ya my 95 km speed on 7 to Ottawa was great but my 125km speed Ottawa to Kingston was eating batt and then Kingston to Toronto 115 was much better. I did a fast charge in both directions but I just watch the km readout on the app and only charge what i need to get to my destination. Was easy and flawless experience and bluecruise was awesome. My math said I could have made it via hwy 7 from Richmond hill to Ottawa but there are no fast chargers for a very long stretch on hw7 so I chose not to chance the guessometer and make sure I had plenty to get there in the dead charger zone.
reduced ranges people are posting are very real at higher speeds in a blunt nosed truck, I am not sure "yet" what the optimum max speed is but seems like over 100 km speed is max for not losing range so you have to balance range vs charge time which is better 30 min charge or slow down and maybe make your trip without a charge stop, if you have to stop regardless then I choose more speed.
Tesla's are ripping by me guess better aero makes less loss at speeds.
