With a full charge, I start the car and it says I have 280 miles available. If I turn on any climate control that causes the fan to run, the available milage drops by about 25% (210). Turning on heated steering wheel and heated set does not alter the available milage, but I suspect it must affect it, since it is burning electricity. I would be happy with just heated steering wheel and seats, but with an outside temp around 30 degrees, the inside keeps fogging up. I've never had a car that liked fogging up as much as the Soltera. This causes me to keep messing with with the defrost. Maybe I just need to accept this as another cost of winter.
