I store my car from December to April 1st basically, maybe on "spring thaw" winter days I take it out. It would be a pain, but its not a totally unmanageable process to have to start it once in a while. I assume the app will show GTS owners what their battery level is so they can react as needed? However I do know some people who store their cars in commercial storage unit places, not at their homes. For them, this would be more of a pain to have to drive over to the storage unit to run the car for 30 minutes. But it is what it is, this is the future, the 994 will probably be all hybrid.

Lots of speculation without any official word, except the vague, generic , hybrid excerpt. So when the car is transported and sitting at port for months the car is DOA. I guess the sky really is falling.

official words are already out, the manual can be found on porsche website.

They even charge 12V batteries at the port. I've toured the BMW VDC in NJ several times - charging batteries is one of their common activities. The ports will need 400V charger units, like the dealer has (will have). And/Or, they will idle the cars to charge the 400V system, like the manual says to do. These cars move across the ocean and are delivered to dealers in time frames much shorter than 2 months. And they have to be driven off the boat, so they charge there.
Tell us how else the 400V system will keep its charge? Through a 12V charger and a step up? The car has a step up? And where are you going to get a 12V charger with enough amps to step to 400V and then charge that battery? If you read the long thread about this, you will see these discussions there.

I agree that there are a lot of unknowns at the moment for which I would also love some clarity. I think the idea of charging the high voltage battery from a 12V trickle charger is out of the question. There is no step-up transformer onboard the car that I'm aware of, and it would take a ridiculous amount of current to pull that off... far beyond what any trickle charger is capable of providing. What I will say is that lithium batteries lose charge very slowly, so if the car is parked with a nearly fully charged high voltage battery, I would guess it would last longer than 2 months. That 2 month estimate sounds like Porsche being overly cautious to me. I've left my Taycan parked for a month and it hasn't lost a single percentage point of charge. Keeping the 12V battery on a trickle charger does seem like a good idea, as the onboard electronics run off of that so there will be parasitic draw on the 12V battery. Getting to it to charge it is another story unless Porsche have wired in an access port somewhere.

At the risk of stating the obvious, it means to charge it until it gets back up to 80% or so. How long that takes depends on how discharged it was.

This is so crazy seeing how a lot of owners store the car for long periods. Can't believe they released such a car while knowing how their clientele are. This also ticks a point on why I personally feel it should be fully ICE or electric and not both.

I think everyone feels this way and hopes the owners manual is incorrect. But in the face of all the uncertainty surrounding the “T Hybrid”, the owner’s manual becomes even more authoritative. Will anyone drop $200k for this car until we achieve that “clarity”? Probably. Leasing maybe the way to go as ENCT suggestS. I hope someone buys them because the resulting RL threads on this forum will be very informative and on the leading edge of troubleshooting this new technology.
If you got the coin, go for it. If you have issues, just buy a climate controlled garage!
