Re: Anyone else out there constantly shifting between modes

Fri Jul 14, 2017 8:45 am

I use B as a downshift and travel at a distance were I rarely press the brake. I usually slow to about the last 15 feet and then apply the brakes if I need to stop or the person in front has a greater stop distance than normal or anticipated stop (greater than .5 car length from the car in front of them.

I use to drive the Leaf exclusively in B mode just for the predictable regen (slow down) feel. If I thought I would be able to coast a little more I go back to D or on freeway but for street stop and go traffic I prefer B. Just like shifting in my old manuals.

I am still new with mine and for traffic I keep it in ECO when it picks up I turn back to D to do 65ish.

I used to drive almost exclusively in B mode. But then I realized the most efficient use of momentum was letting it do its thing. Too much loss in the conversion back and forth. So now I'm actively shifting back and forth between B and D as I change areas I'm driving in. I almost never use Eco because, quite frankly, the lack of responsiveness takes most of the fun out of it for me. And the responsiveness is what I love most about the electric motor.

Now my mothers '13SL has separate buttons, one for ECO that remembers even after power down and the B mode which like my '12 you have to double shift every time to turn back on.


I'm wondering, for a 2011, is there any way to make ECO mode "stick" and be either the default mode when turned on, or even the only mode possible?

I'm a manual transmission type of guy who even loves driving old cars with crash-boxes that need double clutching to change gears.

I'm a terrible automatic car driver, always wanting to get the transmission to shift when I want it to, not when the car wants to. Mainly I like to engine brake. As such, even driving over several mountain passes I've never needed to change my brake pads on any vehicle I've ever owned.

As such, I also shift all the time in our Leaf, from drive to ECO to B to neutral. Sometimes I'm trying to hypermile, other times just trying to regen and save the brakes. For an example, I'll start slowing down in neutral. As I get close to where I need to turn or stop I take off ECO and shift into drive. Then as I get closer I turn on ECO again. And when I'm really close I shift into B. If I'm going down a long hill I've been trying a bunch of things. One, I turn on the cruise control and B mode and let the car just keep it's speed while bumping the Accel or Decel switch for corners. Or I switch between neutral, drive, ECO and B mode to maintain the speed I desire and for slowing down for corners. I've also tried shifting to B mode and using my foot to control the speed. Other than that I just keep it in ECO for accelerating and cruising. This is the fastest car I've ever owned and ECO just feels right.

However, I'm trying to give up on hypermiling so much, with the exception of when I need range. First of all I need there to be a level of comfort for the passengers, so I now just set the climate control to 70*F and turn on "Auto" and also drive about as normal as I can. Also, I find that when hypermiling I tend to not drive as safely.

On commute days, although I have a good buffer for my drive, I still try to get the most out of my drive as far as economy and range, so mode changing is rampant. But even on days where I know I have plenty of battery, I still use ECO and 'B' for slowing down since it's more beneficial for preserving the brakes and providing a bit of regen.

Driving around all the time in B isn't a situation I find myself in a lot since it acts like an anchor dragging behind the car and reduces the coasting in D which would be more economical in many situations.

My wife was in the car with me the other day and asked why I was shifting so much. I simply hadn't noticed the habit before so I was curious if others had adapted this driving style as well. I commuted with a manual transmission ICE for a LONG time, so I suppose it's not too foreign to me to shift constantly.


I switch between B and Neutral. D mode only by accident.

You can't keep up with traffic in ECO? I get the same max kw on full pedal in normal as I do in ECO. The mapping is just non linear in ECO, less on 0-50% pedal and it catches up near the end. I like a smooth acceleration progress. I'm not a hard gas, hard brakes, rinse and repeat that most US drivers do.

I can understand though that you don't need as much pedal movement in normal compared to ECO but the max power is the same so full pedal seems to match for me, maybe I'm wrong?


No, you're correct about the power availability. It's a common misconception that Eco mode "reduces the performance", but as you say, it's really just re-mapping the pedal-response curve. Both modes give you the full 0 to 100% range. Though I think it's ECO that is actually the linear mapping. I.e., advance the pedal 20% and you get 20% torque. 40% and you get 40% torque and so on. With Normal mode, the car behaves like so many others, over-weighting the initial pedal response. Initial 20% pedal movement giving you much more than 20% of torque. Personally I find the linear mapping of ECO to allow more precise control. I like having power when I want it, and not jerking my passengers around when I don't. The "economy" aspect relies on the driver being fooled into the impression that less power is available, and accepting slower acceleration as a consequence of the setting, instead of simply moving their foot to get the desired torque level.

So I usually use ECO, for the better pedal-response curve. The only drawback is it also de-rates the HVAC so if it's really hot or really cold I have to go to Normal mode to get proper heat or cooling. I wish these functions were separated, and the driver allowed to select HVAC power levels like almost all cars USED to do. A knob or slider controlling the intensity of heat or cool. Too simple, I guess.

B mode I'm almost always in, unless I'm "hypermiling", which happens maybe once a year or less. Again, it's about controllability for me. I love the idea of 1-pedal driving and looking forward to seeing how the new implementation works.

Well Eco does reduce performance of the climate controls but I have to say my A/C works excessively well despite the reduced performance. I love the fact cool air is practically instantaneous. Especially recently when I am in and out of my car several times a day and its always sitting in an open parking lot baking away!

Oh, it does work well. It certainly helps to not have the condenser sandwiched with a boiling-hot radiator :)

But on really hot days, getting into a 100F+ sun-baked car, I rather have the AC working at max capacity to get the temps down. Sure, you can pre-cool with CarWings but that's even more wasteful as you're fighting heat that can be disposed much more efficiently once you open the windows.

But agreed, the vast majority of the time, the output on ECO is fine for me. It's really only the triple-digit days where I'm looking for more. Or, if it's below freezing and I want a quick warm-up. Those days are even rarer here.

I've played with ECO mode on and off for the climate controls and never noticed any difference in comfort level or energy consumption. Then again it rarely reaches above the 80's around here. I'm not sure how ECO works with the heater. When it's -40* the Leaf's heater just barely keeps up either way, if it's sunny, midday, parked in one spot, no wind.
