The biggest flaw of the fuel ethanol industry isn't the product they produce, but the business model they've chosen. Had the industry spent as much money on bringing an ethanol optimized engine to market as they have on convincing the government to eliminate market choices, it might produce a viable product.
“Had the industry spent as much money on bringing an ethanol optimized engine to market as they have on convincing the government to eliminate market choices, it might produce a viable product.”
Very interesting point you bring up. Since 2006 apparently there is a computer switch, within the vehicle brain, that allows multiple fuel use. There are those in the wings that would like to see methanol (straight) as a fuel, and the computer switch would allow it, E-85, biodiesel, and much greater alcohol percentages to run, with some fuel system mods to avoid corrosion.
At the moment the unfortunate point is the switch is off from the factory, and getting it turned on from the factory involves convincing a bunch of lobbyists from the oil industry it is a good idea. They will probably think otherwise.
