E85 gas is suitable for use in flexible fuel vehicles. Flexible fuel vehicles are those that have internal combustion engines and the capability to operate on gasoline with a high ethanol content.
There are an estimated 17.5 million flexible-fuel cars on U.S. roads, but many owners do not realize their vehicle is compatible with E85, according to the U.S. Department of Energy. Flexible fuel vehicles are cars with one fueling system, constructed of ethanol-compatible components, complemented by a powertrain controller that is calibrated to accommodate higher levels of oxygen. Other than the difference in the fuel system and calibration details, E85 compatible cars are the same as conventional gas counterparts. The U.S. Department of Energy offers an Alternative Fuel and Advanced Vehicle Search that lists vehicles such as the Audi A4 Quattro, Chevrolet Impala and Buick Regal as E85 compatible.
There are 21 vehicle manufacturers that offer flexible fuel vehicles including Audi, Citroen and Dacia. The Ford, GM and Chrysler Group have released multiple U.S. Centric models such as the Dodge Journey, Ford E-Series vans and Chevrolet Silverado that can all run on E85 gas.
On E85Vehicles.com, vehicle type is one way to classify the cars listed. Pickups including the GMC Sierra are E85 compatible, alongside convertibles including the Bentley Continental GT. Chevrolet and Dodge models fall into the Crossovers group, with many new models compatible with E85 fuel. There is even a commercial mower from John Deere that can use E85 gas.
