Ministry of Road Transport and Highways (MoRTH) updates rules to facilitate E85/E100 flex fuel vehicles

The Ministry of Road Transport and Highways (MoRTH) has notified amendments to the Central Motor Vehicles Rules, 1989, to facilitate the adoption and emission certification of E85 and E100 flex fuel vehicles. The rules include E100 alongside E85 and update biodiesel-related provisions and technical corrections. Flex fuel vehicles are designed to operate on a range of ethanol and petrol blends using a single fuel tank, with engine controls adjusting automatically to fuel composition. The notification clarifies that E85/E100 is meant exclusively for specially certified vehicles and does not mandate existing vehicle owners to switch or modify their vehicles.
