The frame is still made out of steel. The cab, body, and cargo area will be made out of a high grade aluminum alloy in 2015. The vehicle's weight will be 700 lbs lighter for better fuel economy, without hurting performance. 2.7 liter engine . Ford as well as shareholders, hopes sales will "take off." Ford officials couldn't be reached for comment, as they were on a soda break LOL.
Other manufactures have been using aluminum engine cradles for several years now. I just worry about durability and cracks developing in vibration and stress areas. Maybe they have ironed that out.
