I guess KIA/Hyundai has the better charge curve due to the fact they have more experience. They've had all those e-Niros and Ioniqs out there that they will have been grabbing data from via the app. At the moment Ford and VW are going to have to play it safe until they get more real world usage. The last thing they can afford is to be too generous and discovering a couple of years down the line that they need to replace thousands of batteries under warranty. Pre heating should bring the EV6 up to nearer the Tesla level if they do fit it- although the range lost by heating V's the charge speed is an interesting calculation. With charge costs hitting 40p+ in some places, I'm not sure I would want to blow say £2 in electricity for a saving of 4 minutes charging time. Actually I probably would!
Um, while I'm a Kia Soul fanboy... what you described is exactly what happened with the direct injection engine fiasco

As a buyer, I'm happy to put the risk onto Kia/Hyundai. I probably will only keep an EV6 for 2-3 years before upgrading. I won't need to worry about battery replacement lawsuits.... whereas as a current Mach-E owner... I am annoyed at being throttled.
Telsa has the best battery cooling system though. They use cylindrical cells and weave cooling plates throughout the pack so only 1/3rd of each individual cell is not touching a cooling plate. The pouch cells used by Mach-E, ID.4, EV6, Ioniq 5, Bolt - are less than ideal because cooling plates only touch a portion of the pouch so thermally the pouch could have large temperature variations.
The Bolt/Mach-E style cooling design by LG Chem:
Through extensive research and modeling, we dive into the Mach-E's battery issues. We also compare it to the Tesla Model Y and Volkswagen ID.4.
