Automakers including Toyota, Suzuki, Hyundai and MG expected to launch E100-compatible vehicles in the coming months
India has taken a major step towards alternative fuels, with Union Minister for Road Transport and Highways Nitin Gadkari announcing that regulations allowing the use of 100% ethanol (E100) as automotive fuel have now been officially signed and approved.
Speaking at an event in Nagpur, Gadkari revealed that he signed the file on Friday evening, formally clearing the regulatory path for E100-compatible vehicles in India. The move is expected to accelerate the introduction of flex-fuel vehicles (FFVs) capable of running on pure ethanol, while reducing the country’s dependence on imported crude oil.
E100 Fuel Gets Legal Backing
While India has already achieved nationwide availability of E20 petrol in many regions and continues to expand ethanol blending, the latest development takes things a step further. The newly approved regulations legally authorize the use of E100 fuel, allowing automakers to develop and sell vehicles specifically engineered to operate on pure ethanol.

The proposed changes to the Central Motor Vehicles Rules (CMVR) also support wider adoption of alternative fuels including E85 (85% ethanol), B100 biodiesel and hydrogen-CNG blends. According to Gadkari, the idea of using 100% ethanol as automotive fuel was initially met with skepticism. However, years of policy support, increasing domestic ethanol production and advancements in flex-fuel technology have now made it a practical reality.
More Flex-Fuel Vehicles On The Way
The announcement comes shortly after the launch of flex-fuel variants of Hero Splendor+ and HF Deluxe motorcycles capable of operating on E85 ethanol blends. Gadkari stated that several major automakers are preparing to introduce ethanol-compatible vehicles in the Indian market within the next month and a half.
Companies mentioned include Toyota, Suzuki, Hyundai and MG. Last week, Gadkari and Union Petroleum Minister Hardeep Singh Puri also showcased a flex-fuel version of the Maruti WagonR, highlighting the government’s push towards cleaner and domestically produced fuels.
Reducing Oil Imports, Supporting Farmers
One of the key objectives behind E100 adoption is reducing India’s reliance on imported crude oil. India currently spends billions of dollars annually on fuel imports, making the economy vulnerable to fluctuations in global oil prices.
Ethanol production, on the other hand, relies on domestically available agricultural feedstock such as sugarcane, corn and surplus grains. Increased demand for ethanol is expected to provide additional income opportunities for farmers while strengthening India’s energy security. The government believes wider ethanol adoption can help reduce the national fuel import bill and create a more sustainable fuel ecosystem.
Challenges Remain
While the regulations have now been approved, large-scale E100 adoption will require significant infrastructure development. Ethanol has different storage and handling requirements compared to petrol, owing to its moisture absorption characteristics and corrosive nature. Oil marketing companies are expected to gradually establish dedicated E100 dispensing stations across key cities and agricultural regions.
Vehicle manufacturers will also need to expand their flex-fuel vehicle offerings to support the transition. There are also technical considerations, as E100-compatible vehicles require specially calibrated engines, fuel systems and materials designed to withstand higher ethanol concentrations.
While E100 regulations pave the way for future flex-fuel vehicles, questions remain regarding India’s existing vehicles. Several older vehicles were originally engineered for lower ethanol blends. In one example shared on social media, a 2022 Kia Sonet owner’s manual explicitly advises against using fuel containing more than 10% ethanol. As India moves towards higher ethanol adoption, automakers and regulators may need to provide greater clarity on compatibility, warranty implications and fuel recommendations for millions of vehicles already in operation.
Part Of India’s Multi-Fuel Future
The approval of E100 regulations is part of the government’s broader strategy to diversify India’s transportation energy mix. Alongside ethanol, policymakers continue to support electric vehicles, biodiesel, CNG, LNG, hydrogen and green hydrogen technologies.
Gadkari also announced that Nagpur will soon host a pilot project featuring hydrogen-powered buses and dedicated hydrogen refuelling infrastructure, further underlining the government’s commitment to alternative fuels. With the legal framework now in place, India is set to enter the next phase of ethanol mobility, potentially becoming one of the world’s largest markets for flex-fuel and ethanol-powered vehicles.
