Lifetime Average Wh/mi

[huzz1970]

Hi to all
I have not reported in some time. I am driving about 55 miles per day, 75% highway at 70-75, gentle rolling on the highway. 14500 miles in 10 months, averaging 283Wh/mile. One of these days I will post a picture of the dash.

I drive mostly highway miles on 80-90 mile round trip each weekday. Lifetime average is 280wh/mi. but for some unexplained reason I've been averaging 264wh/mi lately. In the past my averages have not strayed too far from 279-280.

Perhaps your tires are wearing so far that the rolling resistance is dropping quickly... when did you change your tires last?

FWIW, I was seeing nearly the exact same efficiency stats, and also at ~31.5k miles, with a big drop this month. Had the car in for a tire rotation 10 days ago -- and the tread measurements were low. I replaced the tires this week (tire rack has the stock 19" Goodyears at $100 off; even paying for shipping and a local shop install made them $300 less than Tesla's price...). I've only had a couple days commute on the new ones, but am seeing a 20-30 Wh/mi increase on the new tires.

So you likely need new tires soon...

I'm down to about 360w/mi in the hilly Seattle area after about 2700 mi., some of which was in below-freezing weather.

After 25k miles, my P85 / 21” is now at 356Wh/mi, though for the past five miles I’ve had a perpetual motion machine!

The subzero temperatures are causing brutally high numbers which are bringing my wh/mile average way up. (I'm not seeing the >1000 numbers I saw on the Michigan trip with the gunked-up wheel wells, though!) I will probably post another lifetime average in the spring...

Happy March! I am more than ready for some nice Spring weather and my all-season tires. Feb 2015 may have been my worst month yet for Wh/mi.

Great efficiency last month after upgrading to firmware 6.1, 2.2.139+ for the D; includes a roadtrip to Squaw Valley, Tahoe as well:

Here's the first report on my lifetime average in the P85D, after 5245 miles: 1720 kWh, 327 Wh/mi.

Many of those miles came on two road trips, both with snow and cold temps for part of the route. Perhaps half came under firmware .139, which was the first release to fully implement torque sleep on the second motor. All the miles so far (but for the first 100 or so) have been driven on 19" wheels with Hakka R2 snow tires.

The photo below is from a few days ago, when I had a nail in the front right tire...

Whoa! I just had a low tire but it didn't tell me which one!!!

Newer TPMS sensors - they changed a couple of months ago - at work, I believe.

You think your February was bad, my solar panels have been covered in snow since the late January blizzard.
This is the first time they haven't cleared after a day or two. My daughter claims we had a MEGA avalanche yesterday
but when I got home today the pack hadn't changed significantly...(snowing now too)

So, not only have we had extreme cold but I haven't been able to power my car with the sun.

My Feb. numbers:

I noticed that I've improved a little last month over my lifetime numbers!
P85 21" wheels...
