Why is this in news?
- With E20 fuel (20% ethanol–petrol blend) now mandatory across India, Toyota Kirloskar Motor’s country head Vikram Gulati stated that the next policy priority should be the promotion of flex fuel vehicles (FFVs).
- He argued that global experience shows countries move to flex fuels after stabilising initial ethanol blends, and that India is now at that juncture.
- The discussion is significant for India’s goals of reducing oil import dependence, supporting the ethanol economy, and decarbonising transport.

What are flex fuel vehicles (FFVs)?
- FFVs can run on any blend of petrol and ethanol, from E20 to E85 or even E100, depending on design.
- The engine, fuel system, and electronic controls are adapted to handle higher ethanol concentrations.
- Ethanol has:
- higher octane number
- lower greenhouse gas emissions
- lower cost in countries with strong biofuel sectors
India’s current stage: E20 rollout
- India mandated E20-compatible vehicles starting 2023; nationwide availability is expanding.
- E20 reduces emissions and cuts fuel import bills, but requires vehicle & fuel system modifications.
- Gulati notes that once a country successfully reaches this stage, global trends indicate transition to FFVs.
Why push for flex fuels now?
1. Global evidence
- Countries like Brazil moved to FFVs once ethanol blends stabilised.
- Brazil mandates that E100 (ethanol) is cheaper than petrol by around 30%, driving consumer uptake.
2. Consumer economics
- Pricing parity between E20 and petrol is insufficient; FFVs allow higher ethanol use, reducing running cost.
- Flex fuels become viable only when ethanol is consistently cheaper than petrol at retail level.
3. Industry readiness
- Automotive firms (Toyota, Honda, others) are aligned that the next disruption in India will be FFVs, not merely higher ethanol blends.
- Small EVs face cost issues; hybrid EVs and FFVs can bridge the transition.
4. Technology maturity
- Legacy vehicles risk compatibility issues as ethanol percentages rise.
- FFVs reduce uncertainty and avoid frequent re-testing/re-homologation as blends evolve.
Key challenges highlighted
1. Legacy vehicles and compatibility
- Increasing ethanol blends affect older vehicles’ materials, seals, pumps, and combustion characteristics.
- Without FFVs, retrofitting or re-homologation costs rise.
2. Taxation and GST issues
- India taxes vehicles primarily based on size, not fuel technology.
- Better taxation differentiation is needed to make FFVs competitive.
3. Pricing regulation
- For mass adoption, ethanol blends must be consistently cheaper than petrol at the pump.
- The Brazilian model succeeded because the government ensured favourable pricing.
4. Need for policy incentives
- Without targeted GST rationalisation, FFVs may remain niche.
- Stakeholders want a clear roadmap similar to the push given to EVs.
Why flex fuels matter for India ?
Energy security
- India imports ~85% of its crude oil.
- Scaling ethanol helps cut import bills and diversifies fuel sources.
Farmer income & rural economy
- Ethanol is produced from sugarcane, grains, and agri-residues.
- Higher ethanol demand creates predictable markets for farmers.
Cleaner combustion
- Ethanol has lower CO₂ emissions and particulate output.
- Supports India’s climate commitments under NDCs.
Industrial diversification
- Encourages investment in:
- first-generation ethanol
- second-generation ethanol (agri-waste)
- biomass refineries
Bridge technology
- FFVs act as a transition between ICE engines and electric mobility, suited to India’s current infrastructure realities.
What the government needs to consider going forward ?
1. Differential fuel pricing
- Guarantee ethanol blends (E85/E100) at a significant discount to petrol.
2. Taxation framework
- GST rationalisation for FFVs.
- Reduced GST for flex fuel-compatible components and hybrids.
3. National FFV roadmap
- Clear timelines for:
- increasing blend levels
- phasing in FFV norms for OEMs
- developing high-ethanol fueling infrastructure
4. Consumer awareness
- Highlight lower running costs and environmental benefits.
5. Coordination between ministries
- Petroleum, Transport, Agriculture, and Environment must align on pricing, supply, and infrastructure.
