Porsche has the opinion that coasting is more energy efficient compared to recuperation.Having trouble understanding why range mode does not enable recuperation, or at the very least have it set to “auto”
If the whole point of range mode is to preserve battery, wouldn’t recuperation help in this endeavor?
Although I wish the recup setting would 'stick'. even though it isn't chosen recuperation occurs whenever the brake pedal is pressed (unless extremely hard). Notice how little brake dust is on your wheels. (note, if the battery is fully charged, recup can't occur until some of the battery is freed up for charging, no matter what the setting)Having trouble understanding why range mode does not enable recuperation, or at the very least have it set to “auto”

Coasting works better as the car relies on friction to slow down and can take quite some distance to do so thereby saving some juice. Recuperation would change that significantly.Having trouble understanding why range mode does not enable recuperation, or at the very least have it set to “auto”

Auto regen gives you kind of one pedal driving. It coast when there isn't a car in front, and regens when you get close to a car like in ACC.I've tried auto regen and I personally don't understand it. I have no idea what its going to do, under what situation, and how much regen I'm going to get. If I don't know what it's going to do 100% of the time, I don't want to use it cause I don't know if I'm going to rear end someone.
I learned to love auto. I find I have to use the brake pedal far less often in traffic but it doesn't lurch slower, which I feel when it's set to "on." It simulates how you'd coast or downshift with a manual if the car in front slows. Just don't overthink it.For efficiency and range, I would agree with Porsche that be avoid regen if you can. Whenever you transfer one form of energy to another, you will also have loss as nothing is 100% efficient. When you convert kinetic energy back into electrical stored energy, I'm there are losses due to mechanical, thermal, and probably some form of electrical.
One way that you can test this is to compare how far you travel by coasting down from 60 to a complete stop. Then you can compare this distance to how much you would travel with the battery energy you can recharging by stop the car with regen from 60.
I remember reading somewhere that regen can only recoup about 30% of the energy which sounds reasonable to me, but I haven't seen any true scientific numbers on this.
On Cruise Control & Range mode, they're kind two different things. One is dictating how the vehicle uses its energy and how to conserve that energy while the other is dictating at what speed the vehicle travel at regardless of everything else.

Not sure what it is about 'auto' that is not understandable.. It sort of works like 1/2 of radar cruise when your foot is off the accelerator. Nothing happens unless your foot is off the accelerator (like cruise does); at that point it monitors what is ahead and slows you down if you are gaining on the vehicle ahead too quickly, just like cruise. It is different because it won't speed you up if the car ahead moves out of the way, it will just end the slowdown and leave you coasting; you have to use the accelerator to speed up. Audi, which has a similar approach (surprise! but unlike Porsche your choice stays until changed) claims it is the most efficient mode because it prioritizes coasting as long as it is able and only applies regen if there is an obstruction looming. I learned to use it on an Etron and like it a lot.For efficiency and range, I would agree with Porsche that be avoid regen if you can.

I'll have to give that a try again and pay attention more when I get my Taycan back. I was assuming it be like 1-pedal driving which I've done plenty of in the Bolt.Not sure what it is about 'auto' that is not understandable..
