After about a year at 298Wh/mi on my P85, today I finally had it fall to 297Wh/mi. 40,500 miles. I've been patiently waiting and I found it much more exciting than is reasonable.

Hit my 2nd year anniversary with my Model S 70D last Saturday. After 2 years, my 70D has traveled 22,728.9 miles, using 7351.8 kWh, for an average of 323 Wh/mile according to the car's trip data.
I am retired so I have no regular commute. My travel is a mix of lots of local short trips around town, longer trips in the local area, and a few longer trips. Our longest trip was from the Boston area to Maryland and back.
The average energy use (323) is 10.6% over the rate implied by the EPA rating (240 miles, 70 kWh). I don't feel too bad about that, because energy use is considerably higher than the EPA average would imply in the winter here. It is not unusual to see 5-mile average rates of 400 Wh/mi or more when running errands in the winter.

After 19 months of ownership here are my P90DL's numbers
Current Month September
Distance in Miles = 1069
Total energy kWh = 335
Avg energy / Mile in Wh/m = 313
Avg Temp 70.2 F (from TeslaFi)
Lifetime (19 Months)
Distance in Miles = 23,655
Total energy kWh = 7614
Avg energy / Mile in Wh/m = 322
This month's data reflects warm weather driving with no use of cabin heater, heated seats and steering wheel as well as defrosters and almost constant use of air conditioning. Battery degradation since new is about 3% at 90% charge (241 new vs 235 now). Summer tires (Bridgestone Pole Position S04 19" and Cyclone wheels). Normal daily charge level of battery is set to 60% due to my daily use case.
Range Mode OFF entire month and on firmware for most of the month 2017.32.6 CA28227 then 2017.36.1B27C6D as of 9/21/2017.

3,000 miles now and still up at 352 wh/ml.
I just can’t resist putting my foot down!!

289 Wh/mi over 110,000 miles.
Looking back at my records, we must've had a milder than usual winter last year because my lifetime average never rose up after last year's low of 298 Wh/mi. It dropped steadily over this year.

There's a huge difference in wh/mi across this thread. It might be an idea to quote whether you have 21" or 19" , AWD and facelift or not.
I personally have 21", AWD and facelift model, and drive as carefully as I dare, I cannot get below 300 wh/mi on a 'since last charge'. How you guys who are AVERAGING 289 wh/mi over 110,000 miles is beyond me. My lifetime average is 353 wh/mi and I do like to drive hard, but even when I'm being sensible it won't be under 300 wh/mi.

I think much of it has to do with climate. I bet you rarely have to run the heat or the pack heater. Both of those are significantly more crushing than AC use. Another factor is hills. While regen recovers downhill to some degree, it's lossy - somewhere around 20% losses. And of course wheels and driving contribute.
When I'm in the Sierras in the winter, I notice much higher consumption numbers than when I'm at the temperate coast.

I wonder if your car is a couple hundred pounds lighter too since you don’t have a glass roof or big wheels, maybe springs too...

260 Wh/mi at 1580 miles. S75D. I do most of my city driving in my Leaf, so most of those are highway miles.
Had it as low as 257, but lately I’ve had more hilly driving & some long drives in cool mornings by Northern California standards.

Currently a month in, drove just north of 5k miles and averaging 304Wh/miles (190Wh/KM)
For a bit I my conscience was yelling at me for not doing better, being the hypermiler I was with my gas cars, but then I've started deprogramming myself from that era and figured hey, if at the end of the day when driving back from my customer calls and all I have to do is come back home with a decent charge left, why should I not enjoy the drive, drive faster and get home quicker, and while we're at it, run the A/C or heat for comfort.
Really not much point in saving up on energy if you have the battery to call it a day. At least not with the prices per kW we have in Quebec.
Plus, it's gonna get cold here so the Wh/mile average is gonna get blown out the door regardless.
I'll get back to good ole hypermiling when it drops below freezing I guess. I don't seem to enjoy the perspective of that much anymore somehow.
