Also with regards to pricing, I'm guessing it will be +$6K USD or so more than 40kWh Leaf, to play at the <200 mile range club. Especially since it will have ATM (Active Thermal Management) and more goodies.
I'm guessing as well might be different battery chemistry again, maybe moving to more Magnesium with Artificial Layers to improve Ion flow on the Anodes. Also maybe some improvements to ProPilot (v2.0?), better cameras (especially that rear backup cam). Maybe even multi-link rear suspension for better ride/handling. More powerful single motor >110kW and possibly dual-motors (AWD) optioning.
There is so much more they could do for Leaf 3.0 that the pricing will have to reflect that. To compete with SR Model 3 @$35K, Nissan will have to step it up for that game.
My 2 cents.
New Leaf Owner: Just ordered Feb 24 2018, 2018 Leaf SL in Jade Frost. Expected ETA by May 30 2018.
