what happened
India has changed its vehicle regulations to officially cover E100, a fuel made of pure ethanol, for cars certified to run on flexible fuels, according to Moody's. Under the new rules, E100 is now listed alongside E85 in the sections dealing with emission standards and vehicle testing. The notice was published in the Official Gazette on 23 October.
The change does not allow ordinary petrol cars or vehicles built for E20 to switch to E100. Only models that carmakers design and certify for these fuels may use them. Maruti Suzuki has shown a flex-fuel Wagon R that can run on blends from E20 up to E100. The notification alone does not mean E100 will reach fuel stations soon or that compatible cars will be sold in volume.
why it matters
The move fits India's push to use more domestic ethanol and reduce reliance on imported crude. Higher blends could add biofuel demand and trim petrol use in compatible cars, but the scale of any effect depends on ethanol production economics, vehicle costs and fuel infrastructure.
