Car keeps moving in whisper mode

[ChrisO]

Try taking a video as evidence.

Unless you’re going downhill, it shouldn’t accelerate with your foot off the throttle in whisper and 2PD.

Sorry, I don't do "proof videos". I don't do videos at all. It was on flat, even slightly up road.

If you don't want to take my word for it, that is fine.

But maybe I will qualify it by saying "it felt like it was accelerating", I didn't actually look at the speedometer and see it going faster. The bottom line to me is that if you want your driving to feel like an ICE car you should be driving in Engage mode.

Normal behavior. I can coast 3/4 mile through my neighborhood. I start at 28 and get to my house at 23. Speed limit is 25. I like the coast.
A feature.

I personally wouldn't call that "coasting", not in the sense of like what an ICE car would do. Coasting is when power is no longer being delivered to the wheels. If I took a bike and got up to that speed and then stopped pedaling there isn't any way I would be able to go 3/4 of a mile and still be going at 23 miles per hour unless it was downhill. For a car to do so, it is not "coasting" it is still delivering power to the wheels.

The truth is that an automatic transmission car never coasts, but in my opinion, from what I felt with Whisper mode and two pedal driving, it is putting even more power to the wheels than a standard ICE car with automatic transmission.

I don't think this thread would exist if that wasn't the case. If someone used to an ICE car gets in an EV and tells you that it feels different, I think you can believe them. The question asked though "Is this normal". And for the Mach-E the answer certainly is: yes.

I know why I felt acceleration. I was almost stopped,. If you are stopped into pedal mode and lift off the brake the car will start moving, that's acceleration. Also on further testing if you switch between the two modes while driving you'll definitely find that you'll either slow down when going to one padal mode or speed up a little bit momentarily when going to one pedal mode.

All perfectly normal but in my opinion in whisper mode there's a little bit more power applied than in a standard ice car.

It is a very heavy car. Entropy. I like it as a feature. For your use case I would suggest you use engage.

No one said it coasts like an ICE would.

Whisper coasts when you let off the throttle. Similar to how it would in neutral.

What threw everyone off is when you said your car “accelerates.” FWIW, people have logged data in different modes and no power is going to the wheels in whisper off the throttle.

But yes, 2 pedal drive in engaged is the most ICE-like mode. That’s what I put the car in when someone new drives it who isn’t used to driving a BEV.

Thx to each of you. Re: coasting, this occurs at a complete stop. Which is not what occurs in either of the other modes. And never occurred until this week.

and I’m now either not using it, easiest solution. Or I’m employing auto hold now when I use whisper.
it’s just weird it started happening 2 months in, and never before.
thx for the inputs.

See your dealer. I just drove 15 mile round trip in city traffic for a blood draw in whisper mode. The vehicle slows as expected in one pedal drive giving a noticeable reduction in speed. Not as much at the other two modes but its there.

Try turning OFF and then ON one pedal driving, brake assist and other features. Like Windows 98 or your old Blackberry phone there are a ton of bugs and each software update adds to the rick of a setting getting changed unexpectedly... Dangerous in my opinion...

My car is a Select, early 2023, standard range, awd.

SPEAKING OF BLACKBERRY did you know that early SYNC software in Ford vehicles almost failed catastrophically until Blackberry stepped in and saved the day? Now you know...

THAT, was helpful! Thanks for the ideas. Was hoping to avoid the dealer, so I hope one of those works

Thanks for all the comments. IF this had happened on day one, I’d just rack it up to it behaving like an ICE. BUT, as I mentioned in the initial post, it only started to occur in the last week. I do use 2 pedal driving. And, in the other modes, when car is at a complete stop, it only accelerates once I step on the accelerator.
It’s not a big deal, just thought it was strange that it started just now to occur.
