Thats the difference of the manual and auto car. I drive a manual 1.3 L yaris, I constantly get 600-700 km per tank, that is average of 6.5L/100KM. Even in summer with 90% AC use, the fuel consumption also returns under 7L/100km, and no matter how deep I kick the pedal the fuel won't affect much. The worst fuel consumption I got is 7.5L/100KM in summer and heave traffic jam, the best I got is 5.5L/100km on highway. I drove a 1.3L auto yaris before on 90% highway around 1300KM and 10% city suburb. I was shocked it returned 7-8 L/100KM.
