I guess they were driving up a mountain all the while during this test ? I would have to drive like an ICE maniac with full heat ON on a cold winter night, for me to get that efficiency.
Keep in mind that the EPA estimate is from the wall. Multiply your dash number by 85% to get closer to your actual consumption numbers. EPA 2.9 mi/kWh is about 3.4 mi/kWh on the dash.mkjayakumar said:EPA estimate is only 2.9 kWh ?? WTF ?

dgpcolorado said:April mileage:
Wall-to-wheels: 4.0 miles/kWh
Dash: 4.6 miles/kWh
Charging efficiency at 240 V, 16 A: ~84% (included some charges to 100%, which are less efficient than charging to 80% or less)
As the weather warms, and April was unseasonably warm and dry here, my miles/kWh continues to increase. I'm curious as to what sort of numbers I will get in summer. I'll never get the numbers that the mild-weather flatlanders get, but I think I might get as high as 5.0 on the dash...
I did take a look at the Carwings report yesterday for the first time (had some trouble finding it). It was just gibberish. Whether that is because I don't always push the "yes" button or because there is no cell reception in my garage I don't know. But the information was not accurate or useful.edatoakrun said:If you take a look at your CW report for April, you might find that it matches your “dash” (behind the wheel-right?) average.
If you also recorded a monthly m/kWh report from the nav screen, it might be more accurate, as both the dash and CW may be under-reporting m/kWh by the same 2.5%. (due to the same odometer error?)

I have noticed that the console mileage meter runs about 0.1 miles higher than the dash one, when I run them simultaneously at the beginning of the month. That's about the 2.5% you mentioned. Others have reported the same.edatoakrun said:Cell reception shouldn't be a problem. Mine is marginal at home, but it updates and recovers all CW driving reports, whenever I drive into Cell range.
But yes, CW will only function if you "accept" it.
If you do, you should get the same consistency and accuracy as shown in EdmondLeaf's post of daily use above.
Just check your car odometer and CW against another source (like google maps) for miles, and correct as necessary, for the greatest accuracy.
Most have reported the same experience I have had, a 2.5% constant under-report for CW (on new stock tires) and that the dash odometer is very close to accurate.
dgpcolorado said:...I doubt that Google maps could handle the complex terrain where I live with accuracy. But it isn't really necessary anyway since the car odometer, whether precisely accurate or not, is consistent, except over long time periods due to tire wear. Carwings isn't necessary to get mileage data, I just log the car odometer several times a week. That's a lot easier than remembering to push the "yes" button ten times a day.
