Whisper vs unbridled rolling

[RosarioM]

Has anyone noticed that in unbridled mode the car breaks when you release the accelerator even if you don’t have one pedal driving or auto hold on? Much more so than in whisper mode? I even see the regen bar go up a lot more in unbridled. Is it some safety thing or is it forcing the regen to save on battery?

Unbridled has more aggressive acceleration, deceleration and steering.

I u defer and aggressive deceleration when I’m braking but should rolling be the same. Essentially like the car was in neutral? It feels like I have one pedal driving on.

Have you driven a powerful car with a manual transmission? When you let off the gas, there can be significant engine braking. I think that is the feeling they are going for.

Just because 1PD is off doesn’t mean the car will roll freely. Some regenerativere breaking is normal even without 1PD.

I actually prefer Unbridled with one pedal off. It is smoother than one pedal and eliminates most of the natural human reaction delay if you need to brake unexpectedly.

This is by design and has matched Ford’s description of the drive modes since the beginning.

That's just the way Ford decided to set the drive profiles.... Whisper has no regen slowing, Engaged partial, Unbridled a lot, 1PD max. And "L" gear sort of medium-high. With similar gradients for accelerator pedal mapping, and steering wheel tightness.

I do agree that it's a shame they don't let us set all those independently to a create user-defined drive profile though.

Personally I love Whisper for easier steering and more play in the accelerator pedal (to apply more finesses). But with "L" gear always on to get some regen slowing, while still keeping creep and the brake pedal for the final stopping on the low end. Perfect combination for how I prefer to drive. But I have to hit that L button every time I put it in gear. Be nice to define a custom drive mode for that instead.

Is the L mode the same as turning on auto hold in the settings or that’s something different?

They‘re different. L mode increases regen when not in 1PD. Auto-hold engages the brake to hold you in place when you come to a complete stop.

It sounds like you might benefit from a perusal of the owner’s manual.

Whisper is the mode I'm driving in now, exclusively for this reason. I've seen a fairly significant improvement in efficiency by allowing the car to coast.

No, very different things. In fact, you could almost call then opposites. Autohold is just when you're stopped. It means you don't have to keep holding the brake pedal down to remain stopped. It disables the creep effect of easing off of the brake pedal and creeping forward. It might just as well be called "CREEP OFF". (1PD mode has the same effect as it slows all the way to a stop using regan and then friction braking and holds you there with no brake pedal.)

"L" gear just applies medium regen slowing (when easing up on the accelerator pedal) while moving above 3 MPH. That's roughly the minimum speed where regen does anything. Further slowing/stopping below that requires friction brakes (either with the brake pedal, or automatically with 1PD mode).

Doesn't seem to me there should be much difference in efficiency with Whisper. Slight, but not much.

The brake pedal uses regen for gentle slowing too, just like Engaged and Unbridled do. Except for hard slowing (where friction brakes have to kick in), it should be the same amount of energy recovered from slowing either way because it's really using the same regen.

However, it does tend to change the way people drive. When we have an automatic regen mode on, we tend to be slowing more frequently. Which means we're slowing down and speeding up more frequently than just coasting through some of those stretches. And coasting is more efficient than more frequent up/down/up/down speed (since regen isn't quite 100% efficient).

There very much is in my driving. Coasting down a hill I can take my foot off and it keeps speed and if it starts to gain speed, regen kicks in to maintain coasting speed. With unbridled if I take my foot off the gas going down hill I still slow down so to keep speed I need to keep throttle JUST right. Too much effort and room for error in my own foot and as a result I don't have as high efficiency.

I'm talking seeing a difference of 2.2mi/kwh and 3mi/kwh on the same trip, same conditions, using whisper and trying real hard vs unbridled and trying real hard.

Yes.

You have different amounts of regen based on the mode. The GT also has a power gauge where you can see it.

I made a video showing the differences:
