Maruti Suzuki To Launch India’s First E100 Flex Fuel Car On June 5, Says Nitin Gadkari
Table of Contents
India could finally get its first flex fuel passenger car next month. Union Minister for Road Transport and Highways, Nitin Gadkari, has confirmed that Maruti Suzuki will launch a flex fuel capable vehicle during a special event in Delhi on Environment Day, June 5, 2026.
The announcement came while Gadkari was speaking about India’s push towards greener and more affordable fuel options. According to him, the move towards higher ethanol blending can reduce pollution, lower fuel costs, and cut India’s heavy dependence on crude oil imports.
Maruti E100 Flex Fuel Car Could Debut On June 5
At present, India does not have a single flex fuel four wheeler on sale. That is what makes this launch important.
The upcoming Maruti Suzuki flex fuel vehicle is expected to support very high ethanol blends, possibly up to E100, which means the car could run entirely on ethanol. Flex fuel vehicles use specially developed fuel systems, engine components, and ignition setups that allow them to work with petrol and ethanol blends without damaging the engine.
Right now, regular petrol cars in India support E20 fuel. Moving from E20 to E100 needs major changes because ethanol behaves differently compared to petrol.
Fronx Flex Fuel Was Already Shown Earlier
Last year, Suzuki displayed the flex fuel version of the Maruti Suzuki Fronx at the Japan Mobility Show 2025 in Tokyo.
That prototype was compatible with E85 fuel, which contains 85 percent ethanol and 15 percent petrol. However, Gadkari’s latest statement hints that the new vehicle could support E100 fuel instead of E85.
There is also a possibility that Maruti Suzuki may use a different model for this launch and not the Fronx. The company has not officially confirmed the vehicle name yet.
Why E100 Fuel Needs A Different Engine Setup
Ethanol absorbs moisture much faster than petrol. Because of this, vehicles running on high ethanol blends need specially designed parts inside the fuel system and engine.
Some key changes usually include:
| Component | Why It Matters |
|---|---|
| Fuel lines and tank | Prevent corrosion from ethanol |
| Injectors and fuel pump | Handle different fuel properties |
| Engine tuning | Maintain performance and efficiency |
| Ignition system | Support cleaner combustion |
Higher ethanol blends can also help lower harmful tailpipe emissions compared to regular petrol.
Gadkari Pushes For Ethanol Based Mobility
According to Gadkari, India’s shift towards ethanol based fuels can help in several ways:
- Reduce crude oil imports
- Improve energy security
- Support local ethanol production
- Lower running costs
- Reduce pollution levels
India currently imports around 87 percent of its crude oil requirement. Rising global oil prices and supply chain uncertainty have pushed the government to speed up alternative fuel adoption.
More Automakers Are Already Testing Flex Fuel Vehicles
Gadkari also revealed that around 12 manufacturers have already showcased flex fuel vehicles in India.
Some of the brands include:
- Toyota
- Tata Motors
- Mahindra
- Suzuki
Flex fuel two wheelers have already entered the market through Honda and Suzuki models. The government now wants wider adoption across scooters, cars, trucks, buses, and even tractors.
India Preparing For Higher Ethanol Blends
India has already standardised E20 petrol nationwide. The Bureau of Indian Standards has also issued specifications for future fuel blends including:
- E22
- E25
- E27
- E30
This shows that the country is preparing for the next phase of the ethanol blending roadmap.
If Maruti Suzuki launches an E100 compatible car next month, it could become a major step in India’s alternative fuel journey and open the door for more flex fuel vehicles in the coming years.

FAQ
What is Maruti Suzuki expected to launch on June 5, 2026?
Maruti Suzuki is expected to launch a flex fuel capable vehicle in Delhi on Environment Day. The report suggests it could be an E100 compatible model, but the company has not officially confirmed the exact vehicle name yet.
What does E100 mean?
E100 means a fuel blend made entirely of ethanol. A vehicle designed for E100 can run on 100 percent ethanol with the right fuel system and engine setup.
Has India sold any flex fuel four wheeler before this?
No. The report says India does not currently have a flex fuel four wheeler on sale. That is what makes this launch important.
Was the Maruti Suzuki Fronx flex fuel version shown earlier?
Yes. Suzuki showed the Fronx flex fuel version at the Japan Mobility Show 2025 in Tokyo. That prototype was said to support E85 fuel, not E100.
Why does an E100 vehicle need special parts?
Ethanol absorbs moisture more easily than petrol, so high ethanol blends need specially designed fuel lines, tank parts, injectors, fuel pumps, engine tuning, and ignition systems.
What fuel blends is India preparing for?
India has already standardised E20 petrol. The Bureau of Indian Standards has also issued specifications for E22, E25, E27, and E30 fuels.
Why is the government pushing ethanol based fuel?
The push is meant to reduce crude oil imports, improve energy security, support local ethanol production, lower running costs, and reduce pollution levels.
Which other companies have shown flex fuel vehicles?
The report says around 12 manufacturers have already showcased flex fuel vehicles in India, including Toyota, Tata Motors, Mahindra, and Suzuki.
