Fuel economy improvement will also help the Indian industry, which is aiming to globalize, to become more competitive. The societal benefits in terms of fuel savings can be enormous. Also the ancillary benefits from the avoidance of green house gas emissions escalation will be significant. Without fuel economy
regulations there can be steady increase in size, weight, and power of vehicle fleet as has been noticed in other countries and also in India. While technology is advancing rapidly in other regions, there is huge potential for rapid diffusion of
improved technologies if regulatory standards are in place in India.
