Winter fuel efficiency in EVs falls behind petrol , diesel and hybrid cars . Mileage in conventional vehicles falls about 12 % at temperatures below 20ºF compared to a 34 % drop in hybrids while research shows the distance travelled by diesel was 57 % on a single charge than at 75ºF. In addition to weather - related inefficiency , cabin heaters can drain large amounts of electrical energy . Experts recommend , often via smartphone app , heating the cabin remotely using electricity from the grid prior to travel , or using seat warmers rather than cabin heating .
