India amends vehicle rules to cover E85 and E100 flex fuel vehicles

India’s Ministry of Road Transport and Highways said on 26 October 2026 it had notified amendments to vehicle rules. According to the ministry, amendments to the Central Motor Vehicles Rules, 1989, expressly include E100 alongside E85 in emission certification. The ministry said E85 is a petrol and ethanol blend containing up to 85 per cent ethanol by volume. It said E85 and E100 are intended only for vehicles designed and certified to use them. The ministry said the notification does not require owners of existing vehicles to switch to E85 or modify them.
