It's true that I called out Nissan for the 100 mile claim from day one, but that wasn't because of any bias. That was just because of the numbers. We know for a fact that a standard mid-sized vehicle uses 220 wh/mile on the Urban Cycle... So tell me how you can get 100 miles of range out of a 24 kWh battery (estimated 19 kWh usable) using 220 to 395 wh/mile? The fact is you can't. Numbers don't lie...
The LEAF battery pack has about 20.5 kWh usable.
BEVs utilize regenerative braking. ICEVs waste this energy by converting it to heat, so of course they use more wh/mile, comparing vehicles of identical weight and drag.
To get 100 mile range in a LEAF, you must average about 4.9 m/kWh. Not possible at freeway speeds, but often achieved in a variety of urban (and rural) driving conditions.
