India's CAFE-III draft lets automakers earn credits for start-stop systems, regenerative braking, and flex-fuel engines, a non-EV path to stricter fuel targets.
India's proposed CAFE-III fuel efficiency rules will let automakers earn compliance credits for technologies that do not require a plug. Start-stop systems, regenerative braking, and flex-fuel engines all qualify, according to the draft framework circulated by the Bureau of Energy Efficiency.
The credit system gives manufacturers a way to meet stricter fuel economy targets without relying entirely on electric vehicle sales. That matters in a market where EVs still account for less than 3% of new car registrations. A mass-market hatchback fitted with a start-stop system and a flex-fuel engine could earn enough credits to offset a less efficient SUV in the same model lineup.
The draft also proposes separate incentives for flex-fuel vehicles that run on blends of petrol and renewable ethanol or methanol. Those credits stack on top of the technology credits, creating a larger compliance cushion for automakers that invest in both paths.
The rules are not final. The Bureau of Energy Efficiency is accepting comments through June. Industry groups have already flagged concerns about the cost of retrofitting entry-level models with regenerative braking hardware, where the added ₹8,000-10,000 per unit could erase margins on cars priced below ₹5 lakh.
