Not possible to turn off 1 pedal driving?

[bpwwer]

IMHO, OPD isn't good or bad, it's different.

Over the years, I have driven various EVs but only for fairly short periods of time. A short drive here and there. Long enough ago that I can't really member if they had OPD or not.

On my R2 demo drive, I played around with the various regen levels and did peddle off to see how each felt. Then after a couple of attempts at just slowing down normally, it was fine for the rest of the trip.

Of course I also have 6 cars and have to adapt my driving to each one as I may switch from car to car during a single day. The Boxster brake peddle needs a lot of force, but the 4Runner doesn't. After a couple of stops, my foot has calibrated its self to the car.

Some folks may not be as comfortable switching between the differences in how different vehicles drive. That's OK. They need to do what works for them.

I had only driven a Lucid for less than a half mile before for my first one-pedal driving experience. So this half hour demo was very interesting. I thought the lightest setting was too light. I almost ran a stop sign on the way out of the parking lot. Once I had it to maximum, that's where I kept it and now I wish my current hybrid did it. I don't ever want to have a car that doesn't have one-pedal driving.

I read that it’s not possible to turn off 1 pedal driving mode in the R2. Can anyone confirm this is true?

I absolutely cannot stand 1 pedal driving. I had a Nissan Ariya and it had an eStep mode I think it was called which is 1 pedal driving and it was horrible. When I let off the pedal it was the feeling of like instantly downshifting 3 gears in a gas car.

Why oh why would they not make this an option you can disable on the R2?

Because it's a prime "feature" of most EVs and relates to their claimed efficiency. At least with R1 there are 3 different settings for Regen....I'm assuming it's the same for R2 - but you still can't shut it off entirely.

not so, at least the way Porsche has implemented things, the brake pads are never touched unless it’s a panic braking situation. Coasting actually can gain more range then regen can recoup.

You do realize that Rivians can coast, right?

Look at the power meter next time you're on a flat, straight road. No power, no regen... You're coasting when your foot modulates the pedal accordingly. It's the sweet spot between not calling for deceleration or acceleration.

Coasting is simply allowing the momentum of the vehicle to carry forward.

Rivian does this in a way where you foot never leaves the pedal. Where you can easily maintain the same speed.

If you're going downhill and want to maintain a constant speed. It's better to capture that additional gravitational force into the battery pack instead of your brake pads.

Porsche is Porsche. Different breed of car. If you like their setup better, buy it. Rivian isn't changing anytime soon. More people love it than not.

I can't imagine driving without it. My Tesla has over 92k miles and is still on the original brakes.

I love 1 pedal driving. I test drove a Porsche Taycan and they simply don't use 1 pedal driving.

In fact, put a Taycan in gear and it will idle and move without you ever touching the go pedal.

Porsche went out of their way to make their EVs behave just like ICE car and thus I will never buy one

Letting fully off of the accelerator when using 1 pedal driving is like fully slamming on the brakes any time you need to brake at all. That's not how you do it.

You modulate the accelerator to control braking. This is something that takes a week or so to get used to, then it becomes second nature. No big deal.

Most car companies don't let you turn off regen because it causes a significant gain in range due to regen braking feeding to the battery. The EPA will penalize your range estimates if even the option of turning off regen fully is available.

It also causes your brakes to last the lifetime of the car and not need replacing. It's great.

Wish Rivian would allow you turn off regen. It would be more like driving a Porsche EV with the coasting and turning on regen if you want it.

You can coast in any EV by letting off the accelerator until the vehicle is coasting. That's it. It's that easy. I do it all the time on the highway.

? Well, yeah, but it immediately starts slowing to a halt eventually, unless you're in Roll/Coast mode... which apparently Rivian doesn't offer. That's the OP's point.

In the R1, lifting your foot off the go pedal is not like slamming on the brakes. It is more like a moderate slowing that is strong, but not unpleasant. In fact, I routinely slow using no pedal pressure when approaching stoplights or stop signs.

I try to let the truck bring me to a complete stop without touching either the brake pedal or go pedal. It's a fun game to see if I can time it correctly. Sometimes I do have to add a little to the go pedal, but if I time it perfectly, Iift my foot off the pedal and I never touch either pedal as it gracefully slows to a perfect top right before the line.

And it stops smoother than I can, so I always let it handle the final few feet.

And still, nobody has defined what “coasting” means and everyone is using it differently while saying the same thing and arguing.

If you let off the accelerator just enough that you're not sending power to the car, and you're also not activating regen, the car is then coasting like a Porsche EV or any gas car. Well, better than the gas car because there is usually some engine braking.

A lot of people don't understand this so I'll repeat: you can successfully, fully, 100% coast in any EV, no matter the regen setup, if you let off the accelerator to the point that it's neither accelerating or regeneratively braking. It's very easy to do by feel alone. In daily driving you probably do this all the time when matching speed with other cars on the highway and didn't even know it. I spend a lot of time coasting in traffic simply by where I end up putting the accelerator to maintain my speed relative to other cars.

The only way a person might never do this is if they let fully off the accelerator any time they need to reduce speed, even a little, which would be a strange thing to do.

I have successfully coasted with a 1-pedal system for 8 years in my 2018 Model 3, with regen set to full. It's very easy.

In my Model 3, I also play the no-pedal brake game at lights....but, the car has strong regen. I much prefer strong regen as you can then feather the accelerator to get the strength you need/want instead of always getting light regen and no more.

Nope, not at all, in a Tesla or Rivian with one pedal driving you cannot coast. The vehicle starts slowing down due the regen. When there's coasting, the vehicle can roll freely.

If you enable brake hold on the Taycan it will hold the car in place and not creep forward.
