Could be tire pressure. When temps drop, so does tire pressure, which increases rolling resistance.
Could the e-brake be partially engaged? Happened with my old car sometimes, though it’s a long shot on a new truck.
@Thyme
That’s a stretch, but I guess possible on any vehicle.

Brake calipers can stick even on newer vehicles. Just another idea to check.

It’s unlikely but worth considering, especially if all else checks out.
Your speed and averages matter. One trip won’t give you a full picture.
I’ve driven 80,000 km through Canadian winters, and the worst range loss I’ve seen is around 30%. You may be overthinking it.

To clarify, the 1.1 average is based on the past five days (291 miles). Not really worried, just surprised at the steep drop.
My speeds are mostly 45 mph or under, maxing out at 55 mph for a few miles.
@Micah
Yeah, something’s definitely odd here. 1.1 mi/kWh at those speeds in 20-30°F doesn’t add up. Even with the heat set at 72°F, I’d expect at least 1.5 mi/kWh based on my experience.

I think tire PSI was a big factor—mine was at 33 psi. I’ll pump them up to 42 psi and see if things improve.
@Micah
Good plan! Low tire pressure can have a big impact on range.

He said he’s only going 30-45 mph.
@MarkDuke1
Fair enough. I still think more data is needed before deciding something’s wrong. Averages matter more.

He’s noticing a major efficiency drop and wants to make sure it’s not an issue. It’s not about averages; it’s about addressing a possible problem early on.
@Tilden
Point taken. He should keep tracking it and see if it stays that low.
Have you checked the energy breakdown? You should be able to see the percentage used for driving, cabin heat, etc. Could give you a better idea of what’s draining the most.

Didn’t realize that feature existed! I’ll take a look. And no, I’m only preconditioning in the morning while it’s on the charger.
@Micah
Check under the truck apps; there should be a trip breakdown that shows energy usage in categories like interior temp, exterior temp, etc.

Good question. Speed plus cold can really eat into efficiency. I’m in a cold region and get around 1 mi/kWh at 80 mph in 0°F conditions.

Max speed is only 55 mph for a short stretch. Rest is 45 or below.

Check your tire pressure—low pressure could be causing a big efficiency hit.
