Auto Regen?

[Jhenson29]

Yes of course, same on every EV I've ever owned. I guess you're not getting the one-pedal bit though.

ok. Whatever. I’m done. Thanks.

Coasting is good if you don't need to slow down. But in town/traffic you do so regen is required. My personal preference is to have a one pedal mode for that situation. That's all

It's a reasonable request to have a real 1-pedal mode as an option. I don't understand why Porsche keep ignoring this request. I personally don't like 1 pedal driving but making the option available via software seems like an easy win for Porsche owners who do like it.

Exactly ?

If I'm driving behind someone I use ACC with InnoDrive set to not obey speed limits (option to do so is asked each time), unlike Auto Regen it can slow the car to a stop.
Without anyone ahead I use Regen without Auto for an engine braking effect.
Like already mentioned, I would imaging one pedal driving to be fatiguing.

Having driven 1 pedal cars for over 5 years, I find them the opposite of fatiguing.

I think we've been there, and it's not as trivial as it may seem. (typed and deleted a long diatribe on technical merits.) You know what, it's a choice which, beyond technical arguments or restrictions, was based on a principle on the manufacturer's part, probably of philosophical nature (like, say, whether one sees cars as driverless taxis or as a driver's instrument). So while the request is, in itself, reasonable, I can't imagine why we would not accept that the unwillingness to honor that request is reasonable as well.

My problem with the "'let a hundred flowers bloom" argument is opportunity cost. I would rather have engineers working on other things. Yes, that's selfish and inconsiderate on my part, because it prioritizes things that I care about over things (like emulating Tesla's "one-pedal" system) that I would never use.

But I want to push back against the "there should be an option, even if you don't want to use it" argument, because I think it implicitly includes the flawed assumption that implementing the option would essentially be free.

There are people here that don't use the Range Mode, but it's still there for the ones that do.

One-pedal driving is not a Telsa system, it's an EV system.

It will be interesting to watch the evolution of Porsche's EV products over the coming years. Lets see if they add it eventually.

One-pedal driving is not a Telsa system, it's an EV system.

It’s not an “EV system”. It’s simply a decision on how to map the accelerator pedal to torque request. Onepedal driving could be implemented in an ICE vehicle if one wanted . ?

We're however literally talking about tweaking a few values of an existing function. They already have everything that would be needed for one pedal driving with the overrun recoup feature, except that the max regen is artificially limited to a too low amount. Even the brake lights will turn on if you somehow manage to slow down hard enough.

Literally, all that they would need to do is add another option to the recoup setting so that we have high, low, auto and off. An intern could do that on their lunch break (figuratively).

I'm firmly of the opinion that the only reason why they haven't added it is strictly philosophical. They're fine with spending I don't know how many man-hours on completely useless gimmicks like the photo library in the CarPlay app or the News app that no one has ever used or backseat displays that barely work. However, one pedal driving, which is something a lot of people have requested for as long as the Taycan has been a thing, is apparently an impossibility.

I’m not sure why you think that it “implicitly includes the flawed assumption”. I’ve worked in and around IT for over 2 decades and I understand the costs of developing and maintaining software very well. My argument is that this request is common in the EV world and I think Porsche should have it as an option on all of their EVs. Again, I personally wouldn’t use this feature. They can get rid of the terrible voice control feature at the same time.

Artificially limited? That implies there is a natural amount that’s being limited? What would that be? ?

I consider that a different argument from the one that I was addressing. I was referring more to comments along the lines of "I don’t see why they can’t just let us decide for ourselves how we want to drive" - I thought that did not consider the opportunity cost of implementing the feature.

Eh, typo. Of course I meant to write arbitrarily, as in there is no apparent technical reason why the max regen for overrun recoup couldn't be whatever value they wanted (within the capability of the car, obviously). I think it's pretty clear from the context what I meant. Being excessively pedantic helps no one.

Nevertheless, if you really want to know then yes, the natural amount in this case, would be to just let the car regen as much as it is capable of when letting go of the pedal, like most other EV's. The issue with the Taycan is that it's capable of a very high amount of regen, so even with a one pedal driving mode, one would probably want to have the max overrun recoup to be limited to some degree.

I don’t think it’s pedantic at all as many people seem to think regen is something natural for the electric motor to do. It is, however, part of the control, just as much as motoring torque is (with the exception that a PM motor is capable of passive braking; however the amount is still an engineering decision; and it’s not particularly applicable in an EV as it doesn’t use passive braking as the regen is actively controlled).

And no, I certainly didn’t know you meant “arbitrarily” which is a completely different word. And yet also incorrect if the engineers had a reason for its selection (as it is, then, by definition, not arbitrary).
