Unless you are coasting long distances,you will not see ev time on the highway. You will not see great mileage at 80+. You make the choice. Less time to get to where you are going. Including maybe heaven. Or great mileage.I'm on my second long road trip, mileage is not up to previous experience. This trip we are pushing the speed to 80+ and seeing the mileage drop to 24mpg. I'm thinking this is a big vehicle and the drag probably becomes a factor over 80mph. Also not seeing much EV time on the Interstate at high speeds. I wonder what the speed Acura is using for their highway rating of 28mpg?
