That makes me curious, would turning off one of the axles save some energy or would it be a wash because the "disconnected" motor would create "drag" on the wheels?
It would probably be a wash.

That's what mine actually does at high speeds - front motor is an async machine that is switched off unless used for acceleration or regen braking, for cruising only rear motor is used as it's more efficient by design. Front motor assembly is still always there as added weight, and the front driveshafts and diff (and the unpowered rotor of the motor) still spin, which costs a tiny but ultimately non-zero amount of energy.That makes me curious, would turning off one of the axles save some energy or would it be a wash because the "disconnected" motor would create "drag" on the wheels?
Consumption on the roadtrip was between 160-170 Wh/km on average, got up to 180 with the highway blast to Ringmeet and the activities there. Lifetime average of the car is 191. It seems I have something of a heavy foot and drive highway rather a lot, which in a BEV increases average consumption noticeably. RWD Model 3s seem to be much more efficient, too - I've seen people quote numbers in the 140-150s for highway driving in the SR+.
So far, that hasn’t ever happened to me. What did happen was the opposite: „Sorry, I’ll be right back - need to go unplug the car, it’s already full and will accumulate blocking charges while we finish eating unless I move it“.How soon will it be before “I’m sorry I’m late but my car took forever to charge” becomes a clichéd excuse?
I've been asked this too since I went electric and the answer is never. I have a very slow home charger but even then, a couple of hours is plenty to get it half full, and I do need atleast 5-6 hrs of sleep anyway which is plenty. You just need to remember to plug it in every day. It really is a non issueHow soon will it be before “I’m sorry I’m late but my car took forever to charge” becomes a clichéd excuse?
