One pedal driving is always better than braking, but it doesn't mean you have to drive "choppy". Efficiency reduced by: driving faster (more wind resistance, more heat in the motor), accelerating quickly (more heat in the motor), braking (loss of energy due to friction), running accessories like heat. I am annoyed if I ever have to touch the brake when I am driving 1-pedal and I don't have an issue keeping my speed smooth (except when I am letting it rip!). Optimal efficiency case would be driving at a slow, constant speed. In an ICE, there is a trade-off in speed because you have different gears, but we don't have that issue in an EV.
If you can 2-pedal drive, but never touch the brake until you are < 5 mph, that would be something to see. Every time you touch the brake, you lose efficiency.

Where the Energy Goes: Electric Cars

EVs are 60% to 73% efficient, depending upon drive cycle (77% to 100% efficient if the energy recaptured from regenerative braking is counted).

As someone who has driven with regenerative brakes since 2005, one pedal driving offers only marginal improvements in efficiency.

That's good to know. I guess 1-pedal just sounded way more efficient .

My range has gone drastically down with the onset of moderately cold weather. This is really my second winter, so not surprised. I was more surprised last summer when I went out and my car had 332 as the range...

This is what the science-based reports say. I didn't like it.

That is not acceptable to me. I see your concern here, Bharjeej. I'm also getting around 230'sh miles on a full charge on my supposed extended range of 300 miles specified for the Mach-E California Route 1 and I'm charging here in California where it's not as freezing cold as in the mid west or east coast. I'm trying to find out about battery warranty claims and so far, the 2 ford dealers that serviced my Mach-E were not helpful. I'll be watching for more feedback on this post. Hopefully, we get good answers/advice.

Agree. Not acceptable. I have noticed that my Premium went from 330ish miles per charge to around what you quote.

it's about -10F here currently... I'm in Canada, and these temps are common until about March. What I've seen over the last few days is my range is cut in roughly half of what I was getting at peak in the summer (440km @ 100%, down to 214km @ 100% yesterday). In very cold, cut down in half is what I was expecting based the research I did before buying this thing. Car is outside all the time. So this is probably more of the extreme side of worst case scenario for range drop.

Please stop posting drivel like "what I was expecting based the research I did before buying this thing". And what is this "research" you speak of? You're probably one of those crazies that reads the manual on a $60,000 purchase too. My god man, get some reason in your thinking...

All I said was that the range drop of half is what I was expecting in this climate, I'm not complaining about it, I knew what I was getting myself into.... you don't pickup on the context of my post, and I'm the idiot?? I literally said "cut down in half is what I was expecting". No I didn't read the whole manual, but at least I know how to read!

I'm simply providing some feedback for people based on real world cold climate scenarios, not EPA ratings. I don't know how this is drivel, it's factual data.

I guess you missed the last line in my post, in brackets.

I disagree that one pedal is always (or even usually) optimum. Regeneration will never compensate for loss of momentum. Problem with one pedal is that, unless on cruise control, the velocity over time curve will tend to be more choppy with one pedal. Slightest foot off the accelerator, instant slow down -- yes, you can get some regeneration, but then you'll lose more than you gain accelerating back up to desired speed.

I personally have always used "low" as what I consider to be a nice compromise - have been doing this since I got a Chevy Volt in Oct 2015 and our MME in March 2021. With both cars, I get maxed regen by simply avoiding harsh braking, which engages friction brake. You'll actually get as much regen simply coasting to a stop while in the "drive" setting as you will with harsh deceleration in one pedal, plus, it's easier to maintain momentum, thereby avoiding need to accelerate to resume desired velocity.

But, as noted, my personal sweet spot is "low."

I'd suggest you practice more with one pedal. It's an amazingly smooth, responsive, and incredibly fun way to drive, especially on curvy roads. And in stop and go traffic, you can move the car forward and gently stop with virtually zero thought and effort (or fatigue). There is zero "choppiness" when done right...easing off the pedal properly allows for an exceptionally seamless transition between acceleration, "coasting," and braking (you do Not immediately go from acceleration to braking). You can transition between those three modes as slowly or quickly as you like - it's far smoother than having to take your foot off the pedal, move it, then begin pressing another pedal. There is far less (or none) "choppy" car response in this mode than two pedal. And I've been driving two pedal for 40 years.

An by definition, one pedal maximizes the regenerative power of the car. When you use two pedal, its impossible to know when you are in regenerative braking mode or friction braking mode (the car doesn't tell you when you've reached friction level force). I've tested both on my Mach E - I get at least 25% more regenerative miles in one pedal mode than two.

Don't take my word for it, here's an interesting article from the experts...

What Is One-Pedal Driving?

One-pedal driving in electric vehicles might feel strange at first, but it can be a lot of fun once you get used to it. Here's how it works.

IMHO, there are three reasons EVs are a blast to drive, and a superior driving experience to ICE: instant torque, low center of gravity, and one pedal driving.

As someone who has driven with regenerative brakes since 2005, one pedal driving offers only marginal improvements in efficiency.

It's more efficient in that by using the brake pedal, you have no indication when you are moving from regenerative braking to friction braking. So unless you are incredibly light on the brake pedal, there are times you're going to push a little too hard and move into friction braking (zero efficiency gain). One pedal is 100% regenerative. That's why more regenerative miles are gained in one pedal mode.

I agree, but I guess there is a Brake Coach setting that will tell you how much energy was regenerated during braking. Anyone have experience with it? I am a zero-brake guy, so I haven't tried it.

We use Engage all the time, and it's quite easy to feel when regenerative braking turns into actual friction braking, not difficult at all.

And no, 1PD is not more efficient. All the modes are the same - what changes is how YOU use them.

Can anyone confirm what's the mileage we get during this winter period. It is mentioned as 224 for Standard Battery version for a Premium model.
I am getting only 145 when i charge it to 90%. Please assist.

I just got my car (GT Performance) in December 2022. The mileage has ranged from 2.11 to 2.99 miles/kWh. For the first few months, I let the heated seats, steering wheel, and cabin air keep me a comfortable 72 F. In March, I have tried to keep those mostly off (but it is snowing today, so the heat goes back on). With no climate control on a 50 F day, the mileage goes up to around 2.99 miles/kWh. That will give me good enough range for my daily driving, but I won't be taking it on trips in the winter. Based on my data, my estimated range is about 260-270 miles around town with no climate control.
