General Motors (GM), Ford, and Chrysler have produced many different models of flex-fuel vehicles (cars and light trucks) over the last five years. In 2011, the number of models offered by those three manufacturers grew and other manufacturers joined them in producing flex-fuel vehicles. The number of flex-fuel models offered to the public doubled from 2010 to 2011. The manufacturers receive credits in the Federal Corporate Average Fuel Economy program for producing flex-fuel vehicles, which run on E-85, a blend of 85% ethanol and 15% gasoline, and/or gasoline.
