Has this been established? I recall Nissan stating that the batteries were tested in Arizona prior to launch.
No, although I can't see how they could have done anything but brief overheat testing in Arizona and not discovered the degradation problem. I remember talk of them doing road testing in Japan. I also remember talk of Ghosn (sp?) overriding any TMS implementation in order to meet release date targets, so maybe at least some of the development engineers were worried about the heat tolerance. I'll make that first bit my opinion.
Nissan has an Arizona Testing Center. Not sure when it was established but https://www.motorauthority.com/news/102 ... test-track
allegedly from 2007 already mentions Arizona. https://www.nissanusa.com/about/corpora ... ation.html

NTCNA has a proving ground facility located on 3,050 acres in Stanfield, Arizona. Arizona's low desert terrain provides NTCNA with an ideal environment to test Nissan vehicles for hot weather, heat durability, engine cooling and air conditioner performance. The NTCNA proving ground also features a 5.7 mile high-speed oval and four individual road courses designed to test vehicle durability, reliability, and ride comfort.
allegedly from 2005 also mentions the Arizona Test Center at the bottom.
Before Leaf was launched, Nissan reps over and over, including Carlos Ghosn said the battery would be leased. So, perhaps they didn't care that much about long term degradation and needed to get to market by a certain time?
from Nov 2009 at ~26:55 talks about the leased battery. It seemed like it wasn't until the last minute that for the US, there was the about face about no more battery leasing. 1st Leaf went on sale in Dec 2010: https://www.engadget.com/2010/12/13/wor ... -the-futu/
. I'd imagine that Ghosn is pretty demanding boss. After all, he saved Nissan from near bankruptcy in ~1999, wiped out their debt, turned the company around and had Nissan making record profits.
and many other places) has a bunch of road tests starting at 7:00. The Paris video looks like it has Kadota-san in the driver's seat.
I was at Tokyo Motor Show 2009 (it's always around late Oct/early Nov of every other year now) and saw Leaf on display there. I still have pics. It's in https://www.youtube.com/watch?v=0rUCa2SA_Do
We may never know what the decision making process was, whether they decided to take a calculated risk (esp. in light of there being no capacity warranty at launch), whether someone didn't want to tell the boss the bad news, whether someone ignored news/data/advice, etc. After all, majority of Leaf sales are in Europe and certain parts of Asia (combined), where it doesn't get that hot...
