India Notifies CAFE 3 Norms for 2027–32: EVs Get 3x Credit, No Special Relief for Small Cars
India has finalised its next phase of passenger-vehicle fuel-efficiency regulations, with the Ministry of Power notifying the Corporate Average Fuel Consumption Standard 2027–32, commonly referred to as CAFE 3.
The new rules will come into effect from April 1, 2027 and remain applicable until March 31, 2032. They will replace the current CAFE 2 framework and tighten the fleet-average fuel-consumption and CO₂-performance requirements that carmakers must meet across their overall sales mix.
The final notification also settles one of the most contentious issues in the industry consultation process: small cars will not receive a separate CAFE concession. At the same time, battery EVs and range-extender EVs retain the strongest compliance advantage through a 3x super-credit multiplier.
What are CAFE norms?
CAFE standards do not impose a single CO₂ or fuel-consumption limit on every individual vehicle.
Instead, they regulate the sales-weighted average fuel consumption of an automaker’s entire passenger-vehicle fleet. This means a company selling heavier or less-efficient vehicles can partly offset them by selling more efficient cars, hybrids or EVs.
The rules apply to M1-category passenger vehicles sold in India, broadly covering passenger cars with seating for up to nine occupants and a gross vehicle weight of up to 3,500kg.
This makes CAFE a portfolio-level regulation rather than a model-specific emission standard.
CAFE 3 starts from April 2027
The final CAFE 3 period runs for five financial years:
April 1, 2027 → March 31, 2032
The framework continues with a weight-linked approach, where the annual target applicable to each manufacturer depends on the sales-weighted average unladen mass of its fleet. Targets become progressively tighter over the period rather than remaining fixed at one level.
Another significant transition is the move toward WLTP-based measurement, replacing the older MIDC-based framework used in the current CAFE cycle. The earlier BEE proposal had already identified WLTP as the basis for the next-generation norms from 2027.
No dedicated CAFE relief for small cars
One of the biggest decisions in the final framework is the removal of a specific concession for small cars.
A September 2025 draft had proposed allowing qualifying sub-4-metre petrol cars weighing up to 909kg to deduct 3g/km of CO₂ from their declared performance for CAFE calculations.
That proposal generated significant disagreement among manufacturers.
Maruti Suzuki and Toyota had supported special treatment for lightweight small cars, arguing that their absolute fuel consumption and emissions are already relatively low. Tata Motors, Mahindra, Hyundai and Kia were among those reported to oppose a separate carve-out.
The final CAFE 3 rules do not include that dedicated 3g/km small-car concession.
However, revisions made during the drafting process produced a flatter weight-based compliance curve, which can still reduce the relative burden on lighter cars compared with some earlier proposals.
EVs get the biggest CAFE advantage
CAFE 3 retains a super-credit mechanism, allowing selected low-carbon powertrains to count as more than one vehicle when calculating a manufacturer's corporate average performance.
CAFE 3 super-credit multipliers
Powertrain | Super Credit |
Battery Electric Vehicle | 3.0x |
Range-Extender EV | 3.0x |
Plug-in Hybrid / Flex-Fuel Strong Hybrid | 2.5x |
Strong Hybrid | 1.6x |
Flex-Fuel Ethanol Vehicle | 1.1x |
This means one BEV effectively counts as three vehicles for this part of the CAFE calculation.
For an automaker with a large ICE portfolio, increasing EV sales can therefore materially improve its corporate-average compliance position.
Strong hybrids retain an advantage — but smaller than EVs
Strong hybrids receive a 1.6x multiplier, considerably lower than the 3x benefit given to BEVs and range-extender EVs.
This has important implications for manufacturers such as Maruti Suzuki and Toyota, which are expanding strong-hybrid portfolios while simultaneously developing EVs.
The structure does not penalise hybrids outright, but clearly places battery EVs higher in the regulatory hierarchy.
Flex-fuel strong hybrids and plug-in hybrids receive a more generous 2.5x multiplier.
Range-extender EVs receive the same 3x credit as BEVs
One particularly notable provision is the treatment of range-extender electric vehicles, or REEVs.
These vehicles primarily use an electric motor to drive the wheels, while a combustion engine operates as an onboard generator to replenish the battery.
Under CAFE 3, REEVs receive the same 3x super-credit as pure battery EVs.
That could become strategically important as manufacturers explore smaller-battery electrification strategies for markets where charging infrastructure or battery costs remain constraints.
Suzuki, for example, has already indicated that it is studying range-extender architectures for compact vehicles, although no India production model has yet been confirmed.
Flex-fuel vehicles get a smaller benefit
Flex-fuel ethanol vehicles receive a 1.1x volume multiplier under the final framework.
Earlier proposals had offered stronger incentives to flex-fuel vehicles, but those benefits were reduced through successive revisions.
That is noteworthy given India's broader policy push toward E20, E85 and potentially E100 ethanol usage.
The final framework still recognises flex-fuel technology, but it does not give it anything close to the compliance advantage enjoyed by EVs.
CAFE 3 introduces credit trading
One of the most consequential changes in the final notification is a formal credit-and-debit mechanism.
If a manufacturer performs better than its prescribed annual target, it can generate CAFE credits.
If it performs worse, it accumulates debits.
These credits will be maintained in a manufacturer-level account or “passbook”.
Manufacturers will also be able to trade credits with other manufacturers, giving the industry more flexibility in meeting fleet-level targets.
This could potentially create an interesting dynamic where companies with high EV or hybrid penetration accumulate credits that have economic value to manufacturers with more carbon-intensive portfolios.
Manufacturers can also buy credits from BEE
If a manufacturer remains short of its target even after using its own or traded credits, it can buy credits from the Bureau of Energy Efficiency.
The notified buyout price starts at:
₹2,500 per g CO₂/km in FY28
and rises by ₹500 per year, reaching:
₹4,500 per g CO₂/km in FY32.
The annual credit-trading window will run from October 1 to October 31.
This adds a direct financial cost to falling short of the required fleet-average performance.
Compliance divided into two blocks
Rather than treating all five years identically, CAFE 3 divides the programme into two compliance blocks:
FY28–FY30: three-year blockFY31–FY32: two-year block
Credits can be carried forward within the relevant compliance block.
This gives automakers some flexibility to manage model launches, EV ramp-up and product-cycle timing without requiring perfect compliance in every individual year.
What CAFE 3 means for carmakers
The biggest strategic consequence is that automakers will increasingly need to manage their entire powertrain mix, rather than optimise individual models in isolation.
A manufacturer with a large SUV portfolio may need more:
EVs
Strong hybrids
CNG models
Flex-fuel vehicles
Lightweight vehicles
More efficient petrol engines
CO₂-reducing technologies
to balance the higher consumption of heavier models.
Companies already selling significant volumes of EVs should have a structural advantage because of the 3x multiplier.
Tata and Mahindra could benefit from EV scale
Tata Motors and Mahindra already have sizeable electric passenger-vehicle portfolios.
As their EV volumes grow, the CAFE super-credit mechanism could help offset emissions from their large ICE SUV line-ups.
This does not mean EVs automatically guarantee compliance, but the 3x multiplier makes every incremental EV sale disproportionately valuable from a CAFE perspective.
Maruti faces a different challenge
Maruti Suzuki's portfolio remains heavily skewed toward lightweight petrol and CNG cars, with strong hybrids playing an increasing role.
Small cars naturally consume less fuel than larger vehicles, but the final rules do not provide a separate compliance concession simply because a vehicle is small.
Maruti therefore has several possible routes:
lightweighting + CNG + strong hybrids + EVs + flex fuel + higher-efficiency petrol engines.
Its future EV sales could become particularly important because BEVs receive nearly twice the super-credit multiplier of conventional strong hybrids.
Could CAFE 3 accelerate hybrid and EV launches?
Most likely, yes.
Because compliance is measured at the manufacturer level, every lower-emission vehicle sold improves the fleet average.
That provides automakers with a regulatory incentive to increase sales of electrified models—not only to meet consumer demand but also to reduce the compliance burden created by larger ICE vehicles.
This could lead to:
More affordable EV variants
Greater hybrid availability
More CNG offerings
Expansion of flex-fuel-compatible engines
Increased lightweighting
Faster adoption of efficient turbocharged engines
Will CAFE 3 make cars more expensive?
There is no automatic price increase built into CAFE 3.
However, meeting stricter fleet requirements can require manufacturers to invest in:
new powertrains
batteries and motors
hybrid systems
lightweight materials
more sophisticated engine management
aerodynamic improvements
transmission upgrades
Those costs could influence future vehicle pricing.
The impact will vary widely by manufacturer because compliance depends on the composition of each company's product portfolio.
CAFE norms are different from BS emission norms
This distinction is important.
Bharat Stage regulations primarily control pollutants such as NOx, particulate matter and hydrocarbons from individual vehicles.
CAFE regulations, by contrast, focus on the fleet-average fuel consumption and CO₂ performance of an entire manufacturer.
A vehicle can therefore comply with BS6 emission standards while still contributing negatively to its manufacturer's CAFE average if it consumes relatively large amounts of fuel.
Auto Punditz Take
The final CAFE 3 framework makes one policy direction particularly clear: India wants manufacturers to reduce emissions at the portfolio level while giving EVs the strongest regulatory incentive.
There is no dedicated small-car exemption, but the framework allows manufacturers several compliance routes rather than imposing an EV-only transition.
That distinction matters.
CNG, strong hybrids, flex fuel, efficient ICE technology and lightweighting can all contribute. But the 3x super-credit given to BEVs and range-extender EVs means electrification offers the biggest mathematical advantage.
The addition of tradable credits could also change corporate strategy. A manufacturer that substantially beats its target may eventually hold something valuable to competitors struggling with heavier or more ICE-intensive portfolios.
For consumers, CAFE 3 may largely remain invisible. But behind the scenes, it is likely to influence which engines get developed, which models receive hybrid or EV versions, how aggressively manufacturers price EVs and even which products survive future generations.
