What Happened

Automobile manufacturers have called on the government to lower the price of high-ethanol fuels (E85 and above) and extend tax incentives for flex-fuel vehicles (FFVs) to accelerate adoption.
India mandated nationwide E20 fuel (20% ethanol blend) from April 1, 2026 — achieving this target five years ahead of the original 2030 deadline.
Following the E20 rollout, the government confirmed that a draft notification for E85 fuel (85% ethanol blend) is nearly ready, signalling a push toward high-blend fuels.
Major carmakers including Maruti Suzuki and Toyota are developing FFV platforms capable of running on any blend from E20 to E85, with Maruti Suzuki planning to begin mass production of FFVs.
The industry's ask includes GST rationalisation to reduce the effective price of high-ethanol fuels, which currently remain more expensive than standard petrol despite lower production costs for ethanol from domestic feedstocks.

Static Topic Bridges

Ethanol Blended Petrol (EBP) Programme

The Ethanol Blended Petrol Programme is a Government of India initiative to blend domestically produced ethanol with petrol, primarily to reduce crude oil imports, lower carbon emissions, and support farmers through enhanced sugarcane and foodgrain demand.

The programme is administered by the Ministry of Petroleum and Natural Gas; ethanol procurement is done by Oil Marketing Companies (OMCs) like Indian Oil, HPCL, and BPCL.
Blending targets have been progressively raised: 5% (E5) → 10% (E10) → 20% (E20, achieved April 2026) → 27% (E27, target by 2030).
NITI Aayog's 2021 roadmap (Roadmap for Ethanol Blending in India 2020–25) advanced the E20 target from 2030 to 2025; India achieved it in 2026.
India requires approximately 13.5 billion litres of ethanol annually for E20 compliance, sourced from sugarcane derivatives (54%) and foodgrains such as surplus rice and maize (46%).
E20 alone is estimated to save approximately Rs 43,000 crore annually in foreign exchange by reducing crude oil import volumes.

Connection to this news: The EBP programme's progression from E20 to E85 is the policy backdrop for carmakers' demands — a move to high-blend fuels requires FFV-capable engines and a reliable, price-competitive supply of high-ethanol fuel, neither of which exists at scale yet.

Flex-Fuel Vehicle (FFV) Technology

A flex-fuel vehicle is an automobile with an internal combustion engine capable of running on any ratio of petrol to ethanol — typically anywhere from E0 (pure petrol) to E85 (85% ethanol, 15% petrol) or even E100 (pure ethanol).

FFVs use modified fuel injection systems, ethanol-compatible fuel lines, and engine management software that automatically adjusts air-fuel ratios based on the ethanol content detected by sensors.
Ethanol has a higher octane rating (~113 RON) than standard petrol (~91–95 RON), providing better anti-knock properties and allowing higher compression ratios in optimised engines.
However, ethanol has approximately 34% lower energy density than petrol, meaning FFVs running on high-ethanol blends achieve lower fuel economy per litre.
Brazil is the global leader in FFV adoption — nearly 90% of new cars sold in Brazil are FFVs — driven by decades of ProAlcool (National Alcohol Programme) policy support since 1975.
In India, the Ministry of Road Transport and Highways (MoRTH) issued a notification in 2021 mandating that new vehicles meet BS-VI norms while also being compatible with E20 by 2023 and E100 by 2025 (for flex-fuel variants).

Connection to this news: Carmakers are investing in FFV platforms to be ready for India's high-ethanol future, but argue that without tax breaks making high-ethanol fuel cheaper than petrol (as in Brazil), consumers will have no financial incentive to choose high-blend fuels — defeating the purpose.

Biofuels Policy and National Policy on Biofuels 2018

India's National Policy on Biofuels (NPB) 2018, revised in 2022, provides the overarching framework for production, distribution, and blending of biofuels including ethanol, biodiesel, and advanced biofuels.

The 2018 policy introduced an "indicative" target of 20% blending for ethanol in petrol and 5% for biodiesel in diesel by 2030; the 2022 revision advanced the ethanol target to 2025.
Permissible feedstocks for ethanol production include sugarcane juice, B-heavy molasses, C-heavy molasses, damaged/surplus foodgrains (rice, wheat, maize), sugarbeet, and sweet sorghum.
Second-generation (2G) ethanol from lignocellulosic biomass (agricultural residues like paddy straw) is promoted under the policy to avoid food-fuel competition.
IOCL's first commercial 2G ethanol plant, at Panipat, Haryana, with a capacity of 3 crore litres per year, became operational in 2023.
The policy is categorised under the broader Panchamrit commitments India made at COP26 (2021): achieving net-zero emissions by 2070, 50% power from renewables by 2030, reducing emissions intensity of GDP by 45% by 2030.

Connection to this news: The carmakers' push for cheaper high-ethanol fuels and FFV tax breaks directly aligns with the stated objectives of the NPB 2018 — but requires coordinated action between the petroleum ministry (fuel pricing), finance ministry (GST rates), and transport ministry (vehicle standards).

India's Energy Security and Import Dependence

India is the world's third-largest oil consumer and importer, meeting approximately 85–87% of its crude oil demand through imports. The crude oil import bill reached approximately USD 132 billion in 2023-24, making it a significant pressure on India's current account balance.

Every USD 10 increase in global crude oil prices adds approximately Rs 1 lakh crore to India's annual import bill.
Ethanol blending reduces petroleum consumption: achieving E20 nationwide saves approximately 3 billion litres of petrol annually.
The EBP programme also benefits farmers by providing an additional demand channel for sugarcane and surplus foodgrains, supporting agricultural incomes.
Carbon emissions: ethanol combustion produces approximately 50–60% lower lifecycle greenhouse gas emissions than petrol, depending on the feedstock.

Connection to this news: The economic rationale for the industry's push — cheaper high-ethanol fuels and FFV tax breaks — is ultimately grounded in India's structural energy security challenge. If high-ethanol fuels are competitively priced, consumers and the economy gain from reduced crude dependence, lower emissions, and stronger agricultural linkages.
