Automakers including Toyota, Suzuki, Hyundai and MG are expected to launch e100-compatible vehicles in the coming months
India has taken a big step towards alternative fuels, with Union Minister for Road Transport and Highways Nitin Gadkari announcing that rules allowing the use of 100% ethanol (E100) as automotive fuel have come into force. Now officially signed and approved.
Speaking at an event in Nagpur, Gadkari revealed that he signed the file on Friday evening, formally approving the regulatory pathway for E100-compliant vehicles in India. This move is expected Accelerate the introduction of flex-fuel vehicles (FFVs) are capable of running on pure ethanol, reducing the country’s dependence on imported crude oil.
E100 fuel gets legal support
While India has already achieved nationwide availability of E20 petrol in many areas and continues to expand ethanol blending, the latest development takes things a step further. Newly approved regulations legally authorize the use of E100 fuel, allowing automakers to develop and sell vehicles specifically engineered to run on pure ethanol.

The proposed changes in the Central Motor Vehicles Rules (CMVR) support wider adoption of alternative fuels including E85 (85% ethanol), B100 biodiesel and hydrogen-CNG blends. According to Gadkari, the idea was to use 100% ethanol as automotive fuel. initially faced skepticism. However, years of policy support, increased domestic ethanol production, and advances in flex-fuel technology have now made this a practical reality.
More flex-fuel vehicles on the way
The announcement comes soon after the launch of flex-fuel variants of the Hero Splendor+ and HF Deluxe motorcycles capable of running on E85 ethanol blend. Gadkari said that many major automakers are preparing to introduce ethanol-compatible vehicles in the Indian market within the next one and a half months.
The companies mentioned include Toyota, Suzuki, Hyundai and MG. Last week, Gadkari and Union Petroleum Minister Hardeep Singh Puri had also showcased a flex-fuel version of the Maruti WagonR, highlighting the government’s push towards clean and domestically produced fuel.
Reducing oil imports, supporting farmers
One of the major objectives behind the adoption of E100 is to reduce India’s dependence 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, depends on domestically available agricultural feedstock such as sugarcane, corn and surplus grains. The increasing demand for ethanol is expected to strengthen India’s energy security as well as provide additional income opportunities for farmers. The government believes that widespread ethanol adoption can help reduce the national fuel import bill and create a more sustainable fuel ecosystem.
Challenges remain
Although regulations have now been approved, large-scale E100 adoption will require significant infrastructure development. Due to its moisture absorption characteristics and corrosive nature, ethanol has different storage and handling requirements than petrol. It is expected that oil marketing companies will gradually set up dedicated E100 distribution stations in major cities and agricultural areas.
Automakers will also need to expand their flex-fuel vehicle offerings to support the transition. There are also technical considerations, as E100-compliant vehicles require specially calibrated engines, fuel systems, and materials designed to withstand higher ethanol concentrations.
While the E100 rules pave the way for future flex-fuel vehicles, questions remain regarding India’s existing vehicles. Many older vehicles were originally engineered for low ethanol blends. In an example shared on social media, the 2022 Kia Sonet owner’s manual clearly 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 the 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. Along with 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 of hydrogen-powered buses and dedicated hydrogen refueling infrastructure, underscoring the government’s commitment towards the alternative fuel. Now with the legal framework 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.
