Hiroya Ueda, Chief Engineer for Motorcycle and Power Products Operations at Honda Motor Co, recently underlined the transformative potential of flex-fuel motorcycles in India. He highlighted the environmental and economic opportunities presented by ethanol-based fuels positioning flex-fuel vehicles as a cornerstone of Honda’s multi-path strategy for a sustainable future.
Why Flex-Fuel Matters?
Flex-fuel technology enables vehicles to run on ethanol-gasoline blends offering significant reductions in carbon emissions and pollutants. Globally, biofuels such as ethanol account for 3% of energy consumption in the transportation sector with major production hubs in the United States and Brazil. While challenges remain in terms of cost and sustainability, advancements in technology and supportive policies continue to drive adoption.
For India, a country with a vast agricultural base and rising demand for sustainable mobility solutions, ethanol-based biofuels offer a dual advantage. They can reduce dependence on imported oil while creating a domestic market for surplus sugarcane production, which forms the primary raw material for ethanol.
Ueda highlighted the environmental benefits of ethanol blends. The production process for biofuels emits up to 80% less CO₂ compared to gasoline, and pollutants such as carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM) can be effectively controlled using advanced fuel injection systems. These benefits align with India’s ambitions to combat air pollution and reduce greenhouse gas emissions under its National Bio-Energy Mission.
Performance Considerations
Honda’s global experience with flex-fuel motorcycles has demonstrated improvements in engine performance and fuel efficiency. While ethanol has a lower energy density than gasoline, necessitating greater consumption to generate equivalent horsepower, Honda has developed advanced technologies to address this drawback.
Since 2009, Honda has improved the fuel efficiency of its flex-fuel motorcycles by more than 20%. Ethanol’s high octane rating and superior cooling properties have also enabled a 5% increase in engine power compared to gasoline. These innovations not only maintain but enhance the performance capabilities of motorcycles, making them a viable option for urban commuters and long-distance riders in India.
Adapting Flex-Fuel To India’s Climate Challenges
One of the challenges of ethanol is its higher ignition point, which can impede engine performance in colder climates. In regions where temperatures dip below 5°C, starting engines with high ethanol concentrations becomes difficult. Based on its experience in Brazil, Honda identified E85—a blend of 85% ethanol and 15% gasoline—as the optimal concentration for India, balancing performance with usability in diverse climatic conditions. Notably, this is not much of a problem for the Indian consumer.
In October 2024, Honda launched its first flex-fuel motorcycle in India, a significant milestone for the brand and the industry. The model, introduced in the 360cc segment, is also the first flex-fuel product available across Honda’s extensive pan-India dealership network.
Challenges
While the potential of flex-fuel motorcycles is promising, several challenges remain. Building the necessary infrastructure to produce, distribute, and retail ethanol at scale requires significant investment and policy support. Additionally, raising consumer awareness about the benefits of flex-fuel vehicles and addressing initial price sensitivities will be crucial for mass adoption.
Honda’s strategy of leveraging its global expertise and localising solutions for India positions it well to navigate these challenges. However, collaboration with policymakers, agricultural stakeholders, and fuel distributors will be essential to fully realise the potential of flex-fuel technology in the country. By leveraging ethanol’s environmental advantages and addressing performance challenges through technological innovation, Honda is setting a benchmark for the industry.
