The electric range is only around 72 miles. They say that if you drive on the highway at speed, the range can drop to the low 60 miles! Fortunately, the car can charge from 7% range to 80% range at a DC Fast Charger in about 22 minutes, assuming the DC fast charger can supply enough electricity. I'm starting to do excel spreadsheets that calculate the amount of gas used and the amount of range used for my typical excursions. A trip from my home, assuming the 1.9 gallon tank of the i3's gasoline tank is full and the battery is fully charged, driving highway to wine country, will necessitate charging at the wineries in order to make it back. There is a small chance that the car may need to have its 1.9 gallon tank replenished, as much of it will be burned off on the way there and there might not be enough to ensure a safe return.
