Maruti Suzuki has officially launched the Wagon R Flex Fuel in India on June 4, 2026, a day before World Environment Day, making it the country’s first flex-fuel passenger car. The launch happened in New Delhi in the presence of Union Ministers Nitin Gadkari and Hardeep Singh Puri. Prices are yet to be announced, but this is a real production car, not a concept.

What Is a Flex-Fuel Car and Why Does It Matter?
Most cars in India today run on petrol or CNG. A flex-fuel vehicle (FFV) can run on any blend of ethanol and petrol, from E20 (20% ethanol) all the way up to E100 (pure ethanol). The engine detects the ethanol content in the fuel and adjusts itself automatically.
India currently mandates E20 blending at most pumps. Pure ethanol (E85 or E100) fuel is available at roughly 50 to 100 locations right now, mostly in Delhi-NCR and along the Mumbai-Nagpur corridor. The government has set a target of 5,000 ethanol dispensing stations across the country by end of 2027. So yes, the Wagon R can technically run on E100, but you will not find that fuel everywhere just yet.
Wagon R Flex Fuel: Engine and Key Technical Details
The Wagon R Flex Fuel uses Maruti’s K12N 1.2-litre four-cylinder petrol engine, modified for ethanol compatibility. Changes include upgraded fuel injectors and fuel pump, new fuel lines, a freshly calibrated ECU, and an ethanol sensor that detects the concentration of ethanol in the fuel and adjusts engine parameters on the fly.
Maruti has not officially disclosed power output or mileage figures yet. Expect those to come with pricing and variant details.
| Specification | Details |
|---|---|
| Engine | K12N, 1.2-litre, 4-cylinder |
| Fuel Compatibility | E20 to E100 (Ethanol-Petrol blend) |
| ECU | Advanced calibration for ethanol detection |
| Fuel Injectors | Upgraded for ethanol |
| Fuel Lines | Ethanol-resistant new lines |
| Transmission | 5-speed Manual (AMT expected) |
| Body Type | Hatchback |
| Seating | 5 |
Availability and Who Can Buy It
Here is the catch. The Wagon R Flex Fuel has been made available for the commercial sector initially, not private buyers. Think fleet operators, cab aggregators, and commercial use cases. Private ownership may follow as ethanol fuel infrastructure scales up. Maruti has been measured about this, and rightly so.
Rahul Bharti, Senior Executive Officer at Maruti Suzuki, acknowledged during the company’s quarterly earnings call that flex-fuel volumes will remain minimal initially due to limited E100 availability at fuel stations. He projected the segment could take 5 to 10 years to become meaningful in volume terms.
So if you were hoping to park one in your home garage this month, you will need to wait a bit longer.
Expected Price
Official pricing has not been declared. Based on industry estimates circulating ahead of the launch:
| Variant | Expected Price (Ex-Showroom) |
|---|---|
| Base | Around Rs. 8.00 lakh |
| Top | Around Rs. 8.50 to 9.50 lakh |
These are estimates. Final prices will be confirmed by Maruti Suzuki officially. The production cost premium over a standard petrol Wagon R is pegged at Rs. 50,000 to 70,000, which gives a rough sense of where pricing might land.
What the Government Says
Road Transport Minister Nitin Gadkari called this a direct step toward reducing crude oil imports and strengthening the rural economy, since ethanol is produced from sugarcane, rice, and other farm produce. Petroleum Minister Hardeep Singh Puri added that this fits into India’s broader goal of turning farmers from food providers into energy providers, his phrase “annadatas to urjadatas” sums it up well.
Flex-fuel vehicles reduce India’s dependence on imported crude oil. That is the bottom line. Less crude oil imported means more foreign exchange saved, which feeds back into the broader economy. Whether it translates into cheaper running costs for you as a buyer depends entirely on ethanol pricing parity with petrol, which is still a work in progress.
Why the Wagon R Was the Right Pick
Maruti did not choose the Wagon R by accident. The Wagon R became the best-selling Maruti car in India in 2024. It already has a strong association with alternate fuels. The car has been available in CNG and LPG variants for years, so the flex-fuel version is a natural extension of that legacy rather than a dramatic departure.
The production version looks identical to the standard Wagon R, apart from green badging. No dramatic redesign, no futuristic styling. Just the same practical, tall-boy hatchback that millions of Indian families already know.
The Real-World Bottleneck: Ethanol Infrastructure
Honestly, this is the part that will decide whether the Wagon R Flex Fuel stays a headline or becomes a meaningful product. E85 fuel is currently dispensed at only 50 to 100 locations across Delhi-NCR and the Mumbai-Nagpur corridor. Running on higher ethanol blends outside these corridors is simply not possible today.
If the government’s plan of 5,000 ethanol stations by 2027 comes through, the math changes completely. Ethanol is cheaper than petrol on a per-litre basis, and it burns cleaner. For high-mileage commercial users especially, the running cost advantage on E85 or E100 would be substantial once supply is sorted.
Should You Care Right Now?
For private buyers, not immediately. But this launch matters because someone had to go first, and Maruti has done that. The Wagon R Flex Fuel sets a template that other carmakers will now have to respond to. Toyota and Tata Motors have shown flex-fuel prototypes before, but Maruti Suzuki is the first carmaker to put a flex-fuel vehicle into production in India.
For readers who follow alternative fuel tech, follow ethanol fuel availability in your city over the next 12 to 24 months. That will be the real signal for when this becomes a car worth buying.
