After BS3 in 2010, it took the Indian government 7 years to shift to BS4. Due to the huge gap, the government decided to skip a step in between (BS5).

Shifting to BS6 emission was unstoppable.

After the BS6 norms rollout definitely the BS4 diesel vehicles will get affected.

Although there are changes in BS6 petrol fuel from BS4 it’ll have no effect on vehicles running on BS4 fuel.
Even though the registration of new BS4 vehicles will stop after the 1st of April but they’ll still run on the Indian roads without any problem. Though BS4 cars will keep on emitting the same amount of exhaust gasses.
