Yes. You use twice as much electricity to go the same distance. Gas cars lose efficiency in the cold too, but it’s less drastic. Only stats I can find are 15%

Yes. You use twice as much electricity to go the same distance. Gas cars lose efficiency in the cold too, but it’s less drastic. Only stats I can find are 15% loss at 20F (which is a lot warmer than -4F). Also, charging tends to be much slower in the cold as batteries need to be warm to accept full charge rate. If you’re cruising on the highway it’s usually not too bad, but if you start from an overnight stop and then try to immediately charge the car you could be waiting for the battery to warm up.
