Azc, I reset the computer at every charge and keep a log. The m/kwh reading does not correspond with what you would expect. Assuming a 22kwh battery and a range achieved of, say 75 miles, that should give a reading of 3.41 whereas I actually achieve 4.40 which would be correct for 17kw used. However it is an interesting readout.
Over the past 10 charges and a distance of 580 miles my average m/kwh works out at 4.75.
The figure is driving and temperature-dependent so will rise as summer approaches. My worst figure during the coldest period was 2.49, driving quite hard and with the heater on. In the past week I've had readings of 5.31 and 5.13 with normal driving and no heat on.
Years ago I used to keep a log of fuel consumption on my cars, so old habits die hard.
After charging the estimated range I find pretty accurate and I am pleased to see that at last it's crept up to 90, a sure sign of spring.
