A month after India introduced E85 fuel, a high-ethanol blend for flex-fuel vehicles, concerns persist among consumers and the automotive industry. These vehicles are designed to run on higher blends such as E85 (85% ethanol, 15% petrol) and E100 (nearly pure ethanol), unlike petrol-powered vehicles compatible with E20 fuel (20% ethanol, 80% petrol). The decision to make E85 available at select outlets is aimed at reducing dependence on imported crude oil. With around 90% of the country’s crude oil sourced from overseas, global geopolitical tensions have repeatedly exposed the vulnerabilities of India’s energy ecosystem. Promoting ethanol as a mainstream fuel for flex-fuel vehicles is an ambitious step towards achieving energy self-reliance and reducing greenhouse gas emissions. However, a carefully calibrated execution that inspires public confidence is a must to facilitate this transition.
India has already demonstrated the benefits of ethanol blending through substantial foreign exchange savings and the creation of a robust domestic ethanol industry. Higher ethanol demand can provide farmers with additional income opportunities by expanding the market for sugarcane and maize. The decision to price E85 at a discount to conventional petrol could make it a good option for consumers using compatible vehicles, even after accounting for its relatively lower fuel efficiency.
Yet optimism must be tempered with realism. Automobile manufacturers have expressed apprehensions about engine compatibility, corrosion, fuel systems and long-term durability. These issues deserve serious attention rather than outright dismissal. Without clear communication, there is a genuine risk of widespread confusion, misfuelling (putting the wrong type of fuel into a vehicle) and misplaced scepticism. Infrastructure, vehicle readiness, fuel quality standards and technical training must evolve alongside fuel availability. There is a need to recognise that biofuels are not an immediate replacement for fossil fuels. Preparedness, transparency and stakeholder collaboration — not haste — will determine whether E85 becomes a successful model or a missed opportunity.
