New CAFE 3 Norms – New Fuel Rules for Indian Cars, EVs and Hybrids From 2027

India has notified the new Corporate Average Fuel Economy (CAFE) norms for passenger vehicles, bringing tighter fuel-efficiency requirements for carmakers from April 1, 2027. The new rules will remain in force until March 31, 2032 and will apply to new passenger vehicles manufactured or imported for sale in India.

The CAFE 3 framework is designed to improve the overall fuel efficiency of carmakers' fleets while giving them multiple ways to meet the targets. Electric vehicles, hybrids, flex-fuel vehicles, cleaner fuels and fuel-saving technologies will all get recognition under the new framework.

CAFE 3 Norms to Tighten Fuel Efficiency Targets

Under the new rules, the fuel-consumption benchmark will become stricter every year. The benchmark will fall from 3.996 litres per 100km in FY2027-28 to 3.3273 litres per 100km in FY2031-32. This represents an improvement of around 16.7 per cent over five years.

CAFE targets apply to a manufacturer's overall fleet average. This means every individual car does not have to meet the same fuel-efficiency figure. Instead, the average performance of the manufacturer's eligible fleet will be considered. This also means the mix of petrol, diesel, hybrid, electric and other vehicles sold by a manufacturer will play an important role in meeting the new targets.

Heavier Cars Will Face Tighter Targets

The new framework also takes vehicle weight into account. The reference weight has increased from 1,082kg to 1,229kg, reflecting changes in the passenger vehicle fleet. The revised target line is designed to be more weight-sensitive, with relatively softer targets for lighter vehicles and higher fuel-efficiency requirements for heavier vehicles. The 1,229kg figure is only a calculation parameter for the CAFE framework. It does not mean that new cars sold in India will have to weigh 1,229kg.

EVs and Hybrids Get Super Credits

One of the major changes under CAFE 3 is the recognition given to cleaner powertrain technologies. Battery electric vehicles, range-extended electric vehicles, plug-in hybrids, strong hybrids and flex-fuel vehicles can receive super credits in fleet-average calculations. These credits can help manufacturers improve their fleet-level compliance and provide an additional incentive to introduce cleaner powertrains in the Indian market.

Cleaner Fuels Get Recognition

The new CAFE framework also introduces a Carbon Neutrality Factor, which recognises renewable and lower-carbon fuels. This includes ethanol-blended petrol, biofuels and compressed biogas. The provision gives manufacturers another way to improve their fleet-level compliance alongside electrification and improvements in vehicle efficiency.

12 Fuel-Saving Technologies Recognised

The number of recognised fuel-conservation technologies has also increased from four to 12 under the new framework. The technologies include solar-reflective paints, advanced glazing and high-efficiency air-conditioning systems. Manufacturers can receive a concession of 1g CO2/km for each eligible technology, subject to an overall maximum concession of 9g CO2/km. This gives carmakers more options to improve their compliance without relying only on changes to engines or electric powertrains.

Credit Trading Gives Carmakers More Flexibility

The new CAFE rules also provide manufacturers with greater flexibility when meeting their targets. Carmakers can meet their obligations over specified two-year or three-year compliance blocks. Manufacturers that perform better than their prescribed targets can generate credits and carry them forward within the specified blocks. Companies facing a shortfall can also exchange or trade credits with other manufacturers or purchase credits through a buyout mechanism administered by the Bureau of Energy Efficiency.

MIDC and WLTP Testing

The new framework will use both Modified Indian Driving Cycle and Worldwide Harmonized Light Vehicles Test Procedure reporting. This will support India's gradual transition towards globally harmonised vehicle testing practices. Manufacturers with annual sales of fewer than 1,000 units will remain exempt from fleet-average obligations.

What CAFE 3 Means for Car Buyers

The new CAFE rules are aimed at manufacturers and do not provide a direct purchase subsidy or tax reduction for car buyers. However, the regulations could influence the types of vehicles carmakers introduce in India. Manufacturers may increase their focus on EVs, strong hybrids, plug-in hybrids, range-extender EVs, flex-fuel vehicles and other fuel-saving technologies to meet the tighter fleet-average targets. The impact on vehicle prices, features and powertrain choices will depend on how individual carmakers respond to the new rules.

Toyota and Tata Motors Welcome the New Rules

Toyota has welcomed the recognition of multiple technologies under the new framework, including battery EVs, range extenders, plug-in hybrids, strong hybrids and flex-fuel vehicles. The company said combining hybrid technology, electrification and indigenous biofuels could help reduce dependence on imported fossil fuels.

Tata Motors Passenger Vehicles has also welcomed the announcement. MD and CEO Shailesh Chandra highlighted the combination of tighter fuel-efficiency targets and market-based compliance mechanisms. He also said the continued recognition of zero-emission technologies reinforces the role of electrification in long-term emissions reduction.
