Cold weather can cut range 20-40%. Precondition while plugged in, use seat heaters over cabin heat, check tire pressure.
The biggest winter range killer is cabin heating. Seat and steering wheel heaters use 10x less energy than the cabin heater. Precondition while plugged in so the battery and cabin are warm before you leave. Keep tire pressure at spec — cold drops it ~1 PSI per 10°F. Snow tires with the 3-peak mountain symbol are a must in snow states.
