Are updates making Wh/mi worse?

    Over the first few months I have been averaging around 450 Wh/mi in the winter here in NJ. Over the past few weeks my averages are climbing quickly and I am now seeing over 600 Wh/mi trips. I have not changed anything and weather has been as cold as it was in the past and lows around 17. Is anyone else seeing a much higher consumption after the past few updates?

    A few quick suggestions picked up from experience and several threads here which have worked well for us:

    - ensure resting cold tire pressure is topped up
    - warm up battery by charging for at least an hour prior to driving
    - if you can live with it, use heated seats and manually set heater fan speed from auto to 3 (this alone can have a very significant effect)
