It's got more horsepower than any other mid-size pickup.
All new (well 93% new) 3.8l V6 with a 9 speed auto. 310hp (class leading) and 281 ft-lbs. I couldn't find any MPG estimates. I am interested to read some reviews on the new powertrain once they come out.
No more 4 cylinder and no more manual transmission.
Edit: TFL says they were told 10% more fuel efficient so 18 or 19 combined for the 4wd with maybe 25+ hwy for the 2wd.
