India notifies CAFE 3 fuel efficiency norms for 2027-2032, drops small car carve-out

India's Ministry of Power has notified the CAFE 3 fuel efficiency norms, setting stricter corporate average fuel economy targets for carmakers from April 2027 through March 2032. The final rules drop a proposed 3 g/km concession for petrol cars weighing up to 909 kg. Instead, the reference weight in the CAFE formula moves from 1,170 kg to 1,229 kg with a flatter adjustment curve, which gives lighter fleets a softer target and applies stricter limits to heavier vehicles. Battery electric vehicles and range-extended EVs get a 3x super-credit toward fleet compliance, plug-in hybrids and strong hybrids on flex fuel get 2.5x, strong hybrids get 1.6x, and flex-fuel vehicles get 1.1x. The rules also introduce a credit-debit passbook system with trading between manufacturers and an annual October window. Buyout prices start at Rs 2,500 per g/km in FY28 and rise to Rs 4,500 by FY32.

Interesting that they settled the small car fight by moving the reference weight instead of a carve-out. Lighter cars get an easier target under the new formula, heavier SUVs get squeezed. That is a cleaner way to do it politically, though the real test is whether enforcement and the credit market actually work.

The super-credit structure is worth watching. BEVs and range extenders count 3x, strong hybrids 1.6x, flex fuel only 1.1x. That pushes automakers toward full electrification rather than just hybridizing. But if EV sales stall, those credits become expensive fast, and the buyout price climbs from Rs 2,500 to Rs 4,500 per g/km.

Does anyone know how the CAFE credit trading window interacts with the vehicle type approval process? The October window is narrow, and if a manufacturer misses it they carry debits into the next block. That could make compliance lumpy, especially for companies relying on imported EV components or supply chain delays.

This is a better design than the draft. A carve-out for small cars would have been an indirect subsidy to one dominant maker. Changing the fleet weight curve keeps the incentive structure broad, but the credit buyout price at Rs 2,500 per g/km is low enough that some manufacturers may treat it as a compliance cost rather than invest in cuts.

The credit-debit system with a passbook and annual October trading window is the part that will determine whether CAFE 3 actually cuts emissions. If credits are cheap and easy to buy, the standard becomes a fee. If the BEE audits real-world fuel economy properly, it could push genuine efficiency gains.
