I think most of us on here with a conventional petrol or diesel car would show some mechanical sympathy after a cold start and treat the motor gently until normal water and oil temperatures were reached.
If you have a PHEV running on battery on a cold day, if you demand maximum acceleration and the petrol / diesel kicks in, presumably the engine will instantly spin round to maximum revs, straight after firing up, which seems madness for engine longevity.
Is there some form of 'pre warming' or coolant circulation when its running on battery, which means that when the engine does kick in, it's effectively not a cold start?
