Given that Germany is already using 100% biodiesel in many of its cars and many European countries commonly have significant proportions of biodiesel blended in their diesel, it is curious that EPA is still struggling with 15% ethanol blend in gasoline.  This just further highlights the innovation gap between the U.S. automakers and their competitors across the pond.  

What is also worrying is that it is the automakers who have influenced the delay and not the environmentalists.  Does the corn lobby still dictate what is environmentally friendly and what is not?
