The present invention relates to clean fuel, in particular to automotive ethanol gasoline and a preparation method thereof. The automotive ethanol gasoline is composed of the following ingredients in the weight percentage: 15.0 percent to 25.0 percent of industrial alcohol; 0.60 percent to 5.0 percent of isopropanol; 30.0 percent to 50.0 percent of gasoline; 29.0 percent to 45.0 percent of methylal; 4.0 percent to 15.0 percent of tertiary butyl alcohol; 2.0 percent to 10.0 percent of diisopropyl ether; and 1 percent to 5 percent of naphtha; after the ingredients are mixed, 1 percent to 6 percent of active floridin is added; and after stirring, physical and chemical reactions and filtration, the automotive ethanol gasoline is prepared. The automotive ethanol gasoline is characterized by high octane value and strong explosive force, the production cost is reduced, the emitted tail gas is smokeless and smellless, therefore the pollution of the automotive tail gas is reduced, and moreover, the automotive ethanol
