The title of this post, Leaf 3.0, is misleading - this is the demise of the LEAF, not a new gen.
Also, I don't understand why people are speculating that the new crossover will be based on the LEAF platform as it states clearly in the news release:
The purely electric crossover model based on the Alliance platform CMF-EV announced by Nissan in the summer is to replace the Nissan Leaf from around 2025
This crossover will almost certainly be CCS, actively cooled, and with a larger pack. Nothing short of that would sell when almost every other competitor of note will offer all three of those things, not to mention 100 kW+ charging rates.
