Tata Motors says it could be ready with its first flex-fuel passenger vehicle by the end of 2026 or early 2027, as India moves towards establishing a regulatory framework for higher ethanol-blended fuels. The statement was made by Tata Motors Passenger Vehicles MD and CEO Shailesh Chandra during the company’s Q4 and FY2026 earnings interaction with the media.
“As far as we are concerned, we are very comfortable in terms of technology readiness. By the end of this year or early next year, we should also be ready with our flex-fuel product – at least one product,” Chandra said.

Tata says it is ready for higher ethanol blends
Speaking during the media interaction, Chandra said the recent government notification is aimed at creating a category definition for flex-fuel vehicles capable of operating on varying ethanol blends. Chandra also stated that Tata Motors’ vehicles have been E20-compliant since 2023, while discussions regarding higher ethanol blends are currently taking place with the government through SIAM.
The government recently proposed amendments to the Central Motor Vehicles Rules to formally include higher ethanol-blended fuels such as E85 and E100. The draft proposal has currently been opened for public comments.
Tata Punch flex-fuel : What we know so far
As per our earlier report, Mohan Savarkar, Chief Product Officer and Vice President at Tata Motors Passenger Vehicles, had told us that the Punch is likely to become the company’s first flex-fuel passenger vehicle once the government finalises regulations around higher ethanol blends.
Tata Motors had earlier showcased a flex-fuel version of the Tata Punch at the Bharat Mobility Global Expo 2025, where the Punch was displayed with four different powertrain options – petrol, CNG, electric and flex fuel.
The flex-fuel Punch used the same 1.2-litre, three-cylinder naturally aspirated petrol engine as the standard model, but featured updates to the ECU, fuel-injection system and exhaust after-treatment system to detect and adapt to varying ethanol blends. The showcased model was compatible with up to E85 fuel, meaning it can run on petrol blended with up to 85 percent ethanol.
The Punch is already sold with petrol, CNG and electric powertrain options, and a flex-fuel version would further expand Tata Motors’ multi-powertrain strategy. Other manufacturers, including Hyundai, Maruti Suzuki and Toyota, have also previously showcased flex-fuel prototypes in India.
