Lifetime Average Wh/mi

This site may earn commission on affiliate links.
Update: As of July 4th we're still trending down (with last 1000 miles at only 304 Wh/mi.) Totals now are: 16,699 miles 5,197.9 Wh 311 Wh/mi lifetime average Tires have 7/32 inch tread all around left on the factory 19" Goodyears as measured July 2 by Tesla service center. Northern CA.
Another update for our Model S lifetime energy use: 20,509 miles 6,337.6 Wh 309 Wh/mi I continue to get better and better average Wh/mi. This last 1000 miles was under 300 Wh/mi. Original factory tires still holding up OK as well, though I think I'll probably have to replace before 30000 miles.
 
Is anyone else steadily trending up? Over the past year my car has seen its W/mi go from ~331 to 339. Doesn't seem to correlate with climate as you would expect seasonal variations. Mine just seems to go up consistently. Car has been into service twice during this period so the alignment should be in check.

Nope, just the opposite.
 
Here are my Oct numbers:

Just hit 25,000 miles at 22.5 months!
 
@jerry 33 - your numbers are insanely good. Even going mostly downhill on So Cal freeways I never see those numbers. How fast do you drive on freeways?

Around 60 if there is no traffic, but if there is an alternative I don't take the freeways because state highways are more interesting and are generally traffic-free (I doubt the traffic-free part is true in California, but it's true in the prairie states.) Speed is still about 60 though. Around 50% of the miles are commuting miles and the rest are vacations and weekends. There isn't a great deal of difference between commuting Wh/mi and vacation Wh/mi although the nod goes to the commuting.
 
Ah, that makes sense. I always knew speed had the largest impact on efficiency but had no idea the effect was so large. Here in So Cal you'd practically get run over driving 60 on the freeways. No wonder my numbers are much higher.

People say that [practically get run over driving 60] here too, but I've never found it to be a problem. Of course, I keep to the right lane except to pass.
And yes, higher speed really takes a toll, which can be huge. As far as I can tell, the most important things are speed, tire pressures, not accelerating when going up hills, rocket launches, and hard braking. (The occasional rocket launch doesn't seem to hurt that much though :)
 
A day and 14.7 miles late (I forgot got take a pic last night, and I did a bit o' driving today). As usual, "A" is my near-lifetime and "B" is the past month. A little better energy usage this month, but at this point 10 kWh better = 1 kWh better for lifetime. ;-)

It's starting to get cold here; the last couple of days, I've had limited regen when I first got in the car. So I expect my numbers to get worse over the next few months.

The new phone + a daylight pic means an even better pic, of everything together.

Geez, you folks must all live on completely flat land!

My car has 14500mi on it and the lifetime Wh/mi is 358 and daily average is around 355. I go up and down 850-foot hills sometimes several times a day (going uphill right at 40mph speed limit gets the car up to 650-700 Wh/mi...)

I guess I need to move to Illinois or Missouri. But then I kinda like hills, and oceans, and views. :) Decisions, decisions....

Just wait, last winter I was averaging well over 400 Wh/mi. for a couple months! it's been nice to have temps above 40F to bring down the lifetime avg. but I'm afraid those days are coming to an end. Winter is coming.

As for oceans and views, you should come see the great lakes sometime... in the summer anyway. #thirdcoast

I'm in the Ozark Mountains, we're plenty hilly here. Much depends upon the distance you drive, speed and the driving behavior--anticipating stops, not doing crazy fast starts (at least not often), not tailgating, staying off of the friction brakes as much as possible, gliding down hills (as opposed to allowing regen to occur), etc. Moderating the use of climate control is a big factor as well.
