Brother I have just recently received it and haven't bn able consume even the first tank as yet. On the in-dash dispay its showing around 12.5 to 12.8 km/l within city. Since I live in wah cantt which is a small cantt having so many trafic signals, I guess its almost the same as I used to get with my swift.
As far as the drive/ comfort/ pleasure etc are concerned that always depends on the car u have bn previously driving. In my case since I was using swift and therefore very obviously my feelings are that its awsome!!
