Some MS 75D have 0-60 @ 4.2 and Other 75D at 5.2

Why is it that most 75D on Tesla.com Used Inventory section have the slower drivetrain but a few cars have the update that was released sometimes in 2017. Slower models have 0-60 at 5.2 secs and faster models have 0-60 at 4.2 secs.

Why isn't Tesla selling all 75D with the upgrade? It seems they are doing disservice to customers who don't know the difference.
It seems both submodels have FSD. So how can one tell the difference other than their published 0-60 times?
It seems the range is also the same.

BTW, does FSD mean the car has AP 3.0 or did they have FSD with AP 2.5 as well?

If you buy a corked 75D, just take it to the service center and ask them to uncork it. And if it has FSD with AP2.5, take it to the service center and request the AP3.0 upgrade.

The caveat being not all 75Ds CAN be uncorked, so this is a bit of a gamble.

Is there a way to know which of the 75D can be uncorked? Are these cars made after a specific date?

There’s no super good list or hard cutoff that I’m aware of, but later cars are much more likely to be eligible. Has to do with the pyro fuse in the battery - “uncorkable” cars have an updated part that enables the higher current.
