Flex Fuel Vehicle Market Report 2026

The flex fuel vehicle market size has grown steadily in recent years. It will grow from $77.31 billion in 2025 to $80.61 billion in 2026 at a compound annual growth rate (CAGR) of 4.3%. The growth in the historic period can be attributed to biofuel policy support, availability of ethanol blends, automotive engine adaptability, fuel cost volatility, emissions reduction initiatives.

The flex fuel vehicle market size is expected to see steady growth in the next few years. It will grow to $96.01 billion in 2030 at a compound annual growth rate (CAGR) of 4.5%. The growth in the forecast period can be attributed to higher ethanol blending mandates, renewable fuel investments, flex-fuel vehicle standardization, demand for lower emissions, energy security goals. Major trends in the forecast period include government promotion of ethanol blending, expansion of flex-fuel engine platforms, rising adoption in emerging markets, cost advantage over conventional fuels, oem focus on fuel compatibility.

The rising demand for eco-friendly vehicles is expected to drive the growth of the flex-fuel vehicle market in the coming years. Eco-friendly vehicles are designed to minimize environmental impact compared to traditional internal combustion engine vehicles and include electric, hybrid, hydrogen, and natural gas vehicles. Flex-fuel vehicle technology enables these vehicles to reduce greenhouse gas emissions, making them a more sustainable alternative to conventional gasoline-powered cars. For instance, in April 2024, according to the International Energy Agency (IEA), a France-based intergovernmental organization, global electric car sales reached nearly 14 million in 2023, accounting for 18% of all cars sold, up from 14% in 2022. Therefore, the growing demand for environmentally friendly vehicles is propelling the flex-fuel vehicle market.

Major players in the flex-fuel vehicle market are increasingly concentrating on developing modified engines featuring flex-fuel technology to enhance their market profitability. Modified engines are internal combustion engines that have been customized or altered from their original factory specifications to improve performance, power output, or other characteristics. In August 2023, Toyota Motor Corporation, a Japanese automotive manufacturer, introduced the electrified flex-fuel Innova HyCross car in India, the world's first fully ethanol-powered car equipped with a flex-fuel engine. The flex-fuel engine is a modified 2.0-liter, four-cylinder engine running on E85 fuel, a blend of 85% ethanol and 15% gasoline. The Innova HyCross flex-fuel model is anticipated to provide up to 30% better fuel economy than the standard Innova HyCross hybrid, thanks to its use of E85 fuel. Additionally, the Innova HyCross flex-fuel features a self-charging lithium-ion battery that can operate the vehicle in electric mode, offering a more environmentally friendly and fuel-efficient transportation option.

In July 2023, Molecular Energies PLC, a UK-based molecular energy company, acquired Dual Fuel Ltd. for an undisclosed sum. The acquisition is set to reinforce Molecular Energies' position in the hydrogen mobility market and bolster the development of environmentally friendly vehicles. Dual Fuel Ltd., a US-based engineering company, specializes in converting conventional gasoline-powered vehicles to run on ethanol and other alternative fuels, representing a form of flex-fuel technology.
