What is Fuel Economy? OR Simply, How much it gives?

Fuel economy: The Myth and The Reality

Fuel economy is one of the most sensitive issues and an important factor while buying an automobile; be it a motorcycle, a car or even a truck or bus. For most automotive buyers across the world, it affects the running expenses of the vehicle. In simple terms, fuel economy is the number of kilometers per liter or gallon worth of fuel.



A car’s mileage or average is the number of kilometers or miles it travels on a liter or a gallon of fuel as the case may be. However, in the real world scenario, the fuel economy of a vehicle is calculated based on the number of kilometers traveled on a full tank of fuel. For e.g. 15.0 Km/L for a car or 60 Km/L for a bike on an average.

But, in some European countries; this is reversed. There, the fuel economy is measured in terms of the number of liters of fuel consumed per 100 kilometers for e.g. 8 liters/100 Km in case of a car or 2.5L/100 Km in case of a motorcycle on an average.

Who certifies the Fuel Economy data?

Every country has its own standards and testing agency to test fuel economy. In America, the United States Environment Protection Agency (US-EPA) certifies this by conducting tests which measure the total volume of carbon captured from the vehicle’s exhaust. All vehicle manufacturers are required by law to display the fuel economy ratings on the cars sold in the USA. In the US, fuel economy is measured in ‘Miles per Gallon’ or mpg.

In India, Automotive Research Association of India (ARAI) conducts fuel economy tests based on Indian Driving Cycle (IDC). Indian Driving Cycle (IDC) is a laboratory test conducted on a rolling road which simulates a typical Indian driving environment over 10 kilometers. However, in the real world driving conditions, you can expect to get -10% to -20% (less) of the ARAI certified values as claimed by manufacturers.
