Mahindra & Mahindra is taking significant steps to future-proof its vehicle lineup by developing advanced flex-fuel engines. These new powerplants will be designed to run on petrol blended with up to 30% ethanol (E30) and potentially even higher concentrations, positioning the automaker ahead of upcoming government regulations.
This initiative runs parallel to the development of Mahindra’s new modular NU-IQ platform, a versatile architecture designed to support various powertrain options and body styles for its next generation of SUVs. By focusing on both platform flexibility and engine adaptability, Mahindra is building a resilient product strategy for the years ahead.
Why is Mahindra Focusing on Flex-Fuel Technology?
The push toward flex-fuel engines is a direct response to the Indian government’s roadmap for increasing the use of ethanol in petrol. With a target of introducing E30 fuel by 2030, automakers must re-engineer their engines to ensure compatibility and performance.
Running on higher ethanol blends isn’t as simple as just pouring the new fuel into the tank. Ethanol has different chemical properties than gasoline, requiring significant modifications to the engine and fuel system. Key upgrades include:
- Ethanol Content Sensors: These are crucial for real-time monitoring of the ethanol concentration in the fuel.
- Fuel System Enhancements: Components like the fuel rail and injectors need heaters to ensure smooth cold starts, as ethanol behaves differently in low temperatures.
By proactively developing these technologies, Mahindra aims to be fully prepared when the new fuel standards are implemented nationwide.
Indian Automakers Embrace Flex-Fuel Vehicles
Mahindra is not alone in exploring flex-fuel technology. The recent Auto Expo 2025 showcased a strong industry-wide trend, with several major manufacturers displaying their own flex-fuel prototypes. Although specific launch timelines for most of these vehicles remain unconfirmed, the message is clear: the Indian auto industry is gearing up for an ethanol-blended future.
Notable flex-fuel models displayed include:
- Hyundai Creta 1.0 Flex Fuel
- Tata Punch (E85 compatible)
- Maruti Wagon R Flex Fuel
Toyota took a unique approach by presenting a hybrid powertrain for the Innova Hycross capable of running on E20 and higher-rated fuels, combining the benefits of both hybrid and flex-fuel technologies. This collective push signals a major shift in the market, with automakers investing heavily to align with India’s long-term environmental and energy goals.
