There are no proposed laws mandating minimum fuel economy standards. While CAFE is a dumb way to try and use less gasoline, it isn't that dumb. CAFE is an average for the entire company, so everything from the Volt to the Regal to the CTS-V gets added together. The basics are that you take the fuel economy of a car and multiply it by the number of those cars sold. Add it up for all the vehicles sold, then divide by the total number of vehicles sold. Now, how they calculate a particular cars CAFE score is a little complicated since it isn't based on the EPA window sticker. But roughly, it will equate to the highway rating you see.

And regarding the fear of losing V8's, the Camaro SS gets about the same fuel economy as some high performance 4bangers and is a little behind some V6 coupes. The Chevy Small Block will enter its 5th generation soon with a 10-15% estimated increase in fuel efficiency. Lastly, cars that have a longer wheelbase and wider track width than average get a little compensation for their CAFE score. They are allowed to be a little less efficient without hurting the overall corporate average. Conversely, smaller than average 'footprints' will be expected to be more efficient. The ~300 hp turbocharged cars like the Evo or WRX are in much more danger than V8 Camaros.
