I love how you explained the structural things by comparing it to what is 'dead weight', like on a body on frame design. Also made me see the significance of making 1 part do more than just 1 thing.
The reason pickups trucks are body on frame is user taxation reductions over car tax. People now buy big pickups as their main vehicle for home & work, but in the UK, a higher value pickup can be £120/month tax (20%) vs car tax for the same value rated car at £600/month. P/ups are classed as agricultural/industrial vehicles, not cars with an open boot/trunk, due to to the separate chassis. I suspect a similar scenario exists in other countries. This also explains the massive popularity of truck sales in the US where there are more self-employed tradesman/businesses than in the UK. I suspect Tesla have looked into this before not having separate Body/chassis in the CyberTruck.
I do my best not to rehash what people have already seen too-many times, so glad you think I succeeded. TBH with so many words discussed about Cybertruck, finding which rabbit-holes are still unexplored and worth going through for the third video in this series is becoming a bit of a problem (but a fun one to solve). For the 1st vid in the series: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Y41rHaTGgWY.html and thanks for the feedback
I did know about the drag coefficient and the truss design, I missed so many things. I had thought the exoskeleton was just to lower weight, I mean it is but I didn’t know the why or the how! Thank you so much for this video 🙏
We have a small farming operation in the mountains of northern New Mexico. We can't wait for our his/hers cybertrucks. I am so sick of gas and diesel engines. I can't wait for fully electric farm tractors. Imagine how low the center of gravity will be. And if you ever looked at a modern tractor, the complexity is ridiculous. You just can't maintain them yourself. Electric tractors will be so much simpler and you can charge them using your own solar power. To hell with paying for diesel. Our first order was ~40k in line. Then my wife said, hey wait, I want one too. That one is a bit further back in line.
And yet I’ll bet she’ll get the first one, lol With EVs, you can get that much closer to being off the grid if you generate your own power. Hopefully they make the CT repairable and DIY friendly.
@@thedownwardmachine They would make them repairable IF teslaQ wouldn't use the access to sabotage the vehicles and pubkish widely more anti-ev FUD like they have over the past 10 years.
@@thedownwardmachine The amount of solar or other free electricity generating devices required makes it unviable, especially for a Cybertruck, at this point.
@@jackylsmith8138 I'll bet when they set the price for cybertruck they didn't anticipate 1.5 million pre-orders. That obviously changes your initial construction plans.
Cybertruck makes me consider a pickup truck for the first time. It really is revolutionary in a good way, using engineering to solve problems that most ignore or just don't deal wtih.
I never fully understood the logic behind the Cyber Truss design and now I understand how and why it adds rigidity to the CT no other vehicle can match. Everything about the CT is brilliant engineering that makes all others look so last century and antiquated. So glad I reserved my dual motor in November of 2019 when it was first unveiled. I don't mind waiting since it will be so worth it.
@YYpang Yeah and the Tesla semi is now in production which uses 4680 cells. A good sign for the cybertruck as the semi releasing is more important for Tesla and now that the semi has started production they can get the Cybertruck next.
@@Supraboyes yup. EV's have their place in very dense urban environments were space is issue, charging opportunities abound, range isn't a issue and pollution is viewed as a major issue like NYC. EV's aren't a viable solution for rural Texas...
This is the first exoskeleton explanation I've seen which explains deeply enough for me to understand why it's superior. I've struggled until now to understand why exoskeleton is so different than unibody, but now I see it's basically a question of how little dead weight there is. The multi-functionalism present throughout the design makes me confident no other all-electric truck stands a chance at matching Cybertruck's efficiency for similarly capability. Also, it never occurred to me that you could overcome the side trusses by lowering the suspension. Genius!
Bullshit!!! The exoskeleton is the stupidest option, body on frame is the way to go! Is tesla also going to make a ford f450 equivalent with the same dumbest design!? What about actually commercial vehicles!? Grow up!!! You litteraly made everything look good for tesla 🤡 🤡!!!!
The air suspensions is actually not needed lol….. that also extra weight added on the car and the cybertruck won’t even have the range to compete with the tiny Toyota hilux(almost 1000miles)
Good job. I like the techiness 🙃 of it. I've been in technology fields as a career and hobbies all my life, retired now. You pointed out things I missed and I thought I had it all figured out. Keep up the good work.
Good point on the buttresses. When people say they won't work because of their height and the interference with bed access from standing outside of the vehicle. Lowering the air suspension all the way is such a simple idea. The simplicity is elegance. The truck has air suspension for a variety of reasons, and lowering itself for easy bed access is just one of them. Nice. 👍
I have to admit I fell in love with the CyberTruck at first sight. It reminded me of some of the classic designs of the past. To say it's reminiscent of the Airstream Trailer, P51 Fighter or the Mercedes Gull Wing is for me not an over exaggeration. This vehicle is a revelation in its simplicity, it's performance and it's complete disregard for the status quo. You can just imagine Engineers at Tesla when they were told forget everything you know make the best truck possible 🤔🤔🤔Talk about a Boss Moment 😎😎😎
I am surprised how little crash safety is discussed. Rocket scientists get a lot of praise, but we tend to prioritize performance and control to avoid crashes, rather than focusing on crash worthiness. Skeptics argue that the Cybertruck will be inherently dangerous in a collision. The entire structure in front of the passenger cabin will need to crush and deform to absorb and deflect impact energy. The front fascia and hood will likely be made from much thinner stainless steel to maintain the durable finish, and separate from unyielding exoskeleton structure. It will be fascinating to see how Tesla connects the exoskeleton to the underlying gigacastings. Will it be Mechancial Fasteners? Welds? Chemical bonding/ adheisves? or maybe something new. Munro Live is a great resource for learning about these topics.
As a retired Structural Analyst (Mech Eng) I was hooked from the moment you said “first principles”. Excellent discussion and analysis. The only minor point I would add (and maybe I missed it) was from my own first thought on seeing the Cyber truck...”Truss with Kamm tail”! The Cyber truck design cleverly takes the “truck bed scoop” that kills gas mileage and turns it into an aerodynamic improvement over even trucks with bed covers. And of course “purity” was a good choice of words to describe the design. I like the inherent robustness of having an exoskeleton that distributes uniformly all stress (and ultimately even plastic deformation). For the life of me though this seems impossible to convey to “haters”. Perhaps your video will make headway, hope so!
I once saw a mileage analysis of a pickup truck depending on bed use. Open tailgate, closed tailgate and flat cover were tested. I only remember that open bed with tailgate closed got best mileage. The closed tailgate captured a low pressure wave in front of the tailgate and air flowed over it very easily. Completely counter-intuitive. Worst was covered bed. Blew my mind.
Only found your channel yesterday, but I’m subbed 👍. I’m in my late 50’s and also from an engineering background. My field electrical and electronic, I went EV in 2019 because to me the physics of an AC induction motor make perfect sense for any vehicle driven by wheels - storing enough electrical energy was the block on this, but Tesla thought outside the box - remember when everyone laughed at the idea of powering a car on laptop batteries? The Cybertruck is awesome, at the reveal, I was shocked; like so many, because it was just too radical on they eyes. Since then I have come to love it for the sheer bravery of its engineering principles. Legacy auto is run by accountants and marketers, Tesla is run by Engineering Science, as long as this continues, the others have no chance! Oh, and don’t get me started on SpaceX! He’s somewhat eccentric, but Elon is a genius for making a clear decision that companies that solve engineering and science problems should be lead by engineering and science thinking, not bean counters and fluffy air-head marketers!
Fully with you on this. Sandy Munro (I trust you know who he is, else search for Munro Live and sub, he's priceless) also rants about MBAs ruining the car industry. GM's amazingly successful 🙄 EV program shows we're right on this
You are one of the best tesla content creators I've seen. You get right to the point but do not miss important details. That is a hard balance to strike. Kudos.
I have watched the first two segments and I am anxious for the final chapter. I had heard something about the new braking system but your more in-depth explanation was great! I drive OTR trucks and I am anxious to see the heavy truck industry adopt this technology and finally eliminate the air brake systems. I had thought of the 4 wheel steering tank turn. I compared it to a zero turn radius lawnmower. I think about 45° of turn angle would be sufficient. The most useful aspect of that maneuver would allow approaching a garage or other parking space forwards and then turning 180° before backing in. It is always safer to pull out of a parking spot but many have difficulty backing in. I agree that Elon will equip the Cybertruck with every technology he can find. I have one ordered since November 20, 2019. I can’t wait!!
Pretty early in the waiting queue! Nice! Also, since you;'re in OTR - you probably heard already that Tesla announced they'll deliver first Semis to customer (Pepsi-Co) on December 1st. Can't wait to actually see a Tesla semi in person. As someone who watched the semi launch without a trailer - it's like watching a house take off!
been driving semitrucks across USA last 10 years… ordered cybertruck when it was announced.. when its delivered i’ll retire and pull my rv around.. i’m done with deisel, oil, fluids, plugs, belts, trannys, anti-gel, etc etc... cant wait for it to get into production but this video is helping me appreciate why it’ll be worth it.. thx!
The cyber truck is definitely a different type of truck. Most people can't understand what they are looking at because they haven't been exposed to engineering principles. When I saw that triangle I knew there was rigidity improvement right away. It is not conventional but it is definitely revolutionary. It will change truck design in the industry long term.
I was a young Architect between '79 and '84. Imagining what the CYBRTRK would look like prior to reveal using Tesla's 'snippet' of a section of the design, allowed me to fall in love at first sight of it as it drove across the stage in 2019 My reservation is ~75000. Coming to Oz on 2024 ish
Very impressive! Both your analysis and what the Tesla engineers have come up with. When the fog clears, this design will probably be acknowledged as the best ever. 🤔👌
One thing I don't see mentioned enough. This truck is nearly infinitely rebuild able. So long as the aluminum and stainless are properly isolated, corrosion should be negligible. Municipalities with long term vision towards budget and little regard for style or color will love it.
Very true. This video focused on Exoskeleton characteristics and the first one on technology and features. I'll probably include this in the third one which will focus on manufacturing
I have ordered a Cybertruck for all the reasons you stated and more! Having a stainless steel outer body makes it incredibly tough and scratch resistant off-road so building that dream cabin without power or noisy fuel generators practical...
I have a reservation for CyberTruck. THANK YOU for your in-depth overview of Cybertruck! I have been following, investing and learning about Tesla since 2018 but only today have I discovered your channel. I obsessed on watching 5 of your RU-vid videos in a row! Your knowledgeable insight is of high value and is greatly appreciated. I especially liked your comparison between Henry Ford's Model T vs Elon Musk's Tesla assembly line perfection and their application of first principles ingenuity.
Love Cybertruck. My mistake was not reserving one right away but holding off for three months before doing so. Guess now I will have to wait in a long line…sigh. Maybe they will have done further improvements and bug fixes by then.
I reserved a dual motor CT on the last day of 2019. I don't have the budget for the initial quad motor, so I will be waiting. I think they will offer everyone the option to upgrade to quad motor, and those reservations will get built first. If you have the budget, that's the easiest way to get one earlier. I reserved FSD at $7k, hoping to get moved up in the queue. Now people are wondering if reservations will even get honored at all.
Could you talk about the differences between welding exoskeleton components vis a vis using a break to bend them. I have this image in my head of a big origami machine.
I work part time with a master carpenter and roofer. I learned a lot there. The truss is key to giving otherwise rather weak material immense strength and weight bearing capability (like a roof). Tents also operate on this principle. Bridges of course too. Triangles are everywhere:)
Very interested in hearing about the laser scoring and folding of the body and if the body can be cut and folded out of one flat piece of steel. The speed of building the CT should be amazing and I would like to know if the design lends itself to the "Optimus Bot" being used to string the wiring harness or other tasks resulting in the profit margin being astronomical.
Between serial busses in automotive realms that minimize wiring harness complexity down to a few wires, think about this! With a single sheet of metal, depending on topography and topology, you could easily insert a whole-truck wiring harness into the interior with a single operation for fasteners to the sides of the sheet metal, holding in a complete (or mostly so) wiring harness with all the electronics/lights. By contrast, unibody or body on frame you need to run that through body panels, each of which are made in separate parts, no matter how you slice it. This requires a rather significant number of connection steps in a best-case scenario. It’s possible I’ve messed up somewhere, but between the giant stamping operation of a single sheet of metal, and all the other things, the cyber truck should be the easiest (and thus cheapest) mass-produced automobile for assembly once you have giant presses. It likely has very few scenarios where humans need to be inserted into the assembly process. My formal training is robotics/automation, and I’ve worked on code for implementing controllers for CNC machines and press brakes, so I look at it from that experience: how do you automate things? You optimize topology for anything you can, and this is a truck that’s literally designed to be easily and efficiently bent during manufacturing, but not in the field. I expect it’ll be very noisy around those giant presses ;)
Great video! There is one caveat though to the idea that lowering the air suspension makes reaching into the bed as easy as traditional trucks: While the top of the bed's buttress would now be lower and closer in line with other body on frame trucks, the bottom of the bed would also be lower. The distance from the top to the bottom of the bed wouldn't have changed, still making it more awkward than a traditional truck to reach into the side for a low sitting object. While I wouldn't consider this a deal breaker, I don't think the standard work truck user would fully accept this solution as equivalent. But as you've said in the video, this truck isn't meant to appease all types of truck users! Very impressive piece of engineering.
Yes - but on the other hand, Cybertruck will have a frunk that traditional trucks don't have, so small items that you might otherwise carry in the bed are likely to be even easier to get out of the frunk. There is also some storage integrated into the sail pillars, kind of like what you might find on a service truck.
Chad - you're right about bed bottom going down as well, but it seems that Tesla was aware and took care of that as well. Adding to the points that @@alanlight7740 raised - the audio was finalized when I noticed it, but I added it to the visuals (if you just listened you probably missed it) - Tesla added integrated shoe-tip steps behind the front wheel (for cleaning windscreen), in front of rear one (for reaching into bed) and in sides of rear bumper (for climbing in without ramp - this one somewhat like I showed for Silverado in my first Cybertruck video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Y41rHaTGgWY.html
Actually (besides the toe steps mentioned by the presenter), the lower truck bed means that one can reach farther into the truck from the tailgate end. And actually that’s where all the smaller, lower stuff would typically be loaded. If you forget what you’re used to and just look at this design with fresh eyes, it’s pretty darn amazing IMO. It works...and I predict will be a great deal more popular as people actually start using it and discover its versatility in practice.
This was really good I now understand why the Cybertruck looks like it does. I was told that it looks that way because it has to, but it is much better to know something, than just be told something.
A Reciproction-recirculation axial-tangential fractal Vortex is the relative-timing Form following e-Pi-i numberness-resonance Function.., First Principle Observation. Great Explainer for Engineering Sciencing, thanks.
Another Cybertruck feature that was hinted at: the patent for the onboard computer suggests the ability to sync with an autonomous drone. There's also been recent comments from Elon about making it watertight enough to float. I also think they have something in mind for the windshield wiper that they've been keeping secret, but maybe that's just wishful thinking. Loving these Cybertruck videos, you've explained and speculated better than most others I've seen.
I learned from a friend, long ago, to never allow people to put things, or remove things, from the side of a truck bed. Doing so always cause scratches.
Lol I had a blooper there, pointing to the "video up soon" tweet instead of the "video out" one. Glad you went through anyway. 💯 And just noticed - thanks for the Super! 🙏
@@user-to2rf1rj5v I have watched the video kid!!!! Keep your opinions with you!! There is a reason why people likes body on frame trucks because throes are actually way more capable/flexible design with tons of different configurations for all kinds of applications.
This is a great explainer video on the genius of Cybertruck’s exoskeleton. I had a true “aha” moment about torsional and lateral rigidity, cyber truss and buttresses, so huge thanks!
And having a mechanical trade background I too was worried about the side accessibility of the bed. I didn’t realise the air suspension sorted this issue. Love it! Once again, absolutely awesome vid.!
I used a picture of the Cyber truck overlaid on a scale CAD drawing of my Mercedes Sprinter van to create a scale drawing of a CyberVan with the same angular shape. Based on my conceptual drawing I think Tesla could easily utilize the design characteristics from the Cybertruck to build a virtually indestructible Cybervan. I like the angular futuristic looks and would love to have a rust proof stainless steel electric van with armor glass windows! I’d be the 1st in line to order one.
I want the cyber treatment for EVERY vehicle. And that's just for the lack of paint. I am so, so tired to the delicate skin of my vehicles. With a stainless skin, I can let it patina. I can polish it if I wish. I can wrap it. I don't need to work about dents and dings. The rest of the advantages that you detail here are awesome, and clearly important for a truck. The problem as I understand it though: This sort of treatment only really makes sense for a "truck" and other more rugged vehicles that are going to be big and heavy anyway. What are your thoughts about this being applied to more efficient, much-lighter-duty passenger vehicles (like the 3 and Y and Tau?). I WANT a stainless, un-painted skin!
Great explanation of the exoskeleton and elimination of dead weight. Since the body is the frame, I wonder what insurance companies will do in case of fender benders. Will this result is CT being totaled easily because the "frame" is bent?
Great job! You've proven yourself wholly trussworthy as a premiere explainer of all things Tesla and its superior engineering. I'd love to hear your analysis of the Aptera as well some day. I think Aptera should get more love from Elon as they're making a very efficient EV while maintaining a fairly high degree of safety, albeit probably not Tesla level.
Part of the benefit of a standard bed form that other trucks use is that the owner can buy and use standard equipment in the bed. Such as tanks, salt spreaders, job boxes, and so on. Or the ability to remove the box and put on a custom box for specific work.
CT is likely to be the closest any ordinary person can come to owning something that resembles a product from SpaceX. Everything about it, other than the four wheels, will seem so otherworldly that even if you hate pickups you won't be able not to be in awe of the CT.
Awesome illustration of sharing the load especially to someone whose been sorta on both sides of that picture and going back into both after retiring from dad mode.
25:55 "...and I haven't even touch manufacturing aspects...": That's the elephant in the room. How do they fuse the stainless steel panels together? And how much do they weight?
LOL yes. With me it was the other way around - As a car guy I knew the term from cars, and only found its roots while researching for this video. Some beautiful flying buttresses in old churches. Smart engineering done ages ago
Excellent, Yes I also saw it’s potential as an Automation/Robotics manufacturer for 40 years. Geniuses created this. The aftermarket for this will be Insanely prolific. The 3mm ( ~1/8" ) thick toughened (work hardened) Stainless Steel can host Body Panels attached with Pem Nuts to alter the Look. Using a Wrap to give Color. Color changing Wrap for Military + Hunting, send it away while you Hunt, call it when ready to move out. Body Panels using Vacuum formed Carbon Fiber (or Kydex plastic) will be a Cottage industry since it can be done in a Garage even. Most disliked the Looks, while I was loving all those FLAT Surfaces to Attach things to. OK, To make a Panel, Make a wooden box, make a "plaster form" in the bottom, drill 1/16" holes through the form to pull a Vacuum, lay a sheet of Heated Kydex on top of box, pull Vacuum- Done. Pretty easy, the flat mounting surfaces makes this a lot simpler. The Army had a V-100 (Chrysler Hemi powered) Armored vehicle that used a similar Exoskeleton of 3/8" ? Aluminum, Vietnam 1970 (my Ride), could deflect bullets/ RPG’s because of the angled panels, could also Ford a River using the Runflat Tires to move it, I expect CT to be able to do this, it was the fastest vehicle the Army had at 70 mph. Special Forces will want this CyberTruck. Cheers from San Diego
Elon was Inspired (at least in part), by the CADILLAC GAGE COMPANY - V-100 Armored Vehicle (on YT), Vietnam 1970 Screaming Eagles 101st. ABN. Not affiliated with Cadillac Car Company. He probably had seen one. Cheers from San Diego
Regarding the Buttresses and Suspension: on a worksite, time is money. If CT drops rapidly and low enough to negate the buttress inconvenience, then fine. If not, then CT has lost a prime function of a work truck. Remains to be seen. We still have to see how far we can tow a mini-excavator or loaded dump-trailer too.
Thus was intentional. Both keeping the manufacturability aspect for another video, third in this series (this was #2), and trying not to repeat too much what people already know (which will be hard for that 3rd one, lol)👍
