What is the best regen mode of driving ?

[Petter]

Adaptive Cruise

I agree, really;-) May I ask why you seem to prefer Adaptive CC over Intelligent?

Unfortunately on the MME you really can't turn off OPD. Despite what is said everywhere. The level of regen varies but the car always regens a little bit no matter what you do. I have spent days trying to find a combination where the car does not regen with drive engaged but there doesn't seem to be one. Yeah I know on the efficiency mode the regen is barely there but for perps like me even that feather on the decelerator is too much.

The only true efficient mode is to switch the car into neutral. This is what I do, if there is a long downhill stretch coming. Most of my other EV's I can simply take my foot of accelerator and let the car roll. But not the MME. Its not to bad honestly, the knob is right there and a quick click gets you into neutral and rolling free. On one of my regular runs I can get 4.3 miles/kwh vs 3.9 miles/kwh without neutral.

IMO, the Mach E has more than enough range so I don't have to try and be a hyper-miler. It can just be driven. Use the mode that feels best to you.

Because I misspoke and said “adaptive” when I meant “intelligent.” My old brain struggles sometimes. I just fixed my post to account for the feeble brain cells!

Definitely Intelligent, and when BlueCruise drops, Ford will have my $600 in hand faster than inefficiently mashing the pedal to the floor at a stop light.

you can absolutely turn off OPD. OPD is not a synonym for regen.

and I guarantee your use of neutral is not getting you 10% more efficiency. Whisper mode has practically zero regen and regen is inherently pretty efficient so the notion it would make that big a difference is insane. The difference you’re noting is caused by difference in average speed or other driving habits/weather conditions etc.

On my car there is no regen in Whisper mode D (OPD turned off).
Does your car regen in Whisper mode?

We always drive in Whisper with OPD turned off. For me L is too agressive and I can't imagine driving with L selected most of the time. We have a local long, steep grade (Cuesta) that I was hoping L would allow me to maintain 72-75 mph going downhill without touching either pedal (like I can do in our RDX when in S instead of D). L slows the MME down to below 70. I judge how well I'm driving on the amount of time I spend without having my foot on either pedal. I feel this is one method to achieve maximum efficiency and smoothness.

I sometimes prefer Whisper in L. The cool thing about the MME is we have a bunch of choices to suite our own tastes.
When driving downhill in Whisper D and I lift off the pedal then my speed increases.

Yah! It does at almost all speeds there is very slight drag if I take the foot off. It is noticeable if you flip between neutral and drive. It harshes my ride to be honest. The smoothest ride is when The drive is not engaged at all, no matter the speed. I try to maximize my time in neutral. Just a different philosophy. To be honest I do the same on my Etron and my Volt. Both drive very similar in controls. The I3 is completely different.

I will have to connect my scanner and see if there is any regen in Whisper. Doesn't feel like it to me but the scanner will tell for certain. I have never tried Neutral. That might just disable the stator field which would be interesting.

Drive how you like, of course, but I think coasting in neutral is dumb and potentially unsafe, and without regen you are actually limiting your vehicle's overall range.

Confirmed. I read 0 kW in Whisper with foot off accelerator. (D mode OPD off of course). I moved the gear selector from D to N and back several times with zero difference between the two.

It makes no difference. Regen occurs automatically depending on the settings or by depressing the brake pedal.

As far as coasting in Neutral....normally I would agree but in my car Whisper mode is same as Neutral. Other cars might be different though......we have seen variances between cars.

I just tried it again. There is definite drag in mine. Anything above 30 mph noticeable esp if there is up down terrain changes. It may not be registering or getting back to battery but definite drag. Get to a decline get the car free wheeling down then switch between neutral and drive. See if that shows detectable drag.

EVs are not ICE and driving in neutral in EV is not dumb. There is no physical linkage between the wheel and chassis and all EVs technically will coast in 'neutral`. Been driving that way for 20+ years in EVs no issues.

 

[Frankie]

Coasting in neutral is absolutely dumb you're distracting yourself switching back and forth plus potentially reducing your ability to respond to road hazards for 0.1% increase in efficiency. If that. And efficiency that could be obtained by just feathering the throttle instead of switching to neutral. If the car didn't have whisper mode maybe it would be slightly worthwhile but the regen in whisper is so close to 0 you're doing this for what is nearly literally nothing.

Okay. Will try again at higher speeds and see if there is any difference. I was doing 30-40 mph when I tried it earlier today.
