Posted by Written by Naina Bhardwaj Reading Time: 3 minutes

India has proposed fuel consumption standards (FCS) for all vehicles, including light, medium, and heavy-duty motor vehicles, which are either manufactured or imported for sale in India. These norms are proposed to be implemented from April 1, 2023. The government has invited stakeholder comments for the draft policy till July 30, 2022.


India recently announced its plans to implement fuel consumption standards (FCS) for light, medium, and heavy-duty motor vehicles under various categories that are either manufactured in or imported by India. Prior to this notification, FCS compliance was only applicable to vehicles under the M1 category (motor vehicle used for the carriage of passengers, comprising not more than eight seats in addition to the driver’s seat).

As per the draft notification issued by the Ministry of Road Transport and Highways (MoRTH) on July 1, 2022, this compliance will be applicable from April 1, 2023. The draft policy notification seeks to amend Rule 115 G of the Central Motor Vehicle Rules (CMVR), 1989 to implement the proposed changes.

The government has invited comments from stakeholders within 30 days from the date of the notification, that is, till July 30.

The move, if it goes through, will expand the ambit of vehicles subject to FCS compliance. The objectives are twofold and linked – reduce pollution levels in the country and introduce more fuel-efficient vehicles to the Indian market.

What are India’s fuel consumption standards?

India’s fuel consumption standards relate to the corporate average fuel efficiency, that is, the average of the standard fuel consumption of all vehicles sold by the manufacturers in the fiscal year, and not according to the fuel consumption of an individual vehicle model.

The fuel consumption is measured under standard conditions at nationally accredited labs over the national driving cycle. 

These standards are expected to reduce fuel consumption by 22.97 million tons by 2025.

India first introduced FCS norms in 2015 and implemented them for vehicles in the M1 category from FY 2018. With the latest notification, auto makers supplying to the Indian market should note that regulators are serious about extending the standards to all categories of vehicles.  

Which categories of passenger vehicles must comply with fuel consumption standards in India?

These vehicles use petrol, diesel, liquefied petroleum gas, or compressed natural gas and are used for carriage of passengers and their luggage and comprising not more than nine seats (including driver’s seat) with a gross vehicle weight (GVW) of up to 3.5 tons.
