The annual Renewable Fuels Association (RFA) analysis of vehicle owner’s manuals and warranty statements finds almost all new 2021 automobiles are approved for E15 gasoline, but very limited offerings for flex fuel vehicles (FFVs) capable of operating on fuel blends containing up to 85% ethanol.

Only Ford and General Motors are offering FFVs in model year 2021 with 11 models available, five of which are models available only to fleet purchasers. That’s down from more than 80 different models from eight manufacturers being available to consumers as recently as model year 2015. See what models are FFV compatible

RFA President and CEO Geoff Cooper says they continue to strongly advocate for the production of more FFVs and fairness in how alternative fuel vehicles are incentivized under fuel economy and greenhouse gas regulations. “Consumer demand for E85 and other flex fuels is at an all-time high, meaning drivers are looking for more—not fewer—FFV options on dealership lots across the nation,” said Cooper. “Unfortunately, however, EPA’s latest vehicle emissions regulations essentially eliminate the automaker incentive to build FFVs, while at the same time heaping incentives on automakers who build electric vehicles.”

The good news for drivers is that manufacturers responsible for nearly 95 percent of U.S. light-duty vehicle sales unequivocally approve the use of E15 in their model year 2021 automobiles. For the 10th consecutive year, all new General Motors vehicles are clearly approved to use E15, while Ford has explicitly endorsed E15 in nine straight model years. Among major automakers, only Mercedes-Benz, Mazda, Mitsubishi, and Volvo do not mention E15 as an approved fuel, while BMW and Mini vehicles approve the use of up to E25 blends in all models.
