Вставка
- Опубліковано 8 чер 2024
- Tesla never sits still. It's always innovating. Even when it comes up with an elegant engineering solution, it's not satisfied--it always wants to make it better. Terry Wiychowski, the president of Caresoft, takes us on a tour of several design evolutions that provide great insights into Tesla engineering, including:
* steer by wire
* 12v, 16v & 48v auxiliary batteries
* cross car beams
* aluminum charging wires
* air suspension tanks

Tesla engineers pursuit for efficiency just blows me away when you see videos like this!
It's a mindset and culture change. I hated in the past people saying things cannot be done
@@mariuskoen1 lol tesla=trash engineering
@@mariuskoen1 Get the bean counters out of directing auto industry engineering!
Bean counting is very importend!Changing things to fast is also very costly and will be a problem with spareparts in the future!
Sandy Monroe said when he worked for Ford back in the 80s, the engineers wanted to switch to a 48 volt system.... but the bean counters killed that idea.
What an awesome presentation. I love that the stations were setup elegantly you walked the circuit in order. Nicely done and explained.
John please continue these visits with Terry and Caresoft. These deep dives and Terry's knowledge are so fascinating to hear about. The thinking of Tesla and Legacy automakers couldn't be further apart. Tesla really is thinking about car construction in a completely different way. Seems like the gap that the Legacy automakers need to bridge to Tesla is a near impossible one if they don't really re-evaluate their old ways.
We can see here the result of Tesla's MobAI approach. A mob of, say, 12 engineers working a 12 hour shift trying to optimise a component to be 1g lighter, 1c cheaper, 1 second faster to make or to draw 1mW less power. It's well worth watching Joe Justice's videos on how Tesla powers through this accelerated evolution is a crazy short time.
You actually believe this bs? You really think Tesla is ahead of the many far more advanced established car manufacturers? Have you not even glanced at videos on Tesla's production and how stone-age it is compared to even the most cheap products of established manufacturers?
Haven't you heard about how established manufacturers have reached near-zero-waste production and sustainably powered production (even for their most cheap cars) while Tesla only publishes fake images with solar panels on their factory roofs which aren't really there, and chuck half a car's worth of waste out the side door every few hours?
Tesla's production line is a dirty mess of scattered cardboard boxes and plastic bags, with employees marking things down on paper lists...and Elon points the interviewer to a robot carrying parts around...which is all scuffed and battered because he got it used, as it's something all manufacturers have used before Tesla was even founded ne it probably came with his purchase of the Toyota factory.
@@garyrooksbyYou sound really excited...but not too clever. What do you think other car companies do? You think they only have 11 engineers? Doofus...
Love seeing John like a kid again
Aux battery evolution was a spectacular and unique demo, deserves its own video release.
actually not! BMW was one of the first to use lithium as aux/crank batteries long time before tesla! there are videos of teardown on internet too.
@@alanmay7929 yes tesla often not the first but they mass produce and standardise across the fleet. bmw is still using 12v in almost everything
@@gazlives bullshit! other manufacturers actually mass produces not the crap youre talking about! bmw actually is using both 16v lithium and other battery like lead... i dont see where the problem is!
@@gazlives EXACTLY! Tesla scales and optimises like no other. They don't care whether they invented something or not. They open source all their patents anyway. They're happy for other OEMs to steal their homework as they're always continuing to optimise anyway so they won't catch up.
Kinda funny on the air line for the battery pack ... since Tesla has explained their wade-mode. No need to be puzzled on that one.
Hindsight is 20/20
@@alex135789 This information was out prior to the tear down.
@@JT_771 My bad. I wasn't aware of that.
I love these Autoline videos with Terry at Caresoft. Terry and John do a great job, with Terry's extensive engineering experience, and John's enthusiasm and vast general auto industry knowledge. I can't wait for the upcoming videos on the Cybertruck 48 V system and battery pack.
Excellent program. Between this and Munro teardowns I learn so much detail and innovation especially from Tesla but also how they compare to other OEMs
35:00 the line going to the battery pack from the air reservoir is absolutely to pressurise the battery pack if you are going into deep water - eg crossing a river.
Wow , great layout , and I love listening to Terry articulate all the specifics . Great show .
Really nice presentation. High voltage battery discussion is eagerly anticipated.
John you always ask the right questions !
John has experience, is knowledgeable and interested, that shows in the videos..
I saw in a video that there is a dashboard setting button that allows the driver to set the vehicle for water fording. I believe they said it was indeed to provide positive pressure to the battery pack to help keep water from intruding.
This is an excellent video, clearly showing the difference in design considerations.
This gentleman is more like a professor than a businessman. Compared to the other better known Tesla teardown channel certainly less 'entertaining' but so much more enlightening. Instead of throwing out jargons only they understand, everything is laid out in context with common and thoughtful language. Thank you so much for the presentation, I'll look forward to more of your 'classes'
Well said!
Excellent videos. Keep em coming and I'll keep watching!
Me too !!! I'll keep watching.
How do you know these videos are excellent? Have you seen an actual expert evaluate these videos? Have you seen criticism of these videos, any benchmarking?
Tesla is the best car company ever! No gas stations, No oil changes, No smog check, No corrupt dealership, No catalytic converter and as fast as a $650,000 Lamborghini !
What??!! here in Europe them Teslas only go 120 Km/hr tops, or they will be impounded, and the driver losing the license; so, for that a 30 year old 200 euro only, Fiat uno is a much better car
These artificial/arbitrary specification requirements of Legacy OEMs are going to be the death of them and clearly nothing Tesla in particular is worried about when they're making their Cross Car Beam that's way more elegant and efficient in every single way.
bullshit!!!! other manufacturers actuallt builds solid cars that have been used in the most harschest environments on earth! that cybertruck is pile of junk compared to a 30 years old toyota hilux! the offroad test alone shows it! lets not talk about the old hilux been overloaded for decades moving people and goods on almost not existant roads! all that plastic in the dashboard.
The cycbertruck function of pressurizing the battery pack is called Scuba mode for off roading. A Tesla head engineer talked about it on the Jay Leno Cybertruck review.
This room is beautifully set up, it was a pleasure to watch this.
It's always interesting to see people from legacy auto take digs at Tesla and watch them overtime become real fans of their achievements
It’s my experience that people don’t hate Teslas. People hate Tesla owners.
@user-vx7vi3vq1c only the pretentious ones, and they are not the majority
@@jtkstudios4168 you’re probably right. So many Tesla owners I’ve run into suddenly become car experts. A three minute conversation shows the contrary.
@user-vx7vi3vq1c the same can be said about those that hate Tesla. The fringe people squawk the loudest, especially online.
Experience, education, and understanding goes a long way
@@user-vx7vi3vq1c
I wouldn't say hate, more like jealous... but then again jealousy always leads to hate.... So yeah you're probably right.
Its funny you can host one show that have folks on with no clue about Tesla to a show like this.
Thanks Terry. Beautiful work
I hate to admit it, but I prefer these teardown videos to Munro’s.
The Munro teardowns are good if “Munro” himself is nowhere near the action. My rather childish protest at his presence is a mandatory thumbs down. But yeah, these are great, I love them.
Exactly what I was thinking when Sandy is around he makes assumption and comments about the parts and design that he doesn’t even know why the engineers did what they did. Can’t wait for them to look at the battery pack and see what they have to say about the extra room in the battery pack.
Sandy is insufferable I unsubbed him a while back.
I prefer tear downs with facts. So I prefer Munro's tear downs.
It’s ok…Everyone has their preferences! 😊
Outstanding video, actually led me to have a better understanding of the "process." Cannot wait to see the next one. Loved how you have the parts displayed for us to view.
Cross-car beams: So a PHEV can’t do all the light-changes possible in a BEV, and have to stay heavier to take care of the 2nd powertrain’s effects.
Completely agree. Facts are laid bare on those tables. PHEVs are the biggest scam of this generation. Shame on Ford and GM for subjecting innocent Americans to this deceit.
Hybrids combine a lot of drawbacks with both types of power train.
Cross-car beams: The Mg one is lighter than all of the others and has the same features as the plastic hybrid which is heavier. For Earth Day 2024, let’s recycle these materials and stop using petro-plastics.
@@user-rp7rf1si8j Plastics in cars are in use for over 10 years.
Single use plastics are the problem.
Ignorance is the problem not environmentalism
The Tesla plastic over mold is single use due to the filler. 😢
These presentations are amazing John! Thank you for bringing this type of content to us!
Must be weird getting interviewed on your findings by a guy whos just ready to get out for his fishing trip, what a great vest, lol.
I’m the same way. It’s not only for heat retention, it’s the pockets, easy access to keys, phone, wallet etc.
Excellent video. Terry does an amazing job explaining things and as an automotive enthusiast I love this kind of stuff.
John always getting back from or on his way to a fishing trip!
NAILED MY EXACT THOUGHT/COMMENT!
Thanks Terry for sharing your discoveries.
I must be getting old, I like Johns vest.
Many great moments searching for phone, wallet, and keys.
So you're a vested interest ;)
This is a better video than the last one. Great job guys.
And every car journalist and “expert” was saying that Ford and GM can catch up to Tesla in no time.. 😂😂😂
Maybe if they fire everybody who says "We've always done it this way".
They do catch up!The Ford Lightning is the way better deal then the Cybertruck!If legacy cant catch up,how come Tesla only sells around 2 million cars this year?
Only?
It will happen when they get rid of all the "make work" projects that were made to satisfy the union...
😅 😊@@brunoheggli2888
Excellent presentation sir! The parts were well layed out and easily identified on the tables. I loved the evolution story on the battery table. Fascinating stuff!!!
Outstanding teardown discussion. I loved the comparisons, First Principles must rule!
I especially loved the Battery discussion.
Cheers, Eric
The expertise is huge. Thank you for this awesome video.
Thanks! Excellent John and Terry. Especially the teams at Autoline and Caresoft Global.
Glad you enjoyed it. Thanks for the support.
Love these, John and Terry; terrific! Keep it going... Viewing from Vancouver Canada
What a wonderful display and technical walkthrough and comparison. It takes a lot experience and wisdom to speak as simply as these two did about such complex engineering. Great stuff.
I'd add Full Self Driving to the benefits of the steer by wire. The extra bits are to completely isolate the steering function from the person in the seat, eventually.
All Teslas have FSD capability, steer by wire isn’t required for it to function.
@fredbloggs5902 I think they mean that the steering wheel will be able to be removed.
Speed-dependant variable ratio on front, speed-dependant direction on rear.
Feedback - that was one complaint hypothesised against steer-by-wire.
For a larger vehicle, you’d wonder why it took a century to dream it up.
Curiously, it’s the reason for going "48-volt". Which explains the century part.
@@iandavies4853 I just wonder how reliable all of these steer by wire components will be in ten years of winters, rough roads, etc. How safe is that old beat up Tesla speeding toward you at 160 mph relative speed?
Wow! Really fantastic video. So informative.
Wow great video. I love the comparisons
Amazing presentation, thank you.
32:32 What kind of shirt is Terry wearing? Oh a "Plade" shirt lol
I "plade" a different section of the video (32:59) and heard the same thing.
fwiw, his shirt is gingham :)
Thanks! - Clear presentation, true engineering art, learned a lot, confirmed my own concepts.
A company run by engineers advances the tech; one run by MBAs buys back its own stock.
Thanks for the deep insight and explanation ❤
I love to an amazing product. You're doing excellent work with this series, I really love it.
Very informative. Thank you.
Love this video!
Love matching these vids, what an expert on automotive engineering, makes the whole presentation so easy to understand for a non- automotive guy like myself.
Great job 😅 Super well done and interesting 😅. Love your content 😅
Very very good presentation. I’m slowly starting to love your work, maybe more that that of a quite famous, and quite entertaining, competitor.
Thanks learned a lot today.
Awesome video snd explanations! 👏👏👏👏😍😍😍😍
HEY keep it up! i love it, thrums up. this plus menro WOW
Than was great stuff, thank you.
Love this show. So informative humble people. Wow! Tesla is so far ahead of legacy automakers.
Tesla ahead of 'legacy' automakers?? Based on what? Ahead by almost going bankrupt and only saved by CCP financing and building them a massive factory, setting up a whole Chinese supplier network for them, forcing them to switch to Chinese batteries, and then flooding the Japanese and European markets with these Chinese cars?
What a complete 180° turn from Thursday's (yesterday's) show. Here we look at the future and how it's becoming part of the present. yesterday's show was about the past Digging its heels in saying nothing to look at here move along in the status quo. I'm sensing that John is slowly trying to convert all the Detroit motorheads to the EV movement. He can't push too hard or he'll lose a very large audience.
Exactly. Watching that show I was thinking, they just don’t know what they are talking about. Only echoing main stream media distorted by legacy auto talking points. Demand for EVs slowing? No. Look at the global figures. Demand for legacy EVs slowing, yes. Plus, they don’t want to make them, because they are losing a lot per vehicle. So they will build hybrids for a few years then go bust. They will be saved by the govt or bought by the Chinese
@@89bazolythe fact that you say that, really tells me you have no idea what you're talking about. Unless of course you just admire China so much that your loyalty to America just jumped out the window...🤦
@@jeffcarroll3831No, it is just logic. Legacy cannot change fast enough and will just try to mitigate their demise. The Chinese can be admired or not, it has nothing to do with loyalty. Loyalty to a failing system is your problem.
@@BjorckBengt that logic you speak of....is faulty
@@jeffcarroll3831how will legacy auto compete with the Chinese? Protectionism is the only way. It still amounts to government aid. No emotion is required in this assessment.
Legacy auto in the US is about making trucks and the profit margins on those will come down, already happening.
Good stuff.
Clear and sensible presentation, even for a non- engineer. Kudos!
Way cool! There are always pros and cons. Aluminum wiring has major reliability issues compared to cooper. Not always a good idea to have tanks (or battery cases) subject to external shocks. Glad that Tesla is paving the way.
This is a great show.
The engineering behind the Cybertruck front/rear steer by wire is mind boggling. The average buyer simply won’t appreciate the design, engineering, validation and precision parts manufacturing that went into the CT.
It isnt mindblowing at all!Its just ok!
Infiniti Q5 has had steer by wire since 2014.
The reason I pulled the trigger on a Model Y in early 2020 was because I watched Munro tear it down. That said, I did plan on buying an EV and had just installed more solar + a Nema 14-50 receptacle in my garage. But, my original plan was a used Model 3 at the time.
@@brunoheggli2888 SWEETIE, YOU'RE TROLLING TESLA?
@@user-vx7vi3vq1c IT'S GONE, IT WAS A SHORT LIVED TRIAL.
Very nice!!👍
What a wonderful display. You can tell much thought went into this presentation. THANK YOU
Thank you.
Yes, these are better as we get comparison shown to us.
Also, Munro is now inserting adverts for other businesses into its videos.
This Caresoft/Autoline presentation of what Caresoft can do is far superior.
Even though Caresoft is paying to be on Autoline, what we learn about products is not diminished.
Its a pity that Chinese companies are queuing up for learnings from Caresoft and other businesses, but US and European not so much.
Great info about vibration at low speeds in combustion engine vehicles.
The student has become the teacher grass-hoppa.
Wrong!
Amazing
Well done.
In both EV and ICE, it seems that power density matters more than energy density. You can always recharge the battery, be it from an alternator or the high-voltage pack of an EV. If you can increase power density for the same energy density, you could make the low-voltage battery smaller. But what battery technologies could help with that?
John this is absolutely fascinating. The applications for this steer by wire system are so broad reaching into the future.
fascinating!
Awesome! I also like the pre ceramic 2-tone Rolex Submariner Terry is wearing. 👍
John always looks like he’s coming from or going on a fishing trip.
Terry is inspirational and thorough in his pursuit of excellence. A bit like Tesla Engineers!
Far more informative than the Munro tear-down.
Stunning how superior the Tesla engineering is over legacy manufacturers. Unsurprisingly when it comes to batteries and the EV drive train, but it blows me away that they reinvent the fundamentals like steering and the front dash cross car beam. Achieving lightness, cost efficiency and superior functionality all at once......
Tesla engineering isnt better then Legacy!
None so blind as those that will not see such as @@brunoheggli2888
@@brunoheggli2888 Lol!
What makes you think they are better at steering? Steer-by-wire? Rear wheel steering? All have been done before.
And for the front dash cross bar - the plastic clip on is a thing that I do hate on any modern car. Plastic tends to weaken over time, and plastic clips tend to crack. Unlike a bolt or screw. And yeah, sure, in a manufacturing perspective (and cost), it might be great, but it does suck for anyone who wants or likes to fix or upgrade their own car.
@@midakassi "REAL" steer by wire is a First with the Cybertruck (no mechanical linkage) Some earlier attempts all had mechnical linkage as" backup" which is a glorified power assist system...... You are correct that rearsteer is no innovation as many cars have had it before. Not aware its been used in the truck segment before, but thats just a minor thing in anycase. So what are the innovations that blow me away? The gigacastings that reduce complexity, increase quality and reduce weight. The dual purpose use like the model S suspension airtank and brace. The dashcross bar might not be a good solution for adding other mods, but brings lightness and ease of assembly that drives down cost with-out sacrificing functionality. The 48V architecture and ethernet ring reduces weight, cost and improves speed og communications and performance for the energy hungry low voltage devices such as the steering rack motors. Oh, the Octavalve heatpump system, while heatpumps are not needed In ICE cars that turns most energy into heat anyway. ITs the kind of innovation in simplification , integration with high performance. Kind of like the Semiconductor world.. Maybe some of that Silicon valley DNA is why Tesla is so disuptive even in the areas where legacy has nearly a 100 year headstart ....
It's amazing how advanced Tesla is in their engineering. You can see EV's are the future despite some current misgivings. ICE cars 70%+ inefficient, EV's 70%+ efficient. Soon to be better with new battery technology. I can't wait !
Yeah, you better get used to waiting....
Very nice walk-through, thank you. In fact... have a coffee! :)
We're glad you liked the video. And thanks for brew. ☕
It's great to have more than one tear down series. More inputs. :)
I also find that Tesla is forcing all other auto manufacturers to change just by introducing new technologies in every new model or "refresh". (As well as all the over the air updates).
Excellent storytelling as well as providing context to addressable problems/benefits that are relatable to a broad audience.
Tesla told us the battery pack would be pressurized during Wade mode, a feature that has to be invoked by the driver on the touch screen, but will it come on automatically too?
Well presented, high on facts and relevant context. And an interesting way of demonstrating how legacy procedures directly hamper creating the most efficient EV designs.
Redundancy in aerospace, as fas as I know, works a little differently. You wouldn't just duplicate (or triple or quadruple) one actuation mechanism, but also make sure to have one or two different actuators. In the case of Tesla's steer-by-wire, the second eletric motor would at least have to come from a widely differing production batch, or even another manufacturer.
6:15 this is the most crucial part to the whole steering system, without this on slippery surfaces you would just spin out so easily
so interesting
Wow, the gas car is like before the invention of electricity.
This is way better than Monroe who used to be this good but now has lost his way dramatically. Thank you for this wonderful presentation of an extraordinary development not turning in the Cow world in the Production world itself.
I was really curious about the Cybertruck’s air tank. Thanks for showing it.
We have a structural battery pack and the S has a structural air tank. How can the Cybertruck have its air tank integrated into the structure or frame?
There might be many frame parts which can be designed to hold pressurized air. It doesn’t need to be the crossbar. Since air can take any shape, that really opens up the possibilities what part of the frame can double as air tank. This would especially apply for the semi.
You showed a tube that holds the dash assembly. That’s visually a first place to consider for an air tank. We don’t want an air tank to blow up in someone’s face, so there could be weak points built into the front of this tank, so a blast from a tank rupture would more likely blow the air away from the cabin.
What if the suspension cylinders at the wheels were slightly larger, so you had 4 small tanks instead of one large tank?
This video should be shown to every secondary student 😊
Can you please upload these full videos on X?
Crossbar beams comparison:
STEAM-PUNK vs SPACE-AGE
Its amaxing that when people buy a cybetruck the first thing people want to do is pull it apart to see how it works.like an alien spacecraft.
It’s literally his job and the car industry have been doing it with each other’s products for over a century.
CT has a high water mode that pressurize the battery it takes about 5 mins to engage.
Tesla is on another level.
No it isnt!
@@brunoheggli2888 DID YA EVEN WATCH THE VIDEO BRUNO?
@@brunoheggli2888 Please provide some evidence of your assertion. Facts don't care about your feelings.
@@MICHGO1Did you? Do you understand what's missing from the video?
Do you understand that lots of scammers make youtube videos to make money off of the clicks of absolutely clueless people? Now go watch some crypto videos, and the "one trick to make a million dollars"...
It wouldn't look that much more complex than gms system, if you didn't completely disassemble every part and spread it out across the table. It honestly seems intentional. I'm looking at all the parts for the Tesla. And trying to imagine it assembled. Also, you're not showing the power steering pump, Which would no doubt make the gm system look more complex
the steer by wire system you can tell require software engineering. The electric car is more like a computer. We all know how computer technology keeps coming down in price while advancing in computing power and efficiency and everything else. Batteries also will benefit from chemistry advancements while costs will keep coming down. Unfortunately for the gas powered combustion engine car it's had its day..., it can't compete with computer on wheels. Maybe a 9 year old by the time they turn 16 they might not want a gas car... that's just a few years away.
Awesome to see this. And I'm thinking that this version of cybertruck is the crudest and least optimal design it will ever have. From here it will only get better and all the stuff learned will go back into their other cars. I hope Caresoft finds this UA-cam association with you profitable.
Thanks. And we agree it will be interesting to see how Tesla applies what it has learned on the Cybertruck to its other models.
