I think the range and performance will be very similar to the Leaf. In fact it might perform slightly better in 2nd as the ratio is larger and overall I think the car will be lighter than the Leaf!

Personally I don't think range is the issue anymore, my thirsty V6 only gets about 400 miles to a tank, and I neve drive that far in one go. The problem is re charging, that has to improve massively. Down to a few minutes and with infrastructure everywhere.
