please focus on the main bottleneck, that is the actual battery.
I hope they put this in the Hyundai ioniq 6 first edition, as I have ordered one, and I would appreciate the extra range, they should do if they want this model to be a success.and get good reviews and feedback, here's hoping fingers crossed.
*charging* is the biggest bottleneck, rly. Miles-per-minute of charging. That requires motor+aero efficiency, plus weight optimization, plus actual faster charging.
So long as you can get that to a sufficient level, it renders "ultimate range" a bit of a moot point. Major energy density breakthroughs could make a big diff, but if charging is sufficient, they're gonna dial back pure capacity to save weight anyway (and $ on the batteries!)
