WNJ8 "Not Avaliable" for 2022 CT4?

[W1NGE]

Just got car back yesterday.

Was initially very excited to see that there was now a selection for "Auto" under "Recuperation"

unfortunately it goes away each time you start the car, so we are back to having to manually hitting the regen button every day

Auto recuperation has been in place since 2020. The recent updates simply keeps auto enabled when changing Drive Modes.

I believe settings like this are reset to default on power on to adhere to regulations rather than logic.

.......I believe settings like this are reset to default on power on to adhere to regulations rather than logic.

Cant be. Every other EV I've driven, including the little $27k Chevy Bolt has regen that will stay on after restarting the car. We all know this saves brake pads and puts a little more energy back in the battery. Why on earth not on the Taycan? Only two plausible explanations:

1. Helping dealers with more service revenue (changing brake pads more often)?

2. Somehow regen does not deliver a "Porsche driving experience"?

I dont know but I remain disappointed that the Taycan cant do this. A real shame given its position / price point in the EV market.

As a data point, my CT finished production in April 2022 and was delivered in June. I just received the WNK1 update.

OTA?

Here's another plausible explanation:
3. Government mileage/efficiency ratings are based on test driving with default vehicle settings. The Taycan's default coasting behavior, where regen normally only occurs when pressing the brake pedal, is more efficient than one-pedal-driving behavior, and therefore improves the government efficiency rating. The Taycan's seamlessly blended brake pedal regen is a technical achievement that some other EV carmakers have not been able to replicate, so they've resorted to one-pedal driving and friction-only braking.

OTA?

No, was performed at the dealer.

Dont really care what the default vehicle setting is. Just want the auto regen to stay non-defult once I have configured it as such. Do the government regs actually say that the setting has to revert back to default every time the car is turned off? Nobody else seems to be doing this (at least of the other EVs Ive driven).

Yes, at least with the US EPA testing, the mileage/efficiency calculation has to be made with the default settings of the car. One reason "nobody else seems to be doing this" is that until recently, nobody else had achieved the Taycan's quality of blended regenerative braking that makes it possible to have a "normal" driving experience where you can coast and brake, even hard braking, without using friction brakes. In other words, other EVs must use one-pedal driving to achieve regenerative braking efficiency because they are technically inferior to the Taycan.

Genau makes some good points. I was shocked to learn that Tesla brake pedal never does regen. I much prefer the Taycan style of regen, and the computer doing the work of blending regen with mechanical brakes.

I get the impression that a lot of folks are confused and think that Taycan only regens if the regen is selected to on or auto.

My 2020 received the WNJ8 update a few weeks ago.
2022 should be ANA6 - the dealer will know

Its the same uPdate, different campaigns depending on model year

And you get colorized icons after WNJ8 update right ? MY2022 CT4 scheduled for this update.

i wouldn't be so cynical.

Discs are used from initial start for 1/2 mile or so and so recuperation can't be available - logical therefore for 'Auto' to be disabled as it isn't active. Brake pads will likely last longer than you'll keep the car given 97% of braking is via the motors unless you do a lot of emergency braking!

Interesting comment from the UK PEC experience from one of the instructors I read this morning - upgrading brakes to either PSCB or PCCB is a cosmetic step given the lack of brake usage in daily driving (!) - so brake disc / pad wear is not a concern ever.

Porsche offers 'coasting' which actually is more efficient than auto or manual recuperation - in particular overrun recuperation (which is what you are referring to and not energy recuperation via braking which provides most recuperation). I'm sure they've thought this through.

The Taycan has objectively better efficiency with coasting and blended regen braking. This car never promised one pedal driving as the core experience.

In this regard, the ‘how dare they not let me configure and drive the car the way I want’ problem is solved by buying a different car that better suits one’s preferences.

My 2022 CT 4S is awaiting campaign WNJ8 and the dealer says the software is not available.

strange.
CT4, My2022 -- currently at the dealer upgrading to WNJ8.

If you check the press release the update is being rolled out by region so it will materialise.
