>From the way i understand it ethanol has less bang for the buck than gasoline (doesn't everything?) but it can stand much higher compression ratios before detonating. Therefore one could swap out their pistons and maximize their compression ratios for each tank depending on how much ethanol they got or buy a CX650 Turbo and up the boost accordingly. Actually, I think volvo does this, other newer cars just fiddle with the timing. Either way, unless the engine was built with ethanol in mind from the factory it won't be as efficient as straight gasoline. If you wanna pour moonshine in your tank that's fine by me, but it irks me when some suit in DC decides what's best for me and mine.
