Let's say I am planning to drive 700km mostly on freeway( 424 miles ) , stay over night at motel for 2 days and then return trip back , another 700km. total driving 1400km ( 850 miles) Hoping that will not find charging station at motel most likely and have to fill up gas for at least two times. In above scenario, what is the best mode to be selected for efficient green driving ? I am thinking: drive first 20 to 30 km in Econ Mode and rest in HV mode.. This will preserve the battery for longer term for HV mode. Does it makes sense ? Any suggestions are welcome , thanks.
