New Regulation for Accurate Fuel Measurement
The Indian government has proposed a new regulation requiring mandatory testing of vehicle mileage with the air-conditioning (AC) systems both switched on and off. This policy from the road transport ministry will come into effect on October 1, 2026, and is applicable to all passenger cars, including internal combustion engine (ICE) vehicles and electric vehicles (EVs) manufactured or imported in India.
Officials have stated that this regulation is intended to provide more realistic and reliable fuel efficiency figures, as AC usage significantly impacts both mileage and energy consumption during real-world driving.
Importance of the New Regulation
Currently, vehicle manufacturers in India declare fuel efficiency ratings based solely on tests conducted without the AC running. This practice has been justified by automakers using European testing standards, which do not account for the AC’s operational impact on fuel consumption. However, this has led to discrepancies between advertised mileage and real-world performance, affecting consumers’ purchasing decisions.
By introducing this requirement, the government aims to enhance transparency, allowing potential buyers to make informed choices based on realistic mileage figures. The revised regulations will require manufacturers to include mileage data with and without AC usage in vehicle user manuals and on their websites.
Details of the Regulation
Testing Standards and Procedures
The draft notification specifies that from October 1, 2026, all vehicles categorized under M1, which includes cars, must undergo fuel consumption tests that reflect AC operation. This will adhere to the revised AIS-213 standard, meant to capture additional fuel consumption attributed to the AC’s load. Officials stated that this standard is crucial in assessing how AC usage impacts emissions as well.
This comprehensive testing approach will ensure that emissions and fuel consumption levels are accurately represented, providing data that aligns more closely with actual driving conditions. As stated by a ministry official, “Testing under real-world conditions allows consumers to better understand the actual performance of their vehicles.”
Moving Toward Transparency
In the past, consumers often faced surprises at the fuel pump due to the significant difference between claimed and actual mileage. With the new requirement, manufacturers will be compelled to provide dual fuel-efficiency figures, thus allowing buyers to compare performance in varied conditions.
According to industry experts, this regulation not only empowers consumers but also promotes accountability among manufacturers. It is expected to result in more energy-efficient vehicle designs that consider the practical use of air conditioning.
Reactions to the Regulation
The automotive industry has shown mixed reactions to the proposed changes. While many support the move towards transparency, some manufacturers have expressed concerns about potential increases in compliance costs and the need for additional testing processes.
An official from a leading automotive manufacturer commented, “Aligning our testing with real-world conditions is a long-overdue step for the industry. However, we hope that the government will also provide support during the transition phase.”
In contrast, consumer advocacy groups have welcomed the new guidelines, emphasizing that they will aid in consumer protection and enhance market choices. A representative from a consumer rights organization remarked, “This is a significant step towards eliminating the disconnect between marketed performance and actual consumer experience.”
Future Initiatives and Broader Framework
Beyond the new mileage testing requirement, the transport ministry is working on broader initiatives to care for environmental impacts and increase consumer awareness regarding vehicle emissions. Future plans may include accessible information systems for car owners that provide insights on emissions while highlighting improvements.
This proactive approach aligns with global trends towards sustainability and aligns with India’s commitment to environmental standards. Officials have indicated that detailed guidelines and public outreach will accompany the rollout of these new measures.
Conclusion
As India gears up for this significant change in automotive testing regulations, it is clear that measuring fuel efficiency with AC operational is essential for reflecting true vehicle performance. The impending regulations underscore the government’s commitment to enhancing transparency and aiding consumers in making informed decisions.
While the introduction of this regulation is a progressive step, its successful implementation will depend on the cooperation of manufacturers, government oversight, and ongoing consumer education efforts.
