New Delhi, The government has notified new corporate average fuel economy (CAFE-3) norms for automakers, removing a separate concession proposed for small petrol cars.<\/p>\n\n\n\n
The norms that were notified by the Ministry of Power will come into effect from April 2027 and remain in force until March 2032.<\/p>\n\n\n\n
However, the Centre had proposed a 3 grams per km concession for petrol cars weighing up to 909 kg in the previous year.<\/p>\n\n\n\n
The concession was opposed by several leading automakers.<\/p>\n\n\n\n
Moreover, the final rules do not provide a separate concession for cars below 909 kg.<\/p>\n\n\n\n
Instead, the government has changed the formula used to calculate a manufacturer’s fleet-wide carbon dioxide emissions target.<\/p>\n\n\n\n
The reference vehicle weight has been increased to 1,229 kg from 1,170 kg in the September 2025 draft. The final rules also use a lower annual weight adjustment.<\/p>\n\n\n\n
The changes provide relatively more relief to lighter vehicle fleets while making the targets stricter for heavier fleets.<\/p>\n\n\n\n
Under the final formula, a 909-kg car has an FY28 emissions target of about 82.8 grams of CO2 per km, compared with about 76 grams under the September 2025 draft. But for a 2,500-kg vehicle, the target is about 142.4 grams under the final formula, compared with about 151.4 grams under the earlier formula.<\/p>\n\n\n\n
In addition, the final CAFE-3 rules also retain incentives for cleaner vehicles through a super-credit mechanism.<\/p>\n\n\n\n
One battery electric vehicle will be counted as three vehicles for calculating a manufacturer’s fleet performance.<\/p>\n\n\n\n
The same 3x factor applies to range-extended electric vehicles.<\/p>\n\n\n\n
Plug-in hybrids and strong hybrids running on flex-fuel will get a 2.5x factor, while strong hybrids will get a 1.6x factor. Flex-fuel vehicles will get a 1.1x factor.<\/p>\n\n\n\n
Additionally, the rules also introduce a credit-debit system.<\/p>\n\n\n\n
Manufacturers that perform better than their emissions targets will earn credits, while those falling short will accumulate debits.<\/p>\n","protected":false},"excerpt":{"rendered":"
