Hello everyone,
I have a 2017 Leaf SL, and would like to know which traction motor do I have? Is it EM57 or EM61? Is there any difference between them?

Thx!

Dave
 
From some quick digging, seems like the '11 and '12 Leaf had the EM61 motor (e.g. https://techcrunch.com/2010/11/02/nissan-releases-final-specs-on-the-leaf/ and https://www.marklines.com/en/report_all/rep1049_201202).

AFAIK, EM57 was used from '13 to '17 and even '18 (e.g. https://www.autoblog.com/2012/11/20/2013-nissan-leaf-details-japan-more-range-better-charger/, lots of Google search results, and http://nissannews.com/en-US/nissan/usa/releases/overview-2018-nissan-leaf).

Presumably all of these are re: changes from EM61 to EM57:

Nevermind about this question. Found out with 2017 user manual that it is EM57. It is funny that 2010 ~ 2012 has EM61, and newer model has EM57. I would assume the newer the higher number it is.
 
I asked this question because it seems like the Nismo VCM is actually designed for 00 ~ 12 Leaf with EM61 motor. However, the general consensus is that the Nismo kit is for 13+, so this gets me really confused. The VCM clearly indicated ZE0 with EM61 motor.

Oh. I don't follow JDM mods.

Jeremy I believe made a typo at http://www.mynissanleaf.com/viewtopic.php?p=341832#p341832. The proper spelling should be Tim Gallagher. I met Tim at one of the places where he brought 2013 Leaf before they went on sale: https://wheels.blogs.nytimes.com/2013/01/13/nissan-gives-leaf-owners-a-preview-of-the-2013-model/ and http://sfbayleafs.org/past-events/2013/01/2013-leaf-bay-area-reveal/.
