I have over 3 years of (post-CW-update) Dash/CarWings data now.
As usual, I encourage all LEAF drivers to use actual range/recharge capacity data to find any errors in their cars reported (nominal
) kWh use reports, and any errors in the LBC reports of battery capacity, rather than trying to force the data to support either their LEAF's kWh use or LBC battery capacity reports.

This Summer my LEAF reported ~6.1 m/kWh nominal
That's ~30% efficiency increase since 2011.
Part of that increase is from driver efficiency (I more frequently drive low-speed routes, and more often drive relatively slowly on them) and part is probably from an increase in vehicle efficiency, but I believe is nearly certain that there has been a significant change in the common data my LEAF reports as a "kWh" on the dash, Nav screen, and from CarWings.
Each of these "kWh", whether from the top or bottom of the pack, range tests as the same constant unit of energy. And each "kWh" seems to have ~constant Wh capacity from one charge to the next, in the short term.
The question I have tried to answer from range/recharge capacity tests on MY LEAF is whether each of these "kWh", as reported in common on the dash/Nav screen m/kWh and CarWings has actually had a constant Wh content over the last 3+ years (almost
certainly not) or how much the Wh content per nominal
kWh has increased (the subject of other threads).
In any case, since I finally took my LEAF down to turtle for a long-range test, I can now report that my LEAF still retained more than 100 mile maximum range (~6.1 m/kWh x ~17 kWh x ~1.023 CW/Dash m/kWh odometer error = ~106 miles) in my average
driving conditions this Summer.
And I'm pretty happy about that.
126.1 miles to turtle (5 gids ), 17.0 kWh...
All miles above are as reported by odometer...
KWH use is as reported by dash M/kWh, nav screen M/kWh and Carwings, trip (ERS) and daily.
