For road trips only up the charging speed at DC fast charging stations and up the speed from 80 to 100 please!
For daily driving keep it the same. And please add a heat pump.....for winter driving! If you do this you will kill the MY.
I don't think a heat pump is necessary just yet, until they can finalize a fool proof design. The Mach-E battery is gigantic and the mileage is very accurate compared to the MY. Also, the battery is currently limited to 88kWh so eventually they'll open it up and we'll get even more range. MY's are notorious of having heat pump issues as soon as the weather gets below zero. I think more engineering needs to go into the heat pump design to make sure it lasts when it needs (below freezing). A MY owner at my work hasn't had his car for over 2 weeks now because we had one day when it was 20 degrees and his heat failed. Now he's in an older M3 with a resistive heater for the time being.
