CAFE III norms explained: India's new fuel efficiency and CO2 rules for cars from 2027

India's third phase of Corporate Average Fuel Efficiency (CAFE) norms will apply to passenger vehicles from April 1, 2027, through March 31, 2032. The rules set a fleet average fuel consumption target that tightens every year, starting at 3.996 litres of petrol equivalent per 100 km in FY28 and falling to 3.3273 L/100 km in FY32. That translates to roughly 94.8g and 78.9g of CO2 per km respectively, based on a reference fleet weight of 1,229 kg. CAFE III drops the proposed 3g/km concession for cars under 909 kg and instead uses a flatter target curve. It also introduces a credit debit system where automakers that beat their target earn credits and those that miss can buy credits from the Bureau of Energy Efficiency or trade with other manufacturers. The buyout price starts at 2,500 rupees per gram of CO2/km and rises to 4,500 rupees by FY32. BEVs and range extended EVs get a super credit factor of 3, while strong hybrids get 1.6. Industry estimates suggest compliance could add 20,000 to 1.25 lakh rupees to vehicle prices by FY32, though fuel savings may offset part of that over a few years.

Good breakdown. The interesting part is that the small car concession got scrapped but the slope change does similar work. Also worth noting the BEE credit price rises from 2500 to 4500 per g/km over five years. That is a real cost signal for automakers that keep missing targets.

The fleet average target dropping from 3.996 to 3.327 L/100 km by FY32 is roughly 16.7% tighter. With the super credits for BEVs and hybrids, the actual CO2 outcome depends on how many EVs get sold. Worth watching whether the credit trading market actually has liquidity or just becomes a fee.

CAFE targets are fine on paper, but the compliance blocks FY28-FY30 and FY31-FY32 mean credits lapse after each block. That could push manufacturers to bank credits early rather than trade them. Also curious how BEE verifies the efficiency tech claims like start-stop and advanced glazing. Those are easy to overstate.

Clear explainer. One thing that stands out is the removal of the 3g/km concession for cars under 909 kg. The final formula instead flattens the curve and raises reference weight to 1229 kg. That shifts the fight from a small car carve out to the overall fleet math.

The buyout price structure is the real policy signal. Starting at 2500 and stepping up 500 each year tells OEMs the regulator expects tightening to bite. But if buyout is always available, it can act as a price ceiling on credits. Need to see if BEE caps how much of a deficit can be paid off rather than earned back.

Useful read. The fuel saving math from ForeSee is worth checking: a 3.0 L/100 km car versus 4.2 saves about 15,840 rupees a year at 110 rupees a litre. That makes the 1 lakh price premium payback in around six years, not seven, if you use simple division. Small detail but relevant for buyers.
