This is the fuel efficiency graph of the 2010 Mira Custom in use by our family. Fuel efficiency was computed not from the number displayed on the speedometer, it was calculated after each fill-up which involved driving the car till it was close to empty and then filling up the tank completely.
This car is mainly used for driving kids to and from school. It has a CVT transmission which is more efficient than a 4 speed automatic On average, the car is driven between 900-1000km a month. Best fuel efficiency is achieved in winter months, Nov-Feb because the AC is not used during these months. With AC, fuel consumption increases considerably. The car is driven by two people mostly, I drive it in the morning to drop kids to school and my wife drives it in the afternoon to pick them up. The wife drives with a slightly heavier foot so she gets less MPG than when I am driving it. Figures for three months, June, July and August are missing because of summer vacations. The graph might not be 100% correct but it is fairly close to a real world fuel efficiency test.
*Update- Graph updated after correcting figures for Jan & Feb 2013
