Averaging 1.5 mi/kwh @ 32 degrees down from 1.8 mi/kwh last year.

This was my drive to work today . Truck was in garage plugged in and set to warm cabin at 5:30 am. Seat warmers on and heat set to 75 degrees. I say pretty darn good at 21 deg temp sport mode .

you must drive City or like a grandma. I have never seen that kwh. I'm 17 miles to work highway and even summer is lucky 2.3. I had a 2022 and got 1.6-1.9 in cold winter with temp set 65. my 24 with heat pump temp set at 72 I'm seeing 1.7-1.9. daily average seems a little better but it don't matter I charge up daily. But yes I got those tires on my 24.

LOL This was back roads and about 4 miles of interstate at 70mph?

Correct me if I'm mistaken, but it appears the Standard Range's (SR) are getting a bit better mi/kwh than the Extended Ranges (ER). Probably due to weight.

Small sample size, multiple variables, fuzzy memory. Unless you have actual data it's going to be hard to figure out any difference.

Your mi/kW seems pretty normal for those temps. Similar to what i was getting last winter when I was in KY. I'd be surprised to hear you were getting 1.8 at hwy speeds at similar temps. I was barely getting over 1.8 in warm weather at highway speeds.

Averaging 1.5 mi/kwh @ 32 degrees down from 1.8 mi/kwh last year. As the title says efficiency has gone done by more than 15% compared to last year. This is highway driving, no preconditioning. AC set to auto 1 @ 65 degrees.

The only thing different is the set of tires. Last year still had the original OEM AT Dynapro tyres. This year I have the OEM Goodyear Wrangler all season tires which are supposed to be EV specific.

I thought the tires would be better for efficiency, so I am not sure why the efficiency is lower this year.

Is anybody experiencing something similar? As the battery ages, does it become less efficient? (As a system: coolant, pumps, cells, etc)

thanks

It sounds from your post that you own an antimatter blue lightning.
This is my experience with my truck couple days ago traveling to Asheville to meet family and drive thru a section of the BRP. On Thanksgiving day, I drove I85N to NC on a new set of Michelin Defenders EV compatible rating.
Here are my numbers. Thanksgiving day, outside temp at 52deg. The truck got preconditioned and was ready at 7am. Remember, the Lightning has new tires and I wanted to know what kind of an efficiency loss I would get. The temp did not change at all until I got to the SC in Salisbury NC. To my surprise, I had a steady 2.2 mpkw. Yes, 2.2mpkh. Speed set at 70mph thru out the trip. Temps were set at normal/warm. The return trip was 2.0 mpkw. Temps at 48 until we got home. Next day we climbed the road to Asheville and BRP. Only two sections of the BRP were open and drivable. Outside temp at 46deg. Started with a preconditioned truck and 2.0mpkw and ended up with 1.6mpkw at our destination and a temp of 38deg. Coming back and of course going downhill with temps now at 42deg, we averaged 2.1mpkw with a lot of regenerative energy.
The tires had very little or no influence on the efficiency loss of the truck and my concerns basically were alleviated.
What helped is the preconditioning of the truck. It does and if you going to live in colder climate regions, should be a scheduled event with your truck. Heat the battery, heat the cabin and enjoy your rides in the winter.
Good luck.!!
