Small Car Definition Divides Carmakers Ahead of 2027 Emission Mandate

India’s auto industry is sharply divided over how to define small cars under the upcoming CAFÉ 3 emission norms. While Maruti Suzuki and allies support weight-based concessions, Tata Motors and others argue for affordability-based criteria, citing safety and market fairness concerns. - Industry Split Over Small Car Classification

, Toyota, Honda, and Renault—holding 49% market share—support a Bureau of Energy Efficiency (BEE) draft that proposes weight-based relaxation for small cars. , , and oppose this, arguing it could distort competition and unfairly benefit manufacturers with lightweight portfolios. - Affordability vs. Weight: The Core Disagreement Some OEMs argue that affordability should be a key criterion, not just weight. They point out that many sub-909 kg cars are priced close to ₹10 lakh, undermining the assumption that lighter cars are more affordable. The price gap between two-wheelers and entry-level four-wheelers is also cited as a reason to consider affordability. - Tata Motors Flags Safety Risks Tata Motors MD Shailesh Chandra criticized the weight-based definition as arbitrary and warned it could dilute safety standards. He noted that no car under 909 kg currently meets BNCAP safety ratings, and relaxing norms for such vehicles could reverse hard-won safety gains. - Implications for Maruti Suzuki’s Portfolio Maruti Suzuki, India’s market leader, has a large portfolio of sub-909 kg models like the Alto, Wagon R, and Celerio. Weight-based concessions would directly benefit its compliance with CAFÉ 3 norms, which tighten CO₂ targets to 88.4 gm/km from 113 gm/km under CAFÉ 2. - Regulatory Stakes and Market Impact The CAFÉ 3 norms, effective April 2027, impose steep penalties for non-compliance. With no consensus within SIAM, the debate over how to define small cars could shape the competitive landscape, influence product strategies, and affect the pace of India’s transition to safer, greener mobility.
