This time of year I do two trips a month between my home in Markham, Ontario to my cottage up near North Bay. The trip is about 290 km (180 miles) one way. I typically leave with a full charge, let the battery range drop down to zero at which point the ICE kicks in. Pretty much immediately I select HV Charge mode. Over the next 40-60 minutes of highway driving I end up back to about 60% charge at which point I switch back to EV mode and drive on battery until its back to zero km, then back to EV Charge mode again, repeating this until I arrive at my destination. I do a full change at 120v when I arrive so that I can do trips into town on battery and so that I have a full charge on the battery when I leave to go home. Returning home I pretty much repeat the process on my return trip. On these trips I've been averaging between 2 and 3 liters per 100 km (80 to 120 mpg). I am curious if others have tried this technique on long trips and what your experiences have been like. FYI, I typically drive these long trips using the ACC (cruise control) set for maybe 5 to 10 km/h above the speed limit.
