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.

 

I just test drove a model Y for the first time this week. They are telling me that deliveries for orders now are sometime in October and may be a 2022 model. They also told me that there have been two price increases lately solely to get people to buy the model 3 because many more people want the Y. I had heard a lot about the software but I was surprisingly disappointed and certainly felt like I was driving a dated car in terms of the tech functionality and lack of features and flexibility of the features. There has also been a number of changes lately including removing the radar which caused the feds to remove the safety certifications, in four areas I believe, since they currently have no way to test a car based on cameras only. BTW the cameras are far from perfect and often tell you to clean the camera/glass in front of it. A problem that would not happen with radar. At the moment I am still leaning towards the IONIQ 5 but am worried about what we will really get in terms of features in the US.

 

I hope Sandy Munro disassembles an IONIQ 5 like he’s doing with a Mach-E. And, while he didn’t disassemble an ID.4, he took a close look at its battery.

 

I completely agree. His comments on the VW MEB have made me give up on the Audi Q4. BTW VW announced that they are already replacing the MEB in 2026.

 

FYI, IONIQ 5 vs TESLA MODEL Y... :
Tesla great job, max speed, range especially leveraging its shape and weight. Still prefer, being in Europe, comfort. 99% of my trips are within 200kms one way. With the Hyundai IONIQ 5, I do look forward to ventilated seats, Android Auto, the roomy and comfortable interior, and HUD. Also like reclining seats with foot rest and reclining console for arms rest, all electronic aids especially against collisions, automated parking (Executive version), blind spot cams on dashboard when turning, V2L, sun shades integrated in back doors, electric sunroof shade, wide space available inside with good visibility through the back window etc. Also 5 year car warranty illimited kms (Max 80 000 for Tesla... Reliability issues?), and 8 year battery warranty (same as Tesla).

Comment by Park Shawn translating from Korean to English this video :

Ionic 5 LR and Model Y LR both have similar spec including weight, battery sizes. Details can be found on google. Here are some highlights from the conclusion they brought up at the end of the video. 1. Both car's AVG speed were about 100KM/h (Highway drive) 2. Both car's A/C and other convenience functions(like Highway drive assistance for Ionic 5, Auto Pilot for Model Y and etc.) were always on during the test. 3. 4 drivers drove about 100km per person and checked the remaining battery at designated location. 4. Both car have shown slightly poor battery performance than usual because of the weather condition (rain) 5. By just looking at the specification, Model Y can drive 141km more than Ionic 5. However the actual drive test have shown that the difference were only about 60~70km. This experiment have shown that IONIC 5's driving range is little longer than what Hyundai advertised. 6. They have concluded that both Ionic 5 and Model Y can drive from Seoul to Busan. The distance between those two cities are about 350km. Hope this helps.

 

You are right, I already explained it on the post Hyundai Ioniq 5 vs Tesla Model Y.
We need to give Tesla all the respect they deserved, because without Tesla there were maybe no EV's on the market.
On the other hand we must admit that Tesla still struggle in terms of quality. Hyundai did with the E-GMP platform a very big step forward compared to the competition. Knowing their quality, I am sure that is very hard for the others. About numbers Koreans are known to be correct, because they didn't admit any lie, it is a matter of honour. I see a lot of other brands promising super ranges that never can be reached. I saw a lot of videos where the IONIQ 5 started with a certain predicted range, nearly equal to their WLTP numbers and ending with a real range that was higher than the predicted one. Tesla has a lot of experience how to get the maximum range, but other will come closer and closer. I want to add that if the speed of charge is so quick, there is no need to have very high ranges, normally you stop every 200-250 km for a break and if you can add 100km in 5 minutes, the range is not so important anymore.

 

What could be the real world range at 225 000 kms ? At 300 000 kms ?
Price of a battery swap in 10 years?
Hyundai presents the IONIQ 5 as being built with a modular battery. See video :

Any hope in terms of maintenance and repair in 10 years time due to modularity?

 

As Apple are wont to say, batteries are consumable items. I presume battery replacement will become a niche industry at some point in the future. Hopefully within next 10 years before Ioniq 5 reaches end of battery life.

 

Thanks for sharing.

Thanks for posting this video. It is new to me. I really enjoy hearing about the engineering that has gone into the car.

I am no engineer, but in several videos I have watched of the car on a lift it appears that particularly in regards to the front and rear suspension the Ioniq 5 is very uncluttered and simple? The accident absorbing structure of the frame seems that way too. I think that the measure of an engineer’s ability is measured in terms of the simplicity of his solutions. So far all that I have learned about the car seems to indicate a very serious approach to simplification and improvements in efficiency. What are your impressions?

We are fortunate to have you on this forum. I value your opinions.
