India's Fuel Efficiency Rules Explained: Goals and Debate
India is making new rules to make cars and trucks use less fuel.
This is good for the environment.
The government wants to use less imported fuel.
They are working on a graph that determines how efficient cars must be.
Different rules apply to cars and trucks, which are designed to push automakers to make more fuel-efficient vehicles.
The government is also pushing for the use of E20 petrol.
These new regulations have benefits for the country, like less air pollution.
But the car companies are worried about the high cost.
The government is trying to find a good balance.
India's fuel efficiency rules aim to reduce vehicle emissions.
The Corporate Average Fuel Efficiency (Cafe) framework is tightened every five years.
Discussions are ongoing for the third iteration of Cafe rules, to be implemented in 2027.
E20 petrol is now mandatory in India, blended with 20% ethanol.
