@siyyam It's normal. The mileage will improve after the break-in period (Although Honda Atlas claims their cars are already pre-run). Just drive the car carefully for the first 1000 kms (I would recommend 5000 kms). I bought my City in 2009 and also had cited the same issues in a post on this forum some six or seven years back. It used to give 8-10 kpl at first and the pick up was a tad heavy as well which gradually improved over time. Now, I'm managing 13-14 in city and 15-17 on highway. If mileage is your concern, stick to OEM specified tyres, and always use genuine Honda oil filter, Air filter and Engine oil. Use Genuine Honda Oil Synthetic 5W 30 oil. It's the same as Total Quartz 9000. Also be sure to avoid driving during peak hours when traffic jam probability is at its highest or you will not be able to achieve good mileage. 9-12 is pretty good for a 3 days old car. Enjoy your ride, brother.
