Peeling Back the Layers: Tesla Cybertruck Rear Body Panel & Castings 

I like when Jordan is in the show, very knowlegable and good with his explanations , please have him on more.

I'd like to see a deep dive into automotive adhesives which are used so much now. Another great, informative video Munro team!

I've been waiting for this analysis and you didn't disappoint. There is styling and there is engineering. Most people respond to the styling and don't see the engineering behind this vehicle. That is the real story. Thanks, Munro.

Sandy, Talking about Easter eggs, have you found 'Hi Sandy' !?!? Tesla Team left you a beauty!

Cattywhampus has got to be one of my favorite precision technical terms surpassing cockeyed by miles🤣

cybertruck and cyberhammer reliefs in the stamping were a nice easter egg!

Sandy & Jordan are the best! Understandable and informative-a rare combination of knowledge and personality that make engineering fun! Thank you!

Hilarious the way they talk about how simple the alignment of the components is in the Tesla compared to other cars, while at the same time ignoring Tesla's legendarily inconsistent panel gaps.

THANKS SANDY,JORDAN, AND THE MUNRO TEAM,AND 3-D FOR SPONSORING THIS 👍TEARDOWN 🧐💚💚💚

Jordan is a keeper! Don’t let the competition poach this dude.

"Looks like a banana, drives like a dog". Another amazing Sandyism!!!

The flutes/channels are for drainage to prevent water/dirt buildup and ultimately prevent corrosion. They obviously have nothing to do with E-coat drainage in this application, since the panel has already been ecoated prior to being bonded to the stainless exterior.

E-coated inner skin would very likely be dried and cured before bonding to SS outer skin, So it would be expected the drain holes are for condensation between panels (weep holes).

I really like the Sandy/Jordan combo. Well presented

Those escape paths are also for water drainage

Okay, I paused as soon as I saw this, a 9:59 there is a dent shaped like a Cybertruck right in the middle of the panel backing. Do they ever mention this in the video? Edit: A little bit later, you can see a hammer shape in front of the CT, like it's dropping onto the front of the truck.

Thanks Sandy and Jordan. Very technical, yet strangely entertaining - The Naked Cyber Truck. A guy named Desmond Morris wrote a book in 1957 that was also technical yet engaging called "The Naked Ape" It was a hypothetical tear down, inspection and comparison of Humans. Way to go Munro Live!

Love how he used catywhompus as technical speak 😂

The "flutes and gaps" look like moisture drains to me. The e-coat panel is probably already dry when attached to the stainless skin. Did you catch the Cybertruck and hammer silhouette stamped into the inner panel at 9:55 ?

"looks like a banana, and drives like a dog" is something I'll never forget

Steel on the inside of the stainless steel panel makes me wonder about future corrosion. Dirt, mud, salt can get trapped up inside those pockets along with moisture and cause rust inside the panels. I've seen plenty of old trucks rust out from similar seams.

Awesome! THANKS FOR VIDEO!

many thanks Sandy n team

Love you guys. Thanks!!!

Another great video presentation. Really like the way you welcome and embrace the discussion of what your seeing and analyzing. You and Jordan did a great job. Thanks!

I love your tear down videos. A quick question though, at the end, you said that you will be putting the side panels back on and doing torsional testing. We saw one corner of the mild steel stamping that was peeled up, and you said you wanted to peel up some more. Won't this compromise the torsion testing?

"eXoSkLEToN" my ass lmao

I love how your videos feel like they are something i could do at home. That may not sound like a compliment, but your just a team of folks specialized in something other than making videos and advertising sales. Its nice.

Thanks! Yet another example of why I subscribe. All the best

Thanks...well done as usual!. Addressed a lot of questions. Looking forward to your continued 'big picture' assessments.

Awesome review! Both of you are great! Thank you

Great video gentlemen! Wow- the engineering on this thing is just next level! Thanks- I can’t wait for my Cybertruck!

Those spot welds would need over 500kg of clamp and more than 10k amps of current.

In my opinion, the “flutes and escape paths” have nothing to do with the coating process (the coating is done before the stainless steel plates are glued on, which means there are no enclosed cavities anyway). To me, these areas look more like measures to avoid draw creases: Material is “used up” here that would otherwise form creases in the drawn part.

Thanks for sharing these insights on the Cybertruck structure and assembly methods. Looking forward to seeing your results for body stiffness. Thanks for sharing.

Thanks that was cool.

Bravo guys! The pace, content, camera angles, ect ect are SPOT on in this episode. And as always, THANK YOU for your continued efforts to share and educate the world.. content like this is so critical, especially as your videos inspire the next generation of engineers!! #masterclass #teardowntitan !!

Thank you!

You guys are miles ahead of the teardown reviewer on Autoline. Great video. What was Sandy's reaction to the Easter egg Tesla left him on the circuit board?

making manufacturing great again!!!!! thanks sandy and crew

It would be great if you could do a video on the nodal testing. Just to see how it's done.

nice!

Maybe the near center crease spot weld was to straighten the stainless panel. Remember the early days of the truck it used to have a ripple in the stainless around the wheel arch when you looked down the vehicle (maybe a pinch point and warped the exterior). Now, of course this has been rectified.

Very infomative video !!! I wonder how much of the current casting could be reuse without making too much changes, to make a minivan with 3 rows or an utilitary cargo van with 2 front seats and a large box area, like an Amazon Rivian delivery and maybe with a slidding door?

@MunroLive A deep dive into the side doors will be tremendous. I remember the Tesla engineers showing how the inners were laser welded to the outer around the perimeter without discoloration of the stainless.

Great explanation for us novices! L°°king forward to more insights. Cheers from New Orleans

How much does the the whole panel assembly weigh?

Have been watching your tear down vedios. This is one of the best one. Now it is clear how everything fits together and you have done a great job explaining how tesla achieved their GD &T.

I was so excited about the Cybertruck for the past 4-5 years of anticipation. Love what Tesla engineers have done. The end product is not as great as the great parts and pieces you would expect...fairly small battery for a truck which results in not great road trip ability or towing range, god-awful visibility issues, and now with Rivian's refreshed R1s, lots of tech improvements and manufacturing improvements which maybe Sandy or Sue had a hand in? 380-420 mile range, new motors, etc...Rivian just took a very good truck and made it a great truck. So the excitement and promises of the Cybertruck have faded. I'll take a new Tri-Motor Rivian.

Question to the Team -> at 11:55 you guys talk about the pros of laserwelding -> are the sheetmetal parts precoated / coil coated with zinc?

Wish all this effort when into a mass market model 2.

Tesla linked together with Spacex definitely packs a punch. I just saw some thing saying space x wants to be able to build one of those stainless steel starships every day! That’s the kind of production goals that creates mind blowing technology.

What’s the purpose of all the dots on the tear down? Something to do with their digital scanning?

Great content as alway! At 15:55 Challenge to Jordan to say “parry wampus” 3 times.

What about the massive vertical welds from the side casting to the cabin? I have never seen welds so large!

Given the separate gigacasting and the side raiser castings, what are the odds that Tesla might release an "old school bed" work truck? (I don't mind the triangle, but for some work application as well as truck bed campers the triangle might be prohibitive) - seems like it would be a fairly easy change... maybe on the entry level CT - it would save Tesla quite a lot of money skipping the cover as well as the added stainless steel cost for those large sides

I’ve asked before but the rack weight is super disappointing, what are your thoughts on the 440 lb across 8 points

interesting rear fender, so much material and especially space. It appears Tesla needs more stiffness than is available from the rear casting. this almost like the exoskeleton Tesla wanted back then, but I guess thicker stainless steel is not worth the expense and additional weight.

Is that casting&metal part complimentary to the stainless exo skeleton? I get a bit confused.

Are the two parts electrically connected somewhere? I think the glue is isolating.

Perfect!

Even though it has a stainless steel exterior, will it be rusting on the inside?

Id their is a middle layer between the outer skin and the casings, why is the outer skin made out of steel? The only advantage I can see is eliminating the need for paint, other than that, it's harder to stamp, harder to keep withing tolerance, and heavier. What if the outer sking was made out of aluminium? How much would that save/add in costs? And weight?

409 stainless is magnetic IIRC, also not far from cost of mild steels

10:50 why wouldn't you zigzag the lazer weld instead of a straight line so you get the strength in both directions (which was implied with the spot weld)?!?

Is it possible that they can further reduce the parts in the rear casting?

One question I always have when you guys do analyses of Tesla cars. And especially the cyber truck. Why are they not using magnetic olie suspension ?

A great deal has been made about "The truck that won't rust" but using steel stampings to carry the stainless steel skin feels, to me, like saving up trouble for the future. I hope the E Coat they're using is as good as it gets, it would be a crying shame for the Cybertruck if it became renown for being a rotten egg: Strong shell but stinking inside!

Excellent info 👍👍

What are those white dots??

And as is evident on this video; The Cybertruck is mainly anything but stainless steel. A lot of stainless, but mostly regular automotive steel and aluminum.

The Speech Lessons have definitely improved Jordan's briefing skills...

wow they bond it with MMA + PU hybrid adhesives

I love how elons team is rethinking engineering! I love how one of those indents kinda looks like the over all shape of the cyber truck.

E-coat, or electrophoretic coating, is a high-tech process that uses an electrical current to apply a protective finish to metal surfaces: 1. Immerse The metal is submerged in a water-based chemical bath containing paint particles, resin, pigment paste, and co-solvents. The water is de-ionized to remove conductive ions. 2. Apply current An electrical current causes the paint emulsion to condense and form a coating film over the metal. The coating can be 0.1 mm thick and made up of many layers. 3. Cure The metal is placed in a bake oven at a minimum of 375°F for at least 20 minutes to cure the paint.

What are all the dots on these parts that make it look like it’s filming motion capture?

We don't need to hang any hats on the exoskeleton thing. This is an evolving new method for building vehicles.

I'm not totally sure , bu the panel showing laser welds appears to be laser welded to the outer, stainless, panel. I am sure that Tesla had problems with weld "blemishes" on the stainless, visible panels - and they went to some lengths to eliminate these - maybe laser welding (very controllable) helps in this regard....

Also, Something no CT tester has ever mentioned, Does it have the same armored glass as the CT in the unveil!!?? YES/NO

13:30 SPRs?

Sandy, here's an episode you can record and post... What would OEMs look like today if they had adopted your ideas? in the freakin' 70s for god sake. and what would the world look like today?

I want to see the ridgidity test please.

I’m sure it’s been explained before but what are all of the white dots for that are placed all over the place?

What are all the white dots all over everything?

What is the white holes everywhere

Presumably, if someone dents the rear fender, this whole assembly has to be replaced as a unit. Bondo and paint isn’t going to do you any good at the body shop.

Easter Egg image of Cybertruck profile at timestamp 10:18.

Does the stainless steel add any structural value?

Sandy , can you get a hold of the new RAM and evaluate the Truck? Some say the body has to COME OFF the Chassis to do major Engine work, like change the engjne or overhaul it. Thanks

"dead nuts" ... "cattywampus" ... legit engineering terms being used

Tesla stocks should be 450 a share plus

Excellent video gentlemen.

Why was Cory Steuben fired?

Gotta love the F150 ad that YT attached to this video. R&D would have been a better allocation of those resources. 😆

Sandy returns to a Tesla video 🤔, not a BMW or anyone they want to remain on positive terms with despite their unimpressive performance. The PR team is a strong tell tail sight.

What kind of corrosion warranty. Vw has like 12 year ,unlimited miles...on a $45k vehicle

👍

I was hoping for a stainless steel truck, not a candy shell. The shape is cool, as well as all the advancements in design and engineering. But the Cybertruck is not what I need. I'll be waiting for an Aptera. Hopefully it can ford 8 inches of water without motor damage or floating away, as I have to cross a creek to get to my house. Otherwise my F150 will have to do until batteries cease to be the bottleneck.

The Cybertruck underpinning are in my eyes more aesthetically pleasing than its actual exterior lines. I don't think this design would stand the test of time, it's aging badly already
