LOL My F 150 Lightning gets like 1.7 - 1.8 when it’s really cold. Still way cheaper to operate than any gas powered F150. It’s all relative to what you are driving. What you are getting is excellent
That's a good test. I do the opposite in my Model Y LR. I wanted to know what was the impact the other day starting from a cold battery and hopping in without first warming up the cabin. My car had been parked at work for more than 8 hours. My drive home was about a 30 minute commute. In my case with some stop and go traffic there was a 2% difference from when I conducted this same test this past summer. Personally I'd say that's pretty good. Yes, an EV will lose some range/efficiency in the colder months and people against EVs think that's a goctha but it isn't. An equivalent gas car to my Model Y, say a Rav4 or even a Rav4 hybrid, is already 2x to 3x less efficient than my Model Y. It's even less in the colder months because gas cars are less efficient in the winter as well. Most don't notice it because they don't focus on it at all and just simply go fill up when they get low. But a typical gas car already being less than an EV can be upwards of 30% less efficient in the winter. This isn't to say one should choose and EV over a gas car. I still have a gas car the wife uses for work a couple times during the week. So drive whatever you like. But I'm just trying to show that the efficiency hit isn't what people think it is if you're not doing a comparison.
Couple of thoughts here. 1. I was wondering if cold weather helps gas vehicles because of more dense air coming in the engine. I asked AI about that, and it said actually no. The increased air density has a much greater drag effect on automobiles. Turns out some at least some of your loss is increased air density. 2. If you have an iphone, there's something built in to iOS called "ShortCuts". In there, the Tesla app exposes many functions, among them is battery preconditioning. This is the only way I've found to actually force a true precondition. Turning on the climate, only does it for as long as it takes to heat the cab. And the only other way to do it, is driving to a SuperCharger. I have confirmed that doing this method takes forever, and truly warms up the pack, without a destination! Try it!
Can you convert all that to English please. How much less range does the Tesla have in the test you performed vs in 70 F temps. Was the Bolt more or less efficient than the Tesla in the same conditions. Don't care, or know about "heat pumps", or Wh/mi.... Thanks!
I have been using the scheduled departure preconditioning and it seems to help with the efficiency for my local travel. And on the holiday road trips this year in the cold when driving long distances the heat pump makes a difference, BUT if navigating to a Tesla SC and preconditioning kicks in that advantage evaporates pretty fast, but it does charge like it is supposed to even in winter temps. So it turns out to be a wash after preconditioning. It is rather depressing watching the SOC drop like a rock when it does that. Overall it does what I bought the Tesla to do. The Bolt had no concept of pretrip preconditioning, on road preconditioning, and my charging speeds were in the 24-36kw range at a DCFC during my holiday trips last year. This year the hold up was not the car, but chargers, and congestion issues. Had to punt to plan b on the trip out and on the trip back.
I have not noticed any difference in efficiency in my Model Y driving to work in winter. But the drive home shows a big jump in energy usage as my car has to sit outside at work. At home, it is parked in a garage which is climate controlled.
It takes longer, whilst plugged in, to warm the HV battery for it accept regen. The car should be scheduled for departure at a set time, at least several hours before departure, preferably sometime during the previous evening.
I agree that efficiency in an EV is important. And that you lose it in the cold winter. This issue, isn’t really a problem now, since the improvements in the industry have occurred in the last 10 years. My 2011 Nissan Leaf could make that commute one way. It would be doubtful it could do a round trip without a charge. Time marches on. EV’s improve. As Luke has shown. (The Fiat probably wont make the round trip without a charge, either.)

The one thing I stopped worrying about when I got an ev is being efficient. Its already efficient enough for me.
Hear hear.👍
Try lowering your heat setting to 68 f. And heated steering wheel and seats at lowest setting. That's what I run in the great white north in michigan.
Exactly!👍

Will do
Thanks. Good info.
Nice brief, thanks.

Bolt was less efficient in these temps.

How well does the heater work does it get warm or hot on the inside
Plenty warm. It can get hot.

Correct. Rachel tried the next day and needed a charge
How are we at 19 degrees with standing water by the underpass? Just asking.
That underpass always has water and it is moving. Also a good amount of traffic. There was some ice, I don’t know if it showed up
really cold?
For here
Gas vehicles are already more expensive to operate and less efficient they lose around 15% in winter months.
If you notice, they make ONE model EV and then discontinue it. More evidence that EVs are planned obsolescence disposable cars.
??? Tesla has 5 different models in production including the Model 3 since 2017; it has been updated but not cancelled!
