Differences Found in Range Capacity When Using 1-pedal Drive vs. Not Using it

[Adventureboy]

I don't "get" how regen braking happens w/o the 1PD (I thought that the automatic braking IS the regenerative aspect, which doesn't happen w/o the 1PD), but I guess I accept that. I'll note that I prefer using 1PD, but, just as JohnFoxeSheet wrote in his marriage, my wife dislikes it too.

Regen happens in 2PD when you apply the brakes. The first part of the brakes are accomplished through regeneration and pressing harder applies the physical brakes. It is nearly seamless to the driver in 2PD; however if you pay close attention as you apply the brakes, you can feel the slight difference when the physical brakes kick in.

Interesting! Thanks, Adventureboy!

I have been experimenting with unselecting the 1-Pedal Drive button, and have found that the car feels faster. Of course this means I lose the feel and benefits of regenerative braking. My question: if I drive a significant distance w/o the regenerative braking on, will the car's range drop as a result? Has anyone tested for this?

The only reason it “feels faster” is because the car coasts . Seriously if you drove a manual transmission car around in 2nd gear it would feel similar but would not have the benefit of regen. Once you get used to 1P then turn it off the car feels like it’s running away.

(EDIT: If you are in Engage mode and have the Brake Coach on you can see it in action. If you can get it to 100% (by lightly braking) then you are basically getting the same regenerative breaking as using 1 Pedal and stopping with just lifting off of the accelerator.)

I would like to see the brake coach post efficiency when I am using adaptive cruise control or blue cruise with the ugly stopping function vs one pedal slow down to a stop.

I typically release adaptive cruise control when I know I'm coming to a stoplight to control the stop better.

100% true, I instantly felt like I was in a manual with transmission braking once I turned one pedal on and it became a no-brainer

I really like the 1PD because of the speed controllability. It is really quite easy to manage your speed with it once you get used to it. It works well on hills, curves, bumper-to-bumper traffic etc. After a few days with it, I never looked back. The trick is to develop the muscle memory for where the neutral position is on the accelerator. That's where the car coasts and doesn't apply power or do regen. Up from there applies regen, down from there applies power. This also keeps the driver behind you from getting frustrated with your brake lights flashing on/off as you hunt for the right spot....

Me too, I find it really strange that you only see it in Engage mode, not even in Whisper or Unbridled.
The closest explanation I can come up with is that Engage mode is the closest to how an ICE car feels and this the "teaching mode". But it would be really nice to see the same kind of information all the modes and in situations like what describe.

I've never tested this, but I can't imagine it would make a significant difference.
I consider 1PD the best option available on an EV, so it will remain on.

No, regen first occurs when you lift off the throttle.

Ditto this /\ /\ /\

118,250 miles in 51mths on OPD and never even once considered turning it off.

Never done a comparison between one & off.

Achieved an average of 2.9miles/kWh but that’s due to car virtually always loaded upto its max permissible weight with A/Con & heating set to 21deg C.

Regen does not occur in 2PD until you press the brake pedal. If you remove your feet from the pedals in 2PD, it will just coast. In 1PD, regen occurs when you lift off the throttle.

No!

Regen occurs the moment you go onto overrun when throttle is released, any mode, though some modes not as noticeable as others and on OPD!

Ok, now I'm curious. Perhaps they are configured differently in the UK? In 2pd on my NA 2022, there is no noticeable regen with the feet off the pedals. It just coasts. If you are pointed down a hill, it will pick up speed. It is the same as shifting to neutral. Both my MME and Lightning work that way in 2PD, so if there is any regen, it is negligible.
In your's, do you actually feel the regen drag in 2PD with no feet on the pedals?

I doubt MME’s are configured differently in this respect in UK, no noticeable regen is not no regen

The statement is absolutely true. On my MME in 2PD, regenerative braking is applied when you press the brake pedal. There is no regenerative braking when I release the throttle in 2PD. This is the difference between 1PD and 2PD.
