Lifetime Average Wh/mi

[ddenboer]

David, does that imply that you don't plugin overnight at home some of the time? So, you could be starting with a cold-soaked battery thus leading to weaker Wh/mile numbers? Or, is it just spirited driving up 101 and 280?

A lot of it is due to early morning school runs up 101 to Bailey, and then back down Monterey to Morgan Hill for drop off #2. My average for the 34 miles to work is usually 295-305. So basically too much stop and go on a cold battery for the school dropoffs before the long, constant speed drive to work.

And boy, does having the heat on make a difference in energy usage. For the ride home every day, we are usually at 280 Wh/mi unless it is very cold or wet out.

Makes sense now. For me, the situation is reversed. Within a half-mile from home, my son and I hit the highway and do a good 16 hwy miles before reaching his school just off 101. Then, it's hwy driving again to get to work. So, yeah, barely 4-5 out of 27 miles are on surface streets and most of those are after the battery's warmed up.

I'm at 450 Wh/mi...some combination of short trips, cold temps (cabin heat at 70), and stop-and-go urban traffic. Still a lot cheaper than buying gasoline.

 

[ddenboer]

Down to 359 Wh/mi now over 8500 miles.
Hoping with warmer mornings and less heating that it only improves. My last two charges have averaged 305, so I must also be getting better at driving more sane

 

[spatterso911]

2000 mi, 354 Wh/mi. so far, so good. What's the price of gas again?? Who cares!

 

[Ben W]

5000mi, 370 Wh/mi, P85, 21". Lots of test drives!

I really wish that in addition to "Ideal" and "Rated" readouts for miles remaining, the interface had a "Sport" mode option, calibrated to (say) 375 Wh/mi, which would more accurately reflect spirited driving than the 321 Wh/mi 'Rated' readout. Note that this is different from "Projected" range, which varies based on previous driving; a 'Sport' readout would always be on a fixed but more aggressive scale, and thus more predictable.

 

[ManuVince]

372mi, 161Wh/mi... I win !
Yeah ok with a Renault Twizy, doesn't count, don't have my model S yet :tongue:

 

[efusco]

~340 at around 4,700 miles now. Started the Month of Feb. with warm weather and was looking at 330 lifetime and under 320 for the month, but then the weather got bad and I got the itch to drive a bit harder and it crept back up a bit.

Here's a summary of the numbers above. A couple of people entered twice, so I used their more recent numbers. NA in the third table
means location not available.

1. Average unweighted Wh per mile = 377 with a standard deviation of 45.

2. Average Wh per mile weighted by miles driven = 367, just slightly less. (Likely the people with lots of miles are doing more highway miles.)

3. By State. There isn't enough data to draw firm conclusions, but the trend (warmer temperature states have better mileage) is pretty clear.

TX - 3000 miles - 326 avg.

 

[aaron.s]

All -

Just hit 3000 miles last night.

NY - 3000 miles - 366 Wh/mi

[Zextraterrestrial]

5600 mi and 391.4

 

[ckessel]

435 over 1600 miles. It's been chilly in Oregon in the 30s, but no where near Minnesota chilly. Not sure why my energy usage is so high.

Still at 426 over 3000 miles. The whether has been pretty mild overall, especially the last couple weeks (and my usage didn't really change), so it must be all the hills in Portland rather than the temperature.

 

[mnx]

From February 14-28

1121 km's
393.6 kWh (from the wall)

= 351Wh/km

or 561.6 Wh/mile

The car is reporting 1421km's now and 244Wh/km or 390Wh/mile.

Notes:

Mine's an 85kWh Performance
I have 19" lightweight wheels (23.3lbs) with low rolling resistance Michelin Pilot Alpin PA3 Winter Tires.

 

[Cliff Hannel]

I'm at 345 Wh/mi with 4100 miles since Dec 19. A lot of highway at 70-ish mph. Live in SoCal, so weather is mild - cold weather seems to increase consumption by 10-15%. I have charts/numbers/spreadsheet at EVTripPlanner

From my experiece, these numbers are pretty close in mild weather:

 

[Jeff Miller]

Average: 375
Standard Dev: 43

I haven't weighed in with an update since I started the thread, so it's time:

Currently averaging 318Wh/mi, settling down toward what looks like typical usage of around 316. The car now has more than 3000 miles on it, and we're planning a trip down to the San Diego area this weekend. It will be interesting to see how she fares on the longer haul drive.

You're doing quite well for 3000 miles. Other than warm weather any tips, or conclusions?

 

[Banahogg]

It may be worth separating the averages for the different battery sizes.

I'm at 307Wh/mi average over 1205 miles.

 

[digitaltim]

Just crossed 10k and average is 375 Wh/mile.
