eFlexFuel has introduced an E85 Flex Fuel Kit for Chevrolet Silverado and GMC Sierra models from 2014 to 2019, allowing drivers to retrofit their pickups for E85 use. This complete ethanol flex fuel system is compatible with the flex mapping technology in the engine control units of these models, enabling drivers to seamlessly switch between gas and ethanol. The benefits of using E85 include increased power, torque, and horsepower, along with lower temperatures in the cylinders and cleaner emissions. The fuel is also cheaper than traditional options, making it appealing for those who use their trucks for work or long-distance travel. Additionally, Toyota is making strides in the flex fuel market with its plan to launch the ethanol-powered HyCross in India, introducing flex-fuel hybrid technology to the country. While there are pros like reduced greenhouse gas emissions and support for renewable fuel industries, there might be a slight compromise on fuel economy. The process of upgrading to flex fuel is relatively simple and does not require retuning the ECU. With a growing network of E85 fuel stations in the US, refueling has become more convenient for drivers with flex fuel vehicles. The eFlexFuel kit also allows drivers to fill up with regular gas when needed. Other auto companies are also offering similar flex fuel upgrades, showing a positive trend towards more environmentally friendly vehicle options.
