3.9 liter gasoline (europlus) for 100 km with a Toyota Prius

Well, not exactly. At the end, when I was able to take the picture, the fuel consumption was 4 liters per 100 km. But still, it's not a Diesel, it's unleaded gasoline and it's a car of 4.5 m lenght with 5 seats and all the comfort we are used today. So, not bad at all. The display is shown the German language, but the bar chart is understandable anyway. With a modern hybrid car you can stay substantially below 5 liters and most of the time below 4 liters even. The 80 kms included city traffic, highway and other streets, nothing artificial. Average speed probably something like 70 km/h. I must admit that I tried really to safe fuel, for example by not using the air condition (it wasn't hot anyway) and by not rushing up the hill. The good thing about the Prius is that it motivates the driver to save energy. But it takes experience also and it's not well enough explained in the manual. For example, braking isn't braking all the times, it depends on how much you step your foot on the pedal. I actually think Toyota should do a campaign with pictures like this (ideally with a number 2 or 3 for the consumption), this could be impressive.
