3.5L twin turbo "Ecoboost". 3.73 gears w. electronic locking diff. 4x4, of course.
Didn't know Ford was putting lockers on the F150. Got stuck in a one wheel drive F150 back in the 90's out SW of Dryden, Tx. once. Took the men in green (BP) came out there and saved my butt. I was walking out. Wrecker to get me out and moving again.
