I Beat EPA's 2.9 Miles/KWh : Report Your Monthly Mileage

I agree that my mileage will drop with running the a/c. My past numbers have included only rare use of climate control.

I have only been driving my 2011 Nissan Leaf for a little over 2 months and I seem to have settled at 4.3 miles/Kw. I drive mostly 55 & 45mph to work and back each weekday which is about 56 miles round trip. Locally my electricity costs 13.4 cents/Kw.

If you can specify if you drive in 'D' or 'ECO' mode, that will help.

May mileage:

Wall-to-wheels: 4.36 miles/kWh

Dash: 5.1 miles/kWh

Charging efficiency at 240 V, 16 A: ~85% (This figure includes a number of charges to 100%, which are less efficient than charges to 80% or less.)

As the weather warms my mileage continues to increase. May numbers were helped by two 100+ mile trips on single charges, which involved some hypermiling, and little or no heater or AC use.

Notes: No preheating used, so charging efficiency can be calculated, although the dash mileage numbers are too coarse for precision. Driving temperatures were mostly 60s and 70s. Battery temps of five bars most of the time with six bars seen at times, often after climbing hills. Elevation range: 8,000 feet to 5400 feet. All driving includes steep hills. No multi-lane highway driving at all. Some of the driving is on dirt roads.

Dec/2011 Platinum 574 5.2 miles/kWh

A/C usage and more interstate driving cut my m/kWh to below 5 for the first time.

And I got over 5 m/kWh on my CW monthly report for the first time.

My 540 mile drive (on an L2 trip, the slower you drive, the faster you'll get there) to the San Francisco bay area and back, helped to raise the average.

I also had my greatest miles per single charge on 5/31, 105.8 miles (with about a mile each, of ascent and descent!) by my odometer, reported by CW as 103.2 miles at 5.9 m/kWh.

CW continues to under-report miles driven by about 2.5%, so I believe all the m/kWh numbers below should be adjusted upward by the same 2.5%, for greatest accuracy.

Month and Year Grade Rank Energy Economy
*Jun/2011 Gold 695 5.7 miles/kWh
*Jul/2011 Gold 1651 5.3 miles/kWh

Sep/2011 Silver 3457 4.5 miles/kWh

May/2012 Gold 1978 5.1 miles/kWh

*Prior to CW update. Disregard, as correction factor unknown.

PS-

I just noticed that my May 2011 reports have been dropped, as the "rankings" only track the previous 12 months.

So if you wish to keep track long term, you should save this data elsewhere.

For May-2012 Carwings shows 4.8 Miles/kWh. I stopped logging daily trips since CarWings works now.

As expected with warming weather, I'm getting better m/kWh.

At 17K MILES - we've managed to come back up to 5miles/kWh at the wall - after dropping to 4.9 last winter ~ as 'she who must be obeyed' drove around more in it too.

Got 4.9 kWh in June, same as in June 2011 !




Here is the comparison to avg. temperature.

June mileage:

Wall-to-wheels: 4.48 miles/kWh

Dash: 4.9 miles/kWh

Charging efficiency at 240 V, 16 A: ~91% (This high figure may be due to only one 100% charge; 90% or less is adequate for this time of the year for long trips and 50% to 60% when shorter trips are planned. I find it fairly simple to charge in half hour blocks depending on how many fuel bars I think I will need over the next day or two; I just adjust one of my timers as needed.)

My miles/kWh was lower than in May (5.1 miles/kWh) but June driving included more vertical/mile and fewer more efficient longer trips. June had two trips over Red Mountain Pass, 11,018 feet and had some AC use, which was not the case in May. Also, May was exceptional because of two 100+ mile trips on single charges that involved significant hypermiling.

Notes: No preheating used, so charging efficiency can be calculated, although the dash mileage numbers are too coarse for precision. Driving temperatures were mostly 70s and 80s. Battery temps of six bars most of the time and nothing but six bars the last two weeks; June is usually the sunniest, hottest month here. Elevation range: 11,000 feet to 5750 feet. All driving includes steep hills. No multi-lane highway driving at all. Some of the driving is on dirt roads.

I see on carwings that the "world champion" of miles KWH in the Leaf is averaging 56.6 miles KWH! How is this possible? Maybe he lives on top of a big hill, has the car towed to the top every day, and coasts down to the bottom? :? :? :? :? :?

Find a long gentle descent. Power cycle the car, accept carwings disclaimer. Drive to bottom. Power cycle car, decline carwings disclaimer, return to top of hill, power cycle car....

56.6 miles/kWh * 21 kWh usable = range 1188.6 miles!

AHA! :lol: Seems like a lot of effort, just to be the champion. That guy's gotta get a life, me thinks.

July mileage:

Wall-to-wheels: 4.41 miles/kWh

Dash: 5.0 miles/kWh

Charging efficiency at 240 V, 16 A: ~88% (This high figure may be due to no 100% charges; 90% or less is adequate for this time of the year for long trips and 50% to 60% when shorter trips are planned. I find it fairly simple to charge in half hour blocks depending on how many fuel bars I think I will need over the next day or two; I just adjust one of my timers as needed.)

Notes: No preheating used, so charging efficiency can be calculated, although the dash mileage numbers are too coarse for precision. Driving temperatures were mostly 70s and 80s with some 60s. Battery temps of five bars most of the time with six bars on warmer days or right after charging; July is usually cooler than June here, once the "monsoon season" begins and it came right on schedule. Elevation range: 8,000 feet to 5750 feet. All driving includes steep hills. No multi-lane highway driving at all. Some of the driving is on dirt roads.

Actually approximately 88%-90% is what u should be getting

4.9 m/kWh on dash for July.

5.2 miles per kwh for july per carwings for 1024.4 miles

i dont think i posted July figures. now, i can only say i got 5.1 from the Car. i used a LOT of public charging (Quick Charge gone wild! ) in July so i tossed my "wall" numbers since not all of them provide data on charge received.

but the real reason i wanted to post this is a large # of things

gas prices dropped from $4.18 to $3.20 then bumped to $3.39

before posting July, my 3 month average Apr-Jun driving

Prius 1314 miles @ $112 LEAF 1140 miles @ $24 total average; 2454 @ $136

for July; Prius 818 miles @ $61 LEAF; 1587 miles @ $28. total 2400 @ $89

so basically saved about $50 (real savings was $39.60) from excessive use of free charging.

if it had been May when gas was $4.18 then savings would have been about $60.

savings from driving a LEAF over a Prius; $80
savings from driving a LEAF over a 30 mpg car; $151.31
