I guess this was the "power train upgrades" that were planned for the 4xe and the Gladiator in 2025 that I speculated was battery improvements.
Based on their current track record of being behind in EV tech adoption, the Gen4 was more likely to be the upgrade than the evo. That is what I and others said it was supposed to be. Regardless it would have been an amazing update. Battery improvements don't make too much sense as yet, as that one is a bit more justifiable for STLA to wait a couple years. If the Factorial batteries prove themselves, I would see that and other battery tech as the next battery generation for STLA.
Here is the speculation we now have, from most to least likely (in my mind):
1. Gen4 ZF Hybrid transmission kit
2. 2.0 Hurricane V2
3. Both of the above
4. Improved battery tech
5. 8HP evo
I think what we have is a classic example of "Perfection Paralysis" at STLA. They keep halting product that may not be perfect, or could be a solid stopgap, because a new feature/upgrade/evolution of a product comes out. So rather than iterate they wait for this new tech. That could actually explain quite a bit of the goings-on.
And when they finally release something, it is inevitably buggy, but not supported. UConnect 5 is a classic example that I will harp on. Much of it is a fantastic UX. But the stuttering sluggishness/bugginess is just plain awful. I am almost certain, given a month, the team I work with (or those of similar or better proficiency) could iron out the big ugly issues and send off a free CSN (Customer Satisfaction Notification), and improve perception across the board. For instance, there is no reason for the touch screen to be laggy by up to 30 seconds at first press. And there is absolutely no reason fixing this shouldn't have been a top priority.
