I didn't realise that either. Suppose you have driven entirely in EV mode, say for half an hour, will the engine still require warming up before you need the power for an overtake. Or does the battery keep it warm, perhaps with an oil heater, even though the engine is not running?
It is a difference between my previous IC cars where the power output is the same and the hybrid where there is a noticeable difference between EV and HV.
