The Centre has approved regulations allowing the use of 100% ethanol (E100) as a fuel for vehicles, creating a framework for manufacturers and fuel companies to introduce ethanol-powered mobility solutions.
The decision takes the country's ethanol programme beyond petrol blending and permits vehicles designed to run entirely on ethanol.
The approval was announced by Union Road Transport and Highways Minister Nitin Gadkari during a bio-energy conference in Nagpur.
The new regulations are expected to support the launch of flex-fuel vehicles in India. Maruti Suzuki has already showcased a flex-fuel version of the WagonR, while Hero MotoCorp has introduced motorcycles that can operate on pure ethanol.
According to the minister, Toyota, Hyundai and MG are also working on ethanol-compatible models.
These vehicles require dedicated fuel systems and engine calibration because ethanol differs from petrol in its physical properties.
India imports more than 85% of its crude oil requirement, and the government has been encouraging alternative fuels to reduce dependence on overseas supplies.
The E100 framework adds another option alongside electric vehicles, CNG, hybrids, and hydrogen-powered transport.
The regulatory approval removes one hurdle, but commercial adoption will depend on fuel supply and distribution networks.
Dedicated E100 filling stations, storage facilities and transport systems will be needed before the fuel becomes available.
Vehicle testing, certification and emission standards will also need to be aligned with the new regulations as manufacturers prepare commercial launches.
