What Will Change Under CAFE 3 Norms, How will it Impact Car Makers and Buyers?

The automobile sector contributes nearly 15% of India’s GST revenue collections. The sector is estimated to create around 30 million jobs. This growth has made the sector important for the economy.

In FY26, India’s automobile industry recorded one of the best performances in recent years. The sector registered its highest-ever annual sales across all segments. Total vehicle wholesales in the country stood at 2,82,65,515 units, marking a 10.4% increase over the 2,56,09,279 units recorded in FY25.

What made this performance so significant was that every major segment of passenger vehicles, commercial vehicles, two-wheeler, and three-wheelers posted record sales. This similar trend was seen in the FY19 auto boom.

In FY26 the sector also evolved in terms of consumer preference. The SUV segment was one of the most preferred segments for Indian buyers. Petrol vehicles still dominate but are slowly losing share to CNG and alternative fuels.

A rise in vehicle numbers has increased concerns about fuel consumption and emissions. To manage this, the government has taken various steps. The government’s focus has been on reducing emissions, improving fuel efficiency, and promoting cleaner vehicles.

Changes in Government Rules and Policies

The move to BS6 in April 2020 was one of the biggest changes. This was a big step up from BS4 standards. There has also been a push for electric vehicles (EVs) from the government. This has also been helped by tax benefits and other incentives. The government has also pushed for mixing ethanol with petrol.

At the same time, safety rules have gotten stricter, and things like airbags and crash standards are now required.

Alongside this, the introduction of CAFE norms is a result of the idea of making the whole industry more fuel-efficient.

What is CAFE and What Will Change Under CAFE 3?

CAFE stands for Corporate Average Fuel Efficiency.

India introduced CAFE 1 norms in 2017, followed by CAFE 2 norms in 2022. Each phase has gradually tightened fuel efficiency targets, pushing carmakers to improve mileage and reduce emissions.

As the next step in this progression, the government has proposed stricter targets under the third phase. CAFE 3 norms came into force from April 1, 2027. 

According to the plan, carmakers must slowly lower the average fuel consumption of the cars they sell from 3.73 liters per 100 kilometers in 2027 to 3.01 liters by 2032. The flashpoint is a suggested break for some small petrol cars - those that weigh less than 909 kg, have an engine size of up to 1,200 cc, and are no longer than 4,000 mm long. These cars may be able to claim an extra 3g of CO₂ per kilometer reduction in their declared emissions.

Impact on Carmakers

Carmakers will have to reduce carbon emissions further and improve fuel efficiency across their lineup. Large SUVs and petrol-heavy models will come under pressure.

To meet the new targets, carmakers will need to invest heavily. Many companies may shift focus to smaller engines. Hybrid and electric vehicles could gain more attention and lightweight materials may also be used widely.

However, not all players are equally prepared. Carmakers such as Maruti and Toyota have welcomed the relaxation, claiming that stricter uniform targets would disproportionately raise costs for entry-level models. On the other hand, Tata Motors, Mahindra and Hyundai disagree that the efficiency targets must be uniform. They believe bending rules for lighter cars disturbs engineering priorities and hampers carmakers that invest heavily in safety and high priced products.

What Would It Mean for Buyers

For buyers, the overall impact would be mixed.

One clear effect of CAFE 3 norms will be on the pricing of cars. Cars are expected to become more expensive. This is because carmakers often pass on the cost of new technology and compliance to the buyers. There may also be a shift in available choices. Large petrol SUVs could become less common as companies adjust their portfolios. Instead, buyers would prefer hybrids and electric vehicles.

On the other hand, the norms would offer better fuel efficiency for the vehicles. This may reduce running costs over time.

Conclusion

Carmakers will have to deal with higher costs, technology changes, and adjustments in their product mix. In the near term, this could lead to pricing pressure and margin challenges across the industry.

But in the long term, the shift may benefit both the environment and consumers.

Impact on Auto Stocks

From April 1 to April 17, 2026, the Nifty Auto index has shown a mixed but slightly positive trend. It rose from 24,238.85 on April 1 to 26,435.00 on April 17. This reflects a gain of around 9.6%.

However, major carmaker stocks have fallen from the same period.
