Porsche says One-Pedal is not the most effecient

[Socalsp3]

there's always that one guy that comes here about once a year claiming 1pedal is the greatest thing ever invented.

Because if the brake pads are wearing that means energy is being use to generate heat and not being put back in the battery.

And the same is true for 1PD as well.

I am exhausted ...calisthenics

Same.
BTW I think the MME brakes drag more than they should. I drive a LOT in 1pd and drive very damn well, lifting off well in advance rolling/coasting to a stop as best I can. BUT ALL 4 of my wheels are covered in brake dust. So to me the blended brakes of the MME kick in far faster than they should in order to make this incredible amount of brake dust in 200 miles. I've driven my MME almost 1000 miles. But cleaned the brake dust from the wheels 5 times. 5! times in 41 days of possible driving. I don't beat on the car, call it what it is HVJB-splosion fear. So it's not like the front brakes need to kick in for much but damn.

If your rotors are shiny, the caliper sliders may be getting sticky. Another ill effect of reduced brake use. If they are not, pads will shed dust more. I don't notice much dust myself. Living in the NE is hard on anything metallic, so I make it a habit to brake in neutral every time I drive. I also press hard on the brake pedal while stopped now and then to keep those calipers moving freely and to promote equal wear on the rear pads. Often the rear inner pads wear faster than the outers because normally braking rarely compresses the rear calipers enough to put much pressure on the outers.

Hold on here...the argument has devolved from one-pedal driving being less efficient than two-pedal driving simply because some people are not delicate enough with the brake pedal?

When I run the car in engage or whisper modes and apply the brake, it is much less aggressive than the resistance braking in unbridled mode. I don't stab at the brake if I don't need to. I trail brake even coming to a stop; I don't want that jolt when it stops, so I avoid that.

With that being said, if I begin to touch the brakes with zero accelerator input, does that not engage the motors regen until a specific threshold of the brake pedal is applied?

Yes, that is correct. Which is what we have been trying to explain to Norm.

Yes and no.

They’re all equal**

**unless the driver isn’t as smooth in whatever mode.

To your question in the last paragraph, yup, that’s how it works.

 

[Old_Norm]

Explain what? I never said that using the brake pedal did not cause regenerative braking. I merely said all things being equal 1PD would result in more energy going back to the battery than 2PD. I have no problem with people disagreeing with me but at least be factual.

There is always one guy who complains but adds nothing to the conversation.

Welp, I give up. I knew I should've hit the Ignore button several pages back

This isn’t the first thread on this subject. They always end up in mud up to the axles, and all for the same reasons.

Ok, let's clear some mud away. Everyone opposing my point of view has done so with opinions or anecdotes. Here is some real research for discussion.

It is a fact that you can press the brake pedal and no friction braking is used. You have provided zero facts to dispute that fact. And since that fact is the most important fact, I really don't understand why this is still a debate.

Calm down. Where did I ever say you could not press the brake pedal without engaging the brake pads. Making stuff up is no way to go through life son (apologies to Dean Wormer).

You've said 1PD is more efficient because it doesn't use friction braking. If you drive the same way with 2PD, no friction braking will be used either. Exactly the same efficiency will be achieved. Again, it seems like this should be obvious but you keep arguing about it and making absolutely no sense.

 

[Old_Norm]

So you admit that I never said you couldn't use the brake pedal without engaging the brake pads. Thank you. You said, "If you drive the same way with 2PD, no friction braking will be used either." So with 2PD how do you stop the car with no friction braking?
