Tata Motors has taken a bold step forward in diversifying its lineup by showcasing a flex fuel version of the Tata Punch at the Auto Expo 2025. With this addition, Tata aims to cater to India’s growing need for sustainable and versatile mobility solutions. The Punch flex fuel, compatible with up to 85% ethanol (E85), marks the company’s intent to prepare for the future as India advances toward higher ethanol fuel blends.

Flex Fuel
The Tata Punch flex fuel uses the same 1.2-litre, 3-cylinder naturally aspirated (NA) engine as the standard petrol model but incorporates significant upgrades. These include software updates to the engine control unit (ECU), enhanced fuel injectors, and modifications to the exhaust after-treatment system. These upgrades enable the Punch to automatically detect and adapt to different ethanol-petrol blends, ensuring optimal performance and efficiency regardless of the ethanol concentration.
Mohan Savarkar, chief product officer and vice president of Tata Motors Passenger Vehicles, stated that the Punch flex fuel is the brand’s first product designed for E85 compatibility. He added that the timeline for widespread adoption would depend on the government’s rollout of E85 fuel, but Tata is determined to stay ahead of the curve.
Supporting Ethanol Adoption
India has been gradually introducing ethanol-blended fuels, with E20 (20% ethanol) rolling out in phases since 2023 and pan-India coverage expected by 2025. While E85-blended fuel is not yet available nationwide, Tata’s proactive approach showcases its readiness for future regulatory and environmental demands. The Punch flex fuel reflects a broader shift toward alternative fuels that can reduce reliance on conventional petrol and cut greenhouse gas emissions.
Flex fuel is particularly appealing because it aligns with India’s push for cleaner and greener transportation solutions. Ethanol, derived from renewable sources such as sugarcane and agricultural waste, is not only more sustainable but also contributes to reduced emissions compared to traditional fossil fuels.
Competitive Landscape
At the Auto Expo 2025, Tata Motors wasn’t the only automaker to showcase flex fuel options. Hyundai revealed a flex fuel version of the Creta, while Maruti Suzuki and Toyota had earlier presented prototypes of flex fuel vehicles. These developments highlight a collective industry move toward meeting stricter emission norms and providing more sustainable options for Indian consumers.
Tata Motors also displayed flex fuel technology for its small commercial vehicles, signaling its intent to make this technology more widespread across different segments. As more automakers join the flex fuel race, this technology is poised to play a significant role in the automotive industry’s transition toward cleaner energy.
The Punch Advantage
The Tata Punch has already gained popularity for its robust design, compact dimensions, and practicality. With the addition of a flex fuel variant, Tata is making the Punch even more versatile. Offering powertrain options that include petrol, CNG, electric, and now flex fuel, the Punch stands out as one of the most diverse and future-ready compact SUVs in India.
By making the Punch flex fuel-compatible, Tata Motors is not just preparing for future regulations but also giving customers a choice to opt for a cleaner and more sustainable fuel option. As ethanol-blended fuel becomes more accessible, the Punch flex fuel has the potential to become a game-changer in India’s growing SUV market.
