The Government has notified new Corporate Average Fuel Economy (CAFE-III) norms for passenger vehicles, introducing a tighter fuel-efficiency framework for the automobile industry from the 2027-28 financial year.
The new framework will remain applicable until 31 March 2032 and will cover new passenger vehicles manufactured or imported for sale in India.
Editorial Insight
Key Highlights
Important points readers should notice.
Effective From: 1 April 2027.
Validity: Through 31 March 2032.
Coverage: New M1-category passenger vehicles manufactured or imported for sale in India.
Fuel-Efficiency Benchmark: Tightens from 3.9 litres/100 km in 2027-28 to 3.32 litres/100 km in 2031-32.
Approach: Weight-sensitive fleet-average fuel-efficiency targets.
Under the notified framework, the fuel-consumption benchmark will become progressively stricter over the five-year period. The benchmark is set at 3.9 litres per 100 kilometres in 2027-28 and moves down to 3.32 litres per 100 kilometres by 2031-32, representing an improvement of more than 16% over the period.
CAFE norms are applied at the manufacturer's fleet level, rather than treating the fuel efficiency of every individual car as a separate corporate target. The framework therefore links a manufacturer's overall vehicle mix and average efficiency with its compliance requirements.
The revised system also adopts a more weight-sensitive approach. Lighter vehicles receive relatively softer targets while heavier vehicles face stronger fuel-efficiency requirements, creating a framework that takes vehicle weight into account.
Editorial Analysis
Why This Matters
The new norms are important because fuel efficiency affects both vehicle operating costs and India's overall fuel demand. For automobile manufacturers, meeting progressively tighter fleet-average requirements could encourage greater use of efficient engines, hybrid systems, electric vehicles and other technologies that improve overall fleet efficiency. For consumers, the effect will depend on how manufacturers adjust their vehicle portfolios and pricing strategies. The new rules do not mean that every individual car sold from April 2027 must deliver exactly 3.9 litres per 100 kilometres. The requirement is based on the manufacturer's overall fleet calculation. The framework also gives manufacturers flexibility to pursue different technological routes to improve their average performance.
