Yes, that's correct. It's just quicker to use 'R' and you limit the regen when you need 'N'. It's instantaneous.

Rain actually has far more affect on range than temperature (within reason)... The last very heavy rain storm we had here, the temperature was about the same as it had been on the preceding dry days and I was not using CC, and still my range fell by about 35 percent. Enough that I had to find a 120 outlet at work to charge from or I would not have been able to make it home.

Actually, you will be able to increase your miles and m/kW h if you use "N" as much as possible instead of regen.
Have you actually tested and quantified this m/kWh increase, against simply leaving your LEAF in D or ECO?

I average close to 100 ft ascent/descent per mile driven, and generally just leave my LEAF in ECO, applying the pedal pressure to achieve as close to "neutral" power/regen, as is compatible with my desired speed.

Even when both battery capacity is over 90%, and when significantly altering your speed, to match potential energy available from the descent or the slowdown/stop, I seem to get extremely close to the same m/kWh results of shifting into and out of N, by just keeping my LEAF in ECO, and getting close to the same neutral energy application, when desired, using the accelerator/decelerator pedal.

So, the slight inconvenience and safety reduction of shifting in and out of N, vs the sleight benefit in m/kWh of doing so, has just not made using N while driving useful, In my experience.
no condition is permanent

Add me as a member: 110.3 miles over 1 charge. (low battery at 95, vlb at 109.7).

Took us almost a week to get there, but.... No highway driving but lots and lots of stupid red lights around Raleigh, NC.

Average energy economy on dash 5.5 mi/kw for this charge only. Average temperatures around 60 over the week (I'd guess) -- five bars of temperature on battery. (Anything else I need to report?)

Yeah, tell us how you get such a high energy economy number with "lots and lots of stupid red lights." By "stupid" I assume you mean the lights aren't synchronized. I can never even get it up to 4.0 when driving around town. Are you using Neutral to coast up to a red light? Feathering the accelerator in ECO or Drive? Heavy traffic or light?

Congratulations, by the way. I have never even come close.

Panet4ever:

You did not ask me, but I have 5.2m/kWH lifetime on my LEAF with almost all city driving stopping for lights every few blocks (or at best every mile or so). I have achieved 100+ miles per charge 12 times in the first 2,770 miles by avoiding jackrabbit starts, letting off on the accelerator as soon as I see a need to slow down ahead, and avoiding climate control on temperate days.

I suggest that you educate your acceleration foot by watching the energy consumption gauge on the dask or Carwings when you drive and trying to keep the meter above 6.

TonyWilliams wrote:The answer to your question is since regen is some number less than 100% efficient, you only want to use it when required (like an unplanned stop, or for those of us in hilly areas, when stopping on a downhill slope).

Otherwise, plan to let off the gas pedal as soon as possible and use N to roll to a stop.

Tony:

I tried your system today of shifting to N (by going into R with my teeth gritted) and coasting as soon as I saw a need to stop ahead. I have to say that it seems counter-intuitive to say that the last part of the coast (after applying the brakes) is better in N than in D or ECO. After awhile I starting going back into gear after applying the brakes to get some regen, which I did not seem to get in N. I am not a mathematician or an engineer, but is it really better to go all the way to a stop in N, or to shift back into gear by the time that you need to brake? What is the advantage to coasting the last part of the stop (after braking) in N rather than in gear?

Upon seeing a red light far in front of me, I coast (in N) as long as possible, then switch to D if more slowing is needed, then switch to ECO if even more is needed, then brake as the last resort. Much of the time I can "guess" to eliminate braking or even using ECO. However, I haven't quantified the results since I constantly use CC and don't ever need to drive more than about 20 miles in any one day, usually less than 10 mi. I've seen 6 mpkw for moderate periods of time so I know it's possible. Now that the weather has warmed up, maybe I'll give it a try.

One thing I did notice, there's no regen in N so if you have to suddenly brake while in N, you lose all that kinetic energy. :cry:

It's best to plan so perfectly that the car rolls to a stop without needing the brakes.

But, if you need the brakes, of course, don't do it in N !!!!

My 13th time to achieve more than 100 miles per charge at 107.3 miles 6.0 m/kWH carwings. Low bat at 96 miles; no VLB. That makes 1,437 miles out of the first 2,894 at more than 100 miles per charge (49.7% of driving, so I failed at acheiving 100+ miles per charge "most"of the time).
