FWIW, Nissan has stated a target of 600kms in the Japanese JC08 cycle (Tokyo cycle, very generous to EVs, brutal to normal ICEs) Global Newsroom
The 30kWh LEAF is 280kms JCO8, so the target for the LEAF 2 is 600/280 = 215% of the 30kWh version
since much of the improvement is aerodynamics, this should increase the hwy range more than the cty range.
i.e. hwy range increase considerably more than 215%
Using the 2016 fuel economy download, I've added an expected Nissan LEAF 2, and then sorted by range. The results are that the 60kWh LEAF 2 should approximate a RWD 75kWh Tesla Model S, or an AWD Performance 90kWh Tesla model X.
I suppose this is similar to saying that a Prius is 50% more fuel efficient than a 7 seater RAV4 hybrid/Lexus. Similar tech, but size matters. Compare Side-by-Side
