@ Ami.
I agree that auto journalist do their job well, and they will keep doing it. But the mileage extracted by them will differ, all mags will never come with same mileage. As mileage depends on lot many factors.
As mentioned earlier these mileage is conducted by Govt. Agencies, in a standard test condition. This test is conducted in a lab using a standard fuel. Load of 2 persons with AC off. Time is for 20 mins with fixed gear and speed changes.
The mileage in practical conditions will vary with traffic, time, road conditions, driving style, fuel type used, tyre pressure, maintainance, weight, etc.
This test is useful because this same test is conducted for all cars by the mentioned certified agencies. So comparing different vehicles fuel effeciency is easy and fair.
Not only in India, such type of tests are conducted in overseas also. In USA - Agency EPA ( Environmental Protection Agency ) and in Europe - Agency ECE ( United Nations Economic Commission of Europe ).
This initiative is taken into consideration that it will help both the buyer and seller for easy and fair process, when it comes to fuel economy part.
And about mileage, i have an example to give. Though the home appliances remains same, why the electricity bill differs. Because of our usage pattern. We never blame the electricity board for the fluctuation in our bills and comparing to others.
I am not offending you or defending myself, i just wanted to create an awareness among all to help them making their purchase process easy and effecient. And also such awareness about fuel effeciency may help all in one or the other way.
Life is all about living, not just existing... So don't just exist.. LIVE.........
