AutoNews has an article showing the road map of Toyota, Honda, Nissan (and their luxury brands) till 2019.
According to them, Leaf 2 is coming out in 2018. And Infiniti LE in 2019.
It is not clear whether they are talking about Financial Years (Nissan's ends in March) or Model Years (which start anywhere in the earlier year) or calendar year. If it is the Model Year, that is not a big delay - since Leaf 2 was supposed to come sometime early 2017. But if this is the calendar year, then Leaf 2 is delayed by at least a year - and may come after even Model 3, let along Bolt.
Leaf: The electric Leaf's driving range will expand for 2016, with a 30-kilowatt-hour battery delivering between 110 and 125 miles per full charge, compared with its current EPA-rated range of 84 miles. But an even bigger performance gain is coming with the Leaf's 2018 redesign, according to a person familiar with the project. A battery-power system is being developed that could give the new generation more than 300 miles of driving range.
Infiniti LE: Originally proposed as a rebadged Nissan Leaf, the on-again-off-again Infiniti electric car is back in the longer-range product plans for now. Nissan executives recently told shareholders that the automaker is developing an electric-vehicle battery system that could provide a driving range of more than 300 miles per charge. The likely 2018-19 time frame for that technology is a likely bet for the Infiniti EV.
