If you drive it really canny and use the minimal electrics(i.e. no heaters,radio,turn down dash lights) you can get very good fuel consumption.
I went out the other night on a visit to the outlaws,which is a 34mile round trip and halfway out there,the low fuel warning came on.
Typically,there's no petrol stations on the route there,so when it came to go home,the display told me I had about 20miles worth of juice left and 17 miles to go!
I made it home,but I was impressed with the average mpg....44.9!!
I wish I had taken a pic of it....
