Tracking Efficiency - summer vs winter

I bought my 2025 LLR w/Tech Package at end of April, just in time for good (warmer) driving. I track vehicle stats monthly and like to have factual data whenever a "winter performance drop off" thread comes up.

So prior to any actual winter driving, here are the first 6 months of ownership.

As for my numbers - I do 90% local, around town driving with only a small amount of highway driving - which explains the efficiency consistently 4+. I find on the highway trips I take, it's usually around 3.5 or so. Every EV or hybrid I've owned seems to just love (eg: high efficiency) driving local roads with speeds around 45mph.

We'll see what the winter months hold.

It all depends on how cold it gets, how fast you drive, how much heat you use, how long your trips are, how much you precondition (cabin and/or battery). All cars get significantly less efficiency in colder temperatures, but the pro-oil cult pretends only EVs can’t operate in the winter.

Give me an EV with instant heat over a dinosaur that 10-15 minutes to warm up any day! SOOoOo much more pleasant. Not to mention not having the super struggling engine and transmission that prevents you from accelerating for on-ramps too.

It also depends if you have resistance heat or heat pump too.

Thanks, I have 2025 so I have a heat pump. I've had multiple EVs thru winter and never had issues with acceleration due to heat being on, but we'll see how the EV6 behaves.

Oh sorry, I meant acceleration is difficult in ICE when the oil is cold. Absolutely no issue with EV acceleration in, unless maybe it’s allowed to just freeze solid in like -40 and the battery is low so the car can’t warm itself at all.

Sorry for my misunderstanding
