Mumbai has joined Delhi in the list of cities offering E85 fuel. The high-ethanol blended fuel is now available in the city at Rs 91.18 per litre, making it almost Rs 9 more expensive than Delhi, where E85 is currently sold at a lower price. E85 is a fuel mixture consisting of 85 percent ethanol and 15 percent gasoline. It is intended for flex fuel vehicles that are specifically designed to run on high ethanol blends. The fuel is also significantly cheaper than the E20 gasoline currently sold nationwide. In Mumbai, E20 petrol is priced at Rs 111.33 per litre, which means drivers using compatible vehicles can save more than Rs 20 per liter by opting for E85. The introduction of E85 is part of a broader government strategy to reduce crude oil imports, support domestic ethanol production and reduce tailpipe emissions. Ethanol is primarily produced from agricultural raw materials such as sugar cane and corn, making it a renewable alternative to conventional fossil fuels.However, the biggest challenge remains vehicle compatibility. Currently, only a few models sold in India can run on E85. Maruti Suzuki recently launched the WagonR Bioflex, making it the country’s first flex-fuel passenger vehicle. Priced at Rs 7.24 lakh, ex-showroom, the hatchback is powered by a 1.2-litre four-cylinder K12N petrol engine that can run on ethanol blends ranging from E20 all the way up to E100. In the two-wheeler segment, Hero MotoCorp has introduced Splendor+ Flex Fuel and HF Deluxe Flex Fuel. Both motorcycles can run on E85 fuel. Suzuki also sells a flex fuel compatible version of the Gixxer SF 250 in India.
