Most Needed Software Upgrade for Dual-Motor 580 models.....
Powertrain and thermal management improvements
New powertrain management software allows for more liberal disengagement of the front motor in the Taycan's Normal and Range drive modes, which helps to reduce parasitic drag while cruising. Porsche tells us that it expects this tweak to contribute to an approximately 50-kilometer boost (about 31 miles) to the European WLTP range estimate for dual-motor configurations. The automaker does not yet have an estimate as to how this will translate to our EPA numbers here in the US.



That screen just shows how energy is being distributed. When it shows no energy being distributed to the front wheels, they are not disengaged and thus they are producing some parasitic drag.
What OP is asking for has already been done. It is not a “software update” because the motors are not capable doing such a thing. This will be standard for all EQ’s across the board for all 2024 models.
The better question is why wasn’t it done from the beginning? Lack of Disengagement and Heat pumps are two of the biggest engineering fails by MB… but we have the ugly “one bow design” and a windshield washer fluid port!

I've put approximately 1,000 miles on a 450+ loaner (1 long road trip) and over 6,500 miles on my 580. It is immediately evident in the 450+ that the car has significantly more range than the 580. Most likely culprit to me at least is the parasitic drag of 2 motors vs 1 with the same size battery pack in both cars.
