    I don't care about the energy saved - I love one pedal driving. It's one of the best features of EVs..

    i went camping a few weeks ago. went up 2-3k feet in elevation. coming back down the mountain, I maintained 170m of range for 30 miles. it's really pretty amazing

      @@northerntesla yes i did. first time trying it. woke up to awesome rain drops on the roof that magnified vision. i could see the pine needles at the top of the tree canopy. returned to camping for first time in 20 years. came home and started buying camping stuff. going again next weekend. i'm lucky in that Albuquerque is so close to lots of mountains and national forests.

    I went through a canyon. It was a 20 mile canyon with major ups and downs.
    I came out having consumed 17 miles from the battery.. rather than a ICE vehicle having lost additional due to uphill work and mpg costs.
    I've gone down hill and seen my miles go up on my range.
    My work is 97 miles away. Consumed 82 miles Wednesday morning to get there due 70 mph and regen in morning traffic + going down that same canyon I mentioned.
    I don't know the exact number saved but it's dang effective.

    I don't understand the "lack of control" argument. I have a new Model 3 LR (my first EV) and descending mountain roads is pure joy. Don't need to touch the brakes, just modulate the accelerator like a dimmer switch; very smooth and intuitive.

    When you need to brake then regen braking is almost 100% more efficient than friction braking. It is a no brainer to use regen when you need to stop or slow down. However, when you are cruising down the highway especially when going slightly downhill the choice is between coasting and regen. In some specific scenarios coasting will actually be slightly more efficient than leaving regen enabled. You really have to enable and disable regen as you drive to maximize efficiency. Maintaining a constant speed the entire time is actually the single most effective thing you can do for efficiency when driving at highway speeds without traffic.

      Agreed. Although one thing to note is that regen is not just a binary it's engaged or not engaged thing. You can use the accelerator pedal to gradually control how much regen is used up to the max regen of the car. Say for example, you're on a straight road with a stop sign quite far ahead. In most cars like a Tesla, you wouldn't just abruptly come off the accelerator because the regen would slow you down too quickly, so you'd feather the accelerator pedal to only give you the amount of regen you needed. And in most careful driving, you'd only use the full regen of the car when you're at very low speed like the last 10 mph. Obviously, if you need to more suddenly brake then you'd either use the full regen or even press the brake pedal.

    Regen is "Full control of the car". Coasting is so much more dangerous than enabling one pedal driving.

      That's a huge leap to say it's dangerous.

      @@LearningFast I've been driving ice cars for 32yrs, and an EV with regen braking for about 6mo. I'm well aware of the differences. I would say one pedal driving is largely a convenience, and it might offer a fraction of a second difference. But it doesn't warrant calling ice cars "dangerous".
      If a fraction of a second of braking time is going to be a factor, you will definitely be needing your friction brakes anyway. So again, your argument is rather weak.

    • @LearningFast
      @LearningFast 3 месяца назад +1

      @@sonovabeach you’re wrong. That fraction of a second matters when stopping from highway speeds. At 70 mph you travel 102+ feet per second. Even a fraction of a second is more than 10 feet you lose of stopping distance.

    • @sonovabeach
      @sonovabeach 3 месяца назад

      @@LearningFast No I'm not. That little bit of time when your foot transitions from gas to brake pedal, your regen braking is not going to reduce your velocity by very much at all. Again, in that case your friction brakes are taking care of the vast majority of any measurable stopping distance. The number of instances where your regen braking is going to save you from a traffic collision is about nil. It's not designed for that anyway. Wasn't meant for that. Doesn't do that. So just stop.... get it? Stop. lol

    Curious to see efficiency between coasting down a medium hill to then return back up a hill vs regen braking down the hill and then accelerating up the next hill

      That's where the idea for the test came from, unfortunatley there's not an easy way to calculate energy consumption in such a small sample size. I do get the instant energy expenditure but would need some serious time and math to calculate it over a period of time.

    On motorways the regen is nothing, in towns and cities with stop start traffic, that's where it has good effect

    • @northerntesla
      @northerntesla  3 месяца назад

      Exactly, this is why highway driving is less efficient in an EV which is traditionally more efficient with ICE cars

    • @chaywarburton3488

      It's all about speed. Toyota will say you get 60mpg on a prius but they don't tell you how. You drive 80-85mph the whole way and see an average of 51. Why? Speed and those energy costs.
      Tesla will tell you. 70 or below. Use regen. This and that. I go 75. It always says "would have saved 5.1 miles this trip going below 70".
      Ice are not more effective. They just hold more gas. Comparred to a 2024 hybrid corolla, that's 48 mpg on a 11.8 gal tank, my battery is the equivalent same mpg but with a 6.8 gal tank. I just need to 'refil' more.
