Yup , context is king.^ It's worth noting that those figures in the previous post are probably at higher speeds.
I'm seeing 200wh/mile @ 45mph in a Leaf, and 300wh/mile at 60mph.
One of the better published examples of how it isn't just 1 number at any speed .. is this Link for Tesla.
85kwh Model S and a 55kwh 1st Gen Roadster
At the same 50MPH steady speed:
I used about ~179wh/Mile , even with about ~30% of that for ICE parasitic losses.
The 55kwh Roadster showed about ~211 wh/mile
The 85kwh ModelS showed about ~254 wh/mile
I couldn't agree moreEven so, it's pretty astounding how efficient the Insight chassis is.
