The 6.2 had terrible everyday mpg compared to the 3.5tt.

If you want to compare the 2.7,5.0,3.5 as grocery getters and always empty I suppose you could.

But why not compare them as they were intended?

1. 3.5 They can either barely afford an f150 or They only have a truck for (name your reason). But 0 work.
2. 2.7 tows what most want, either likes tech or doesn't hurt, and really amazing mpg, and power for a truck.
3. 5.0 Old timers "have to have a v8 don't trust those snails only v8s last bla bla bla.
4. 3.5tt truly amazing towing extremely leisurely towing unlike the v8 screaming to tow it's maximum. Plus when you've got 2k in the bed and your trying to climb a hill you you really want to lay into the throttle? The 3.5 will climb that hill at 2500 rpm with the full 420 soon to be 470tq.

I owned a crew 4x4 2002 with the 5.4. Loved to scream while towing. Absolutely wore me out.

Pretty much a wash between them in 16, which is why Ford is uping the power on the 3.5 EB for 17.

And keep in mind ford does not think they are competing with their own engines. It wasn't time to add power to the ecoboost because of the 5.0.

They compete directly with the gm twins and to a lesser extent dodge. Hense the 10 more ft pound tq than gms 6.2 puts out.

All engines every so many years get updated to keep up with the joneses or get discontinued. It was just the 3.5tt turn. Just like the 5.0 had just a couple years back.

That's why at the end of the day, the needs and preferences of the driver determine which engine is best.
