Last I recall, the CAFE standards only applied to trucks and cars with a GVWR of 8,500 LBS. or less. Otherwise we'd see MPG ratings on our window stickers.I've never seen a SD rated for fuel economy either. Regardless there is hardly any mpg difference between 3.73, 4.10 and 4.30 gears for the modulars. The 6.2l doesn't seem to suffer much mpg wise with 4.30s. I remember reading something (I think from the 6.2l thread with the Ford engineer) that the SDs were included in a part of the CAFE standards. Who knows. With the gooberment everything is giant PITA and nobody knows whats going on, including the beaurocrats that drafted and passed the law.

In order to keep this "politics free", I'll just post the link without quoting anything. It's a pretty good read that spells out what qualifies under CAFE and what doesn't.
C A F E Overview
Who knows though. There's probably something in there hidden away so that the average layperson can't find it.
