Advancements in Hybrid Flex-Fuel Technology: Automakers are integrating hybrid technology with flex-fuel engines, creating vehicles that maximize fuel efficiency and reduce carbon emissions. Hybrid FFVs are expected to gain traction as consumers demand eco-friendly alternatives with extended driving ranges.
Growth in Biofuel Infrastructure: Increased investment in ethanol production and distribution networks is making flex-fuel adoption more viable. Fuel stations worldwide are expanding ethanol pump availability, supporting consumer confidence in flex-fuel vehicle purchases.
Rise in Second-Generation Ethanol Production: Innovations in biofuel production are shifting towards second-generation ethanol, which is derived from agricultural waste and non-food sources. This trend reduces concerns over food crop dependency while enhancing the sustainability of ethanol as an alternative fuel.
Automaker Commitments to Carbon Neutrality: Leading car manufacturers are prioritizing alternative fuel technologies, including FFVs, to meet their carbon neutrality targets. Many companies are developing more efficient engines and flexible fuel systems to align with global sustainability goals.
Government Policies and Incentives: Supportive government policies, tax incentives, and ethanol blending mandates are accelerating FFV adoption. Many countries are implementing regulatory frameworks that encourage biofuel production and require automakers to produce flex-fuel-compatible vehicles.
Rising Consumer Demand for Eco-Friendly Vehicles: As climate concerns grow, consumers are actively seeking fuel-efficient and lower-emission vehicles. FFVs provide a cost-effective and environmentally friendly alternative to traditional gasoline-powered cars, driving market growth.
Increasing Biofuel Production: The global biofuel industry is expanding, ensuring a steady supply of ethanol for flex-fuel vehicles. Advances in refining technology and biofuel policies are making ethanol production more sustainable and cost-effective.
Cost Benefits of Ethanol Fuel: Ethanol is often cheaper than gasoline, making FFVs an attractive option for cost-conscious consumers. With fluctuating fuel prices, the affordability of ethanol-based fuel is a key driver in the increasing adoption of flex-fuel vehicles.
Limited Ethanol Fuel Infrastructure: Despite growing investments, ethanol fueling stations remain limited in several regions, restricting widespread adoption of FFVs. The lack of adequate infrastructure makes consumers hesitant to invest in flex-fuel vehicles, especially in markets where ethanol fuel availability is inconsistent.

As car owners flag concerns on ethanol-blended petrol’s impact on older engines, Govt says fears ‘largely unfounded’ (Indian Express)
Govt says 20% ethanol blended petrol doesn't have any negative impact on older vehicles (Economic Times)

Excerpt from Indian Express: The Ministry of Petroleum and Natural Gas (MoPNG), however, has termed most such concerns as “largely unfounded” and not backed by “scientific evidence or expert analysis”.

“…the narrative that #EthanolBlending in Petrol is harming vehicles or causing undue hardship to consumers is not based on real facts and lacks technical foundation. Ethanol blending is a forward-looking, scientifically supported, and environmentally responsible measure that brings multi-dimensional benefits to the nation,” the MoPNG said in a detailed social media post on Monday. For India, which is the world’s third-largest consumer of crude oil and depends on imports to meet over 85 per cent of its requirement of the commodity, increasing the use of biofuels is a key tool towards two ends—reducing dependency on energy imports and limiting the carbon footprint of the country’s rapidly growing energy use.

While newer cars, particularly those sold since 2023, are understood to be ready for E20 fuel, engines of cars made before that have not been specifically tuned for such blended fuel, and could be at a disadvantage in the long-term. An auto industry executive said that corrosion in the engine is of particular concern, which could be even more pronounced in the case of two wheelers. The executive explained that the calorific value of ethanol blended fuel is higher than gasoline, which means that more fuel is burnt for similar performance, which brings down the fuel economy of the vehicle.

These concerns have given way to several consumers questioning its impact on the longevity of their vehicles, while also flagging the opacity at petrol pumps regarding the type of fuel they were getting, where no clear communication exists about the blend levels. They are also questioning why such blended fuel is not being made available at a discounted rate than unblended petrol.

The MoPNG acknowledged the drop in fuel economy due to the use of E20 fuel—blend of 80 parts petrol and 20 parts ethanol—but said that the decrease was only “marginal”.

...

“Ethanol, being lower in energy density than petrol, results in a marginal decrease in mileage, estimated at 1–2% for four-wheelers designed for #E10 and calibrated for #E20, and around 3–6% in others. This marginal drop in efficiency can be further minimized through improved engine tuning and use of E20-compatible materials, which leading automobile manufacturers have already adopted. In fact, the Society of Indian Automobile Manufacturers (SIAM) has confirmed that E20-compliant vehicles with upgraded components began rolling out from April 2023. Thus, the allegation that E20 leads to drastic drop in fuel efficiency is factually incorrect,” the MoPNG said in its post on social media platform X.

On the effect of engine corrosion, the ministry said that safety standards for E20, including corrosion inhibitors and compatible fuel system materials, are well established through the Bureau of Indian Standards (BIS) specifications and Automotive Industry Standards. “Replacement of some rubber parts/ gaskets could be advised in certain older vehicles after prolonged use of say 20,000 to 30,000 kms. This replacement is inexpensive and easily done during regular servicing of the vehicle,” it said.

The ministry also said that international studies on the effect of using ethanol-petrol blends on mechanical, energy, and environmental performance every 10,000 km during their first 100,000 km showed “no significant differences” in power and torque, and fuel consumption levels. READ MORE

Excerpt from Economic Times: The government assures that E20 petrol poses no significant harm to older vehicles, dismissing concerns as unfounded. Studies indicate no major performance issues or wear-and-tear with E20 use in legacy vehicles. While a slight mileage decrease may occur, it can be minimized with engine tuning. The transition to E20 is a phased, well-communicated approach, benefiting the environment and economy. READ MORE
