You are right. Last week was very windy in my area. Consumption went up to 18.5kWh/100km from 16.5kWh/100km. Similar outside temperature, same commute, but rain and wind :(
Hi, my dealer told me that adding DC port will cost about 4000$, so the price of a base + DC is higher than a Luxury model. Not interesting when you buy a new car but an option if you are buying a used base model.
