Poor fuel economy on petrol vehicle

Poor pertol aveage in urban area in Creta petrol S model. Riding it in Delhi. It was purchased from Hans Hyundai Moti Nagar. Very good experience. Have driven 400 km till now. The claim was between 13-17 Km per km. Did not imagine it can be so bad. Let us see if improves after service, but it cannt improve so much I feel. I cann't understand if it can be car of the year and yet mileage is so bad. If we are so much concerned about carbon emission, mileage should be a primary parameter for selecting car of the year.

I have a Santro 13 years appx and is still running very well. Still Milege in it is about 12-13 kmpl in Santro.

Hyundai services are good. That is what attracted me to this.

Govt is discouraging diesel & hence I did not take it. So far disappointment. I will not be able to ride it regularly unless  Hyundai can do some miracle.
