Range anxiety is the biggest con of any EV today. Even though companies are constantly improving range figures and charging times, the fear of a depleting battery is still one of the biggest reasons why people are apprehensive to make the shift. Things get worse when it comes to hauling and towing stuff. Since towing or hauling anything puts extra stress on the powertrain, the range is bound to take a hit; and Audis recent experiment just proved the same. So, as far as utility is concerned, EVs still have a long way to go until they replace internal combustion engined SUVs and trucks in all senses.
