The new cleaner BS6 emission norms had a lot of going for it. It has greatly affected the automobile industry as well as the consumers. People have mixed emotions positive and negative about new emission norms as there are two sides to a coin. On one side some automobile manufacturers have discontinued their engines, some have developed new ones.
The best part about the norms which no other reason can match is, BS6 emission norms are 50%-60% more environment-friendly than BS4.
