Rename this sub-forum to "2015-2017 Ford F-150"?
 

I take it back. I don't care. I don't have to deal with cleaning up arguments which will increase. Have fun mods :)

I dont think the 2018 model year would be considered a new Generation. Probably the next gen would be 2020/2021. The 2018 is just a re-fresh, kinda like the Mustang between 2012/2013 and 2017/ 2018

Correct. 2018 F-150 will keep the same P552 name code at Ford. 2018 is not a new generation of F-150 and doesn't need a separate subforum.

Well not only is it a facelift, but there's engine and transmission changes across the entire lineup.

Any time this happens, it's labeled a new generation : https://en.wikipedia.org/wiki/Ford_F-Series

The 2017 has the gen 2 EB and 10 speed

Right, but with the 2018, they all have 10-speeds except the new entry 3.3L engine, they now have a diesel (also 10-speed), and all engines with the 10-speeds have stop/start including the 5.0 and diesel. The 3 current engines have also been changed and improved.

3.5 and 2.7 are already offered in 2017, although the 2.7 is supposed to have some fuel delivery changes from what I understand.

10 speed is already available in 2017.

Start/stop is already on select 2017's.

Other than a new diesel option, the rest is pretty much a "face and butt lift".

Seems evolutionary rather than revolutionary to me....

I'd wait until the '18s hit the aftermarket and we all know what parts interchange, or don't, then it should be decided whether to split.

There was new engines between 2010 and 2011, but that wasn't consider a new generation either

Whenever there is change to the body or engine I too would think it's the newest generation. Maybe using the same chassis yes, but whole different build and components. Now to keep up with other vehicles a "refresh" is done to compete with other companies
