The petrol engine operates quietly, making it difficult for me to consistently perceive its operation. In the vicinity, it hardly activates until I fully depress the accelerator. It typically occurs on the highway. At highway velocities, the battery depletes rapidly, particularly on inclines, prompting me to use the Hold mode on ascents. There exists a somewhat unreliable function designed to use the destination's location for managing electricity consumption. However, it often fails to activate when required and sometimes powers down without my awareness until the battery is depleted, hence I do not rely on it.
