Why does the 2018 Sharan 2.0T 380 TSI consume 11.5 liters per 100 km? My Tiguan L 2.0T with low power version only consumes 7.3 liters per 100 km. I take good care of my car and accelerate gently, so why is the Sharan's fuel consumption so high? The major maintenance for the Sharan was just completed!

How's the fuel consumption of the Sharan? Is the combined fuel consumption around 10 liters? Can it maintain around 9 liters on the highway?
