Indian automobile manufacturers will now have to follow strict fuel efficiency standards. The government is likely to extend the deadline for implementing the Corporate Average Fuel Efficiency (CAFE-III) standard. Speaking to news agency PTI, a senior government official said that these new rules will be effective from April 1, 2027.
Heavy Industries Ministry Secretary Sunil Barthwal said on Monday that the government is in constant touch with the stakeholders of the auto industry. He said that the opinion of the industry is being taken on CAFE-III standard, due to which the decision is being taken to extend the deadline from the originally scheduled date. Earlier there was a plan to implement it soon, but now it is proposed to be implemented from 1 April 2027 to 31 March 2032. This period will be of five years, in which strict standards will be gradually implemented.
What is CAFE-III Standard?
CAFE-III standards control vehicles' fleet-economy fuel efficiency and carbon dioxide (CO₂) emissions. Under these, vehicle manufacturers will have to limit the average CO₂ emissions of their entire fleet to about 91.7 grams per kilometer, which is much stricter than the current level. These rules will be based on modern testing cycles like the Globally Harmonized Light Vehicle Test Procedure (WLTP), which better reflects actual driving conditions.
The objective of these standards is to promote environmental protection, fuel saving and electric vehicles (EVs) and hybrid technologies. EVs are likely to get special credits in these rules, which will help companies achieve the target.
differences between companies
Disagreements persist regarding these rules in the auto industry. Small car manufacturing companies are demanding discounts on the basis of weight and affordability. Their argument is that small cars already have low emissions and if they are given relief from strict standards, then cars will remain affordable for common consumers. Companies like Maruti Suzuki and Toyota Kirloskar are supporting an additional 3 gram CO₂ per km relaxation for small cars (ie those weighing less than 909 kg, engines up to 1200cc and length up to 4 metres).
On the other hand, big automakers like Tata Motors, Mahindra, Hyundai and Kia are opposing such individual discounts. He says that this will compromise safety standards and increase inequality in the industry. They are in favor of a uniform standard, so that all companies adopt equally clean and safe technology.
A middle path will be found!
The government has called a high-level meeting to build consensus on this issue. This will include secretaries of the ministries of power, heavy industries and road transport and highways. There will be a detailed discussion on the draft rules of CAFE-III in the meeting and the final decision will be taken keeping in mind the opinions of all the parties.
Will cars become expensive?
The implementation of CAFE-III will have a huge impact on the auto industry. Companies will have to increase investment in engine design, weight reduction, hybrid systems and electric vehicles. This may increase the prices of cars slightly, but in the long run, both consumers and the environment will benefit from fuel savings and less pollution.
