Road ministry allows E100 pure-ethanol fuel for flex-fuel vehicles

The Ministry of Road Transport and Highways has amended the Central Motor Vehicles Rules, 1989 to permit fuels with up to 100% ethanol (E100), paving the way for flex-fuel vehicles. Changes to Rules 115 and 115E add E100 alongside E85, but only for factory-built flex-fuel models. The ministry clarified E10 or E20 compatibility does not mean E85 suitability.
