Industry Odisha Bureau, Oct 21: CAFE-3 and BS7 emission norms could drive advanced engine tech and hybrids into more cars. Vehicle prices may rise, but electric vehicles could become more competitive.
India plans to roll out tougher clean fuel and emission rules over three years. The changes target the world’s third-largest automobile market. Carmakers are drawing up compliance plans, Mint reported. Buyers, meanwhile, could face higher vehicle prices. Their precise requirements will depend on official regulatory documents.
The first is Corporate Average Fuel Efficiency Phase 3, or CAFE-3. It judges a carmaker’s whole fleet, not each model separately. Firms can balance thirstier models with more efficient ones. Lower fuel use also means lower carbon dioxide emissions. The second, Bharat Stage 7 or BS7, will regulate harmful pollutant emissions. One targets fleet efficiency; the other targets local air pollution.
BS7 is expected to change how emissions are tested, not just limits. Emissions measured in laboratories can differ from those on real roads. Speed, traffic, load and weather all affect what an engine releases. BS7 would therefore bring testing closer to real-world driving. It may also cover more pollutants and testing conditions. Electric vehicles, other powertrains and even tyres could come within its scope. These provisions remain expectations, not finalised rules.
Compliance will not come cheap. Carmakers must invest in advanced engine tech, cleaner combustion and hybrid systems. BS7 adds spending on new testing systems for carmakers and suppliers. Such investment comes before companies can recover it through sales. Mint’s analysis suggests average new-car prices could rise as costlier technology spreads. The increase will vary by vehicle and technology. Competition may also limit how much cost reaches buyers.
The rules could indirectly strengthen the case for electric vehicles (EVs). Petrol and diesel cars could grow more complex and expensive to clean up. EVs produce zero tailpipe emissions, offering carmakers an easier compliance route. Their treatment under CAFE-3 will depend on the final methodology. Zero tailpipe emissions do not mean zero lifecycle impact, however. Battery production and power generation still carry environmental costs. EVs and hybrids usually cost more upfront but can be cheaper to run. Savings depend on driving patterns, energy prices and maintenance. Nor do the rules require an immediate switch to electric.
Component makers could benefit as demand grows for engines, batteries and emission controls. Yet developing new parts requires heavy investment, and gains will not be equal. The bigger prize is closer alignment with global standards. Global carmakers increasingly use India as an export base. Vehicles built for stricter domestic rules adapt more easily for similar overseas markets. Foreign regulators, however, still apply their own certification.
Policymakers must deliver cleaner, more efficient cars without pricing buyers out. Getting that balance right will also shape India’s manufacturing competitiveness.
