Effect of cold on range

[cpobuyer]

I have recently bought a 2015 P85D with 43k miles on it. During my commute this morning (6am), when the outside temperature was 39F, the watt per mile was about 140 higher than the usual. Normally, on the same commute the car takes 350w/mi but today it took 490w/mi.

Is this normal or should I get the car checked as it’s under full 4 year warranty?

That sounds about right. How long is your commute? It takes a while for the battery to warm up.

It’s about 30mins

It’s about 30mins

That's about how long it takes the battery to warm up. After 30 minutes the wh/mi will improve, but they'll still be higher in cold weather. Here's a useful article:

Fortunately in the San Francisco area you don't have to worry about temperatures like that too often.

Thank you

I just wish we could finally get a feature where we get to set the "charge complete" time instead of the time to start charging. Then in the cold weather your battery will already be warm when you go to drive your car.

CPO, I drive about 30 mins also and I've found that using Range Mode helps a little but you will be Regen reduced for about 20 miles. For those of us that aren't dealing with very cold areas it helps by it not turning the battery heater because it lowers the set point of it.

There is always impact of cold on the range. Everyday when we have below 40 F in Philly, the consumption goes up:
