[@DavidChatenay]

@21:32 this is such a key insight, and one that applies in many industries and endeavors. It's something I see all the time in my job (software engineering): designing a system that works is easy enough. But keeping it simple, efficient, and flexible enough that you can re-use it and update it later, that's hard work. It takes a lot of thinking and experience. On the outside it will look obvious and intuitive and elegant, but to get there is rarely straightforward or easy.

[@joe2mercs]

An exceptionally educational and informative summary by Carl, I liked the Taco Bell reference with respect to door linings. The Kia front door lining car is really well thought out and implemented. I hope that the window actuator cable is stainless steel as when corroded window cables snap they are an expensive repair. The Cyber truck has no framing to the doors and so the extended steel window guides are perhaps a necessity to maintain alignment of the glass.

[@suggesttwo]

13:35 That's where road debris hits the doors. Rockers also get hit a lot too.

CARL: you did it again! I came to video thinking "Door dissection? Really? Who cares!" At video end I'm thinking "wow!...fascinating look at behind-the-scenes design and implementation." I'm a bit surprised the Tesla team seemed to deviate from their usual "first principles, less-is-more" approach. Wonder if Tesla took a time-saving short-cut with first gen CT design in order to get the truck out to market, which they intend to improve and fix next time around? Well done! Thanks.

[@t123a698]

Ahoy! Carl is back.

[@johnpublicprofile6261]

It struck me that the style of thinking, analysis, and design seem very similar to how I approach the computer code that I write and maintain. Concepts such as "1st principals" can be applied to any type of engineering or activity.

[@BruKfu]

Great Guy

[@antibrevity]

100% agree about the plastic cladding. I call this "Pontiac cladding" as that brand made some of the ugliest vehicles known to man in the 90's by covering them with trashy plastic cladding; back then suspected that their target market was trailer parks. Perhaps some buyers like that crap, but I *far* prefer full-metal doors where you use the car's shape to provide styling. However, reviewers do complain that cars are "plain" when they don't have tons of cladding, so I kinda understand why manufacturers do it, but Tesla had the right idea with it's "plain" exterior designs and I sincerely hope that they don't start adding plastic crap to the exterior of their vehicles in the future. I live in a horrible section of the Rust Belt and find that my vehicles always start rusting under or around any plastic cladding. I hate plastic cladding.

[@23billd]

Hey Carl, that was great! You really know your stuff! I'd love to see a similar interior analysis for the Mazda 3 hatchback that I rented last weekend. It looked good for an affordable car. I'm always more impressed by designs that can meet both cost and perceived quality objectives.

[@lifeisfuneh]

Love to listen to Carl's opinion! Can we get segment on design efficiency versus reparability?

[@jmaldo36]

The clamps on the glass are different to the F150 because of 2 things, the construction of the glass, and supplier... i reckon the KIA has laminated which doesn't allow to drill a hole in to the glass for the quick snap, so they need to bond their brackets to the glass and PHA which is the likely supplier for KIA doesn't have much experience with quick snaps, that's more Brose style window regulators.

[@Ficon]

Correct, Kia front window glass is laminated (back windows on higher trims too).

[@Ficon]

I hate aluminum doors. Audi doors feel super cheap and they pick up dents like crazy and the dents are really expensive to repair.

[@tesla_tap]

Strange, I've had aluminum doors now on 4 cars (3 Teslas, one NSX) and never have gotten a door ding and they feel as solid as my old Lexus. Sounds like the skin maternal Audi used is too thin or you are unlucky with people really slamming their doors into your car in parking lots. Normally when using aluminum, it requires thicker material than steel, yet can have the same strength while being lighter. Using the same thickness aluminum as steel would not be wise.

[@Ficon]

@@tesla_tap Yeah I think they are really thin. Pointless as the e-Tron still weighs 5700 lb. I would take steel EV9 doors just for the door feel.

[@tesla_tap]

@@Ficon Yikes, that's about 1000 lbs over the Model S. Prehaps the Audi was going to be even heavier, so they thinned the doors even more than they should to save a few pounds. Those EV9 doors look heavy duty!

[@Ficon]

@@tesla_tap It’s a much nicer and quieter car and not built on a dedicated EV platform.

[@petersilva037]

Is it possible that the tesla door assembly is just re-used (with a different rail) from model 3/Y or that that is the plan for the future? 1 door unit for all doors in all models?

[@SkaBob]

I think the range gained by power retracting flush door handles would be nearly 0, especially on a larger heavier SUV and isn't worth the extra cost. One thing I like with the Prologue is the normal non powered door handles. Lower cost and no problems in areas that have snow or ice when the handle getting frozen in place.

[@cccaaa9034]

9:00 My guess is the metal rails on the cyber truck would be needed for additional window stability because of the thicker double glass pane, lack of door window frame and because of the original "bullet proof" glass in the finished concept vehicle. Am I wrong?

[@journeyman291]

Going to be really easy to add Dyna Matt to the Kia door for ones stereo upgrades. My Toyota Venza was constructed very similar, including the rear door.

[@kevinlucas8437]

Great info !!! I understand that there are different ways of achieving the same build, but the different build processes on the doors of EV9 are a little confusing on why they chose 2 methods.

[@dantepastro8465]

Great review!!! Why not making the door that includes the widow module made of steel and remove the outer steel skin of the it's outer body? I think GM's Saturn division tried this decades ago.

[@jason_kawk_35y35]

and it might be interesting to monitor changes between different model years. As cost saving is critically important, time to market is also equally important to release product in right timing. To meet certain timeline, they might skip machining of certain components or reduce it. But they complete or improve machining for next model year to achieve cost goal.

[@ToddNorthrop]

Wait, I don't remember seeing a Cybertruck door video, what is Carl referring to? It would have been great to see the same number of videos dedicated to the Cybertruck that Sandy had with the Model Y, but the Cybertruck content has been very sporadic. I would have thought there would have been dozens of them! (I would be there for that!)

[@coriboririyamehistunaresma7730]

You combined the advantages of 2 different Tesla parts and compared them to a 1 different vehicle, I think this is unfair

[@wtmayhew]

Thanks Carl. GM gets the short stick for being old school, but looking at even the 2017 Bolt EV, the hood, fenders, doors and hatch are aluminum and there are advanced composites as well. GM has also dealt with bonding aluminum and steel in the body structure. The new kids on the block manufacturers get press, but GM quietly incorporates similar technology. Too bad GM doesn’t have a charismatic promoter like Musk.

[@cengeb]

Audi pioneered lots of aluminum use in lots of stuff...over 20 years ago, audi aluminum hoods,doors frames,braces

[@wtmayhew]

@@cengeb Audi deserves credit, thanks for mentioning that.

[@jamesengland7461]

GM has pioneered countless automotive techniques and materials, but has always lacked singular vision, usually gets the bugs worked out right before they cancel the car, etc. They pioneered most of the basic elements of the modern EV, but never put them together and decided to conquer the world. Those employees, though, went to Tesla.

[@wtmayhew]

@@jamesengland7461 Exactly. GM has some of the deepest knowledge of battery technology and battery chemistry, having worked on batteries since the 1960s. One of their earliest examples was an electric Corvair about 1966, just a one-off demo. Next was small number of G series full size vans in the mid 1970s. We’ve all heard of the EV-1 (originally bearing the poorly chosen name, “Impact.”) which was made from quite a few Saturn parts bin components, The EV-1 platform had several other versions in very tiny numbers win Diesel power plants, etc. GM has electrified things other than automobiles over the years, so there is probably some institutional memory, but with the reorganization after the 2009 bust, who knows how much was retained. It seems like as soon as GM gets good at doing something they shoot their own foot by quitting success.

[@chrisschenk5513]

Carl, there is an elephant in the room that you aren't addressing. You are comparing apples and oranges. The tesla window does not have an upper window frame, which guides the window and keeps it in place while the car is at speed. The cyber truck and all teslas are frameless windows and need to be held in place with robust guide rails to keep the windows tight against the rubber seals at speed. I thought that you would see the doors are not even close in design and application.

[@rjbiker66]

Cybertruck has frameless windows

[@celeron55]

That's definitely one reason to have the stiff metal rails, very true!

[@aninoutski]

The steel bar in the door, is it not the side impact reinforcement bar? Volvo was doing something like this long time ago.

Question? Steel Doors vs Aluminum Doors vs Stainless Doors, which 1 costs less in the long term or a MASS produced door? Adding a external weight to a door would make the Cost go up. Regarding that TESLA door module or modules: ISN'T TESLA still a BABY automotive company when you compare them to KIA or FORD OR GM. Instead of screws on the KIA, could you use snap in clips? TESLA could be eliminating FASTENERS..... Could be legacy costs for KIA....

[@SublimeSimplicity]

Awesome break down. KIA seems to update/redesign their vehicles every 2 years. Tesla much much less frequently. Tesla focuses on manufacturing cost reductions every year. KIA brings a different look almost every year. I think that difference dictates the construction/assembly, bc you can't build highly efficient/custom lines if you're constantly changing the design.

[@waynerussell6401]

Watch a few Joe Justice videos! Tesla constantly redesigns - dozens of changes on a line a week! Their lines are the most efficient - 39 secs out pops another car. The 50 year old Toyota way has been long superseded.

[@desobrien3827]

Hi Carl, you really are one very intelligent man & is a great presenter!!! However in Australia...Lowest spec EV9... Drive Away $108,326 AUD Who are you kidding pulling apart an overpriced family car at say 40% depreciation in 1 year...I would buy the ICE Aust. equivalent Kia Sorrento $57,100. In what world does a Kia EV9 make sense! It does not!

[@ouch1011]

Since the EV9 is pretty low volume and Hyundai/Kia has many more similar vehicles to pull parts from, I'm guessing the front door module is likely shared with another vehicle (like a Palisade/Telluride) and the rear window regulator like is shared from a different vehicle. Tesla, however, has never built anything like the Cybertruck and therefore doesn't really have anything similar to pull parts from. There are pros and cons to both approaches. Also, in terms of material costs and Kia's choice to use less expensive but heavier materials for the doors, remember that the EV9 price tops out where the Rivian _starts_ . Yes, you can buy an EV9 that costs as much as an entry level Rivian R1S, but you can also buy an EV9 for $15-20k less than that. Material choices for things like body panels are largely dictated by the least expensive trim level.
