Car - Honda City (Sep 2012 model) - EMT
Mileage in City driving (no AC) = 16.6kmpl
Mileage in City driving (with AC) = 15.8kmpl
Mileage on Highways (with AC) = 19.1kmpl
These are figures i have been getting consistently over the last few months since i bought the car. All the figures are based on tankful method.
The figures in MID on an average have shown an error of 0.5kmpl
P.S: I have a very conservative style of driving and rarely race the car except on straight highway stretches
