I have a 2011 Altis auto, done 69,000 kms and when I drive it gives 10-10.5 km/L in city, and when my brother drives it gives 8-8.5 km/L. I generally keep car in 2,000 rpm range and brother drives in 3,000 rpm range. On Khi-Isb trips it has consistently given 14km/L, but if I keep below 100km/h it gives 16km/L.
lets see in couple of years and approx 120k kms on odo how it performs.
