According to at least one resource I've read, gasoline is only moderately better at well-to-tank efficiency than alcohol - 80% vs 60%. Interestingly, both of these are better than grid electricity.

I think an engine that was idealized for alcohol consumption from the outset would deliver much better fuel economy than the flex-fuel models. Let's ask Cripple Rooster, Brazil has a long history of domestic alcohol fuel production.
