    When use the paddle to activate OPD do any of you notice the the car settles backwards a little bit?

    It drives me crazy. The leaf in e-pedal is so much better.

    Notice same thing occasionally. Seems to work best if you don't touch the brake pedal. I don't like that if you touch the brake pedal first before pulling the paddle then it doesn't work like it does if you pull the paddle before touching the brake pedal. In case it's not obvious, you are also able to pull the paddle while still pressing the accelerator to reduce the stopping power. This allows you to better control the exact stopping position of the car because paddle alone without accelerator tends to stop too early.

    Agree that one pedal mode is better designed on some other EVs. Don't like that you have to keep holding the paddle (or press brake pedal) every time you want to completely stop the car. Many other EVs will stop completely just by releasing the accelerator and never having to touch anything else.
  3. OPD means Optical Path Difference to me. A search in the pdf manual for this abbreviation comes up empty. Can you define it for me, please?

    I also do not like that I have to pull the paddle to come to a complete stop. I have also noticed that if I stop using the disc brakes, the car will resume rolling like an ICE automatic transmission powertrain that is idling. If I stop the vehicle using the paddle, it stays stopped until I tap the accelerator.

    Based on the title of the original post, I am guessing it stands for One Pedal Driving.

    The rollback drove me insane at first but I’m slowly getting used to it. Still sometimes I can see the look of panic in the eyes of the guy behind me.

    Turning on Auto-Hold will fix this.

  5. Is Auto Hold engaging the disk brake or the emergency brake? Also, what brake engages when auto hold is off when I have come to a stop using the regen paddle?

    I recently turned in my 2017 Bolt and leased a 2019 Kia Niro EV. The Niro has a much nicer interior but the one thing I loved about the Bolt was the ability to come to a complete stop with OPD. If you needed to add additional stopping power you could use the left paddle but 99% of the time it wasn't necessary. Why don't all EVs use this method? So much more convenient and, once stopped, it wouldn't creep. Great system.

    I have no experience with "true" one-pedal driving, so I'm left to really appreciate the Auto Regen in the Niro (and it's Korean siblings). I find it very good, and am happy to add just a little brake pedal at the end. Helps me feel needed! :D

    I'm fairly confident that if you experienced true OPD you would love it. Especially in stop-and-go traffic.

    Most popular EVs do (eGolf, BMW i3, Leaf, Tesla with recent software update). It's only the Koreans who lack true one pedal driving.

    The best work-around you have with the Niro is to keep holding the left paddle and using the accelerator to control where you stop. I wonder if you could just rubber-band the left paddle so it's always depressed (joking).

    Doesn't work, while holding the peddle no matter how hard you press on the accelerator the car just creeps along.

    Maybe if you could work up an actuator to squeeze the paddle when you let off the accelerator.

    All you need to do is get used to using the paddle and you can control exactly where you want the car to stop. You can hold it in and gauge where the car stops or you can pull it on and off to slow the car down with your foot either on or off the accelerator pedal. I rarely use the brake pedal and I can stop my car anywhere i want, 1 foot from the vehicle in front or 6 feet, etc. You need to turn auto-hold on and when you have your foot off the accelerator and pulling the paddle, the car will stop where you want it to and stay there, no creep. Is it like a Tesla that stops automatically, no. but if you wanted that you should have bought a Tesla. The Kia is really easy to get used to using the paddle and stopping where you want, just need a little practice.

    This has been my experience exactly. I came from a 2016 Volt (still own it, but my wife now drives it) which had no auto-hold, and the paddle on the Volt couldn't bring the car to a stop. In the Niro, with some practice, I rarely use the brake pedal at all as well.
  14. Even better than OPD in stop and go is Smart Cruise control. heaven. I had no idea how much mental effort Stop and Go takes until it took none.

    I was joking earlier in this thread but just for fun I actually tried tying down the left paddle and drove around like this for a few miles. It produced something resembling the one pedal modes on other EVs. You can drive around with the left paddle down even up to 60 mph or more and just slowly lifting foot off the accelerator to control stopping. Main problem with this solution is that regen is too aggressive with the left paddle permanently held down. It produces a very jerky ride since even slight movements of accelerator cause large changes in deceleration. Fun experiment but I'll stick to using the brake pedal.

    What I've found to be the best compromise for my driving style - I use level 1 regen 95% of the time. But when I come to stop lights that are not about to turn green, after I brake to a stop, I'll pull & hold the left regen paddle for a few seconds. Then, I can take my foot off the brake to simulate the "Auto Hold" at that light.

    I'm not a huge fan of Auto Hold though, because sometimes I prefer the creep, for example at stop signs (when in a queue). I have a few stop signs on my commute to work so Auto Hold isn't my favorite for that reason.

  17. SCC works great for creep situations. It does seem to be less energy efficient though if it is not stop and go.

    Not sure I am a fan of Auto Hold. Seems to take time to disengage the brake under certain situations.

    I'm looking at getting a Niro EV and ruled out the Bolt because it lacks Stop and Go. I test drove both a Prius and Kona Hybrid with the feature and instantly decided it was a must have feature. Until that moment I was considering a Bolt. I also ruled out Kona EV because only the Ultimate trim has Stop and Go. Niro EX has it and is way cheaper.

    This is an interesting thread. So many different ways to drive the same car.

    Having never driven a true one pedal driving car like the Leaf, I would have to say I don't fully understand how it knows when to stop? If the idea is that you just release the gas pedal sl-o-o-o-o-owly, that sounds like a lot of work to me. And there's always the re-programming problem. If I am coming up to a stoplight that is changing color, my instincts almost force me to let off the gas and move my foot to the brake. And stopping the car at just the right point by holding the gas pedal until it was in the full upright position seems like it would almost induce cramps, but I guess I'd have to try it to understand it better.

    As for the Niro, all those sensors and what-not, driving in Auto mode, regen level of 1, without braking at all, slows the car down in a proportional manner so that if the light turns green, I can just resume driving. As others have mentioned, you can use the left paddle to completely stop the car, so to me that's one pedal driving. I've not seen the roll back others mentioned when stopping with the left paddle (no auto-hold).

    True one peddle driving just makes it easier. There are times where the paddle isn't in a squeezable position when going into yielding turning lanes and just making turns in general. With use you get very good at knowing when to release to stop the car where you want it.
