Hero MotoCorp and Maruti Launched Flex-Fuel Vehicles: What They Are and Can They Help You Save Money?

Hero MotoCorp and Maruti Suzuki have recently introduced flex-fuel vehicles in India, bringing the technology into the spotlight. 

With these launches grabbing attention, many consumers are wondering what exactly flex-fuel vehicles are, how they work, and whether they can actually help reduce fuel expenses. 

Hero MotoCorp and Maruti Suzuki's Latest Flex-Fuel Launches 

Hero MotoCorp launched the Splendor+ Flex Fuel and HF Deluxe Flex Fuel, making them India's first flex-fuel motorcycles in the 100cc segment. 

The motorcycles are compatible with ethanol-blended fuels ranging from E20 to E85 and have been positioned as an environmentally friendly commuting solution aimed at reducing carbon emissions while maintaining affordability. 

Maruti Suzuki also entered the segment by unveiling the Wagon R Flex Fuel. The vehicle can run on ethanol-petrol blends ranging from E20 to E100, making it India's first flex-fuel passenger car. 

The launch aligns with the government's broader objective of reducing crude oil imports, promoting cleaner fuels, and supporting domestic ethanol production. 

What Is a Flex-Fuel Vehicle? 

A flex-fuel vehicle (FFV) is designed to run on petrol, ethanol, or a blend of both. 

Unlike conventional petrol vehicles, which are typically compatible with E20 fuel, flex-fuel vehicles can safely operate on much higher ethanol blends such as E85 and even E100. 

For instance, E20 contains 20% ethanol, E85 contains up to 85% ethanol, and E100 is almost entirely ethanol-based fuel.  

The vehicle automatically adjusts its engine settings depending on the ethanol concentration in the fuel tank, allowing seamless operation across different fuel blends. 

How Are Flex-Fuel Vehicles Different from Regular Petrol Vehicles? 

The key difference lies in fuel compatibility and engine design. 

Most petrol vehicles sold today are engineered to handle E20 fuel. However, higher ethanol concentrations can damage conventional fuel systems over time. 

To handle higher ethanol blends, flex-fuel vehicles use specialised components, including ethanol-resistant fuel systems, modified injectors, dedicated ECUs, and sensors that automatically adjust engine performance based on the ethanol content in the fuel. 

Why Is the Government Promoting Flex-Fuel Vehicles? 

The government's push towards ethanol-based mobility is driven by three key objectives: 

Reducing Oil Imports 

India spends billions of dollars annually on crude oil imports. Increasing ethanol usage can help lower this dependence and improve energy security. 

Lowering Emissions 

Ethanol burns cleaner than conventional petrol and can contribute to lower vehicle emissions. 

Supporting Farmers 

Ethanol production creates demand for agricultural products such as sugarcane and maize, potentially benefiting farmers and rural industries. 

Can Flex-Fuel Vehicles Help You Save Money? 

Ethanol is generally cheaper to produce than petrol. If ethanol-based fuels such as E85 are priced significantly lower than petrol, consumers could benefit from lower fuel costs. 

However, there is an important trade-off. 

Ethanol contains approximately 30-35% less energy per litre than petrol. As a result, vehicles typically consume more fuel to cover the same distance when running on high-ethanol blends. 

Whether a flex-fuel vehicle reduces running costs depends on several factors, including ethanol prices relative to petrol, government taxation policies, vehicle fuel efficiency, and the availability of ethanol fuel stations. As a result, actual savings may vary based on fuel pricing and individual usage patterns. 

Is India Ready for E85 and E100 Fuel? 

While India has successfully rolled out E20 fuel nationwide, expanding to E85 and E100 presents additional challenges.  

India plans to roll out E85 fuel at 500 petrol pumps across Delhi-NCR, Mumbai, Pune, and Nagpur by the end of 2026. 

Furthermore, the Indian government plans to establish around 5,000 E100 fuel stations across the country in the next 2 years. However, fuel availability remains one of the biggest hurdles to widespread adoption.

Conclusion 

The recent launches by Hero MotoCorp and Maruti Suzuki have brought flex-fuel technology into mainstream conversation. These vehicles can run on significantly higher ethanol blends than conventional petrol vehicles and form part of India's broader effort to reduce oil imports and promote cleaner fuels. 

While the technology has the potential to lower fuel costs under favourable pricing conditions, the extent of consumer savings will depend on ethanol prices, vehicle efficiency, and the availability of higher ethanol blends across the country.
