Re: @Zog
Confirmed for a Mitsubishi Phev - 30miles reported range - usually get 23-24 in the summer not using the AC.
Winter? 18 miles if lucky, and even then the 2 litre generator kicks in until the batteries have warmed up (if temp below 10C).
But you can pre-heat the cabin by remote before unplugging it from the mains in the morning!
