The Energy Information Administration publishes estimates of the number of alternative fuel vehicles (AFVs) in use. Vehicles running on E85 make up the majority of AFVs, with 450,327 vehicles in 2008. That figure, however, only accounts for the portion of E85 vehicles that are believed to be typically using E85. Through 2007, about 7.1 million vehicles had been sold that are capable of operating on E85, but the majority of those vehicles are using traditional gasoline.
