Okay. The reason I ask is w/r/t range there's only a .4 mile gain on a full charge. Less than a half a mile didn't seem worth it to me.

Just another reason to use percent over range ;-)
The referenced empirical data suggests that range mode on dual drive cars adds around 20 miles / 30 km's of extra range for a full charge. Your results may vary.
Can you point me to your reference? I'm not seeing that kind of improvement on my car, not even close.
Keep in mind the comment came from Calgary. It probably does NOT make that much difference in SoCal.

I don't have a P85 reference, this P85D is my first Tesla (thought I've had it for over a year and a half).
I'm pretty sure I don't have alignment issues as I've had it aligned 3 times since I've owned it: once when my rear suspension was replaced, once during the yearly service, and once after the radar was realigned (causing driver assistance errors).

My reference is based on the 7% quoted from the video in my previous post here:
Firmware 7.1
Not sure how it would make a difference. In fact, the way torque sleep works is by using the more efficient front motor. In adverse conditions, like snowy winter roads, the rear motor would be kicking in for stability and acceleration.
I thought you said your wife has a P85. Maybe I misread. If that's your only Tesla and you've got that high consumption, it may be just the way your driving or the locations (up and down hills). Have you actually tried going on a stretch of road (say 5 or so miles) with another Model S driver to compare?
The alignment was the only thing I could think of off the top of my head that hopefully is an old issue. I guess the ultimate way to know is check your tire wear. The rears will always wear the inside slightly more than outside, but the front do the opposite (they wear the outside more than inside when turning). So after the tires have visited the front and back, they should have even wear across the tire.

I normally get caught up on a thread before posting, but I'm not doing that this time, so apologies in advance if anyone has already pointed this out.
That video was made over a year ago, long before Auto Steer was available. I pointed out in the notes of the video that I was driving in a way to induce the lane departure warnings, as I was trying to make a video that would demonstrate the problem. So I was purposely driving close to, but not over the lane markers to show that the departure warning sounds unnecessarily at times. If it so happened that in some of the instances there was some micro-paving, I'm sure that's more a coincidence than anything else.
Now that auto steer is available I agree that these are not the kind of roads it works well on, and I don't use it on these roads. In fact, I said that in my post that started this part of the discussion, here:
I'm glad you agree that the car is alerting too much in the video. Those roads are fairly narrow, and keeping the car dead center in the lane, which is what the current lane departure warning system seems to require, becomes annoying over time. A sensitivity setting would solve the problem.

Range mode can be turned on in Insane Mode and Ludicrous Mode.
Also the efficiency benefits of torque sleep are not limited to range mode being on, as per Jerome Guillen. Those benefits are increased with range mode on, but some of the efficiency benefits of torque sleep exist even with range mode off. So while I only watched a bit of the video you referenced, the validity of any conclusion reached in that video is questionable if they were operating on the premise that range mode is required for there to be any efficiency benefits from torque sleep.

My wife and I drive in much colder climates than either of you guys, and have a much better Wh/mile number, so I guess we're just driving like wimps! Through 29,483 miles our lifetime Wh/mi is 325. (Photo is from today's trip. I still record certain specific trips we take.)
I'll add that the main trip that we each take is in my case the near 60 mile trip shown, and in hers a few miles less, with approximately thirty to thirty five minutes of each of those trips on a 65 MPH interstate where we each set the TACC to 70. So while we may be driving a bit on the wimpy side, we're not driving 55 on the highway or anything.

Yeah, I've not seen sub-300 Wh/mi in ages, except in places where it's significantly downhill for an extended period (like from Makoto's in Boone to my house... loss of like 2300 ft elevation). Even then I don't get anywhere near what others seem to get.
I do drive with the AC on ~69F, and with the flow of traffic in the fastest lane, usually. My speed of choice locally is usually 78 MPH on the highways (speed limit 70). But even the last time I *really* tried to get good efficiency I basically tailgated a tractor trailer at ~62 MPH or less for ~50 miles and still only got 254 Wh/mi. Maybe I should do some more controlled testing and possibly get Tesla to investigate a bit depending on what I come up with.
Yesterday I drove over 100 miles, pretty conservatively. No hard accelerations or passing or anything. Here's what the car says:
EV_tripCharge_Miles,111.038
EV_tripCharge_kWh,36.440
EV_tripCharge_whpm,328.180
I tried one way with range mode on and one way with range mode off... made no real difference (95% interstate).

Got it last night. But just brought the car in this am for 25K mi service, so not enough time to notice anything new.

Updated to 7.1(2.24.102) yesterday. Lost Slacker & had to reboot.
Any word on what 2.26.150 changes?
@maximus16 - I see you have an 85. Can you please note the power output around 50% SOC next time you go to a SpC? Trying to get more data on a possible taper algo change.
Ha! I haven't wanted to spend the $ on the Power Tools app
I am a cheap ass when it comes to that. lol!
SC to 100%, did 4 0-60 launches with max power at 342KW
When I go to Dallas again, I usually SC to 50-60% and can get some data then

note that you do not need any app for this. You can read the charge voltage and amperage directly from the charge session screen.

Just finished installing 2.28.19. Surprise! Nothing new in the release notes. Didn't notice any changes, but haven't driven it yet.
