2011 is a great year for a new truck, the F250s are amazing with their new 6.7L Diesel, and now even better since Ford upped the power of them to 400hp and 800lbs of torque!
2011 F150s now get 4 new engines, 3.7 303hp, 5.0 360hp, 6.2 411hp, and the 3.5TT with unknown hp now, but most likly around 400hp.
The Raptor or any F150 for that matter won't go diesel, Ford scrapped their small diesel in favor of the much cheaper 3.5TT gas engine. The Raptor will contiune with the Hurricane 6.2L.
