But At What Cost? Tesla Cybertruck Door Teardown

[@henrybrandt1057]

Carl is a natural at teaching. Thank you for another educational lecture.

[@MunroLive]

Thanks for watching!

[@SuperLala33]

Very clear and precise, great explanation. Best on this channel yet i must say :)

[@tooljack4439]

agreed. Great explanations from him.

[@mousetreat]

Keep nerding out! That's what we're here for. I learned something today!

[@TylerATX]

Yeah I'd say if a video is an 18 minute breakdown of door panel design considerations, we're all already in a nerd moment

[@WilliamDye-willdye]

His explanation at 11:30 of injection/casting shrink marks is much more concise than anything I've seen before. I was messing with finite element analysis, but all I had to do was draw a circle.

[@ralanham76]

❤ 3.14 is the magic number 🤣

[@XzzVttll]

well, thats the mistake on your side. you jumped right away on level 100 and didnt pass trought level 1.

[@Dalisu87]

Carl is so good at explaining complex stuff, from his cadence and giving clear examples wrapped in controlled nerdy passion.

[@poporbit2432]

This is exactly why I watch your videos. Learning this level of detail is so value and is unique to your videos.

[@jgramsey]

Title of the video could be, "Managing design trade-offs" excellent discussion of engineering trade offs!

[@teodor4ik183]

At this moment i am trading with a lot of variables and cant get clue which way is better... 😂

[@GoofyChristoffer]

Never be sorry for nerding out here! That's what we're here for!

[@MunroLive]

Amen

[@regolith1350]

Holy Shrink!! Who knew material shrinkage could be so fascinating? When he flipped the plastic panel over to show the hexagonal indentations, it all clicked. That reveal was a nice touch!

[@larryellison1788]

Very clear and concise explanation. Great job. I am amazed at all of what the Munro group does and it continues to showcase the advanced engineering that goes into Tesla autos.

[@ianlevy4227]

carls videos are some of my favorite, you can tell he has passion for what he does

[@knightkrew]

0:55 I believe Tesla is opting to include individual door control modules vs integrating them into the body controller as a test of their "Unboxed" process in a production environment. This allows Tesla to test / homologate individual doors before installing them into the vehicle. Once all the components are integrated into the vehicle a final integration test can be performed by the vehicle itself to ensure everything is working together. This approach is similar to how NASA tests new rocket components where they fly the new parts on old rockets before they fly them as an entirely new rocket. What do you think?

[@1968matrix]

And do not forget the speaker integration... it eliminates two more wires....

[@ikocheratcr]

It also simplifies the cable harness in general. One connector that at most has 8 wires into the door that need to go along the hinge. 2 for GND/+48V, 2 for CAN, 2 for digital audio, and 2 for the SRS. Only the power pair is "think", but again at 48V current 1/4.

[@XzzVttll]

why do you have a need to use this type of grammar "test / homologate"?

[@coreyw427]

They’ve essentially discovered the process German manufacturers have been using since the early 2000s. Well done 👏

[@TheAefril]

That is a brilliant analogy using rocket design with old tried and true components (which historically, you know are proven) in the new overall rocket design. Good observation.

[@JigilJigil]

Another amazing video by Munro and Carl.

[@MunroLive]

Glad you enjoyed it

[@caladanian]

The i3-design to showcase the material was transforming a bug into a feature. Smart design 😎 …and I actually liked the surface in the BMW i3 doors and front panel.

[@alanmay7929]

They also did that while using mostly recycled and more sustainable materials! Why doesn't tesla copy that?

[@okharren]

Great video, love the "shrinkage" explanation. 😂

[@patmcdaniel2016]

Loved the nerd moment, It was very informative.

[@MunroLive]

Glad you enjoyed it!

[@neilmckechnie6638]

Top presentation. Clear, precise and to the point.

[@mjp0815]

Hey this is exactly what I come here for. Next level integration, what a great team at Munro.

[@alanmay7929]

It's not next level integration lol!!! Bmw did that while actually using recycled materials and much sustainable ones a decade ago.

[@johnmanzer9717]

Love watching Carl videos! More Please!!

[@johnchristopher20]

Note to Tesla: what good is an emergency release that is hidden? Make it a feature, like the RESCUE label on a jet fighter.

[@pepstein]

I think this is a rear seat door, so you have to consider child safety. If child locks are enabled but the child can open the door anyway, that would be a big problem.

[@jackcoats4146]

I love the overall systems approach. Each item is important, but the overall system is still the point!

[@alanmay7929]

Just like every other manufacturers lol!!!!

[@Simon-gk9ug]

Awesome vid as always guys and props to Carl for his knowledge and geek moment 😅

[@CardanoCastellano]

14:04 So Carl provides this amazing explanation but at the same time says "sorry for that long explanation". Thank you...again, great explanation

[@sreville]

Almost skipped out, but he drew me back in with his enthusiasm for the craft. This man is an absolute joy to learn from ❤️

[@redcrumb]

thank you for the explanation!

[@MunroLive]

You're very welcome!

[@eried]

This is one of the best guys explaining stuff in Munro, more videos please!

[@danharold3087]

The frameless doors on the CyberTruck a style choice. The door controller module enables Tesla to assemble and test the doors independently. A bit of the unboxed system influence. Having fixed a few window regulators I love the huge access hole in the Tesla door.

[@pasad335]

Using the words 'Tesla' and 'test' in the same sentence is a joke. Everyone knows they use their customers as the testers.

[@edwardhackett-jones8126]

@@pasad335anyone who actually knows what they’re talking about knows that you’re wrong in that. Every vehicle is constantly performing its own tests on itself as it is assembled on the line.

[@danharold3087]

@@pasad335 Tesla continues to collect data after the car is sold. This helps Tesla understand how to improve the car. This is an advantage. Yes people pay to help Tesla test FSD. Neat trick I doubt we will see that happen again.

[@chrisgraham2904]

Having just replaced a window regulator, I agree and love the huge access hole of the Tesla door and the simplicity of swapping the module. However, if any minor component fails in the door, I suspect a full module replacement will be the only available repair solution. Imagining the cost of the Tesla integrated door module is scary.

[@danharold3087]

@@chrisgraham2904 My expectations are that we will see a ecosystem of 3rd party repair parts build up around the CyberTruck as they come out of warranty. That is dependent on it continuing to ramp.

[@billhaley8873]

Excellent video comparing trade offs for weight and aesthetics. I appears that while the stainless steel is a design feature it may not be as big a structural feature as originally believed. How much weight could be saved by redesigning the skin to use either steel or aluminum sheet metal. The door is a good example. It would not look identical but you might save hundreds of pounds which translates to higher range or smaller batteries.

[@ChristianKurzke]

This ammount of optimisations is really only possible because of vertical integration. As he says in the video, in traditional manufacturing every team is only incentivised to optimize their module. You need a lot of collaboration to create a global maximum optimization where you can intelligently trade door panel features against battery range. Well done, Tesla!!

[@alanmay7929]

Nonsense!!! Other manufacturers actually gives you choice! Other manufacturers literally makes some cars with almost 100% carbon fiber.

[@alanmay7929]

All tesla interiors are super boring black or white, very few color choice or let alone materials! Bmw did the absolute perfect vertical integration in 2013 with the i3 while using mostly recycled and more sustainable materials, nothing will ever top that even Munro says it!

[@MikaPopp]

So Cybertruck's door is heavier and more expansive than Ford's. Where is the improvement again?

[@WarrenLacefield]

@@MikaPopp One improvement might be safety, when some other vehicle crashes into your side of the truck.

[@betamax5674]

Always learn something new with Carl, great information!

[@MunroLive]

Glad you enjoyed it!

[@ForTheBirbs]

Please keep nerding us out Carl! Love it. Cheers

[@InfinitelyQurious]

I'm geeking out and loving every minute of this, you guys. Keep up the great teardowns. Awesome stuff.

[@johnross6314]

Excellent content! Keep up the high energetic spirit growing.. To a Sandy level. We need many “Munros” barking out the reality… with insight and vision.

[@carloslaue1236]

I think they hide the rear emergengy release under a rubber mat because of children... You don't want them physically being able to open the door without any latch... Maybe a mechanical latch with a mechanical lock would work better but then good luck getting out of any mechanically child-locked vehicle.

[@techiheed1845]

Got to agree with comments. Passion in every word of application. Quarter past ten in the morning, banging that out was ace.

[@ken830]

It's fun to learn from Carl!

[@tega85]

A++ video Carl! You are promoted to be the new full-time Munro Live teacher. When in doubt, should you have another nerd teaching opportunity moment, the answer is always yes!

[@Gelp]

I love Carl's videos, so clear and makes potentially boring content interesting for even me who's not an engineer 😁 Munro is great too, but for very different reasons (raw passion, and different knowledge and experience )

[@clovisdma6504]

The shrink explanation was perfect. Thanks for the video.

[@rowansinger3876]

That was an incredibly useful nerd moment, I understand so much more about what I am seeing in various plastic moldings. Thank you for going into it!

[@coberfranc]

Carl is a STAR!!! Love his insight.

[@MunroLive]

Superstar!

[@MooseOnEarth]

When you see Carl, you know it will be good.

[@alittleofthisnthat5665]

🤔...Carl giving a masterclass of saying this sucks with directly saying it sucks, well done and thank you for your silent honesty

[@davidherbert5027]

I was about to write that Carl has an excellent presentation style, and then I saw that Henry has already drawn attention to this. Kudos Carl. I look forward to seeing more of your discussions.

[@evanlacava9213]

Don’t apologize for a nerd moment, we love the insight. Thats why we watch these videos 😎

[@TheAefril]

The Munro channel is full of great pearls of wisdom compiled from many life-times of engineering experience.

[@davidstockbridge]

Carl, thanks for explaining the details. Suggest that you stage your demo space ahead of time, so that you're not stacking assemblies on top of another brand's assembly. Remember to define your terms for those unfamiliar with car design.

[@gregw3444]

A Carl video is always a great video! Interesting start to finish every time :)

[@scdi12]

So much helps me to appreciate good engineering planning and my cyber truck as well. Thx

[@antoinepageau8336]

Forecast volume and market segment will also drive many design decisions. Great video!

[@robertrobertson5120]

Thanks Carl for the enlightening overview!

[@CharlesLogstonInTexas]

That cover for the inner door panel is a terrible choice. There is a reason trucks have durable plastic on the lower side of the inner door panels, especially the rear door. It tears easily, I found out the hard way, a very expensive mistake on my part.

[@badgerdad777]

I learned a few new things here. Well worth the watch.

[@Chase_is_a_race]

Overall, the cybertruck seems to be a well put together machine, going based on these teardowns.

[@themogget8808]

I hate rimless doors on non-convertable vehicles.

[@jmirodg7094]

Thanks Carl! Extremely instructive.

[@Chas_Reno]

excellent love the details

[@JT_771]

Great info; thanks!

[@nicecriminal6150]

Is this why the door panels come off when you slam the door?

[@wtmayhew]

I’ve seen surface pull back on exposed parts quite a few times. Some engineers don’t care or were ordered, “just do it anyway.”

[@compu85]

The ford window regulator clips remind me of the plastic clamps VW used on the 99.5-05 Jetta and Golf, which were very failure prone. The plastic gets brittle when cold, breaks, and the window falls into the door.

[@franciscoshi1968]

I am converting a vehicle to electric and I am adding many features that the vehicle didn't have before. The solution has been to add a door module to each door that communicates via CAN bus. It makes the wiring much simpler and allows for more features to be added later without modifying the main wiring. I only need to run 4 wires thru the entire car. Much simpler than the original wiring with more features.

[@lawrencebrillon6176]

Thank you for needing out, Carl!

[@Roberto-mr9mv]

Nice to see how simple and uncomplicated the door is and easy to fix yourself. Very cheap too.

[@justme_brentg]

Wow, am I turning into a plastics nerd too? This is fascinating.

[@nerdwatcher4273]

Excellent breakdown and explanation!

[@MikeWazowski42069]

Another key fact about the Cybertruck door is that it break if you slam it just a little bit as shown by Whistlindiesel

Conveniently left out the rust problems and the fact that everybody is wrapping their stainless steel Cybertrucks. I can understand why people like no frame on doors, but I prefer framed car doors.

[@darpompie4354]

Agree... Kind of defeats the purpose of using expensive and heavy stainless steel. They could have been out 2 years earlier and had a way better product if they just used aluminum. Stamped light weight panels and nice glossy paint options.

[@fredbloggs5902]

There isn’t a ‘rust problem’. Yes some people have reported small discoloured patches, but these buff off easily as they’re just a surface effect.

[@zachlafond2652]

My kitchen sink is stainless..no rust and i wash dishes all the time.

[@monkeystealhead]

@@fredbloggs5902 All steel rusts, whether it’s stainless or not. The surface effect is rust. Stainless steel rusts much more slowly and probably won’t rust throu within a car’s lifetime. However, arguing that it has less weight because it doesn’t need paint, and then everyone puts foil on it, doesn’t make sense.
