Having done 30,000 klm or 18,641 miles in a year in my Toyota Prius i am glad it gets good fuel economy as fuel is rather expensive here at around $1,60 a litre. This secondhand car that i bought a year ago is realy paying it's way in fuel savings:) exactly why i bought it.
This photo of the average economy for the last 950 klm shows 3.9 l/100klm or 72.43 British mpg or 60.31 U.S. mpg
My 4WD would use around 9.8l/100klm.
Hope your day/night is going well.
