India Revises Car Emission Rules, Offers Relief to Small Cars
India is changing the rules about how fuel-efficient cars need to be.
The government wants cars to use less fuel to help the environment.
They are giving small cars a break, letting them look better on paper.
They also give incentives for cars that use cleaner fuels like ethanol.
Car companies like Maruti Suzuki will benefit because they make a lot of small cars.
