Wear on motor(s) with 1-pedal driving?

[MME Farmer]

Just as an observation after watching this very interesting video. We use many 10 - 20 hp electric motors on the farm and about any of them appear to be bigger in size than these 280 hp motors. I realize that 400 volts vs 120 volts makes for a lot of the difference, but I only know enough about electricity to get into trouble so that's probably why it seems kind of amazing to me. I also noticed since my 21 GTPE does exactly 123 mph as it says it does and looking up the revs/mile on the extreme contacts I just put on, that means the motors are turning roughly 13425 rpm's so not far from their max.

That also means that when I'm out with my lovely bride enjoying this beautiful country those motors are still doing most of 7 grand.

Has a survey/study been done on the effect of one pedal driving on wear of the motor(s).

I never thought one pedal or two pedal affected the motors, but there’s definitely a difference. You can’t say they’re the same. one pedal when you let off it slows & stops and two pedal which I learned the hard way, cause I used one pedal all the time and kind of forgot the brake, got close to a car and let off the pedal and it kept going, coasting rather, so there is a difference in that situation.

For those that drive an EV, with 1PD and also drive an ICE vehicle, does it feel odd when you drive an ICE?

It does for a split second the first time you let off the gas and there’s no regen, but your brain switches modes pretty quickly and it feels normal after that.

Tesla might have done one since their cars have the longest history of that feature. Ask on a Tesla forum.

Actually, I had a plug-in hybrid Toyota that had this feature long before Tesla was an infant. Toyota's were and are extremely reliable. Tesla certainly has had many more cars with 1 pedal driving than anyone else by far.

Sorry, 240 volts not 120, what was I thinkin!

" won’t wear but there are bearing surfaces which can wear mechanically."

Of course. But that seems like a non-sequitur to me. If you are in 2pd mode, and you ease on the brakes, the MachE selects regen braking (turn on the “coach mode” and it will tell you how effective you were in getting energy … the closer to 100% the more regen and less physical brake action). If you are in 1pd mode … its the same thing. There may be some minor differences based on how hard you hit the brakes (a panic stop will definitely engage the physical brakes a lot ;>) .. but in my experience (based on the regen report from Ford) I think it is typically a very minor difference. But that may just be a reflection of my driving style, yours may vary.

Except that our car is always using blended braking.

If you speed up and slow down at the same rate, the effect on the motors and brakes are identical in every drive mode.

It’s been described as the difference between pushing a button or pulling a lever. The inputs are different but outputs are identical.
When coming to a stop, both modes use friction brakes below 4 mph as well.

I guess I should’ve said if I’m doing 65 and I let off the one pedal that thing slows down like right away when I’m in two pedal and I’m doing 65 and off it sure seems like I costed a lot faster. I guess that was all I was trying to say is it’s like a golf cart to me. It was instantaneous whenever I let off the pedal when I was like in excess of 50 miles an hour lower speed. I was just always hovering over the break in two pedal so I never really noticed it. It was the higher speed is what I noticed.
Or it could’ve been letting off at a lower speed heck I can’t remember anymore cause since I don’t have one anymore I can’t even remember so either way I felt more confident stopping with the one pedal than I did with two pedal. I’ll just say

I use one pedal mode... The thing you may not have tried yet is feathering your foot on the go pedal. The only time I'm going to "let off the one pedal" while at some significant speed is if there's a road obstacle that I'm just noticing, i.e. it's somewhat of an emergency, or I see that traffic is jammed up and slowed way down ahead of me.

In all normal driving situations, I very gradually lift off of the go pedal, including when I want to come to a complete stop for a stop sign or light.

As others stated, driving in this way in a Mach-E is exactly equivalent to two pedal driving in terms of motor and energy efficiency and wear and tear.

Even though I drive the EV more often, the EV is weird. No clutch pedal, no shifter. As far as engine braking goes, no. I know what to expect in each gear.

Depends on the drive mode you're in. I drive 2PD/Unbridled. It slows down pretty well if I just let off of the go pedal. When the car goes to Engage, it's definitely weird.

No, not at all. Zero issues when switching vehicles.

You have to feather the throttle to coast or slow down in 1pd. There’s rarely a reason to come completely off the accelerator pedal while moving. There’s also zero requirement that you or any one else like or use 1pd. I’ve never driven the car any mode other than 1pd.
