In city I'm getting 18-20 km/l with AC. Never took it out of city.
Overall its a good car. No maintenance required except oil change (0W/20 ZIC X9) and air filter. Once I changed ac filter as well. That's about it. No problem with AC as well.
1 issue I faced which was taken care of under warranty was noise in gear box when taking foot off the pedal. The noise was annoying. Rest was fine.
