Regen on vs off

[Coffinhunter]

Maybe I m missing something, but is there a reason to not have regen on all the time? What is the advantage of turning it off?

Not an expert but I think this article does a good job of describing it.

"So even though regen was better overall, the best way to squeeze the most range is to use a bit of both. Regen shines in stop-and-go traffic, and coasting is great on open roads. Instead of keeping your foot planted all the time, you can let go if road conditions allow the vehicle to cruise smoothly. "

Agreed.
That's exactly what I was told by a Porsche Techy as well.
Doing errands in town driving, regen on is better and on open roads turning it off.
This is what I do and notice it works better for driving as well as recuperation.

Thanks. Kind of what I figured. Since most of my driving is in town, with short bursts on the highway, I’ll keep it on.

I leave it on always and then for any highway driving turn on innodrive and let it handle.

Also, to clarify, unless the battery is almost full, using the brake pedal used blended braking, meaning regen happens for the first part of the braking action. The regen on/off that the Macan supports is just the regen on liftoff from the accelerator pedal.

i keep mine off. i think coasting is more efficient unless like others have said, you're in stop-n-go traffic where you not costing much at all...
I can coast for miles on the rolling hills of PA, using 0 energy...whereas if i kept regen on, i'd have to keep my foot on the gas for that whole distance

Regen is always on, no matter what when you hit the brake pedal and you're not braking hard. What you are toggling on and off is if regen activates when you lift the gas pedal or not. There's going to be very little difference as far as recaptured energy goes unless you're the type that goes full speed until the very end of a red light and slams on the brakes hard (there's always some who do that). If you drive like a normal person, it just comes down to preference if you want to coast or regen when you lift the gas pedal.

Personally I don't want my Macan to drive any different than my ICE so I prefer coasting, which is supposedly more efficient, but honestly we're probably talking about very small difference overall in how much energy you're saving.

Lol all these Porsche lingo is quite funny. Its the first time I have heard the term "sailing" which I gather is "coasting" I think dependent on your location:

Brake Recuperation = Brake Recuperation --> Regen via brake pedal
Overrun Recuperation = Thrust Recuperation --> Regen via releasing Acceleration Pedal
Sailing = Coasting

I still don't understand why Porsche doesn't offer full one-pedal driving, and then let the driver choose whether to use it or not...

Simply (as the Porsche representative answered me when I first got in touch with the car last august) because they are Porsche!
Coming from Tesla (and having loved the one pedal function) I missed it in the first week but then found out I can leave without it simply using the brake pedal.
The subject has been debated a long on this and other forum and there's no a unique opinion: someone love OPD and someone hate it. IMHO every brand has its own policy and design rules and it's hard to make them change unless something it's useful to all. Yes it could have been an "on/off" function on driver basis but Porsche simply think that you have to use brake (and in a sporty car I prefer to modulate brake as I love and not let the car doing for me but again IMHO).

About the regen ON/OFF debate I tested both modes one on my usual drive (150 km with mountain road and fast (130km/h) road) and found that for my driving style the coasting mode suites best to my consumption data (18,6 kW/100km after more that 18000 km). I prefer to slightly (or less slightly) press the brake pedal to reduce the speed than having a light (because the auto regen it's not the one you expected after driving a Tesla with one pedal drive function) regen always on. But it's my own experience.

It takes a a bit to get use to, but it feels nice once I get there. I like it On permanently.

After only 4 weeks of driving my new car, I now know why it is on the programmable button. And I don't intend to change it as I constantly use it on and off. Coasting is a great feeling when I have an open stretch, even in town. Then on when no open road and it does reduce the use of the brakes. And I agree, the amount of range extension or reduction is negligible. In essence, I use that button like I used "pedal" driving on my Cayenne.
