The 2025 Bharat Mobility Expo serves as an essential platform for showcasing the future of transportation, and this year, flex-fuel technology takes center stage. With a pressing need for sustainable and innovative solutions to address environmental challenges, flexible fuel vehicles (FFVs) are leading the charge. The expo highlights how these vehicles, capable of running on various fuel blends, can significantly reduce carbon emissions and dependency on fossil fuels.
What is Flex Fuel?
Flex fuel, also known as flexible fuel, is a type of vehicle engine that can run on multiple fuel types, typically a blend of gasoline and ethanol or methanol. The most common type of flex fuel vehicle (FFV) can use up to 85% ethanol (E85) and the remainder being gasoline.
This technology offers several benefits, including environmental advantages as ethanol and methanol have lower carbon emissions compared to traditional gasoline. It also provides economic benefits, by supporting local agriculture and reducing reliance on non-renewable fuels.
Hyundai Creta Flex fuel
Hyundai launched its new Creta Flex Fuel at the Auto Expo 2025, and that marked its effort towards sustainable mobility. The Innovative SUV features a three-cylinder engine of 1.0 liters, generating 118 bhp and 172 Nm of torque. Coupled with a six-speed smooth automatic transmission, this variant of Creta is capable of running on various blends of fuel, the maximum of E100 being pure ethanol. That just adds to the versatility of the Creta, and this would enhance its lineup to meet the different consumer needs while driving towards greener solutions.
