India’s automobile sector could soon face a major regulatory shift, with NITI Aayog recommending that fuel efficiency norms be expanded across all vehicle categories. The proposal is part of a broader strategy to reduce dependence on conventional fuels and strengthen energy resilience as global supply uncertainties continue to shape fuel markets.
The recommendation comes as concerns over fuel security and rising oil volatility remain in focus, particularly following recent geopolitical tensions in West Asia. By broadening Corporate Average Fuel Efficiency, or CAFE, standards, policymakers hope to lower fuel consumption while nudging manufacturers towards cleaner technologies.
Fuel rules may cover all vehicle categories
At present, fuel efficiency standards are not applied uniformly across the automotive sector. NITI Aayog has proposed that CAFE norms should extend beyond passenger vehicles to include two-wheelers, commercial vehicles and buses, bringing a larger share of the industry under a common efficiency framework.
The move is expected to push automakers to improve overall fleet efficiency rather than optimise select models. Instead of relying mainly on vehicle size-based benchmarks, the next phase of regulations will likely focus on emissions and fuel performance across an entire portfolio.
This could reshape product planning, especially for manufacturers with high-emission fleets, as companies would need to balance consumer demand with regulatory compliance.
EV growth and fuel transition in focus
The proposal also highlights the need to significantly expand electric mobility. While electric vehicles have made strong gains in the three-wheeler market, adoption in two-wheelers, four-wheelers and commercial vehicles remains relatively low.
NITI Aayog has set a target to increase EV penetration across major segments to 65 per cent by 2035, a steep rise from current levels. To support this shift, the report stresses affordable financing, lower purchase costs and stronger incentives.Alongside electrification, alternative fuels are also becoming central to the transition strategy.

CAFE-3 to influence vehicle design and engines
The upcoming CAFE-3 framework is expected to bring deeper changes to vehicle engineering. Manufacturers may increasingly use lighter materials, improved aerodynamics and more efficient powertrains to reduce fleet-wide emissions.
The government has also asked automakers to prepare for E25 fuel, which would increase ethanol blending in petrol. Flex-fuel engine development is likely to gain momentum as India explores fuel blends beyond current levels.

Together, these shifts suggest that the future of mobility in India will depend less on traditional petrol and diesel, and more on efficiency, electrification and fuel flexibility.
