India has allowed E100 ethanol fuel in vehicles specifically designed by their manufacturers to operate as flex-fuel vehicles, under amendments to the Central Motor Vehicles Rules, 1989. The change does not authorize its use in all petrol-powered vehicles.

Key Takeaways

  • The amended emission provisions refer to E85 or E100, where they previously referred to E85.
  • A gross vehicle weight threshold in the relevant standards has risen from 3,000 kg to 3,500 kg.
  • The rules take effect upon publication in the Official Gazette; the source does not specify that publication date.

E100 ethanol fuel rule applies to designed vehicles

The Ministry of Road Transport and Highways amended references in multiple provisions of Rule 115, which covers vehicle emission standards, to include E100 alongside E85. E100 is fuel containing 100% ethanol, while E85 contains 85% ethanol.

Flex-fuel vehicles are designed to operate on different blends of petrol and ethanol. The notification restricts E85 or E100 use to vehicles designed by original equipment manufacturers as flex-fuel vehicles.

Weight threshold and effective date

The amendments also replace a 3,000 kg gross vehicle weight threshold with 3,500 kg in the relevant emission standards.

The government issued draft rules for public comment on April 27, 2026, and said it considered the objections and suggestions received. The final amendments come into force on the date of their publication in the Official Gazette, although that date is not specified in the available source.

The notification does not set a timetable for E100 fuel to become commercially available across India.
