India’s new fuel-economy framework tightens fleet targets through 2032, while giving carmakers more options to comply through cleaner fuels, electrification and fuel-saving technologies
Ministry of Power has notified new Corporate Average Fuel Economy (CAFE) norms for passenger vehicles, effective from April 1, 2027. Applicable until March 31, 2032, the framework will cover new passenger vehicles manufactured or imported for sale in India.
The announcement sets out progressively tighter fuel-consumption targets over five years. Alongside improving conventional vehicles, manufacturers will receive recognition for electric vehicles, strong hybrids, plug-in hybrids and flex-fuel vehicles, giving them multiple routes to meet their obligations.
Fuel-Consumption Benchmark To Tighten By 16.7%
Under the new framework, the fuel-consumption benchmark will reduce from 3.996 litres per 100 km in FY2027–28 to 3.3273 litres per 100 km in FY2031–32. This represents approximately 16.7% lower fuel consumption across the period, with targets tightening each year.
CAFE applies to a manufacturer’s fleet average, rather than requiring every individual car to achieve the same mileage. The framework therefore influences the overall mix of vehicles a manufacturer sells, alongside the efficiency of individual models.
The revised target line also provides relatively softer targets for lighter vehicles and greater fuel-efficiency requirements for heavier vehicles. Reference weight increases from 1,082 kg to 1,229 kg, reflecting changes in the passenger vehicle fleet. This is a parameter used in the framework, rather than a prescribed weight for new cars.
EVs, Strong Hybrids And Flex-Fuel Vehicles Get Recognition
A key provision is the inclusion of multiple powertrain technologies for “super credits” in fleet-average calculations. These cover battery electric vehicles, range-extended EVs, plug-in hybrids, strong hybrids and flex-fuel vehicles.
These credits give manufacturers an additional compliance incentive to introduce and sell such vehicles. The government’s announcement does not specify the individual credit multipliers applicable to each category.
The framework also introduces a Carbon Neutrality Factor to recognise renewable and low-carbon fuels, including ethanol-blended petrol, biofuels and compressed biogas. This adds another compliance pathway alongside electrification and improvements in vehicle efficiency.
Fuel-Saving Technologies Get Wider Scope
The number of recognised fuel-conservation technologies has increased from four to twelve. Examples highlighted by the government include solar-reflective paints, advanced glazing and high-efficiency air-conditioning systems.
Manufacturers can receive a concession of 1 gram of CO2 per kilometre for each eligible technology, subject to an overall cap of 9 grams per kilometre. This gives carmakers more scope to improve their compliance performance through changes beyond the engine or electric powertrain.
Credit Trading And Flexible Compliance
Manufacturers may opt to meet their obligations over specified two-year or three-year compliance blocks. This provides flexibility as companies introduce new models and change their powertrain mix.
Car makers performing better than their prescribed targets will generate credits, which can be carried forward within the specified blocks. Manufacturers facing a shortfall can also exchange or trade credits with other companies, or purchase credits through a buyout mechanism administered by the Bureau of Energy Efficiency.
Reporting will take place under both the Modified Indian Driving Cycle (MIDC) and the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), supporting a gradual transition in testing practices. Manufacturers with annual sales below 1,000 units remain exempt from fleet-average obligations.
What It Means For Car Buyers
For buyers, the new framework could encourage a wider choice of efficient petrol cars, hybrids, EVs and alternative-fuel models as manufacturers work towards tighter targets. It also creates an incentive to introduce fuel-saving technologies across vehicle ranges.
However, these provisions concern manufacturer compliance. They do not announce a direct purchase subsidy or tax reduction for customers. The eventual impact on vehicle prices, equipment and powertrain availability will depend on how individual carmakers respond.
Toyota And Tata Motors Welcome New Norms
Toyota welcomed the framework’s recognition of multiple technologies, including battery EVs, range extenders, plug-in hybrids, strong hybrids and flex-fuel vehicles. The company said combining efficient hybrid systems with electrification and indigenous biofuels could help reduce dependence on imported fossil fuels. It also praised the government’s consultation process and highlighted the regulation’s contribution towards India’s energy independence and climate goals.
Tata Motors Passenger Vehicles also welcomed the announcement, with MD and CEO Shailesh Chandra highlighting the combination of ambitious fuel-efficiency targets and market-based compliance mechanisms. He said continued recognition of zero-emission technologies reinforces electrification’s role in long-term decarbonisation. Chandra added that regulatory clarity would help manufacturers plan investments and accelerate innovation, while reaffirming Tata’s commitment to electric mobility and other technologies that meaningfully reduce emissions.
