Jaz, thank you for this. I learned something very important. The display stand for the E-GMP is similar to others, but the E-GMP platform is not a "skateboard" as I and probably many others had thought. Specifically, the front and rear suspension and power trains are not connected directly to the central battery pack. That is a Very Good Thing.
Tesla has been making a big deal about their "structural battery pack" lately, which will eventually be attached to very large single castings front and rear to support the motors and suspension - essentially a "skateboard" to which everything else is attached. It offers some advantages, but the problem is that aluminum die castings do not lend themselves well to repair. So if you have a minor fender-bender that crumples one of those castings, does the car become a total loss (cost of repair exceeds used value)?
Tesla is also making a big deal of their new 4680 battery cells that will be used in a battery pack that will be essentially epoxied together, so not at all serviceable. That's a problem, proven by a Model 3 owner who hit some debris on the road, which cracked a plastic coolant pipe (which should have been protected!!). And since Tesla doesn't service battery packs, they were going to charge him $16000 for a new pack to fix a problem that their negligent design allowed to happen. He got it fixed for $700 by a shop that spent most of that in time researching a proper approach, but the actual fix was to graft a brass fitting to the plastic stub. It works fine, but Tesla is grumbling, and it remains to be seen if they will ban him from using Superchargers for his "unauthorized repair".
Why go on about this? Because the Ioniq 5 battery pack is easily removable from the chassis, which appears to get substantial stiffness from the pack, so it's "structural" like the Tesla. The 5 chassis looks to be able to support itself without the pack, so no special handling required. And the top and bottom covers of the pack are bolted in place, so serviceability is not a problem.
Hyundai will likely not want anyone but them to do any service work on the pack, but the fact that it is serviceable means the aftermarket can service it. If there is a weak cell, or a bad BMS board, or a coolant leak, the pack can be opened and the problem fixed. Tesla won't let you do that. Going forward, it may not even be possible for anyone to do that on a Tesla.
No one with an old ICEV replaces a tired engine with a brand new one from the factory. They have it rebuilt, or replaced with a rebuilt or used one. The same should apply to EVs and battery packs, and having a serviceable pack ensures that option will be available when the time comes. Even if the original owner wouldn't bother, the fact that it can be done means the car still has substantial value. That does not apply to Tesla.
I had been torn between a Model Y and a 5, but that video has me leaning much more toward the 5 now. My mind is still open though. We'll see what happens when info gets out about the new Y from the Austin, TX factory.
