Does anyone know if Ampera uses motor heat to help with cabin heat, or is it purely just electric heating ? (Speaking on course about pure EV operation)
Thanks

It has a heat pump, and the engine will switch on if you've set it to do so when the temperature is south of freezing.

No heatpump but if the ICE runs then the cooling water is diverted to warm the cabin (if needed).

Otherwise heating is electric, there is no attempt to use any heat from the electric motor coils.

When cold its often better to run in hold to start with, get the cabin warm and then switch to electric. the residual heat in the engine cooling circuit will keep the car warm without using the traction battery.

There is a mode called ERDTT "engine running due to temperature" which can kick in when its very cold - can be set 2 or -10 deg on the MY13 and this idles the engine to provide heat. Rarely seen in the UK.

If you're feeling really stingy on a long trip. you can drive in Hold for a bit, heat the cabin to say 25C, then switch to Normal for a few miles & turn the fan right off, which will stop any electrical heating. This way you make sure all the leccy goes into motion! Then, as your toes start to freeze, switch back to Hold, turn the fan on once the ICE kicks in, and repeat!

(Not a good tactic with the missus on board, though...) :eek:
