I've been testing this on mine and I've found that coasting is far far more efficient than the recuperation mode, especially if you are also aware that you just need to touch the brakes when going downhill to get a bit of recup and slow down slightly, whilst still maintaining good progress

There is no reason why you can’t coast with one pedal driving as long as there is a suitable power/regen display on the dash and some decent software controlling the motor. I used to regularly coast in my i3 and rarely used the brake pedal. Make for a much better, if different, driving experience.

Got to put this theory into practice during a long road trip down to Spain last summer. Pretty much had zero margin for error due to a planned charging stop not working out, and coasting down the hilly landscape near Montpellier made all the difference. Reached the Ionity station with 2% of battery left!

But it isn't coasting. Coasting is just so effective on anything other than uphill. On the flat the car stays at the same speed for a long period of time, something it would never do with regen on

Great work and exactly! It's those very slight hills or flat sections where coasting really makes up the extra distance.

I've used 1-pedal an other cars and sure it works fine. But coasting really is brilliant in the Taycan, have been very impressed.

Don't know or really care about the efficiency, its certainly more enjoyable from a drivers point of view. Took me about 2 minutes after finally getting out of the 6 year nightmare of Tesla's to come to that conclusion.

I do agree absolutely, with my CT4/2022, , I couldn't barely go less than 30KWh/100Km, I decide to disable regeneration, and let the car cruising on free wheel, and wow, consumption drop to 25Kwh/100Km and even below, my range increase significantly from 360 to 410 Km @ 100% S.O.C, and we are in Winter still ! Never forget, lightly braking brings you back more recuperation than leave the car decelerating with recuperation ON.

You can be sure Porsche had enough data to decide the default mode.
It is true also in racing with efficiency formulae - which a lot of series have been on and off for 25 years plus - coasting at the end of the straight before braking gives the biggest reduction in consumption for the least loss of lap time.

Anyway I am pretty sure one pedal driving only became a “thing” because it is by far the easiest and cheapest way to achieve regeneration.
Blending it with the brake pedal is a major achievement.

Bravo to the marketeer who sold one pedal driving to customers as a desirable feature :)

The combination of the ability to coast combined with a low Cd is what would be called overpowered.

Yes, you CAN coast, but will have to both observe the power display all the time AND be very precise with the pedal foot. I don't think that is ideal, neither for attention nor for the best energy efficiency. The good thing with the Porsche coasting is that it is very easy to use.

I agree that one-pedal driving may be convenient: I don't have to move the foot to another pedal in normal driving. But when an exception comes where much braking is needed, I have to move the foot anyway. To me, the pluses of efficient and easy coasting and of having an active relation with the brake pedal is the best way.

Big fan of coasting compared to OPD/always-regen modes. Just easier to control the exact amount of input I want. There's also efficiency loss from the act of regen. Other factor here is tire wear as well. I would think the electric regen may create additional (at least slight) drag and wear on the tires?

They're right. Recuperation isn't 100% efficient. There are mechanical and electrical losses. Probably only 80% efficient if you're lucky.
