An interesting little bit of data from fleetcarma that seems worthy of a closer look.

How interesting that even though EV's suffer greater range loss in colder weather, electric vehicle payback actually improves at lower temperatures. My guess is that both are related to the lower efficiency of converting gasoline to forward motion: temperature effects on range are partially masked by these inefficiencies in ICE vehicles, but the cost delta of these cold weather effects is still greater for ICE than EV.
