u/660cc
I took a 223km drive in the country just outside of Tokyo. It was 60% highway, 30% winding mountain roads and 10% city. Weather conditions were favorable, but with some moderate wind on the highway that would impact efficiency a bit. I was driving as careful as I could to try to max out the number. Kei engine is 660cc 3 cylinder turbo with manual transmission. Totally stock.
Performance: 19.3 KM/L = 5.2 L/100KM = 45.4 US MPG
I'm pretty pleased with this!
