Are you guessing, i.e. same motor or you do you have a source?
Cwerdna looked it up and posted it during our previous "discussion." The 2013+, 2018 and ePlus Leafs all use the EM57. I just verified it again.https://www.mynissanleaf.com/viewtopic.php?f=55&p=552295
Then it's very doubtful that Nissan would design a motor that would have a noticeable loss of efficiency at higher power outputs.
Most likely the motor was initially designed for future higher outputs, as is typically done in key design areas, but was limited
to lower power outputs via the motor controller (inverter/ECU/module/whatever) when used with lower capacity batteries.
Without any very actual/actuate efficiency logging data, what the repeatability of the efficiency tests were, and how Nissan
setup the different models for the EPA tests and Nissan's desired results
, one really is guessing as to the source of the apparent differences
