About 1.5 years back, we heard some news about the government of India working on the Fuel Efficiency standards for cars just like the Start ratings for electrical appliances by BEE (bureau of energy efficiency) in India. It took a lot of time to have materialized, and is yet to announced. The BEE has finally announced that system is under discussions and maybe announced very soon.
Ajay Mathur, director general, bureau of energy efficiency told that the govt. is working on deciding the standards which will represent the fuel efficiency of vehicles in Kilometers per litre of fuel. Different weight vehicles will be classified under different levels of fuel efficiency. The star system used for electrical appliances is also a possibility as its easy to understand by the buyers. The implementation of these new norms is likely to be made mandatory by 2015.
