Actual consumption of the UP also on highways and highways

Good evening, I would like to know from the UP drivers what you have with your UP with 60 hp or 75 hp for an actual consumption on highway and highway, if you do not necessarily want to be declared as an official traffic obstacle on the radio. My last test drive ended in disappointment of a small car, Opel Adam with 87 hp, my test consumption on a one-hour test drive, engine had already been warm, 20% highway, 60% highway, 20% city traffic and gucked to m testing was about 7 – 8 liters, I didn’t kick, except for once on the highway on the acceleration strip, acceleration as expected an absolute catastrophe, the Adam also has no turbo. So with the consumption I was more than disappointed.
