There's at least 5 Tesla VP's standing around here.
Lars Moravy (vehicle engineering)
Drew Baglino (powertrain & energy)
Pete Bannon (electronic systems)
David Lau (software)
Franz Von Holzhausen (design)
It's almost impossible to get a slot on these folks' calendars, so it shows how much Tesla values Munro.
Great insight! 👏👏
Dick ride much?😅
the TESLA A-team.
It's not just that they value Munro, they value the communication (advertising) Munro provides.
Tesla does advertise, they just don't pay for that advertising in money. They pay for it in employee hours.
And don't forget the guards in the background shooing away the Great Unwashed.
The transparency of the Tesla team when speaking to Sandy, or the wider Munro team, is extraordinary. Tesla are building the future of car manufacturing. Thank you, such a fascinating interview and review of the Cybertruck.
At 07:08, whoever noticed this point in the video might find it important under the repair rules, as repairing may not be possible due to the nature of it being an aluminum stamping material part.
When Sandy mentioned repairs, it seemed like the Tesla engineer felt uncomfortable. Please re-watch it again. Tell me, am I completely wrong here, or is there more to the story? 😳
@@AwesomeBlackDude I think we know that these really aren't repairable, but they won't say it. lol
They're building a new manufacturing culture in US.
Talking shit listen to John c the Australian bloke
If you hit the truck hard enough to damage the casting there would be enough energy created to damage a similar built up welded assembly beyond repair. In both cases the truck would be totaled. I did see that Tesla is selling the castings for the model Y now so that they can be replaced and they also had replacement elements of the castings like the crush areas. Pretty interesting.
I think the point of the castings are to bring the cost of the cars down enough that they are affordable, which is a whole new paradigm in the auto market. Much like the model T. It’s initial cost was $700 and when they quit manufacturing them 11 million units later, it was like $275. I think that kind of reduction in the cost of automobile is Tesla’s end goal.
From this one video, there's probably 20 auto OEM management teams around the world conducting engineering re-evaluations of their entire chassis design and assembly process. These Munro clips are amazing corporate transparency from Telsa, underlining unprecedented commitment to making the world a better place, in addition to be a great marketing exercise.
No they're not, Jesus Christ, people like you will literally believe anything won't you.
And so far ahead, they don’t worry about copying by others too soon. Same with Elon sending around 48 volt info (unless that was just to troll OEM’s)
@@johnryan6003 Oh, there's no way other car manufacturers have considered different voltages, that's way too complicated for them.... lmao. You muskrats are genuinely hilarious, how are you even smart enough to use the internet? Genuinely, I can't understand how somebody can be so mentally deficient.
@@johnryan6003the 48V document is a good and selfish move from Tesla. It is to help the industry/supply chain to pivot faster to 48V standard.
More OEM using 48V leads to more suppliers offering more 48V components which make building a 48V vehicle easier.
Its cool how genuinely excited lars is to show all of this stuff off. Like a kid with his science projects.
As an engineer I really admire this guy. Elon is lucky to have Lars.
Agree, and would love Lars to take over many of the quarterly and investor presentations. He's articulate, obviously a gifted engineer and his love of the science shines through. Over the last year, Elon's name has unfortunately become too synonymous with political divisiveness. I'd love if he could somehow refocus his attention back to what got him here...pushing cutting edge tech! I'm all for freedom of speech, but its seems lately Elon is willing to potentially risk the company to prove a point. I just don't want to see Elon blow up his own mission because he thinks free speech will be lost forever. Social movements are often slow moving and tough to budge, but there's finally signs the hyper woke stuff is starting to self-correct. Disney, for example, is realizing massive financial losses as a direct result of their woke decisions, and the presidents of many Ivy League schools have pushed the woke agenda to the point they're actually loosing their jobs. I really believe we will continue to toward a more sensible, moderate middle.
@@tnelly6588 Somebody different on the quarterly call would be good. Talk of digging our own grave and PTSD didn't help anything. 3rd quarter call was like a funeral.
Disney - It will be interesting to watch the court case in Florida. It's very important to Disney.
Excellent to hear the engineer himself talk, More please!
Yes more please. I really like the river flow. These people are not doctrinaire. They learn by doing. That was the motto of Mike University which was a big-time Engineering University.
“Learn by Doing”
Absolutely mesmerized by this deep dive into Tesla's Cybertruck. Sandy Munro's insights, coupled with Tesla's innovative approach, is a testament to how the automotive industry is evolving. It's not just about the truck's bold design or its 'exoskeleton' but the whole philosophy behind Tesla's manufacturing and design approach that's paving the way for future vehicles. Excited to see how Tesla continues to revolutionize the industry! Who else thinks Tesla is setting new benchmarks for others to follow? 🚀🚗 #FutureOfAutomotive #CybertruckRevolution
What other car manufacturer would be this transparent with Sandy Munro?
Hi @DPCcars. Can you guys reupload that crash test comparison video from the other day to represent a like for like test?
You were basically comparing a cybertruck hitting a whole ass wall to an f-150 hitting a bench.
Well, everyone is already following them down the gigacasting road. Likely, their shift to organic shapes in the castings will also be followed. Not sure about the giant stampings, that seems higher risk than the gigacasting route. And no-one will follow them down the stainless hole, its all hype and costs more than they claimed it would.
Great information! Thanks Sandy, Munro team and Tesla!
Please stop saying exoskeleton! Its a stainless steel skin. Lets just be real ok 🙏
Those castings are insane.
So there's a part 2, still sponsored by Ford? 😅
Aged like milk after the frames began snapping in half
Amazing design on the substructure. Casting with metallurgy shot flow in mind. The CyberTruck is part spacecraft. Part UFO. All future. And it’s here.
I hear a lot told about engineering, development, rigid structure and how tough this car is built. But noone talks about safety, engeneered deformation zones, impact energy absorbing.... I WANT TO HEAR THIS, but not about,how bulletproof car is....
Cast aluminum frame/ steel paneled body: snaps when towing
Steel frame/ aluminum body: greating durability, no panel rusting
The way they are talking about this ugly truck you would have thought they reinvented the wheel .
This thing would have been worth while as a work truck at $39,000 but no way is it worth over a 100 grand .
Who did they make this for ? a truck doesn’t need to go 0 to 60 in 3 seconds neither does a luxury car priorities all wrong on this .
The interior looks extremely cheap and plain it doesn’t look like a place you would want to spend much time in .
The exterior is very crude no style to it and having a stainless steel body will be a nightmare to clean imagine the finger prints all over it .
The design came out 4 years ago now that you can buy it all ready looks old yesterdays news not fresh anymore
"Full Self Drive" all over again. What exoskeleton? Looks like a standard unibody.
For those who haven't realized this yet... "exoskeleton" just means "unibody"... like nearly every other car.
"Unibody" means unitized structure and body, in contrast to separately constructed frame and body.
The external stainless steel panels are part of the structure (because it is a unibody), but they are not the entire structure (as a true exoskeleton would be). Late in the video, the Tesla rep explains how the rear aluminum casting is the critical structural element of the rear of the vehicle... not the surrounding panels.
It is becoming common to include more than one material (steel, aluminum...) and even more than one component production method (stamping, extrusion, casting) in the components which are joined to form the unibody. In the Cybertruck, there are stamped boron steel, cast aluminum, stamped stainless steel, and formed (bent) stainless steel. There are also aluminum extrusions and composite (fibre-reinforced polymer) parts attached to the unibody, but not an integral part of it.
The machines that make the machines is the most fascinating thing to me. The intellectual process & how decisions are validated too. Really the best engineers working at Tesla right now.
TESLA took stock Brake machines , and moded then to TESLA specs to fit their needs.
You're joking ryt?
@@TheMrgoodmanners - NOPE , true story.
Standing in front of the exposed internal casting structure with a camera rolling and still calling it an exoskeleton 😄
I wonder if that marketing spiel is worth the damage to credibility.
My pick for next CEO is Lars or Drew
Why?
Why are you even talking about this? Elon will probably stay for the next 20-30 years.
@@themonsterunderyourbed9408he will go to Mars, to make Mars great again.
It's gonna be Tom Zhu.

After describing technical details and mold flow simulations, Tesla's engineer looks bemused at 9:00 when Sandy describes bashing the m3 with a hammer.
I'm sure he's see the video
@@rogerstarkey5390 I wouldn't assume a busy engineer has time for that sort of thing.
Completely bonkers how Tesla operates. To them, once the project is out. They know their is no motivation on holding back information. While they don’t spew out models. I really think this is warfare by innovation.
Not Warfare.
If that were the case they wouldn't have told everyone what "The plan" was (is)..... Several times.
There's certainly trolling, but that's just trying to encourage the laggards.
Just shows how pitiful we've become when you call innovation warfare.
Struggling to find a reference as to how the steel panels are attached to the frame. A video 9f the robot handling them on launch day is inconclusive. This is pertinent to discussions regarding cost of accident repairs.
Would have been nice to have a discussion about those the stainless panels are hung. Are the edges folded over and drilled out for hanging? Are there stamped hangers beyond the door ring or is everything bolted to the castings? Clearly there has to be several cross car brackets for mounting the IP and the frunk, lights etc. Im asking because the "story" on cybertruck has been a reduction in stamping, but what we are actually seeing is the largest stamped door ring ever. So fewer individual stampings, but bigger ones to reduce the amount of overlapping and welding required, and reducing overall time in assembly.
Its also interesting to note the contrast between the angular exterior and the curvaceous organic shapes on the stampings and castings. Reminds me of old school cast iron "asthetic era" machine tools with swooping curves.
Probably in the production. Video coming soon
The edges don't seem to be folded over, and I guess that's why the vehicle does not meet pedestrian protection standards to be homologated in Europe?
@@deltajohnny well, the sharp corners and weight in general are enough to do that. Apparently europeans care about not decapitating children or something.
@@patreekotime4578 I'm sure that in the future, the US will also adopt these standards 😉
@@deltajohnny right after we ban fossil fuels and soft drinks.
This is the kind of "peaking behind the curtain" type of video that this channel should do more of, with the actual engineers on the project. MORE PLEASE
It is funny how it is flat outside but organic inside.
It is flat on the exterior because they could not stamp the exterior stainless steel panels without marring the finish, so they were limited to folding them. Interior forms are curved because that is what they need to be for strength and manufacturability in the processes used in the interior (casting and stamping).
it's impressive how freely Tesla is willing to talk about their engineering and software feats and share what is basically their proprietary trade secrets. It really shows how unconcerned they r with competition as they r so far ahead
Note, that the revolutionary building process and the immense reduction in the number of parts has made it possible for them to sell the vehicle for ONLY 50% more than what they said at the unveiling event and removed almost any form of crumple zone (which has been a safety standard for any car since the 50s).
@@Assywalker It still has a crumple zone, it just doesn’t look like a typical one because of the exoskeleton and no gigantic engine block.
@@Assywalker Have you watched the crash tests for the Cybertruck? Why say stuff that's %100 wrong when you actually have no idea?
@@chamber32doors
I did and it is really bad.
That's really all that needs to be said about it. There is a reason we stopped building cars this stiff decades ago.
Which is quite suprising, given how well other Tesla Models did in these tests.
@@Assywalker You are mistaken, sir. ruclips.net/video/9ll2_BDZpI4/видео.html
Tapered self tapping threaded inserts is brilliant on a whole new level...zero machining on that casting...the best process is no process.
"...much like our castings we have to make the press." After a long pause Sandy asked who did you buy?
At least Sandy wasn't takkng the Tesla B.S. train sitting down!
Everyone is happy to see the casting, but I see the problem that even with a small accident, the owner will change the cast part entirely. I think it will cost at least 10 grand. A dubious decision.
You are obviously unaware that there are Crush cans to sacrifice in low speed crashes and segments that are weldable in bigger accidents, they have it covered, and if it’s worse than that the casting is good to recycle ….
What worries me is that they integrated the cruch can into the casting. This means that in most crashes, the front casting will need replacement. Insurance companies won't like that.
The crash can is integrated into bumper, as mentioned on the other video. The additional crash absorption in the casting is for the severest impacts. At that point you wouldn't want the structure repaired and back on the road anyway.
Any vehicle crash in which the crash rails are destroyed these days is almost always a complete write off. They're designed to lessen the impact felt by the driver and other occupants not save the damn car from being totaled in an accident. I seriously don't understand the ridiculous argument that crash rails make the car easier to repair, that's not the damn point of them. Low impact accidents, which almost any vehicle will survive largely intact won't lead to Tesla being totaled. Will you need to replace the crash rails? Yeah probably cause they'll get bent or broken in some way, but that's not their intended purpose.
1:30 The A pillar looks like it’s 8 or 10 inches front to back. I don’t have any problem with the size but it screens the driver’s view. What stops the pillar from being at 45 degrees instead of long front to back? You get the same strength but the driver sees the smaller dimension so his view isn’t blocked as much.
Exoskeleton my ass😂
Future just started -thanks for taking us with you
Kudo to Ford for Swallowing their Pride and for the Tesla Teams in their Humility! Well Done Elon and Teams!!
It still sucks. You cannot modify or do your own stuff on it. Besides the 0 to 60 crap. what can it do beyond. the le mans and It has no heartbeat. It ain't alive.
This is the coolest piece of engineering ever produced 🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌
As a non engineer this is like watching the future in real time
Unlike steel, aluminium don't have a fatigue limit (ie: it will continually deteriorate from _any_ small stress, while materials with a limit wont unless you pass a certain threshold), which means that a) they must incorporate higher stress tolerances to have a meaningful lifetime and b) will weaken over time.
How do they incorporate this into the design, how large tolerances do they have, and what is the design life (and just to rehash, materials with a fatigue limit doesn't have a life limit based on stress)?
These videos are awesome but I feel like Sandy has basically become the Tesla marketing team.
Tesla is where the innovation is happening. When did Sandy get access to the engineers like this at other companies?
First glance the body construction looks like Saturn aka GM S series design, substitute polymer panels for stainless. Those castings look extremely unrepairable but likely are faster and cheaper to produce than stamped steel.
Is it repairable or any crash totals it?
Imagine the body shop that has to replace that casting because of an accident.
The Exoskeleton = Unibody, stop the cap.
Everyone is exited, until we start to get statistics about injuries in this steel coffin
....and how is it possible to fix the cast after a crash ?
Bugger all repairability.
Instant write-off
It seems like body damage would be very hard and expensive to repair
Looks organic , alien dreanaught indeed. Amazing ❤
It’s awesome to see the amazement from Sandy !! This is such a beautiful machine inside
When a person says 'these' it means closest to oneself. No need to say 'these here'. Both men improperly used terminology 'these here'..
which is being redundant.
These ones - yankee talk. Good luck being the word police.
Fascinating, a company revealing cutting edge engineering and manufacturing real time 🤔
Small crash means car is absolutely totaled!?
So in a side panel accident that whole piece has to be replaced??
Damn.
That’s major repairs. Cannot just replace a panel.
The door frame (including both front and rear door openings) is normally one piece on modern vehicles.
But its not an exoskeleton is it? Its a unibody like any modern car now
Absolutely yes. Realistically, it was never going to be an exoskeleton, because that would make no sense for a car or truck.
@@brianb-p6586 yes i know, my point is nobody in their right mind should believe anything mr. Liar liar says
Wow this is next level 🎉
Whoa! That was spectacularly informative. Keep that guy happy!
The front end is just 1 piece cast? So if the front fender is hit hard enough to break that, you'd have to replace the entire thing??
The outer fender is stainless steel, there's a non-stainless inner fender under that and the wheel housing is part of the aluminum casting. If the corner is hit hard enough to damage the casting... yes, that's likely a total loss of the vehicle.
I honestly believe that all the other car manufacturers are scratching their had for sure
Very impressive, but I wonder how expensive that would be to repair? Ouch!
So basically it has bits which will go rusty on the inside, and a non-replaceable battery.
Why do you think it has a non-replaceable battery?
Is it just a coincidence that this video keeps getting interrupted by Ford F150 Lightning commercials?
No Ford sponsored the video
It was fantastic to hear Lars discuss some of the details of design and the casting. Really interesting. Thanks to you and Tesla.
Im so confused. Can somebody help me understand? I thought it was announced months ago the first runs of the CT would not be exoskeleton. What changed?
Nothing changed. This is not an exoskeleton, and it was never going to be.
@@brianb-p6586 it was never going to be? Bro. Just watch the first Cybertruk event. Ya nut.
So it doesn't have an exoskeleton
The Cybertruck's front and rear end are manufactured that way and made from 6000 series aluminum. According to official recommendations, frame straightening isn't allowed. "Pulling or pushing the body structure can damage the integrity of the component," says Tesla in its structural repair guidelines. bottom line: aluminum has no ductile strength.
Guaranteed Ford and Toyota re watching this on repeat!!!
Hello. Can you tell me how the parts from the gigacasting are attached to the stamped body parts? Is welding applied? If so, which method?
And how the galvanic pair is provided.
Thank you.
This is one of the most disappointing vehicle launches of recent memory. Idc what anyone says about the stainless steel body panels. They’re terrible for a vehicle. They’re already rusting when exposed to rain, stainless is a fingerprint magnet, scratches easily, can’t be patched and repainted like regular painted car body panels. The other problems are the horrendous real world efficiency. People are getting 600-700wh/mi at 75MPH. That works out to an abysmal ~185-200 miles of range. Charging at a V3 Supercharger takes 45 minutes. The battery capacity is way too small for such a thirsty beast. Steer by wire doesn’t improve the driving experience. The door opener buttons are too tall for children to reach to get in the vehicle. Rear headroom is poor. So many things they did needlessly to appease Elon.
Lars is an engineers engineer!
Give the customer the option of having the extended range instead of the sub-trunk. The "range extender" in the bed is STUPID. Put more range in the sub-trunk area!
Munro: "There's a couple of things that people don't quite understand. And one of them is, how do these things crash, and blah blah blah." Yeah, potential buyers are so tedious and boring when they wonder whether they'll end up a paraplegic if one of these Cybertrucks crashes.
Or maybe he's just got a bad case of jetlag. 7:06
Ductile is key. High quality aluminum with just the right grain size.
Insurance companies love giga castings ❤
Sarcasm? I see a lot of starry eyed comments about how cool this is, but this just seems stupid to me. I understand how awesome this is for the manufacturer, but as a consumer this is the worst way to build a vehicle. You don't even get a right side / left side casting, just one big casting that will crack/shatter in an accident. If they made these available inexpensively to independant repair shops then fine, but I would guess thats not the case. I guess if you can afford to buy one of these things money is not a huge concern.
OMG this is freeking amazing!
Just curious, but has anyone else been getting hit hard on these videos with Ford F150 lightning commercials at the beginning? So far everyone of these videos has an F150 lightning commercial attached to it lol
More info on repairability and replacement parts would be nice 😊
Irreparable, useless over weight nonsense
This is what most people don't understand about Elon Musk's brilliance. Locating the casting team beside the engineers personifies first principles thinking and it's why Tesla's system is an order of magnitude more efficient than the competition.
Elon's brilliance on display at events:
Full Self-Drive, NEXT YEAR! (10 year anniversary of that perennial statement incoming)
We can convoy trucks now and it's cheaper than rail!
Starship to launch for Mars in 2022!
Hyperloop isn't that hard, it's like an air hockey table!
New Roadster in 2020!
Winge Winge Winge@@jessederks8458
Your take on Elon Musk is narrow and your criticism is odd. So Elon Musk is a slacker and exaggerates how long it takes to do the impossible? What a dick.
Believing there's nothing you can learn from Elon Musk is extremely misguided and breathtakingly arrogant.
Most controversial truck ever maaade ❤
Meanwhile, in China, SEVEN EV's CATCH FIRE EVERY DAY.
How much of the deflation has Tesla provided when the #1 car has dropped 25% Joe?
What type(s) of NDE are done on the castings for quality control?
That’s why this is a vanity vehicle not a truck a truck needs to be able to be outfitted any way the customer requires after the clout chasers buy theirs why would anyone buy a truck that can’t accept a standard camper or tow a 5 th wheel or put a tidy tank on or even a service body it’s a toy not a tool. That’s the most disappointing thing about this unit it missed the mark so far it’s confusing.
the version on the crash test the subframe was zn coated. But this one es black powder coated. Wonder the Zn coating was omitted.
A look at the HVAC and battery systems, and maybe a teardown will not be necessary. I see what Tesla is doing here, They are trying to save a CB!
Thing is like a space ship.
Transparency or not, if something cannot be repaired after being in a collision, well, form your own conclusions.
i wouldnt talk to this guy whos selling manufacturing info to competitors.
Some insider terms that I'm not familiar with like "shotgun, nodes & I think "high ketones"
They powder coated the door opening steel? And I thought a paint booth was messy. Powder gets everywhere!
OK but they have to be something for corrosion and looks. Maybe you have a better idea and you can suggest it to them. I’m not being sarcastic I’m just saying that when you have a criticism I like to see your idea that makes it better
Could you guys borrow an XRF scanner and once and for all reveal what the stainless steel alloy of the skin is made out of?
Go Sandy. Your info should be reqd study for all students . JIM
That's really interesting. Talking of towing, is Tesla going to integrate a Load Cell into the towbar so they can accurately calculate predicted range based on the actual resistance of the load that's being towed?
Certainly would be easy to do. Just put a couple strain gauge rosettes on the hitch. The rest is an op amp, A2D converter, and some software.
Unnecessary. They have to figure out the loads inside the cabin and on the bed though indirect calculation anyways.
no need. they can compare power draw vs acceleration to calculate weight
Hitch weight is only a small factor when towing. Is it a car carrier, travel trailer, enclosed cargo? Too many variables.
No need. Range can be calculated by energy used vs speed. Simple.
Now go back and reevaluate your fanboyism 😂
Good info. Keep on keeping on.
Can anyone explain what is shot gun meaning as regards to welding in:
1:54
😍
Why are you guys repeating what you already showed in the previous video?
Cool engineering, but it looks like it would cost an arm & a leg to repair if one of those casting got damaged.
Nice video! I’m sure OEM is using their microscope!
Lot of people out there disappointed that it's not all stainless steel; it's just got a normal steel unibody.
Using aluminium castings to take suspension loads, bed loads, towing loads, isn't good for longevity.
It's an alloy. Tesla has actual metallurgy experts.
@@snookmeister55 Do you know what an alloy is? there are aluminium alloys and steel alloys of varying metallurgy, of which it appears you know nothing about..
And this is one of the reasons why ford lightening production is getting slashed in half
