Ethanol Blends: Providing a Renewable Fuel Choice

Research output: NRELFact Sheet


Today, more than 21 million vehicles on U.S. roads are flexible-fuel vehicles (FFVs). These vehicles can operate on either gasoline or blends of gasoline and ethanol up to E85 (a gasoline-ethanol blend containing 51% to 83% ethanol). As a renewable fuel, ethanol offers significant advantages. It is produced predominantly in the United States, made from home-grown feedstocks, and burns cleaner than gasoline.
