For “getting out of Dodge” as the well-worn saying goes, an EV is likely to be a better bet. Even if you’re stuck in traffic on the way to the shelter, you won’t be much better off in a gas car. EVs don’t idle, so if you’re not moving, you’re not using energy, except to run the AC or heater.
ICE vehicles do have one advantage in the aftermath of a disaster—you can always store extra gas in cans. On the other hand, an EV such as the Tesla Model X, the Hyundai Ioniq 5 or the Ford F-150 Lightning, is capable of towing a generator, which can be used to charge up your friends’ EVs.
EVs would seem to be the winner when evacuating in the path of a hurricane, but gas vehicles do have a slight advantage when returning to the disaster zone to offer assistance.
