There was no 4 cylinder turbo in 2017 for the F150.
There was a 2.7L 6 cylinder eco-boost (turbo), 325 horsepower and 375 lb-ft of torque.
There was a 3.5L 6 cylinder eco-boost (turbo), 375 horsepower and 470 lb-ft of torque.
There was a 3.5L 6 cylinder high output eco-boost (turbo), 450 horsepower and 510 lb-ft of torque. (On the Raptor).
There was a 5.0L 8 cylinder NA, 385 horsepower and 387 lb-ft of torque.
There was a 3.5L 6 cylinder NA, 282 horsepower and 253 lb-ft of torque. (This was the base engine on the XL.)
I have a 2015 w/115K miles on it (3.5L eco-boost) and it has gotten close to 20 MPG overall - including towing a 20' trailer w/tractor, being filled with wood, multiple long trips pulling u-hauls, and having studded snows on it every winter.
Having said this, I have (had as I just sold the Maverick) both. If I were pulling a 17' sailboat/trailer at 3k, I would much rather have the F150 doing it rather than the 2.5L Maverick Hybrid.
ETA: The Maverick's non-hybrid engine is the 2.0L Turbo. Perhaps you were thinking of that? I also have that engine in a 21 Bronco Sport Badlands. It is quite peppy on that little thing.
