equipment and was known to be one of the best around. His welds looked just about the same. And we’re just as solid and reliable as you could get. He taught me to weld as well and I can say without a doubt that if your complaining about these welds on the model S your a joke. They are perfectly fine. There is no need for fancy “perfect bead” welds. If your complaining about that your out of your mind & I’d like to see you weld 100 of these in one day with picture perfect beads. If you can do that and show proof than I will eat shit. Literally.

Ben is really doing fine nowadays in front of the camera. Super! I thought all Americans were "elevator pitch" guys but maybe not. Well done!

Well thought out explanations and supposition on why Tesla may have done certain things.

Consider a spot at the end for Sandys color commentary and context relative to auto and other mfr sectors

Thank you soooooo much. I love watching it every time.

Awesome stuff, very interesting to listen to the both of you! Thank you.

Nice, indepth and informative teardown guys. Greetings from Ireland.

I am amazed at the complexity of a great EV. It seems almost as complex as an ice vehicle, potentially having same mean time between failures. One major saving grace is far less heat than an ice vehicle. Thanks for showing me what’s in my LR - mS.

Fantastic analysis! A great watch, thank you!

When Cory talks about ribbing the Ford Mach E and its having 4 pumps for the coolant, Ford is listening. Jim Farley, CEO of Ford ..."If I showed you our cooling system for the Mach-E it has four motors probably needs to be two. It has 60 or 70 hoses probably needs to be one-third of that. And those are the opportunities we are going after." This is the information Sandy and the Munro team talked about during the Mach-E teardown. /cheers ScrapBongo

Thanks Corey and Ben--just magnificent work, again on this teardown! So fascinating and insightful. This must be required viewing at every OEM worldwide. All of the time, and work you're putting in to these videos beforehand to make them go so well is very clear, aided by the excellent camerawork and editing. Corey is a natural for the camera; Ben still seems a little uncomfortable looking directly into the lens. Imagine you are talking to a best friend or family member and it will become easier. We're all rooting for you. I'm already subscribed, or I'd do it again!

I love the teardown. I grieve to see that fine car taken to pieces, but you've learned so much. I'm looking forward to a motor analysis of that unique laminate.

Good job guys! Love the teardown. Tesla is doing an amazing job reusing parts. And you are doing an amazing job documenting and concisely sharing this wonder of our lives.

Cory can take his time when moving these parts around, I'm worried he's gonna break something he's in such a hurry. Remember we don't see the parts often, so getting a longer look at them is just fine with me.

Love your work gentlemen- fascinating stuff!

My take on the welds, I work for the navy as a weld inspector.. I think that the fillet size is massively oversized for the function. I think those welds will hold for the lifetime of the vehicle and then 20 years. I can see a few weld attributes that might fail a navy inspection depending on follow on higher level inspections like liquid penetrant and a little weld spatter but frankly i think they are just fine! my concern is the brazed aluminum backing, if its a silver braze, it very easy to have alot of failure points along the entire length of braze as the braze temp has to pretty much be in a 10 to 20 deg corridor and its easy to mess that up(especially with the geometry of the part being so non uniform controlling the temp might be difficult).... I have a model 3 so ill keep an eye on that as time passes, thanks for the insight....

This is just awesome to watch. Amazing level of engineering and hard to reach for the competition. Thank you for sharing!

We missed Sandy’s thorough and enthusiastic explanations! Don’t leave us Sandy

Think of the cost efficiencies that you could achieve by designing and engineering only one thermal system AND hoses that fit every Tesla model.

So interesting to hear super smart engineers taking us thru all the good stuff

Great job Ben and all those at Munro! Thanks for another video 📹

You guys did a great job on the video. Very interesting. Thank you!

Nice presentation guys. Vertical integration has its advantages.

Nice breakdown.

man tesla is freaking impressive the interchangeable parts are god sent

Many years ago i used to read articles in Motor Trend authored by Jean Lindamood. Just wondering if Ben is related? BTW, the Munro Live videos are always interesting and informative. Great stuff.

Kudos guys, your presenting really well thanks

That’s why Tesla “overengineers” their parts and opt out for higher quality and cost components. That way they can reuse them in all their vehicles.

Great vid, thanks. I’d like discussion on heat pump coupling to refrigerant-coolant heat exchangers - what prevents them being mounted on heat pump (close coupled). I’m real impressed they’ve gone this far, minimised volume of refrigerant and length of vulnerable refrigerant hosing. That’s still incredible complexity! I’d like to know if this is applicable to domestic HVAC. It’d reduce installation cost / complexity. EDIT. I watched the untangle club vids. They answer my question peripherally. Wow it’s complex!

Great job guys! Your channel is really high quality and totally unique. Fantastic to examine this paradigm shift in such detail. Tesla cars will be in the market a long time because of the interchange-able parts.

Thank you!

Parts commonality means increased economies of scale. Noice!

Thanks for a good report guys!

Really insightful and informative commentary Cory and Ben - many thanks from an engineering layman

Great explanation.

Thanks guys!

I love how Tesla make car's, in technology aspect, ingenuity aspect, cost aspect they always ahead and thinking forward. Tesla is the future. That's why all of my family members and all my friends have Tesla and ordered more Tesla car's. It's the best and awesome car's to have. We are going to Austin Texas so see the Tesla giga fest.

great work as always. gets even better as you have more teslas to compare to eachother 👍

Really enjoying the channel 😊

WOW. What amazing engineering. Particularly when compared to the Mach E Mustang, which illustrates how far Ford needs to go to compete. I am, as usual, very impressed with how y'all have figured out how it all works. Kudos guys.

I especially appreciate seeing the parts commonality among the Tesla models as this speaks to the overall efficiency of Tesla's production.

Wow… You guys are amazing! All of you would definitely be a great asset to an EV company ⚡️👍

Great video Ben and Cory. Ben is becoming quite the star. Well done. Great to see Tesla's forward thinking approach to engineering.

Amazing content. Always a good idea to share why a component makes good practice (or is bad design) I am sure most of us watching need it spelling out as normal people do not get this close to dismantling a car.

"Thermal System Breakdown" What an excellent thumbnail. I like the unintended double meaning.

Outstanding video as always. To a regular person, seeing a Tesla vs another EV, Mach-E for instance, they only see "two cars that are both EV's, vroom vroom." To anyone who cares to pay attention to the real technical differences they see a car, Tesla in this case, that is light years ahead of the competition and, when OEM's get their act together, these components will become the new norm, granted Tesla will already have moved on to innovating the next greatest thing.

You're talking about how the present (whatever) for the Plaid is somewhat different than what is on the Y. What you may be missing is that the Model Ys coming out of the factory today share the exact same parts as the Plaid. You are looking at a Y from the past. Tesla makes changes daily. (You know that.)

Another excellent video. Indeed it was treat :-)

Y'all need to actively search for an inside source at Tesla that would be willing to give an opinion on the critiques offered up in these videos. It would be interesting to get the feedback, and i'm sure there are enthusiastic internal engineers willing to give non sensitive commentary. My guess for those cheaper lines, may be the whole supply chain shortage issue. Same way they've been substituting chips to maintain output, they may have also had to substitute other components as well.

Great video. Keep up the good work guys!

The welds are fine structurally, and that is what really matters.

Fabuloun engineering design analyses and presentations by Ben and Cory. Thanks for the user who provided 2 URLs explaining the octovalve (parts 1 and 2). Another comment below stated that there are 13 variables that are use to control the octovalve.

Keep the information freight train rolling! Great job everyone.

These are definitely MIG pulse welds. Can be recognized quite well by the black deposits in combination with the "cold weld" at the beginning and covering of the end grater, all with the few weld spatters.

There was a question on LR vs. Plaid as far as the extra two external coolant pumps. I can confirm at least one of the pumps (not mounted to the manifold) resides in the 2022 LR. I couldn't find the 2nd one, but without ripping it appart, the 2nd pump may be there as well. Oddly, I was unable to find either pump in the Tesla parts catalog, but I've noticed other occasional parts missing from the current catalog. Thanks for the great teardown!

I appreciate some of this engineering elegance.

Totally worth the $20 sticker. Love this stuff.

Word of the day " Space Age technology " .

Good job chaps, keep it up ... its fascinating.

been waiting for this one.

I use to spray aluminium paint on the mig weld for the appearance.
