The best thing, and I guess all will agree about Honda City new models (2009 and onwards) is is fuel Efficiency. I heard about it until I bought one couple of months Ago
The car has done 3000kms and is giving me
18-20 Km/Ltr On highways
12.5-14 km/Ltr with in City
For all who have doubts about the accuracy of the Fuel Display, I drove from Rawalpini to Peshawar on 10 ltrs of fuel !
According to my personal Experience the Best range on a straight road highway is
Rpm - 3100-3200
Just accelerate slowly and see the wonders on fuel Display
