Hyundai Creta to Tata Punch: Flex-Fuel Innovations Shine at Auto Expo 2025

While electric vehicles dominate the future of mobility conversation, the Auto Expo 2025 showcased an alternative green solution that caught significant attention: flex-fuel vehicles. Designed to operate on a blend of petrol and ethanol, flex-fuel vehicles promise reduced fuel costs and lower emissions. Here’s a closer look at three flex-fuel-powered stars that graced the Auto Expo 2025.

Hyundai Creta Flex Fuel: A Turbocharged Marvel

Hyundai unveiled its Creta Flex Fuel, featuring a newly adapted 1.0-litre, three-cylinder turbocharged engine. Already a proven powerhouse in models like the Hyundai i20, Venue, and Kia Sonet, this engine has undergone significant upgrades to handle ethanol blends ranging from E0 to E100.

• Performance Highlights:
  • Maximum Power: 118 bhp @ 6,000 rpm
  • Peak Torque: 172 Nm @ 1,500 rpm
  • Transmission: 6-speed torque converter automatic

This flex-fuel powertrain, a first in Hyundai India’s lineup, reflects the brand’s commitment to innovative solutions for sustainable mobility. With its seamless adaptability to ethanol fuel blends, the Creta Flex Fuel is poised to set new standards in India’s flex-fuel market.

Mahindra XUV 3XO: A Versatile Performer

The Mahindra XUV 3XO Flex Fuel model made waves with its 1.2-litre, three-cylinder turbocharged engine, optimized for ethanol blends ranging from 20% to 85%. Known for its balance of power and efficiency, this engine delivers:

• Performance Highlights:
  • Maximum Power: 110 bhp @ 5,000 rpm
  • Peak Torque: 200 Nm (2,000–3,500 rpm)

This proven engine platform now offers the added advantage of ethanol compatibility, marking Mahindra’s dedication to versatile and environmentally friendly vehicles.

Tata Punch Flex Fuel: A Prototype with Promise

Tata Motors debuted the Tata Punch Flex Fuel prototype, emphasizing innovation and practicality. This compact SUV can operate on ethanol blends up to 85% (E85) and even 100% ethanol. While its exterior remains identical to its petrol variant, the significant advancements are under the hood:

• Key Mechanical Upgrades:
  • Smart Engine Control: Automatically adjusts to different ethanol blends in real time.
  • Heated Fuel Injection System: Ensures smooth starts in cold conditions.
  • High-Flow Injectors: Deliver consistent performance across ethanol fuel variations.
  • Ethanol Blend Detection: Smart sensors detect fuel composition seamlessly.
  • Advanced Emission Controls: A sophisticated exhaust after-treatment system reduces harmful gases.

Tata’s innovative engineering ensures the Punch Flex Fuel prototype is not just sustainable but also reliable and efficient.

Why Flex-Fuel Matters

Flex-fuel vehicles are emerging as a viable alternative in the transition to cleaner energy. By utilizing ethanol blends, these vehicles significantly reduce greenhouse gas emissions while decreasing dependence on fossil fuels. Furthermore, flex-fuel technology aligns with India’s push for sustainable and affordable mobility solutions.
