If you restict the mode to electric only you’ll notice it being underpowered, but if driving it in a normal mode where the car decided which drive type it’ll appear completely seamless. Remember the total output of the electric motor in a PHEV isn’t like driving a BEV where the motor will be much more powerful.
In winter you’ll probably find that the engine will start up & run to power the heater, it certainly does that in the Niro PHEV.
