Ford has an all aluminum body for the new F150 which will reduce weight and improve mileage.
My 4.7 gets 23 highway - not towing. 14 when I'm pulling a trailer. It's got more umph than my old 5.2 (318cid). It's a baby Hemi with two plugs/cylinder.
It can burn anything - E10 up to E85 - but that's when the mileage plummets to 11/16.
My 5.7 Hemi got 12/17 - exactly the same as my 360cid.
That is a special 4.7 that you have there. I have never heard of anyone getting near that MPG in it. What vehicle is it in?
From what I understand, the 4.7 is far from a baby Hemi. EPA ratings were identical, or slightly favorable to the Hemi. I had a 4.7 in a Grand Cherokee (1998?), and my experience was no difference in MPG vs the 2005 Hemi GC I had, with the Hemi having somewhere in the neighborhood of 100 HP advantage. I think in the last years of the 4.7 that advantage was closer to 50 HP, still significant.
I have no interest in burning anything over E10 or E15 when that is forced on me. I agree with you that E85 MPG plumets.
