They don't have an EPA rating on it yet but they're looking for 24 highway. They also removed a lot of weight from the truck (about 100kg) by using aluminum in the hood, suspension and bed, 8 speed gear box is also lighter than the old 6 spd. Also has electric PS and a lot of aero tweaks. Its funny how the manufacturers seem to have no problem finding huge FE gains now that fuel prices are forcing them to do it. A few years ago they were blathering on that higher CAFE standards would kill jobs. What a bunch of BS.
