India's flex-fuel push is building fast, with five strong candidates expected to follow the Wagon R into production.
Most models on the list support up to E85, while the Tata Punch and Hyundai Creta go even further with full E100 capability.
India's flex-fuel story did not begin and end with the Maruti Suzuki Wagon R. The carmaker recently unveiled the Wagon R Flex Fuel more than three and a half years after debuting it as a prototype, and the production version supports ethanol-blended petrol ranging from E20 all the way to E100. That unveiling has understandably prompted the question of what else is coming, and there is no shortage of credible answers.
Maruti Suzuki Fronx Flex Fuel Concept Already Shown
Back in October 2025, Maruti Suzuki showcased the Fronx Flex Fuel concept at the Japan Mobility Show.
Like the Wagon R's production version, the Fronx's flex-fuel variant is stated to support E85. It uses a modified version of the 1.2-litre petrol engine already found under the bonnet of the subcompact SUV. Exact powertrain details are expected to be confirmed closer to a potential launch.
Toyota Corolla Has Been Running Flex-Fuel on Indian Roads
The Toyota Corolla Altis Hybrid may actually be the most road-proven flex-fuel vehicle in India right now, even if it has not been made available to the general public.
Union Minister of Road Transport and Highways Nitin Gadkari has been using one as part of Toyota's pilot project on flex-fuel strong-hybrid vehicles. The powertrain pairs a 1.8-litre petrol engine with an electric motor and a CVT.
Toyota also offers the Corolla Altis with a 2-litre Dual VVT petrol engine with no hybrid technology, and that unit too can run on both petrol and ethanol, mated to a CVT.
Toyota Innova Hycross Prototype Runs on E85
Another Toyota that is well placed for a flex-fuel launch is the Innova Hycross. A prototype was unveiled by Nitin Gadkari in 2023 and uses the same 2-litre strong-hybrid powertrain found in the standard MPV, adapted to run on an ethanol blend of up to 85 per cent, with the remaining 15 per cent being petrol.
Given the Innova's strong standing in the Indian market, a production version would almost certainly find a ready audience.
Hyundai Creta Flex Fuel Can Run on Pure Ethanol
Hyundai brought the Creta Flex Fuel to India at the Bharat Mobility Global Expo 2025. The same model is already on sale in South American markets where higher ethanol blends are more prevalent.
For India, the Creta Flex Fuel uses the familiar 1-litre turbo-petrol engine that produces 120 PS and 172 Nm, the same unit found in the Venue and i20 here.
Notably, it has been modified to support a full 100 per cent ethanol blend, eliminating petrol dependence entirely. The engine is paired with a 6-speed torque converter automatic.
Tata Punch Flex Fuel Targets Full Ethanol Compatibility
Tata Motors also unveiled its first flex-fuel model at the same expo. The Punch Flex Fuel stands out for its E100 capability, going further than most of its rivals on this list. It uses the existing 1.2-litre petrol engine that produces 88 PS and 115 Nm, and is offered with both a 5-speed manual and a 5-speed AMT.
The standard Punch already offers a CNG option alongside petrol, making the brand's willingness to explore alternative fuel paths quite clear.
A Shared Direction Across Carmakers
What is particularly interesting about this list is how it spans segments, brands, and powertrain philosophies. Whether it is a mass-market hatchback, a popular SUV, or a family MPV, flex-fuel compatibility is clearly no longer a fringe consideration.
India's ethanol blending programme has been progressing steadily, and these five vehicles suggest that the industry is positioning itself to keep pace with that ambition.
