India’s automotive market is shifting toward cleaner and locally produced fuels. Flex fuel vehicles in India are designed to run on petrol with varying amounts of ethanol, giving drivers more fuel options and helping to accelerate adoption of biofuels more widely.

As of 2026, the Maruti Suzuki Wagon R Bioflex is the first flex-fuel passenger car to be manufactured and sold to private consumers in India. Other automakers, including Toyota, Tata, Hyundai and Kia, have shown flex-fuel prototypes or concepts, suggesting more choices are likely to come in the next few years.

Quick Summary

• Flex-fuel vehicles are able to run on petrol-ethanol blends.

• The only flex-fuel production car available in India right now is the Maruti Suzuki Wagon R Bioflex.

• The Wagon R Bioflex is priced at ₹7.24 lakh ex-showroom.

• Tata, Toyota, Hyundai, and Kia have showcased flex-fuel vehicles or concepts.

• Buyers should check ethanol fuel availability before choosing a flex-fuel vehicle.

What Makes a Car Flex-Fuel Compatible?

Flex-fuel vehicles (FFV) are capable of operating on different combinations of ethanol and petrol. An FFV has modified engine management and fuel-system parts that allow for different ethanol levels, unlike a typical petrol vehicle that has been designed to a specific fuel specification.

Take the Maruti Suzuki Wagon R Bioflex, for instance, whose ECU tuning is capable of handling ethanol blends from E20 onwards. Maruti claims that the vehicle is compatible with E100 fuel, but for now its homologation is based on E85 as per the applicable regulations.

This means buyers can have more fuel flexibility as higher ethanol blends become more broadly available.

Which Flex Fuel Cars Can You Buy in India Right Now?

Currently, the Maruti Suzuki Wagon R Bioflex is the only flex-fuel passenger car in production that is available for Indian buyers.

The Bioflex is built on the Wagon R ZXi+ 1.2 petrol-manual, and the car comes with a modified 1.2-litre four-cylinder petrol engine which churns out about 91hp and 114Nm. It is developed for higher ethanol blends and is priced at ₹7.24 lakh, ex-showroom.

That makes it an important starting point for anyone looking for the best flex fuel cars that are available in India at the moment.

Practical Comparison

Prices and availability for prototypes/concepts are not confirmed.

Which Maruti Car Runs on Flex Fuel?

Amongst Maruti passenger vehicles, only the Wagon R is available with a dedicated flex-fuel powertrain.

The Wagon R Bioflex comes with the 1.2-litre petrol engine and is sold in a high-spec setup with a manual gearbox. This is Maruti Suzuki’s first passenger vehicle with a flex-fuel engine to be made in India. It is priced at ₹7.24 lakh, ex-showroom.

It is worth recalling that a standard E20-compatible petrol car is not automatically a flex-fuel vehicle. FFVs will require some hardware and software modifications to safely accommodate higher ethanol levels.

What Are the Upcoming Flex-Fuel Cars in India?

The list of upcoming flex-fuel cars in India is growing, although manufacturers have not confirmed launch dates for many of them.

Tata Motors has said it could have its first flex-fuel passenger vehicle ready by late 2026 or early 2027. One of the models that comes in this development is the Punch flex-fuel concept that had been showcased at the Bharat Mobility Global Expo 2025.

Toyota had earlier displayed a prototype of the Innova Hycross flex-fuel hybrid. The car is powered by a 2.0L gasoline engine paired with an electric motor and has had its fuel system and engine hardware modified to run on higher ethanol blends.

Hyundai also showed a flex-fuel Creta, while Kia recently showed a flex-fuel concept called the Syros. Kia has not said when it will go into production.

Hence, it becomes necessary to distinguish between models that are truly available for sale and those that are just showcased when you look for flex fuel cars in India in 2026.

What Should You Check Before Buying an Ethanol Fuel Car?

When you are buying any of these vehicles, don’t just think about the flex fuel car price in India.

Check to see if your area has higher ethanol blends like E85. Fuel infrastructure is still being built, so availability can be inconsistent. You should also compare expected running costs, fuel economy, warranty, and servicing requirements.

Conclusion

The flex fuel car market in India is still emerging, but 2026 is an important milestone with the introduction of the Waggon R Bioflex. Tata, Toyota, Hyundai and Kia have also shown technology that could boost the range of ethanol fuel cars in India.

The trick for buyers, however, is to differentiate between production models and prototypes while verifying availability of fuel and ownership costs. As the alternative-fuel market develops in India, AutoRaftar is a good place to start when checking out new cars.
