Bake regen questions.

[RockwallRick]

I agree, whisper doesn’t feel the same as an ICE.

For me, engage feels the most like an ICE, it slightly regens and slows down like a regular automatic transmission car does.

Whisper feels like an ICE when you coast in neutral.

I’ll try to post a video soon I whisper showing the regen gauge to be sure.

I am going to do another “ hill “ test and this time I will switch over to L and see if this makes any difference?

I just took a video. It should answer all questions about modes and regen.

Whisper has none (unless you hit the brakes, 1 pedal or L mode).

I drive almost exclusively in whisper mode with 1PD. I have found going at full speed (70mph) and then coasting, and repeating this, while driving, gives me the best economy.

of course, roads and traffic aren’t designed for this kind of driving!

It's harder to see immediate gratification on regeneration in a car with as large of a battery as the Mach-E, but it definitely contributes. On my daughter's car, a Honda Accord Hybrid, you can watch regeneration alone charge the battery from almost empty to completely full going down the side of our small patch of the Blue Ridge mountains. It's only about a three minute drive down, but you'll recharge the battery completely from brake regeneration alone. The Mach-E is undoubtedly returning a good amount of energy too, but it's a smaller percentage of the overall battery, so it's harder to see the immediate effects. I can sometimes get the percentage to roll up one point if it had just rolled down, but it definitely adds back range.

I’d be surprised if any mode is automatically more efficient than the other. The only thing changing is how quickly it accelerates based on throttle input and how much the car uses the regen braking for you.

You can accomplish the same amount of acceleration and regen in any mode with your foot.

To be fair, the gauge is just a toy. Other than for the GT and GTPE that have power limited (so you need to see it), I’m not sure what practical application showing regen has.

If you’re slowing down, you are regenerating. It’s basically a “brake gauge.” And you know when you’re slowing down and by how much, no need to have a gauge tell you how much.

Agree. I don't really see any benefit with having a meter or gauge full time but it would be nice to have an option to show it on the main screen occasionally.

For example, we also have a Wrangler 4xe and it has "EV pages" on the infotainment screen and the kW is displayed for 3 items (engine, MGU1 + MGU2 and Climate. In 2H, the kW is limited to around 205 kW output but in 4WD the max of 280kW is available. Without the meter then we might not have figured out how to get sub 6 second sprint times. Similar issue with regen but of course to a lessor degree.

But yeah, having a gauge or meter full time isn't really necessary. The Wrangler has a full time gauge and I rarely even look at it. I think I would rather have the speedometer.

I guess we are never happy no matter what they give us.

Except whisper. At least on my GTPE, it’s a full coast, no regeneration.

IIRC someone tested this with an OBDII reader and software like ForScan. I think someone with this setup is needed to confirm.

Why? I posted a video on post #47.

Unless the gauge is lying, there is no regen in whisper when coasting.

I checked a variety of modes on my Premium AWD ER, and they all use regen before friction brakes. However, I didn’t look at the specific case of non-1PD, whisper, let off the accelerator but don’t press the brake pedal.

I’m not quite sure what true coasting would imply in this case, there is no way for the wheels to freewheel, so I’d probably define coasting as staying between -2kW and +2kW, something very close to zero current on the motor windings.

Not lying but that is a very small gauge and there may be regeneration going on that is below what appears in that small readout.

Nope, it’s pretty clear because the blue lightning bolt turns green during regen.
