Lifetime Average Wh/mi

[brianman]

For those keeping track of the stats...

My 426 has dropped to 415. Weather, not tamer driving. Definitely not tamer driving. I need to get used to softer music or something.

cattledog 354 Wh/m 3000 m TX 85KWh 19" wheels

 

[youlikeadajuice]

After 900 miles, I'm averaging 340 Wh/m. The weather today was 10-15 degrees warmer than it has been, and it really showed on my commute into NYC. Can't wait for even better efficiency as it warms up!

 

[FalconNinetyD]

If we're officially keeping track, I'm down to 359 w/mile after 3000 miles.

CA, P85, 21"

 

[jkirkebo]

For comparison my Leaf was at 290Wh/mile for the year 2012, according to CarWings. This includes quite a lot of heater usage in the winter.

 

[Cliff Hannel]

@Jeff - do you have the data compiled in a spreadsheet or database file that I could get? I'm working on a "Route Energy Estimator" as part of EVTripPlanner and having this type of data would be really useful.

My data is above, but I think I didn't post that I currently have 19" wheels (21" still on due bill).

 

[Beavis]

I was having fun when I first got the car:
343 wpm, 2765 mi., CO, 85, 21's

It's been warmer the last 2 months and my numbers are better:
333 wpm, 1759 mi.

Cliff, attached is the data I have so far in an excel spreadsheet (for some reason the site wouldn't let me upload a
text .csv file or an openoffice .ods file). Let me know if you can read it.

When I didn't know someone's configuration from this thread, I checked their posts on other threads to see if they posted it elsewhere.
So I must have seen your config as 21" on one of these posts. Some people like digitaltim have 21" wheels but go to 19" wheels in the winter.
In these cases, I just leave the wheel variable at NA since we don't know what the energy consumption or mileage was when the different type of wheels were on.

If other people see errors in their numbers or have updates on their data, just post here. I'll try to update the stats every so often. I expect that as the weather warms up, the fleet average wh/mile will do down and then start to rise again next winter.

 

[gg_got_a_tesla]

I expect that as the weather warms up, the fleet average wh/mile will do down and then start to rise again next winter.

I'm experiencing this already. I got to 3,000 miles at 322 Wh/mile but, when using the AC in 65+ degree temps, I've struggled to get it under 340 Wh/mile with normal driving.

[Zythryn]

Jeff, thanks for doing this, it is incredibly valuable information!

Just an update:

Zythryn 384 Watts per mile over 7100 miles in MN. 19" wheels, 85kW battery.

Looking forward to the warmer weather, efficiency is already getting better.

 

[StephRob]

This is the most interesting and useful thread on the forum. Keep it up! And if you haven't posted your data, do so! The more data the better! And it makes me wonder if there's someone inside Tesla who captures and analyzes this data for all the Model S out there. Now that would be fascinating to see.

 

[Cliff Hannel]

Average Wh/mi with stats

Jeff - thanks for posting. I have attached Excel with pivot tables showing averages for state/wheel/etc (so no need to do manually). Not enough data yet to draw conclusions - but Tesla has plenty more. Hope they do something useful (for us) with it...like enhance energy app to take weather and destination (from nav) into account.

[Jeff Miller]

Thanks Cliff. I coded the calcs up in R (a statistical software language) so it's pretty automated for me as well - I just add any new data as it comes in. I agree that we need more data in order to make firm conclusions about long term energy consumption as a function of the various things that affect it. More data from different climate regions (17 of the 46 observations we have are from California, very sparse coverage elsewhere), different seasons (no spring or summer data yet obviously), more data from the 60 and the yet to be released 40s, etc. Tesla may have all this info, but doubt if they will make available. There is also a question as you indicate in your spreadsheet whether the observed (so far) higher wh/mile for the 85s relative to the 60s and the 21s relative to the 19 is entirely due to the different characteristics of the car (higher battery weight for the 85s and more friction for the 21s) or if there is also an element of driving style (people who opt for the 85s and 21s may also like, on average, to drive faster). In a way, it doesn't matter what the source of the difference is, as long as it's real. That is, if 85/21 owners really do drive more aggressively than 60/19 owners do, and if you are going to buy a model S, then statistically (assuming the effect is real) you will also tend to share (in a population average sense) the driving style of other owners who buy Ss with the same options. In any event, I think it's interesting for us owners to keep track of fleet energy use, and also of charging losses/vampire drains that people are recording on other threads.

 

[FalconNinetyD]

I'm experiencing this already. I got to 3,000 miles at 322 Wh/mile but, when using the AC in 65+ degree temps, I've struggled to get it under 340 Wh/mile with normal driving.

AC in ~65 degree weather? Even with the greenhouse effect of the car, I don't have the need to use AC until outside temps reach 75 or so. Turning the climate down to LO and raising the fan speed up to 5-6 seems to be enough to keep the interior pleasant...

 

[Nickjhowe]

Florida, 21", P85 1600 miles, 340 Wh/m since 1/3/13

 

[rcc]

As I suspected would happen, now that overnight/morning temperatures are going up, my watts/mile is getting better.

My average over ~3500 miles has dropped to about 365 watts/mile (down from 375). Over the past ~1500 miles, I'm seeing 355 watts/mile. And I see 315-335 driving on warmer days in the middle of the day.

 

[gregincal]

I have an average of 330 wh/mile for my first 500 miles. 85 kWh, 19" wheels, CA.

 

[ChadS]

361 wh/mile over the last 6,000 miles (trip meter got reset somehow). 85kWh standard, 19" wheels with Pirelli winter tires, near Seattle WA.
