Automotive Fuel Ratings, Certification and Posting
This is a question for clarification, and not a substantive comment. i am having difficulty understanding the ratings requirments. Last week, a book review was posted in the New York Times science section which seemed to indicate that biofuels do not count against the fuel efficiency rating requirement, and the author implied that auto manufacturers were using biofuels to skirt efficiency requirements. Is this accurate, and is this what this proposal seeks to address. Thanks, i have no business interest in this information, it is just personal curiosity. This is the link to the book review (also attached.) -Jeff Cohan
