Fuel consumption Grand Vitara

Moin together, I recently bought a 2011 Grand Vitara 2.4L automatic, 4WD with 70k KM. Works very well so far, but I have now looked at the fuel consumption. I drive a lot of city, short distances with a lot of stop + go. Now not always kickdown but I’m already giving good gas. With 166 hp you have to move that also with the car really forward. I was surprised that it drives relatively sloppy. But when I calculated the consumption has me fas t hit the hit: 16,6 liters on 100 KM. Is that still in the frame or should I go with the box to the mechanic? It can hardly be that you can not drive 400 KM per tank with the Suzuki SUV.
