CAFE 3 Draft Proposes Stricter Car Mileage Targets
The Bureau of Energy Efficiency in India has proposed new rules called CAFE-III that aim to make cars more fuel-efficient and produce less pollution.
The new rules suggest that by 2027, cars should emit no more than 91.7 grams of carbon per kilometre.
Currently, carmakers test their vehicles in a lab, but the new rules propose using a testing method called WLTP, which is used globally and gives more accurate results.
This change is important because it will affect what kinds of cars are available in the future.
Carmakers might start making more hybrid or electric cars, or they might improve their petrol and diesel engines to meet the new standards.
The rules will be in effect from 2027 to 2032.
The Bureau of Energy Efficiency has proposed stricter carbon targets of 91.7 grams per kilometre for cars.
The new CAFE-III norms will apply from FY2027-28 to FY2031-32.
The current MIDC lab test will be replaced with the globally used WLTP cycle.
The WLTP cycle measures fuel consumption closer to real-world conditions.
Carmakers may respond by pushing more hybrids and EVs or improving petrol and diesel engines.
