India's regulators have revised a draft of upcoming fuel-efficiency rules to eliminate a previously proposed concession for lighter petrol vehicles, according to the latest government document. The change follows objections from automakers, including Tata Motors and Mahindra & Mahindra, and tightens requirements across the board.
The circulating text shows the September draft included a carve-out for petrol cars with a curb weight of 909 kg (2,004 lb) or less. Market observers had widely interpreted that provision as providing an advantage to the maker that currently controls about 95% of the small-car market in India.
In the most recent 41-page draft, the Power Ministry has removed the small-car exemption and amended multiple parameters to reduce opportunities for manufacturers to be over-compensated on account of vehicle weight. The stated objective of the revisions is to foster a more level competitive environment between producers of lighter and heavier vehicle fleets and to drive measurable improvements in real-world efficiency.
The document describes the updated standards as introducing "a substantially steeper reduction pathway" for emissions. That language signals tighter timelines or targets for lowering fleet emissions, according to the draft text.
Removed from the rules, the small-car carve-out had been perceived by critics as creating an uneven playing field. With that provision now gone, the revised rules are constructed to apply more uniformly, increasing regulatory pressure on all manufacturers to expand sales of electric and hybrid models.
Automakers named in the document had previously voiced objections to the special treatment for the lightest petrol cars. The revised draft addresses those concerns by limiting weight-based adjustments and strengthening other technical parameters, reflecting a policy shift toward stricter, broadly applicable efficiency requirements.
Context and next steps
The government document is a draft and presents the revised framework in its current form. It outlines changes intended to reduce emissions and to prevent disproportionate advantages tied to vehicle weight. The draft does not detail enforcement mechanisms or implementation timelines in the passages quoted here.
