Mach-E Brake Pressure Data for Each Drive Mode

[BMT1071]

I think generally speaking any slight variations in the different modes are outweighed by the differences in operator driving styles. I use 2PD exclusively and routinely consume 50% S.O.C. for each 150 miles driven so that pretty much means I average around 300 miles of range for an AWD EX. I think there are many others that use 1PD exclusively and have similar numbers.

I think Ford did a pretty good job with the various driving modes. They are slightly different from each other but still remain inside the boundaries of operation that Ford has predetermined for this vehicle. Except for the odd examples in Norway or wherever that big hill is located......it's pretty hard to be reckless with regen on this vehicle. Other EVs flirt with those boundaries a bit more it seems.

I agree. I have no interest in 1PD. If it were significantly more efficient I might give it a try though.

Been reading thread maybe missed it but my question is in 2pd is there regen going on during coasting like downhill

Yes, in "normal" 2 pedal mode you still get regen when coasting, it just isn't as aggressive as when in 1PD mode, and it won't come to a complete stop from that "engine braking". When you press the brake pedal it will start to regen first, and then apply friction brakes if you are trying to slow down at more than 90kW or so of regen, or 0.2gs of deceleration.

I did a quick drive last night in 2PD mode and it doesn't look like it uses friction brakes any more than 1PD mode, with the possible exception of very low speeds, like <5mph.

Thanks for the explanation Sam. I’m more a 2 pedal driver that will coast when I can but now w/ ev I wasn’t sure if it would help w/ efficiency or would 1 pedal drive be better and give me more (highway)miles b/c my Mach e has SR battery. I want to do a 180 mile round trip on a single charge from home.

From what I can tell, the efficiency won't be much different between the modes. Just drive gently, don't go faster than you have to (except when showing off to friends!), slow down gradually (except when you need to!) and you'll get the best mileage possible.

1PD is a preference thing, but I've always liked vehicles with strong engine braking, and I learned to drive with a downshift to slow, so 1PD feels very natural to me. I'd recommend trying it, but just because you might actually like it.

I drove 1 pedal yesterday,& have done a little in the past but paid more attention to change in style of drive. Things I liked that it.seems to have quicker launch from stop,,don’t have to move rt foot to brake,feather excelorator /coast to stop. Probably won’t be my primary mode but will continue to use thanks again.

I use 1PD to get ready for the racing pads I'll be using with my new wheel/tire combo. Racing pads use up disks fast, so 1PD will minimize the wear.

Did about 60 miles of 1 pedal drive on Sunday on my way home from Carpentaria Ca & can see how it could be applied to racing or dodging in & out of LA traffic w/o using the brakes

Not much, just drive the car. Many people have asked about whether 1PD is more efficient than other modes, or how often the car blends friction brakes with regeneration braking, and this attempts to answer that question, that in 1PD mode, without firmly pressing the brake pedal, the car will not use the friction brakes until after you are at a complete stop. This is basically "good news" because it means the car is doing a good job of regenerating energy, and not wasting much energy to friction.

Thanks for this insight . . . I am A bit unclear, however, if these insights also apply to a RWD car . . . as I await my Premium RWD, ER!

We don't know which motor is doing the regen on the Mach-e. For example, the Tesla does all of its regen from the rear motor, even if it has a front motor.

Logically it makes more sense to have the rear motor do all of the regen. Every MME has a rear motor. Then there's only one regen strategy to develop and code for.

So maybe they didn’t need the big rotors on the front wheels?

Makes sense

Regen braking isn't enough alone for all situations. Those big brakes is one of the features I like about the GTPE. Shortens the stopping distance on a 5000 lbs car and that's not a bad thing.

I don’t have a RWD to test, but given that they have favorable efficiency numbers then I strongly suspect that it relies a lot on regen as well, though naturally it can’t hit quite the same regen powers as the AWD.

We do know - check out my other posts with extensive data logs from various drives. The AWD uses the front motor for most of the regen (75%+), though it regenerates with both. A possible difference from the tesla is that the tesla uses an induction front motor, while the MachE has permanent magnet motors front and rear, so the regen efficiency is going to be good on both motors. On the AWD ER, the max regen power is about 100kW.

Logically it makes more sense to have the rear motor do all of the regen. Every MME has a rear motor. Then there's only one regen strategy to develop and code for.

Well, Ford does use the front motor as the primary regen motor on the AWD models - that makes sense to me because it puts most of the braking power on the front wheels where you usually want it to be. The RWD requires a different strategy of course, but I’m glad they kept the front regen on the AWD for the improved handling.
