The new standard that require the passenger all cars (hatchbacks, sedans, SUVs etc.) to meet an average fuel efficiency of 18.2kmpl have been created by the Bureau of Energy Efficiency. The enforcement of the new laws would be applicable on all cars from April 2017. The new standards would require the manufacturer to maintain an average fuel efficiency of its cars at 18.2kmpl.
In case the mileage of a particular model of car is below the require figure, the manufacturer would require to exceed the overall average of their product portfolio than 18.2kmpl. It is likely that the target figure for the manufacturers would be increased to 22kmpl by the year 2022.
A different standard that would require the commercial vehicles like buses and trucks to meet the average figures would also be in place soon. The new standards, when in place, would make India at par with European Union which has enforcement to keep CO2 emissions in check. The standards require that the car should emit less than 130g/km of CO2 which increases the effective efficiency of petrol cars to 17.85kmpl and diesel cars to 20.4kmpl.
Projection for 2021 is to reduce the emission to 99g/km and in effect to aim the average of petrol cars and diesel cars at 24.39kmpl and 27.7kmpl respectively.
