trip A
trip B
MPG on photo trip A total average after topping tank to full, there lower average MPG because first 4 trips needed to use climate control with temp set to 25 degree C (outside temp 29 degree C) and this trips shorter than 10 mile.
MPG on photo trip B in town with max speed 25 MPH without A/C.
Key to fuel economy - right speed (in town if there every 500m runabout or trafic light it`s 25 mph) and avoid short trips, best result on trips 10 miles or more, coast (glide) as much as possible, if acceptable drive up the hill at a slightly lower speed, so we will use less energy from the battery and the generator will turn on much later, smart usage of A/C or climate control and when acceptable use only fan with choice of air from outside.
if you want call me captain snail, I understand that almost no one will drive a car like that, but nevertheless here it is the result - consumption of only 104.4 miles per gallon on fairly even road, all trips were started with the battery charged to 3-4 bars (specially I didn’t charge the battery because it worsens the average consumption per tank) when charging while standing still, about 2 kilowatts out of 5 that the internal combustion engine consumes are lost to heat.
