The idea is to simply have greater transparency for consumers in fuel efficiency ratings. This is an idea that has been developed already in things like EnerGuide, which does a rating. We are essentially proposing that we establish a rating system that deals with two criteria.
First is the vehicle's performance relative to the best and worst in its own class--for example, if it's a small compact. Second is how it ranks with the best and the worst overall for fuel efficiency. It's simply a labelling scheme to allow consumers a better choice, as they have with appliances, for example.
