Missing recuperation option in vehicle settings

[redranger51]

I just picked up my 2025 RWD, coming from 10 years of 2 different Tesla Model S. I'm interested in the recuperation, since I've been used to the strong regenerative braking of the Tesla. I have the dashboard icon with the reverse arrow, and the steering wheel button is set to control recuperation. But there is no option for recuperation in the Drive settings, and pushing the steering wheel button does nothing. Can anyone help me with an explanation for the option being missing?

The way this function works and on the refresh 2025 model in particular is the following:

Porsche's heritage based stance is that coasting is more efficient than recouperation, so we get this expectation out of the way. This means that any form of recouperation will be very mild.

Recouperation not controlled by the driver is always on behind the scenes. You can see evidence of it when coasting down not so steep hill and seeing the green bar showing that the car is recouping or viewing the Trip graphic that shows when the car is in recoup mode.

Then you have Driver controlled settings that are:

Off - no additional to the above recouping is on
On - additional recoup is always on when you lift foot off pedal
Auto - this is designed to dynamically recoup when a car is in front in stop and go

The control of these settings are in the PCM as shown below under Drive:

And you can assign the Steering Wheel button to control it, but the button cannot be assigned to control all 3 settings Off/On/Auto at once, you can only I believe assign it to On/Off or Auto/Off.

Also, there is no more Individual mode, so Recoup setting can be saved under the Drive mode now as form of individualization of each Drive mode.

Recoup mode is shown on the main driver screen with an icon when it is On or Auto.

Well, I wouldn't put it quite that way. I would say "throttle lift-off recuperation will be very mild." Unlike the Model S, the Taycan has blended braking, and Tesla-level recuperation happens when you brake. The throttle lift-off recuperation modes are mainly to reduce fatigue when in stop-and-go traffic, not so much for filling the battery. Note you also can get strong recuperation when in CC or ACC going downhills to maintain speed.

What threw me off was that I was looking for the setting as in the picture above. Apparently with the latest software that's changed, and now the setting is in the lower right of the screen. Thanks for the replies!

I meant to attach a picture of the screen.....

I am using online simulator since I do not have a 2025. That is helpful what you are showing and looks similar to Macan EV.

Coasting being more efficient has nothing to do with Porsche’s heritage. It’s just physics.

It’s much higher than Tesla, unless Tesla has had a significant increase recently.

That’s very interesting. I’ve never seen a comparison and have always thought that it was much higher in the Tesla. Do you have a reference for that?

My point on heritage is that Porsche will not introduce one pedal driving although it can since Audi SUVs have regen modes, paddles, and B mode - whatever. Lots of owners coming from other brands keep complaining about why no one pedal, why no regen modes, and so on and the answer is simply heritage that is non-negotiable if you are driving a Porsche.

Taycan: 290kW (from 2023; not sure one refresh)

Tesla: 70-80kW

These are just some of the first hits I found. Feel free to search yourself and report back.

Well, I did look and the data in the article and video would contradict the idea that coasting is more efficient than regenerative braking. There are certainly more factors involved in efficiency than the braking system, and there probably isn't any way to tease out each one's influence and compare them across vehicles

You can’t compare the system as a whole to judge the utility of one component. Coasting is more efficient than regen. It’s not really open for debate, although you wouldn’t know that from the number of times it’s been “debated” on here.

The person in that video is a moron. Maybe a Rivian development engineer?

I’ve said it numerous times before. But I’ll say it again. For fun. Regen is not itself desirable. It is just preferred to friction brakes.

In older Taycans with dedicated button for recuperation, the same button allows Off/On/Auto (Auto is long press). Why would they remove this functionality in new, programmable button?

They have removed this functionality. I drove a 2025 and the programmable button DOES NOT support a 3 function On/Auto/Off that the fixed button available on J1.1 supported. Long press is not supported by the programmable button.
