According to
@wk057, an uncorked 60/75D can achieve near P85D Insane mode acceleration times. Tesla seems to be doing us bogus at the moment because apparently, their inventory cars built before July are being uncorked. Yet their personnel are telling us that only cars built July and after this year are eligible.
From what I can gather, cars built
after July are
already "uncorked" and
some cars built before July are fully
eligible to be "uncorked". So I guess they're technically not lying on this one.
I plan on testing some theories once I have time and cars available to test on, but from the info I gathered an uncorked 90D/100D has the same or better peak power output as an Insane P85D, with a 75D being not too far behind (~10% or so). The initial launch torque can't be the same, since physics shifts weight to the rear in a launch and the rear motor doesn't have the same torque as a larger motor. The torque ramp has to be a hair slower on the dual small motor cars for this reason. But from a 20 MPH roll I'm pretty sure an uncorked 90D/100D would smoke a non-ludicrous P85D. Should also totally smoke an original RWD P85 from a launch. (Pretty sure I still have the
only RWD Tesla that could hold its own at this point... lol)
I'm reasonably certain (upper 90% range) that there have
not actually been any changes to the drive unit or inverter itself to facilitate this. I know for certain that the small rear drive units are capable of at least 650A input... so two is ~1300A, or the same as a non-L P85D. A bit of educated speculation at this point, but what I suspect is that all 90D/100D's can be uncorked on the hardware/technical side of things (but Tesla isn't making that a big public thing). As for the 75s, my speculation is that they've returned to using a cell chemistry closer to that of the original 85s, as the 90/75 cells do not hold up on the longevity side as well as the 85-type chemistry. The 100-type seems to not be the same as the 75/90 and is holding up significantly better. So, my guess is that newer packs have the 100-type cells, and Tesla is now comfortable with taxing these more than the original 75/90 type cells in the smaller pack versions. Again, speculation... but I'd be very very surprised if I were wrong on this.
All of that said, I'm pretty sure *every* 60D/70D/75D/90D/100D can be "uncorked" on the technical side of things using
only software, but it may have some pack longevity ramifications for pre-July packs which is why Tesla won't do it. I'm also pretty certain that 85D's could technically be upgraded as well, but some packs would require a hardware retrofit similar to the P85D Ludicrous retrofit. I expect Tesla to do none of these things. They've zero incentive to offer enhanced performance on cars already sold.
